TXP is comprised of 4 different sub-systems: AS620, OM650, ES680, and DS670 which are all connected together with the Bus System Industrial Ethernet. AS620 The AS620 (Automation System) interfaces to the process. It acquires measured values, performs the open & closed-loop control functions, and transfers the resulting commands to the process. OM650 The OM650 (Operating & Monitoring) system component handles tasks associated with process control, process management, and process information. The functions are provided for the user via a uniform desktop interface based on the X/Windows and OSF-Motif standards. ES680 The ES680 (Engineering System) is the integrated, uniform planning and commissioning tool of the TXP process control system. It is used for the engineering of the other subsystems. DS670 The DS670 (Diagnostics System) provides all the functions that are required on a central or distributed diagnostics terminal for the detailed monitoring and diagnostics of the AS, OM, LAN, and DS (self-diagnostics) system components.

AS620 meets all the characteristic automation requirements for a power plant with just three system types:

AS620 B For general automation tasks ranging from the protection of an auxiliary subsystem right through to overall plant control. Apart from the classical central configuration in sub-racks, a distributed configuration in the plant using field-buses is also possible. AS620 F For protection tasks important for safety, such as at the boiler and safety controls that are subject to licensing requirements. AS620 T For the fast closed-loop control functions of turbine I&C (SIMADYN). Interfacing to SIMATIC S5/S7 permits the ancillary system I&C, which is not necessarily included in the scope of supply of the main I&C supplier, to be seamlessly linked to the process control system.

Interfacing to the process takes place via I/O modules to which the I/O comprising measurement transmitters and actuators are connected. Two module types are available in AS620 to support a central or a distributed configuration: • FUM modules (function modules) for central configurations • SIM modules (signal modules) for distributed configurations

FUM modules FUM modules have been specially developed for power plant applications. Within the context of the higher I&C levels, the FUMs are equipped with preprocessing units with medium to high processing performance. The most important FUM tasks are: • Signal acquisition, conditioning, processing, monitoring, and sensor supply • Individual open and closed-loop controls • Time tagging with 1 ms resolution for events (both analog and binary) FUM modules are inserted into sub-racks that are mounted in electronics cabinets and are linked to the AP via the cabinet bus

SIM modules SIM modules are used for the input and output of analog and binary signals. Their task is to digitize process signals and to output digital settings as binary or analog signals. More complex tasks such as signal processing, monitoring, and time-tagging are performed in the AP. A signal module in conjunction with the associated function block performs the same function as the corresponding FUM. SIMs are modules from the SIMATIC S5/S7, ET200 B/ET200 M range, which allows the input and output modules to be installed locally in the process environment instead of centrally in the automation system. For this purpose, the modules are combined into stations and located in the immediate vicinity of the field devices, installed in distribution boxes or wall-mounted housings for example. The advantage of a distributed configuration lies in the minimal space requirements in the computer room, because only the cabinets for the AP are installed there. Savings can also be made in wiring costs because only the loop-in cable from the I/O to the nearest station is required. Distributed configurations also permit the automation processors and the input and output modules in the process environment to be located a considerable distance apart. The SIM modules are linked with the automation processor via PROFIBUS. PROFIBUS can be operated at a maximum data transmission rate of 1.5 Mbit/s and is also available in a fiber-optic version for use under adverse interference conditions or where lightning protection is required. The flexibility of the automation system allows the FUM structure to be combined with the distributed SIM structure, which supports the implementation of tailor-made solutions.

TXP-CLC Course

Industrial Ethernet designed to be used asplant bus and terminal bus

The bus system in TXP comprises two separate buses, the terminal bus and the plant bus. This allows de-coupling of the distinct communications procedures. Communication between the automation systems and between the AS620, the processing unit (OM650/PU), ES680, and DS670 takes place via the plant bus. Communication between the OM650/PU/SU, ES680, DS670, and the OT’s takes place via the terminal bus. The SIMATIC NET™ Industrial Ethernet can be implemented in both cases. The system architecture comprises: • The transfer medium that implements the physical structure of the bus

with the appropriate connection and transfer components • Active bus components via which TXP participants are connected to the

bus • Communications protocols that support the structured exchange of data

between TXP participants • Configured links that describe communications applications between TXP

participants The CSMA/CD (Carrier Sense Multiple Access with Collision Detection) access procedure is used on the bus system uniformly by all TXP participants independent of the physical variants of the bus (drop cable, industrial twisted pair or fiber-optic cable).

The central components of the Industrial Ethernet bus are star couplers that are

connected together via optical paths to form a ring, which is referred to as the

virtual ring.

The bus itself, that is the link between the star couplers, is implemented with an

optical transfer medium. The participants are connected to the star coupler via an

electrical transfer medium or a combined electrical and optical transfer medium.

Industrial Ethernet Bus System design and mode ofoperation

As stated previously, the star couplers are connected via fiber-optic cables to

form a ring. One of these connecting paths is a redundant optical path that is

disconnected by monitoring logic. The line structure of the bus is, therefore,

maintained. The bus signals are monitored constantly on each side of the

disconnection by the monitoring logic on the optical interface cards. A special

module is not required for the monitoring logic, it is implemented in the optical

interface cards that are used as standard. The monitoring function is activated on

the interface cards at each end of the redundant optical path by toggling a DIP

switch.

➣➣

➣➣



Provided that the bus system is operating error-free, the data packets from a

transmitting participant are transferred over the entire length of the bus and the

monitoring logic receives identical bus signals from both directions. In the event

of a fault, such as a wire-break or failure or shutdown of a star coupler, the data

stream is not received from one direction. Data is not received temporarily by

participants that are connected between the location of the fault and the module

that contains the monitoring logic.

The monitoring logic responds by connecting the open circuit within the module,

so that all participants are able to communicate with each other once more.

When the fault that interrupted the transfer path has been rectified, the virtual

ring is re-established in that the monitoring logic disconnects the path again. With

a virtual ring, single-fault tolerance can be achieved that is comparable to a bus

system that is implemented with a redundant transfer medium without the need

to implement a second transfer medium. One fault in the cable of the virtual ring

is tolerated.

transtransmittermitter

In TXP, a system-wide, uniform time is kept by a time transmitter, from which

time-tags are obtained for marking events. The time-of-day is distributed via the

time transmitter over the plant bus.

The time-of-day transmitter is used for time synchronization of the TXP

subsystems AS620, OM650, and DS670 and it transmits time-of-day messages

over the plant bus at intervals of 10 seconds which are received and evaluated

by the connected TXP participants.

The time-of-day transmitter is only implemented on the plant bus; time is

transferred to the participants connected to the terminal bus via the PU. The

time-of-day transmitter can be synchronized via other clocks or it can be used to

synchronize other clocks.

Time-of-day synchronization can also be implemented via one of the

communications processors in the AS620 subsystems (CP1430).

The ES680 engineering system is the integrated, uniform planning and commissioning tool of TXP. It is implemented in all phases of project engineering: • Task definition • Detailed engineering • Commissioning and maintenance of the I&C on the customer site ES680 is used for the engineering of the following subsystems of TXP: • OM650 (operating and monitoring system) • AS620 B (automation system) • Bus system (SINEC Industrial Ethernet) The data required for the DS670 diagnostics system is extracted from this engineering data. ES680 is a graphical system based on a database and relies on internationally available and standardized software components. Data is only ever entered once system-wide and is presented to the appropriate components of ES680 during the engineering process, checked and consistent. The hardware platforms used are Hewlett Packard HP workstations with HP-UX version 10 or SCO UNIX PCs with SCO version 5.

Engineering takes place via a graphical user interface with standard displays.

During the initial engineering phase, customer specifications (e.g. P&I diagrams),

the control room concept, and the plant configuration are loaded into ES680.

The data generated in ES680 is stored on the hard disk and is always up-to-date

(forward engineering). Following commissioning or after modification, data is

stored on external data carriers (e.g. on CD or magnetic tape) for back-up

purposes. The data can be called up in ES680 from the hard disk at any time for

modification or diagnosis (paperless documentation). Printouts can be obtained

for special external investigations or for paper documentation.

Standard blocks are available in the form of symbols for creating and modifying

function diagrams. The symbols are assigned to the individual levels and

functions. This prevents symbols being entered in levels in which they do not

perform a function.

The symbols are placed in the diagram using the “drag & drop” principle (click

symbol in the symbol bar, drag it into the desk-top, and place it at the desired

location).

Function blocks are connected simply by drawing connecting lines from one

symbol port to another symbol port. Invalid connections are rejected immediately.

Screen forms are available for parameterizing the function blocks. Internal

parameters such as delay time and controller parameters can be set in these

screen forms. Many basic definitions are preset with defaults, so that changes

only have to be made in these windows for special applications.

All changes to the task definition are also entered via the function diagram and

converted by the engineering system into the system- specific code. This method

of consistent forward documentation ensures that the data is always consistent in

the AS and OM.

Dynamic function diagrams are an indispensable aid during commissioning for

fault analysis and for detecting engineering mistakes. They allow the I&C

engineer or commissioning engineer to display current values (binary and

analog) directly in the function diagram. The input and output signals and logic

circuit outputs are displayed. This supports rapid, detailed error localization.

Corrections can be implemented directly in the function diagram and can be

checked immediately after transfer.

The “fast parameter change” function allows the user to modify parameters in the

function diagram and then observe the result, or effects in the function diagram.

Dynamizing has to be switched on for this purpose and the function block

parameter window has to be opened. The parameters are adjusted and, following

confirmation, they are directly transferred to the AS. The result is then

immediately visible.

Simulation is also available in the dynamic mode in two ways:

Simulation of process signals (inputs of the FUM/SIM modules)

Simulation using blocks (a block with a switch can be switched between the

simulated value and the signal)

Both binary and analog values can be simulated.

Introduction The KKS, or Power Plant Classification System is used by Siemens Westinghouse to identify equipment used for the Combustion Turbine. The use of this system in conjunction with the Combustion Turbine will be described in a general manner in this document. More detailed information about the KKS system can be found in the official publications from Siemens Westinghouse. KKS Identification The KKS tagging system includes three types of identification: • Process Identification • Mounting Location Identification • Room Identification In the Combustion Turbine documentation, process Identification is identified by the prefix "=" and identification of mounting location is identified by the prefix “+". For I&C documents this can usually be found in the title block in the lower right-hand corner of the drawing. KKS Structure KKS Levels The KKS tagging system also provides a means to identify various levels of devices within the power plant. These are broken down into four different levels: • Level 0 Total Plant, i.e. Unit 11 or Unit 12 • Level 1 Function Key, i.e. Gas Turbine or Cooling Water • Level 2 Equipment Code, i.e. Pumps or Actuators • Level 3 Component or Signal, i.e. Relays or Switches KKS Tag Numbering The numbering used in the various levels of the KKS tagging system is assigned when the design phase is being done. These numbers may be assigned to represent a function or a particular piece of equipment.

KKS Structure Example In Figure 1 an example of a KKS structure is shown. The number used identifies the Closed Limit Switch for the Turning Gear Valve for Unit 11. The level break down is listed below: • Level 0 Unit , Unit 11 • Level 1 Function, Turning Gear System • Level 2 Equipment Code, Electrical Actuator 1 • Level 3 Electrical Component or Signal Identifier For Level 3 the prefix “-“ indicates an electrical component, Closed Limit Switch .

Process Identification Example In Figure 2 an example of a KKS structure for process identification is shown. The number used is for the Turning Gear Valve. The prefix "=" identifies this as a process related number. This type of number would normally be seen in the title block of a drawing, which is located in the lower right-hand corner. Drawings are organized within the I&C manuals alpha-numerically using the prefix “=”. If an addition character is added after the Equipment Code, i.e. MBU31 AA001A, this is used to indicate an additional device besides the main device. In the case of measuring instruments an additional character may be used to identify multiple elements within one device, i.e. a three element thermocouple.

Identification of Mounting Location Example In Figure 3 an example of a KKS structure for identification of mounting location is shown. The prefix "+" is used to represent mounting location information. The "." between CJP02 and DC015 is used to identify that DC015 is a module location within the cabinet CJP02. This identifier is used in the I&C manuals.

Figure 3 shows the overall structure of the KKS mounting location, but in most cases the numbers used within the drawings are abbreviated in some form or another. The following list provides some other examples of mounting locations that are commonly used in the I&C manuals: +CJP02 This type of number is normally used to identify the cabinet. It can

be found in the drawing title block or on the drawing itself. The prefix "+” in this case represents the unit number in which this drawing pertains.

+.DC015 This type of number is used to identify a module. The prefix "+” in

this case represents both the Unit and the cabinet number. The cabinet number in these cases can be found in the title block of the drawing.

+.XD007 This type of number is used to identify a Termi-point connection.

Below this number the letters A to H would be listed to show connection points for the individual signal. The prefix "+" in this case represents both the Unit and the cabinet number in which the termi-point is physically located. The cabinet number in these cases can be found in the title block of the drawing.

KKS for Documentation The KKS identification system is not only used for equipment but also for documentation. This includes identification codes for documentation and signal standards. Identification Codes for Documentation The KKS system includes identification codes for documentation, which allows a way to link documentation with equipment. Function codes, equipment codes, documentation types, and drawing types are all used to identify the documentation associated with a piece of equipment. An example of a documentation identification code is shown in Figure 5. The documentation identification code is usually found in the drawing title block. Documentation Identification Code

Drawing Type or Serial Number The Drawing Type or Serial Number field defines the type of drawing. This is sometimes a particular type of drawing identified by a letter. Or, in other cases a serial number is assigned to the drawing. The drawing types used in the KKS system are listed below. The drawing type can usually be found in the title block for each drawing.

Signal Code The KKS system incorporates a signal code, which allows the consistent identification of signals. The signal code is a suffix of the KKS code, which identifies the type of switching element used to create the signal. Figure 6 shows an example of the signal identification code:

Figure 6 - Signal Code

Initial Character The initial character of the signal code is used to identify the type of signal being identified. The only two characters that are used are listed below: X Signal from a specific signal area, this means a signal that comes directly

from a switch for example. Z Gated signal from a specific signal area, this means a signal that comes

from the output of an AND gate for example. The creation of this signal is from previous logic.


22 22

Signal Area The signal area of the signal code is used to identify the signal source. The different signal areas are defined below: -A Function group control, sub-loop control -B Control interface -C Conventional closed-loop control -G Binary signals conditioned by an input module -H Binary signals created by a limit value monitor -J Non-floating signals, not coming from specific signal area, i.e. a black box -K Protection systems -L Control room and control stations -M Non-floating individual and group alarms -N Status display computer, criteria indication -P Supervisory computer -Q Analog signals -R Major closed-loop control, in addition to B and T -S Step signal from a functional group control -T Turbine instrumentation and control signals -V Protective logic -W Hard-wired alarm system - indicates the initial character, either X or Z Serial Number The serial numbers used for the signal code range from 01 to 99. When the initial character X is used the serial number assigned has a special meaning depending on the type of signal being defined. For the initial character Z the serial number follows no special rules. A listing of the serial numbers assigned for each signal area is given in Signal and Application Area Assignments below.


23

TXP CLC Course

XG or ZG - Binary signals conditioned by an Input module Normally open contact (NOC) & normally closed contact (NCC) Signals in this signal area originate from a floating contact, i.e. switch or relay contact. The serial numbers are assigned depending on the type of floating contact. The type of floating contacts include: normally open contacts (NOC) and normally closed contacts (NCC). A definition of each according to the KKS system is given below: NOC Normally open contact; the switching element is in the normally open

state when the... - switch is not mechanically actuated - relay is dropped out or de-energized The contact will close when the... - switch is mechanically actuated - relay is picked up or energized NCC Normally closed contact; the switching element is in the normally

closed state when the... - switch is not mechanically, actuated - relay is dropped out or de-energized The contact will open when the...

- switch is mechanically actuated - relay is picked up or energized

Serial number assignments for NOC and NCC The KKS system assigns a different range of serial numbers to signals in the XG and ZG signal areas depending on the type of contact used. In the following explanations only the XG signal area is mentioned, although the same rules apply for the ZG signal area. The serial numbers 01 to 49 are assigned to signals which are derived from normally open contacts (NOC). The serial numbers 51 to 99 are assigned to signals which are derived from normally closed contacts (NCC).

Serial number assignments for MIN and MAX MIN signals are generated from set points below a median value of an analog signal range. MAX signals are generated from set points above the median of an analog signal range. To separate between MIN and MAX signals the following rules apply: MIN even serial numbers NOC = 02, 04, ... 48 NCC = 52, 54, ... 98 MAX odd serial numbers NOC = 01, 03, ... 49 NCC = 51, 53, ... 99 For a switching device that has both a NOC and a NCC, (changeover contacts), the serial numbers would be assigned with a difference of 50 between them, i.e. XG01 - XG51 or XG02 - XG52.

TXP CLC Course

MIN limit value For a MIN limit value the switching point is obtained by changing the measured variable in relation to a minimum value, i.e. < MIN. For the MIN limit value the < MIN signal is derived from the NCC of the switching device. Figure 8 and 9 show examples of < MIN signals for pressure and level. The < MIN signals are assigned serial numbers of XG52 and NOT MIN signals are assigned serial numbers of XG02. MIN NOT MIN XG52 XG02 XG52 XG02

TXP CLC Course MAX limit value For a MAX limit value the switching point is obtained by changing the measured variable in relation to a maximum value, i.e. > MAX. For the MAX limit value the > MAX signal is derived from the NOC of the switching device. Figures 10 and 11 show examples of > MAX signals for pressure and level. The > MAX signals are assigned serial numbers of XG01 and NOT MAX signals are assigned serial numbers of XG51.

Initial Character Z or X If there are more than one switching elements connected to an input (hardwired OR) then the initial character Z would be used. Figure 12 shows a > MAX signal derived from two NOCs. The serial number assigned to this signal is ZG01. If only one switching element is connected to an input then the initial character X is used; this is shown in Figure 11. ZG01 NOT MAX MAX Level Level NOC NCC Tank 1 Tank 2 Figure 12 - MAX Signal (Level) - ZG01 XH or ZH - Binary signals from a limit value monitor The signals created in this signal area are analog values that are monitored by a limit value monitor. The analog signals are compared with a set-point for MIN or MAX. The resulting signals from this type of comparison circuit are defined in the XH signal area.

YN - Status display computer, criteria Indication The application area YN is used for group, subgroup, and sub-loop controls. The serial numbers are assigned sequentially for each step. The signals in this application area are created to indicate missing criteria for a particular step. An additional character "K" is used to indicate that a message will be printed out on the alarm printer if the criteria is missing. XS - Step signals from a functional group control The step signals within this group represent step numbers within a functional group using sequence control. The step signals are divided into two groups, they are: XS01 - XS49 Startup program XS51 - XS99 Shutdown program

Application Code The KKS system incorporates an application code which allows the consistent identification of application or command signals. The application code is a suffix of the KKS code, which identifies the application of the signal being created.

TXP Training Project Engineering Procedure The engineering procedure can be subdivided as follows: -- Entering project data (complete for this training project) -- Drawing equipment structure, AS structure and module structure -- Drawing the ”measurement” function diagrams -- Drawing area and overview diagrams (optional) -- Drawing function diagrams -- Generating the code and transferring to the target system This chapter will only cover the first and second and fourth procedures. The other procedures will be covered in subsequent chapters. 1 Entering the Project Data Before the diagrams are generated, the general project data has to be entered (DB -- Defaults – Project data).In this section you assign the project name, engineer , Power Station, Project number , etc. This information will be added to each function diagram subsequently created in the project.

The functional complexes (major areas of the power plant) are then entered and assigned to users for processing and also to AS numbers (DB -- Defaults -- FB data). This assignment is a default that is used if no data is entered in the function group code (sub-areas of the power plant) mask that has to be completed next (DB--fct. -- Defaults – FGC data). The AS and AP-F numbers that are entered here are defaults that are used when a new diagram is created.

TXP CLC Course 2 Structure diagrams 2.1 Equipment structure diagrams One and only one equipment structure diagram (topology) must exist for each project. It depicts all TXP components that are connected to the LAN and supports automatic allocation of consistent bus addresses. The ID--code ”YDH = OVE001V001” could be used for a topology. The FGC for the topology must exist but has no significance. The name for AS Structure diagram (YDM) is determined from the LAN symbol parameters. The ID code YDM + 00CJF01 could be used for an AS structure drawing. If a YDM diagram does not exist it can be created automatically, and the system allows navigation to it from the topology. The AS structure diagram can be accessed for example via the LAN symbol on the topology. Function block parameter mask entries must always be followed by the enter key, otherwise the entries will not be saved. All symbols on each drawing must be connected with a connecting line in a from / to manner. When the topology is saved, the top.ed program is called automatically to analyses the LAN structure and assigns addresses and sequential numbers to all components that are not already assigned. 2.2 AS structure diagram The AS structure diagram shows the cabinet level structure of the components on the topology diagram. The YDM diagram is function related and is therefore assigned a function group code (e.g.: YPAC01). Each element of this diagram corresponds to a rack level diagram (YDR) that shows an individual rack with it’s module configuration. The ID code for the rack diagram is a mounting location within the equipment ID code (cabinet name), a dot must be entered for the first character of the mounting location (e.g.: 00CJF01.BG). 2.3 Individual level structure diagram The rack structure diagram shows the racks and the individual modules. The part numbers and Input Output (I/O) ID codes and signal ID codes are entered in the parameter mask for I/O assignments. After code generation, navigation will be possible from the YDR drawings to the associated rack level “measurement” logic drawings (YFR).

Functional Specification for training project logic

Lube Oil Heat Exchanger Cooling System 1. Task

1.1 Proper operation of a Gas Turbine requires a minimum lube oil temperature which, most of all, assures proper bearing lubrication and thus prevents destruction of the bearings. A Heat Exchanger is the primary element in the lube oil cooling system. To generate the proper flow across the Heat Exchanger the following equipment is used:

- Main circulation pump (three phase AC pump) 00PAC10AP010 - Auxiliary circulation pump (three phase AC pump) 00PAC10AP020

The operating pump is the main pump and will be turned on by the operator; the auxiliary pump is automatically turned on only if the main pump fails. Downstream of each pump is a solenoid operated back flow prevention valve 00PAC10AA010-ZV01and 00PAC10AA010-ZV01 respectively. These valves will be forced open when the associated pump is on.


3

TXP CLC Course 2. Cooling Water System Concept

2.1 The cooling water system consists of a tank holding the cooled water that is to be circulated through the heat exchanger. Level in the tank is kept constant by a mechanical float valve and is displayed graphically to the operator for monitoring purposes by transmitter 00PAC00CL101-XQ01. This transmitter is also used as a permissive to start either pump only when the level is above 10%.

2.1.1 Ahead of each pump is a filter with a differential pressure switch: 00PAC08CP010-XG51 and 00PAC08CP020-XG51 respectively. They are used to disable their associated pumps when the differential pressure is greater than 2 PSI and notify the operator via an alarm.

2.1.2 The flow is controlled by a 4-20 mA control valve 00PAC20AS151 ZQ01

which has a controller whose output is proportional to the process variable in a range from 150 to 200 degrees Fahrenheit. The process variable is the oil temperature exiting the heat exchanger measured by transmitter 00LAB10CT101-XQ01. If the temperature exceeds 200 degrees Fahrenheit notify the operator via an alarm.

2.1.3 Immediately down stream of the control valve flow is measured with a DP

transmitter 00PAC21CF101-XQ01. This flow measurement is displayed graphically to the operator for monitoring purposes.

3. Emergency Stop Valve Logic 3.1 A Normally Open solenoid valve is located ahead of the Heat Exchanger

for use as an Emergency Stop valve: 00PAC30AA030

3.2 If the tank level drops below 25% the ESV will close

3.3 If the lube oil temperature exceeds 200 degrees Fahrenheit the ESV will

close

3.4 If both pumps are off and there is no flow through the control valve the

ESV will close

3.5 Anytime the ESV is closed the control valve will also be forced open

TXP SIM Function Block

FB70 (BT)

7 General Description The processing of binary signals in the TXP AS 620 B system (SIM version) is carried out using a BT function block (FB70) in conjunction with an ET 200M I/O device (SIM 321 and/or 323). The BT function block and SIM modules are used to: • Provide the supply voltage for 8 changeover contacts (Form C) • Condition the sensor signal • Monitor the input signal • Simulate the logical sensor signal • Output signal faults and channel faults The BT function block establishes the connection between the hardware function plans (YDR) and the automation processor (AP) logic (YFR). It is used to establish a binary signal for use in monitoring and/or process control. In normal operation, the BT references the value of the input signal from the Process Image Input Table (PAED), conditions it and writes it into the status data block (ZUDB). The signal must be defined (SIGDEF) on the individual level logic diagram (function plan / YFR) that is identified with the Power Plant Identification Code (KKS) for the equipment. The signal is then available for use in the AP. The SIGDEF and KKS must match the input channel identifier in the parameter mask of the SIM module on the rack level location drawing for the connection to the input point.

BE/SIG Binary input signal BE/SIGN Inverted binary input signal KSIM Binary input signal simulated KG Binary input signal ok Parameters Name Description GT Sensor type CHAT Chatter transmitter (Sensor chatter detection and alarm) DELAY Input signal delay EBS Default binary signal EIU Input signal monitoring CONV Contact supply Explanation As with most TXP function blocks, the BT block can be parameterized to perform specific tasks within a control scheme. Below is the parameter mask for the BT function block followed by a brief explanation of each output and parameter:


3

TXP CLC Course BE/SIG This output is the value of the binary signal, after all internal processing, that is available for further processing in logic. BE/SIGN This is the value of the inverted binary signal, after all internal processing, that is available for further processing in logic. KSIM This is the simulation indication output. It will be high (logic “1”) when the signal is being simulated. KG This is the channel valid signal output. It will be high (logic “1”) as long as the channel is valid (Internal monitoring logic determines the validity of the signal). GT This parameter defines which type of sensor is connected to the SIM module. There are 7 possible choices in the parameter mask: 0,1,2,3, 4, 5, and 6. Meaning: 0. No sensor type 1. Form C contact with 47k ohm bridging resistor 2. Form C contact without 47k ohm bridging resistor 3. Form A or B contact with 47k ohm bridging resistor 4. Form A or B contact without 47k ohm bridging resistor 5. Three-wire proximity switch (FUM application) 6. Four-wire proximity switch (FUM application) The default setting is 4

CHAT Sensor chatter can be monitored using the CHAT parameter to define the chatter monitoring time. The range of acceptable values is from 0 to 100 seconds where 0 disables chatter monitoring. The default setting is 0. The monitoring function is triggered when more than three changes in signal follow the first change in signal within the parameterized chatter monitoring time. When the chatter monitoring time has expired, it is restarted by the next change in signal. The number of changes in the signal edge within the parameterized chatter monitoring time is measured with the following considerations: • During monitoring, the output signal from the chatter monitoring function

follows the input signal • If the signal chatters, the monitoring time is increased to three times its

defined value, a substitution binary signal is processed further, and a fault TTD is generated

The effects on the process image are that the ”KG” bit is immediately reset in the status data block (ZUDB). The effect on time-tagged data is that a fault TTD ”CHAT coming” is generated. In addition, a signal TTD, channel invalid, is generated if the binary signal of the channel is configured as a TTD. The effects on further internal processing are that the substitution binary signal (EBS) is processed further as the sensor signal according to the parameterization. The new monitoring time is three times the old value. DELAY A signal delay can be parameterized using the DELAY parameter. A delay time between 0 to 10 seconds is permissible. As shown in the diagram below, the following conditions apply when using signal delay: The parameterized delay time is restarted with each change in input signal. If the input signal remains stable during the monitoring time, it is made available at the output for chatter monitoring. Signal delay Binary value in PAED Signal delay Signal delay Signal delay Delayed Binary Value in ZUBD


5

TXP CLC Course EBS The EBS parameter is used to define the status of the binary signal in the event of a fault. There are 4 possible choices in the parameter mask: 0,1,2, and 3. 0 for no substitution, 1 for substituting the last valid value, 2 for substituting a logic “0”, 3 for substituting a logic “1”. The default setting is 0. EIU The EIU parameter is used to activate or de-activate the input signal monitoring function. Depending on which sensor type is connected (GT parameter) the following monitoring functions are available: • Short circuit to L+ in the sensor line • Short circuit to ground in the sensor line When the input signals of a Form C (NO & NC) contact are both logic “1” the monitoring function is triggered. Inversely, if the input signals of a Form C contact are both logic “0” the monitoring function is also triggered. In both cases the “KG” output is reset (logic “0”) if the channel is not being simulated. A fault TTD is generated, if configured, for both “channel invalid” and “short circuit to L+”. If the channel is not simulated the substitution value (EBS parameter) is processed further as the sensor signal.

CONV The CONV parameter is only applicable when the BT function block is used in conjunction with a SIM 323 module to provide interrogation voltage for contacts as shown below:

The default setting is low (logic “0”) for no interrogation voltage provided. If no interrogation voltage is provided the outputs are available to be used separately from the inputs. The CONV parameter affects two adjacent channels and is set on the odd (1,3,5,etc.) channel. Hardware Fault The status word data block is deleted if a hardware fault is present and the block is not simulated. The bit ”KG”, channel valid, is reset (with signal TTD if configured). In the case of simulation, the hardware fault has no effect on the SIM BT function block.

TXP CLC Course Signal TTD Time-tagged data result as a signal TTD (i.e. exception report) following a change in status of the input signal (whether binary signal of Process Image Input Table or simulation value from the Simulation Data Block) if the parameter TTD is set to “1”.

The following signal TTDs are generated: • Change in input signal • Channel is simulated • Channel is valid/invalid A signal connection to the Operating and Monitoring System (OM) must have a destination ID code defined as YP01 and a destination defined as YP01. The signal will then be connected to the Archive, Alarm Summary and can be connected to individual operator graphics. In addition to selecting a signal to be a TTD, the class of alarm to be generated can also be selected using the AWT parameter. The following event classes are available: E Event (will not show up in ASD, only in archive) A Alarm or trip (notifies operator that something has already tripped) W Warning (notifies operator that immediate action needs to be taken) T Tolerance (a tolerance limit has been exceeded) L Local fault (indicates that a non-critical fault has occurred; i.e. “tank level

high” in the case of automatic tank overflow) M Maintenance and service (indicates that a maintenance or service activity

is necessary) C Change (indicates a change in status of a pre-defined switching; i.e.

“changeover to spare pump”) The direction of the TTD to be generated can also be configured using the REV parameter. With REV set to “0” the TTD will be direct acting, i.e. logic “1” will generate a TTD. With REV set to “1” the TTD action will be inverted, i.e. a TTD will be generated on a logic “0”.

TXP-CLC Course Signal Simulation Irrespective of the input signal present a binary signal can be simulated via the software using the software simulation feature. The effect on the process image is the replacement of the process value with the simulation value. The effect on time-tagged data is the TTD ”Channel simulated” or ”Channel not simulated” being generated, in as far as the TTD has been configured for the binary signal. The effect on internal further processing is that the simulation value is processed further as if it were the process value. There is no indication on the module that signal is being simulated. Fault indications for the point will be inactive during simulation. To simulate a signal, on an open function plan with a binary input signal block, select the “BE/SIG” signal definition (SIGDEF) connection with the left mouse button.

Next use the middle mouse button to select the simulation option, and select the binary value on the pop up window. Click “ok” to enter the value.

8 General Description The processing of analog signals in the TXP AS 620 B system (SIM version) is carried out using an AT function block in conjunction with an ET 200M I/O device (SIM 331). The AT function block and SIM module are used to read and monitor analog signals. The following pre-processing functions are also present: • Monitoring for open circuit • Smoothing of analog signal • Simulation of input signals • Monitoring and limiting analog signal • Modification of input signals • Generation of TTD with change in signal • Output of a substitution analog value in the event of faults • Generation binary signals when exceeding limit values • Linearization to physical units • Indication of signal faults The AT function block establishes the connection between the hardware function plans and the automation processor (AP) logic. It is used to establish an analog signal for use in monitoring and/or process control.


1

TXP CLC Course In normal operation, the AT references the value of the input signal from the Process Image Input Table (PAED), conditions it and writes it into the status data block (ZUDB). The signal must be defined (SIGDEF) on the individual level logic diagram (function plan / YFR) that is identified with the Power Plant Identification Code (KKS) for the equipment. The signal is then available for use in the AP. The SIGDEF and KKS must match the input channel identifier in the parameter mask of the SIM module on the rack level location drawing for the connection to the input point.

This function must be configured with parameter “BAV”. Solenoid Valve Standard Application: • Plug-in Switchgear unit with:

2 contactor relays or 1 contactor relay

• Latching in the control system • Limit switches:

1 NO/NC contact on the contactor or 1 NO/NC contact on the valve

When latching in the control system the command output (ALA or ALE) is not reset after the feed-back message (RME or RMA) arrives. This function is configured. The control command is permanently output by the module (configurable with parameter “BAV” ) in the case of switchgear without latching. In this case, a change in the command output (from “On” to “Off”) only takes place with the counter (opposite) command. The logic functions correspond to those of a motor drive. It is possible to have applications where only one contactor relay is connected to the command output (preferably on (ALE) but can be either on or off).

TXP CLC Course Under-voltage monitoring Fast switch off of motors affected by a bus under-voltage can be achieved with an under-voltage monitoring function (UGS), to prevent charring of the contacts or motor overheating failure. The motor is restarted automatically if the voltage returns within a configurable maximum time (parameter “TUM”). The drive remains switched-off if the power failure lasts longer than the permissible failure time and the message “Under-voltage protective action” is sent to the Operating and Monitoring system Alarm Summary Display. The function also permits staggered start-up of motors when the voltage returns. It is possible to prevent an overload on the bus. The staggered start times can be configured with parameter “TWS” for each drive. TAG-OUT The TAG-OUT function allows the DCM to be made inactive. It is in addition to the plants existing lockout / tag-out procedure and does not replace it. When tag-out is active neither Manual, Automatic nor Protection commands can send outputs to the motor drive. Nevertheless, the feed-back messages of the system are updated and indicated on the OM 650 for the operator. The TAG-OUT function can only be used after adequate configuration of parameters “TOUS” and “RMS”. The switchover and the indication of TAG-OUT are done via the operating window of the OM 650. The TAG-OUT function can only be used when the DCM is in Manual and the motor/solenoid valve is in the OFF/CLOSED position. TAG-OUT ON • Disables “On” and “Off” output. For example, the motor/solenoid valve is

not operable from the OM 650 or from any logic inputs, including protection commands.

• The acquisition and indication of feed-back messages, e.g. “MOTOR ON” is continued independently

TAG-OUT OFF • The DCM operates normally: command processing takes into account the operating modes “Automatic”, “Semi” and “Manual”.

Operating Modes Operating mode is selected based on the parameters “RMS”, “VBAF”, “MAUS”, “REJ/MAN”, “OP_MODE“; the inputs “VOS”, AUTO”, “MAN”; and the operating window buttons of the OM650. The “SEMI” or semiautomatic mode is selected if the parameter “RMS” is set to “TAG OUT NO”. For any other operating mode, the parameter “RMS” should be set to “TAG OUT YES”. The “VBAF” parameter allows a manual or automatic close command even if the DCM block is in an alarm condition. The “REJ/MAN” parameter forces the operating mode to manual if manual mode is allowed and the block is in alarm. The “MAUS” parameter allows a changeover from manual to automatic either from the operating window of the OM650 or from the “AUTO” or “MAN” logical inputs to the DCM block. The “OP_MODE” parameter selects between the three options shown below. Once an operation mode is selected, the DCM block can only operate in the modes named under “Selection”. OP_MODE Selection Automatic

Commands Manual Commands

AUTO/MAN Manual Automatic

SEMI/MAN Manual Semi-automatic

Deactivated Activated

Activated Activated

SEMI Semi-automatic Activated Activated Automatic activated means that automatic commands are effective and manual commands are disabled; Semi means that manual and automatic commands are effective; and Manual means that manual commands are functional and automatic commands are disabled. The switchover and indication of the operating modes “Automatic”, “Semi” or “Manual” is done via the operating window of the OM 650 or in the logic. No distinction between the operating modes “Automatic” and “Manual” can be made if the TAG-OUT function is not activated with the parameter RMS. The “VOS” input (local control) deactivates all manual, automatic or semi-automatic commands and allows the feedback to change with local commands without initiating alarm conditions. The protection commands are still active.

TXP CLC Course Command Generation There are six types of commands: • Forcing commands (ignoring enabling permissives and protection) • Protection commands (protecting equipment or personnel safety) • Commands from a local control unit (at motor or starter) • Automatic commands (logic control with enabling permissive) • Manual commands (operator control with enabling permissive) • Automatic reclosing (after return to normal voltage) Different enabling criteria, i.e. process enable and manual enable, are required before a command becomes effective and depend on the type and priority of the command. With operating mode FORCING, the drive can be operated via the OM650--commands “Manual ON” and “Manual OFF” irrespective of the process enable and protection, and automatic commands are blocked. The diagram below illustrates the priority scheme in the DCM:

Connections to SIM Modules for Drive Control

To perform the drive control functions, one DCM function block is invoked in the AP for each motor or solenoid valve. There are two possibilities of input and output allocation: 1. Direct allocation of the block inputs and outputs to SIM I/O modules. This is made via the rack level parameter masks. 2. Decoupling. The inputs are acquired via binary input blocks and can be connected to the FB163 function block after processing. In the same way, the command output can be done via binary output blocks. Mixed application of decoupling and direct allocation is possible.

TXP CLC Course Configuration in the FUP (Function Plan) Editor The parameters of the DCM function block are generated by the configuring system ES 680. The parameters can be configured via convenient parameterization forms.

TXP CLC Course Group Alarm Acknowledgement (SQ) Allows FB 163 DCM block to acknowledges all active alarms and return to normal condition for the block when the logic input is a binary “1”. Block OM operating (BL/OM) Disables operation from Super ordinate System (OM650) when the input is a binary “1”. Does not allow manual operations including alarm acknowledge, operator required actions, manual on, manual off, changeover operation mode (manual, semiautomatic or automatic) or tag-out. Block alarm protection command (BL/AP) • When this input is a binary “1” an executed protection command does not

need to be acknowledged. A protection command execution with BL/AP causes the following: • Last status reached by protection is set • Feed back message shows actual state (on or off) • Disables the respective counter command A protection command execution without BL/AP causes the following: • NOSD (no status discrepancy or message at protection execution) is reset • Last status reached by protection is set • Feed back message shows actual state (on or off) • Disables the respective counter command • Icon on OM650 flashes red at 2HZ Acknowledgement of “O” class alarm in mini ASD is required by operator Auto command on (A/ON) When this input is a binary “1” and the DCM is in semi or auto operation mode, and the input EN/ON is a binary 1; the output ALE is activated. Auto command off (A/OFF) When this input is a binary “1” and the DCM is in semi or auto operation mode, and the input EN/ON is a binary 1; the output ALA is activated. Under voltage limit signal (UGS) When this input is a binary “1” the maximum under voltage timer TUM is started. Protection command on (P/ON) When this input is a binary “1” the DCM is forced on (ALE on) regardless of state of the enabling inputs Protection command off (P/OFF) When this input is a binary “1” the DCM is forced off (ALA off) regardless of the state of the enabling inputs

Enabling on (EN/ON) When this input is a binary “1” the DCM is enabled to be turned on (ALE) either manually or automatically. Enabling off (EN/OFF) When this input is a binary “1” the DCM is enabled to be turned off (ALA) either manually or automatically. Local controlling (VOS) When this input is a binary “1” the DCM is put into the Local Control mode. The controller then expects operation from a control unit at the switchgear, breaker, starter or motor. Changes in feedback related to local operation will not cause alarm or fault indication. When this input is a binary “0” the DCM will alarm or fault with a change in feedback caused by a local operation. Priority switch over man/auto (AUTO) When this input is a binary “1” the operating mode of the DCM is switched to automatic or semiautomatic similar to using the operator faceplate. Priority switch over auto/man (MAN) When this input is a binary “1” the operating mode of the DCM is switched to manual or semiautomatic similar to using the operator faceplate. Feedback Off (FB/OFF) This binary input can be used to decouple the hardware from the software and allow modification to the input signal by additional logic before the signal is connected to the DCM FB 163. When this input is a binary “1” the DCM receives feedback that the driven device (motor, solenoid, etc.) is in the off or closed position. It can be used in place of the hardwired input RMA. Switchgear Fault (SGF) This binary input can be used to decouple the hardware from the software and allow modification to the input signal by additional logic before the signal is connected to the DCM FB 163. When this input is a binary “1” the DCM receives feedback that the driven device (breaker, switchgear, etc.) is in a fault condition. It can be used in place of the hardwired input SAG. Feedback On (FB/ON) This binary input can be used to decouple the hardware from the software and allow modification to the input signal by additional logic before the signal is connected to the DCM FB 163. When this input is a binary “1” the DCM receives feedback that the driven device (motor, solenoid, etc.) is in the on or opened position. It can be used in place of the hardwired input RME.

Last status reached by protection (ZES) This output is a logic “1” when the last command output was initiated by protection. Last status reached by automatic (ZEA) This output is a logic “1” when the last command output was initiated by automatic. Last status reached by manual (ZEH) This output is a logic “1” when the last command output was initiated by the operator. Under voltage time running (USZ) This output is a logic “1” when the under voltage input (UGS) is a logic “1” and the timer has not timed out. Under voltage limit signal (ULS) This output is a logic “1” when the under voltage input (UGS) is a logic “1” and the timer has timed out. Feeder ready for operation (AZB) This output is a logic “1” when the feeder not ready for operation input (ANB) is a logic “0” and the breaker or switchgear is in test position or racked out. No Status discrepancy (NOSD) This output is a logic “1” when there is no status discrepancy fault. It is a logic “0” when there is a fault condition for the FB 163. A status discrepancy is present if the actual status changes without a corresponding command (actual status ≠ command memory). It is assumed that the new actual position has been signaled by non-faulty feedback messages. No feeder fault (NOFF) This output is a logic “1” when the feeder fault input (SAG or SGF) is a logic “1”.This would indicate a trip condition or over current event in the motor starter.

TXP CLC Course MMI Generator The MMI pictures need to be compiled to allow the connections to be made from the logic diagrams to the graphics. Follow the steps below to accomplish this. From the main ES 680 menu click on generators then OM then MMI as shown below: Ensure that the MMI editor is closed prior to generation:

There are three choices when generating MMI: a) all modified pictures in the project b) All pictures in the project c) one picture only, by entering the display KKS

Select All pictures then click on OK.


TXP CLC Course BDM Generator BDM generation is required to create the text database that will be used for all KKS signal names and descriptions on the OT. Each Alarm Summary Listing, Indication window, operation window or detail window will retrieve information from the BDM text database for display. The information will be taken directly from the YFR logic diagrams (function plans) that have been created for the project.

The BDM resides in the SU component of the OM system. It should be generated and transferred initially then subsequently only after new SIGDEFs are assigned

12

From the main ES 680 menu click on Generators then OM then BDM to start the generation of the text database. Choose All diagrams and click OK to generate the code.

TXP CLC Course Transfer Procedures The AP should be in run mode before a code transfer is attempted. This is indicated by a steady green run light on the master and a flashing green run light on the standby processor. LAN code needs to be downloaded to the new CP. To accomplish this proceed as follows: From the main ES 680 menu click on Transfer then LAN then AP as below:


Type in the desired AP number and a protocol file name (for later perusal), then click on OK. When the process is complete a pop-up window will appear stating that the down load is complete. You will need to acknowledge this message by clicking on the close button in the pop-up window.


TXP CLC Course

To load the compiled program in the CPU proceed as follows: From the main ES 680 menu click on Transfer then Load AP (offline) as below:


Type in the desired AP number. The name of a protocol file (for later perusal) will always be AP_OFFL_TRANS. Then click on OK. The program will first check to see if the code is acceptable for transfer. If the code is ready the program will continue with a transfer of the LAN code to the CP1430. The ES680 will attempt to connect to the AP. An error message at this point will indicate that an AP reset is required and then the transfer will need to be reattempted. Up to three overall reset and general reset combinations may be required before the AP is ready to accept the code, even if the indicating lights on the AP show a running condition. At this point the offline handler will take control of the AP and place it in stop and set all of the outputs to zero. First it will down load code to the master (A) then it will update the slave (B) CPU, if required. When the process is complete a pop-up window will appear stating that the down load is complete. You will need to acknowledge this message by clicking on the close button in the pop-up window.


17

TXP CLC Course To load the compiled MMI graphics to the Operating Terminal (OT) proceed as follows: From the main ES 680 menu click on Transfer then OM then MMI Picture as below: The pictures need to be transferred to every OT in the plant, starting with the leading OT. Each OT must be logged off in order to transfer to it.

Select All Pictures, enter the Leading OT hostname and click on OK to transfer the pictures.

To load the compiled BDM text Database to the Server Unit (SU) proceed as follows: From the main ES 680 menu click on Transfer then BDM as below: It is not necessary to log out of any running program while you transfer BDM. It is necessary to transfer BDM to each running SU separately. Enter the SU hostname and click OK.

TXP CLC Course Generation for online transfer After code has been initially loaded into an AP, subsequent changes can be generated and transferred online, which means changes can be loaded while the AP is running. Care must be taken to ensure that the changes will not have adverse affects on the process. To accomplish this from the main ES 680 window select: Generators then AP then Code generation for transfer.

Enter the AP number. Always enter 0 for the APF number since we do not have. Do not tolerate open signals or source connectors if you plan to transfer the code. Choose to start the online-handler and click on OK to start code generation.


TXP CLC Course If any hardware modifications have been made, the system automatically starts the corresponding incremental generation. This means that it is not necessary to start the hardware generator manually and only changes to the code will be generated and transferred. Selecting to start the online handler is optional. Starting the online handler means the online transfer can be started in the event there are no errors in the generated code. Otherwise the code can be downloaded at a later time. Select Load to start the online handler and transfer the code.

12

If you select Close the generated code will be stored and can be transferred later either offline or online.


21

TXP CLC Course On-line transfer The online transfer will start the Online handler. This will allow the system to update only the code that has been changed. The code transfer will be quicker than an offline transfer. The Online Handler will also allow the code to be transferred while the AP continues to run. The offline transfer shuts down the AP and set all outputs to zero while all of the step 5 software required to support the user code and the user code are transferred. The online transfer will only transfer the user code that has changed since the last transfer. From the main ES 680 window select Transfer then AP then Load AP online.

Enter the AP number and 0 for the APF number and click on OK.

There are some modifications that cannot be transferred online: • PB packaging: adding new diagrams to a loaded PB. It is possible to

delete functions from an existing PB-package, but not add new ones online

• Installation or removal of function blocks, which would cause relocation

into another processing frame. However, shifting function from one time-controlled cycle to another is possible

• Possible, but risking the occurrence of malfunctions, is the downloading of

following modifications:

• Disconnection without reconnecting signals at function modules • Deletion of module channels • Cycle time modifications i.e. changing the running cycle of any

loaded PB

TXP CLC Course Service, commissioning and other support functions When all diagrams have been generated and code has been transferred, the AS is able to carry out the automation functions. The following online options are supported by ES680, which provides: • Dynamic function diagrams, i.e. the analog and binary plant values can be

viewed within a function diagram during online operation. This is an important feature during commissioning and other testing activities since no extensive measurements at wiring elements or using the programming device are required

• Fast parameter change: mask parameterizations of any function can be

loaded into the automation processor online without generating code. By confirming the change the transfer will take place and the changed values can be observed immediately.

• Process values can be simulated and preset by simulating inputs from

transmitters. The TXP system will use the simulated value instead of the actual input and will ignore faulty ones (No hardware simulation is required).

• Analog and binary values can replace the values calculated by the system

at previously fixed locations using simulation functions blocks (simulb and simulk).
