Data Line: The Profibus user group recommends the following color coding for the data signal lines:

A-Data Line = Green B-Data Line = Red

These data signal lines must be connected to the corresponding signal terminals or pins at the master unitand other stations (i.e.A to A, B to B).

RTS: The signal RTS (TTL signal relative to Data Ground) is meant for the direction control of repeaters incase repeaters without self control capability are used.

+5V DC, Data Ground: The signals +5V DC and Data Ground are meant to power an externally mountedbus terminator.

The powering of the 220 © termination resistor ensures a defined idle state potential on the data lines. Toensure proper functioning up to the highest baud rate, each bus segment has to be terminated at both endsof the cable.

3.1 Introduction to Profibus

For more details on Profibus, please refer chapter 5

3.2 PXP-3148PB Operations

PXP3148-PB allows ATV31/ATS48 to communicate on Profibus DP network as Profibus DP Slave. At the same time itallows remote keypad to communicate with ATV31/ATS48. Power required for remote keypad is also available on remotekeypad port,

Upon Power-Up PXP3148-PB does not have the ATV31/ATS48 Modbus station address and also does not have Profibusslave address in order to communicate on Profibus network. So, it starts scanning node connected on controller port. Forthis PXP3148-PB send Modbus read request for Modbus reference 400001 starting from station address 01 up to 125.ATV31/ATS48 connected on controller port responds when it receive query with its own station address.Normally, PXP3148-PB requires less than 15 seconds to discover the node connected on its controller port. Time requireto discover the node is less if Modbus station address is small (e.g. 01,02,03 etc.). Time require to discover the node ismore (maximum 15 seconds) if Modbus station address is big (e.g. 125). Once ATV31/ATS48 is discovered by PXP3148-PB, Modbus station address of ATV31/ATS48 is assigned as profibus slave station address.

Once Profibus station address is acquired, PXP3148-PB checks for configuration properties of ATS48 (If ATV31 isconnected, it directly enters in data exchange mode). If configuration properties are present, these configurationproperties are transferred to ATS48 and then it enters in data exchange mode. For more information on configurationproperties, please refer section (3.2.1).

During data exchange, if communication break occurs due to power to ATV31/ATS48 is removed, communication cablefault etc. Then this error is reported to profibus master (for details see section 4.2)

Both the Profibus master requests and Remote keypad requests are serviced by PXP3148-PB on time-sharing basis.

PX3148-PB has two areas for profibus communication namely, Input area and Output area. Profibus master access thesetwo areas for exchanging data. The term Input and Output are referred with respect to Profibus Master. Input is an inputto Profibus Master and output is an output from Profibus Master.PXP-3148PB fetches data from ATV31/ATS48 and writes this data to Input area. Further, profibus master reads this datafrom input area. Profibus master writes data in Output area and PXP-3148PB transfers this data to ATV31/ATS48.

Size of Input area is 100 words and reference is given to each word for simplicity. For example 1st word of input area isreferred as I000, 2nd word of input area is referred as I001 and so on.Size of output area is 100 words and reference is given to each word for simplicity. For example 1st word of output area isreferred as O000, 2nd word of output area is referred as O001 and so on.

If configuration properties are never written in ATS48, PXP-3148PB waits for configuration properties before actual dataexchange. Once the configuration properties are written in PXP-3148PB, it starts data exchange.

3.2.1 Writing configuration properties

Configuration properties are application specific and written to ATS48 only once after power on. Configuration propertiesare stored in flash memory of PXP-3148PB. On power up, PXP-3148PB read these configuration properties from flashmemory and transfer to ATS48. Even though ATS48 in a field is replaced by new ATS48 or another ATS48, user need nothave to write configuration properties again as they are already present in internal flash memory of PXP-3148PB. Insuch a cases user have to power cycle PXP-3148PB once.

For writing configuration properties,User should write (0x0000) to O000.Then user should write application specific values in O001 to O016 (as described in parameter table) using ProfibusMaster.Then user should write (0x0001) to O000.

PROFIBUS



PROFIBUS is a vendor-independent, open fieldbus standard for a wide range of applications in manufacturing, processand building automation. Vendor independence and openness are guaranteed by the PROFIBUS standard EN 50170. WithPROFIBUS, devices of different manufacturers can communicate without special interface adjustments.The PROFIBUSfamily consists of three compatible versions:

High speed PROFIBUS-DPDP stands for Decentralised Periphery. It is optimised for high speed and low cost interfacing,especially designed for communication between automation control systems and distributed I/Oat the device level.

Process Automation PROFIBUS-PAPA stands for Process Automation. It permits sensors and actuators to be connected on onecommon bus line even in intrinsically-safe areas. It permits data communication and powersupply over the bus using 2-wire technology according the international standard IEC 1158-2.

Higher level PROFIBUS-FMSFMS stands for Fieldbus Message Specification. This version is the general purpose solution forcommunication tasks at a higher level. Powerful services open up a wide range of applicationsand provide great flexibility. It can also be used for extensive and complex communications tasks.

Uniform bus access PROFIBUS-DP and PROFIBUS-FMS use the same transmission technology and a uniform busprotocol access protocol. Thus, both versions can be operated simultaneously on the same cable.

However, FMS field devices cannot be controlled by DP masters or vice versa.

Note: It is not possible to exchange one of these family members by another familymember. This will cause faulty operation.

The rest of this section only describes PROFIBUS-DP.Protocol architecture.

5.2 Introduction To Profibus

PROFIBUS




Layer 1, 2 and user PROFIBUS-DP uses layers 1 and 2, and the user interface. Layers 3 to 7 are notinterface defined. This streamlined architecture ensures fast and efficient data transmission. The

application functions which are available to the user, as well as the system and devicebehaviour of the various PROFIBUS-DP device types, are specified in the user interface.

Transmission medium RS-485 transmission technology or fibre optics are available for transmission. RS-485transmission is the most frequently used transmission technology. Its application areaincludes all areas in which high transmission speed and simple inexpensive installation

High-speed, inexpensive are required. Twisted pair shielded copper cable with one conductor pair is used.

Easy installation The RS-485 transmission technology is very easy to handle. Installation of the twistedpair cable does not require expert knowledge. The bus structure permits addition andremoval of stations or step-by-step commissioning of the system without influencing theother stations. Later expansions have no effect on stations which are already in operation. Transmission speeds between 9.6 kbit/s and 12 Mbit/s can be selected. Oneunique transmission speed is selected for all devices on the bus when the system iscommissioned.

Cable length The maximum cable length depends on the transmission speed The specified cablelengths are based on type-A cable. The length can be increased by the use of repeaters.The use of more than 3 repeaters in series is not recommended.

5.1.2 Device Types

PROFIBUS distinguishes between master devices and slave devices.

Master devices Master devices determine the data communication on the bus. A master can sendmessages without an external request, as long as it holds the bus access right (thetoken). Masters are also called active stations in the PROFIBUS standard.

DPM1, DPM2 There are two types of master devices: DP master class1 (DPM1) and DP master class2(DPM2). A DPM1 is a central controller which exchanges information with thedecentralised stations (i.e. DP slaves) within a specified message cycle. DPM2 devicesare programmers, configuration devices or operator panels. They are used during commissioning, for configuration of the DP system, or for operation and monitoring purposes.

Slave devices Slave devices are peripheral devices. Typical slave devices include input/output devices,valves, drives, and measuring transmitters. They do not have bus access rights and theycan only acknowledge received messages or send messages to the master whenrequested to do so. Slaves are also called passive stations.

22


PROFIBUS



5.1.3 PROFIBUS-DP Charactristics

5.1.3.1 Bus Access Protocol

Layer 2 The bus access protocol is implemented by layer 2. This protocol also includes datasecurity and the handling of the transmission protocols and messages.

Medium Access Control The Medium Access Control (MAC) specifies the procedures which determinewhen a station is permitted to transmit data. A token passing procedure is used tohandle the bus access between master devices, and a polling procedure is used tohandle the communication between a master device and its assigned slave device(s).

Token passing The token passing procedure guarantees that the bus access right (the token) isassigned to each master within a precisely defined time frame. The token message, aspecial message for passing access rights from one master to the next master, mustbe passed around the logical token ring - once to each master - within a specified targetrotation time. Each master executes this procedure automatically. A user can onlychange the target rotation time, but is not recommended.

Polling procedure The polling or master-slave procedure permits the master, which currently owns thetoken, to access its assigned slaves. The picture below shows a possible configurationThe configuration shows three active stations (masters) and six passive stations(slaves).

The three masters form a logical token ring. When an active station receives the tokenmessage, it can perform its master role for a certain period of time. During this time itcan communicate with all assigned slave stations in a master- slave communicationrelationship, and a DPM2 master can take the initiative to communicate with DPM1master stations in a master-master communication relationship.

Multi-peer communication In addition to logical peer-to-peer data transmission, PROFIBUS-DP provides multi-peercommunication (broadcast and multicast).Broadcast communication : An active station sends an unacknowledged message to

all other stations (masters and slaves).Multicast communication : An active station sends an unacknowledged message to a

predetermined group of stations (masters and slaves).

23

PROFIBUS




5.1.3.2 Data Throughput

Transmission time At 12 Mbit/s, PROFIBUS-DP requires only about 1 ms for the transmission of512 bits of input data and 512 bits of output data distributed over 32 stations.The figure below shows the typical PROFIBUS-DP transmission time dependingon the number of stations and the transmission speed. The data throughputwill decrease when more than one master is used.

5.1.3.3 Diagnostic Functions

Extensive diagnostics The extensive diagnostic functions of PROFIBUS-DP enable fast location of faultsThe diagnostic messages are transmitted over the bus and collected at themaster. These messages are divided into three levels:

Device related diagnostics 1. Device related diagnosticsThese messages concern the general operational status of the whole device(e.g. overtemperature or low voltage).

Module related 2. Module related diagnosticsdiagnostics These messages indicate that a fault is present in a specific I/O range (e.g. an

8-bit output module) of a station.

Channel related 3. Channel related diagnosticsThese messages indicate an error at an individual input or output (e.g. shortcircuit on output 5).

5.1.3.4 Protection Mechanism

Time monitoring PROFIBUS-DP provides effective protection functions against parameterisationerrors or failure of the transmission equipment. Time monitoring is providedat the DP master and at the DP slaves. The monitoring interval is specifiedduring the configuration.

At the master 1. Protection mechanism at the master.The DPM1 master monitors data transmission of its active slaves with theData_Control_Timer. A separate control timer is used for each slave. This timerexpires when correct data transmission does not occur within the monitoringinterval.If the master’s Auto_Clear mode is enabled, the DPM1 exits the ’Operate’state, switches the outputs of all assigned slaves to fail-safe status, andchanges to its ’Clear’ state.

24


PROFIBUS



At the slave 1. Protection mechanisms at the slave.The slave uses the watchdog control to detect failures of the master or the transmissionline. If no data communication with the master occurs within the watchdog controlinterval, the slave automatically switches its outputs to the fail-safe status. Thismechanism can be enabled or disabled for each individual slave.Also, access protection is available for the inputs and outputs of the DP slaves operating in multi-master systems. This ensures that direct access can only be performed bythe authorised master. For other masters, the slaves offer an image of their inputs andoutputs, which can be read by any master, even without access rights.

5.1.3.5 Network States

PROFIBUS-DP distinguishes four different network states.

Off-line 1. Off-lineCommunication between all DP participants is stopped.

Stop 2. StopCommunication between DPM1 and DP slaves is stopped. Only communicationbetween DPM1 and DPM2 is possible.

Clear 3. ClearDPM1 master attempts to set parameters, check the configuration, and subsequentlyperform data exchange with its associated DP-slaves. The data exchange comprisesreading the inputs of the DP-slaves and writing zero’s to the outputs of the DP-slaves.

Operate 4. OperateDPM1 master exchanges data with its assigned slaves, inputs are read and outputs arewritten. Beside this, the DPM1 cyclically sends its local status to all assigned DPslaves (with a multicast message) at a configurable time interval.

Auto_Clear When an error occurs during the data transfer phase of the DPM1, the ‘Auto_Clear’configuration setting determines the subsequent actions. If this parameter is set tofalse, the DPM1 remains in the ‘Operate’ state. If set to true, the DPM1 switches theoutputs of all assigned DP slaves to the fail-safe state and the network state changes tothe ‘Clear’ state.

25

PROFIBUS




5.1.4 Device Data Base Files

GSD-file To achieve straightforward configuration of a PROFIBUS-DP network, the characteristicfeatures of a device are specified in a file. This file is called a GSD-file(Gerätestammdaten file). The language of the GSD file is expressed with the last letterfrom the extension, *.GS?:

Default : = GSDEnglish : = GSEDeutsch : = GSGItalian : = GSIPortugees : = GSPSpanish : = GSS

The GSD files are prepared individually by the vendor for each type of device, accordingto a fixed format. Some parameters are mandatory, some have a default value andsome are optional. The device data base file is divided into three parts:

General section 1. General specificationsThis section contains the vendor name, the device name, hardware- and softwarerelease versions, station type and identification number, protocol specificationand supported baud rates.

DP-master section 2. DP master-related specificationsThis section contains all parameters which only apply to DP master devices(e.g. maximum memory size for the master parameter set, maximum numberof entries in the list of active stations, or the maximum number of slaves themaster can handle).

DP-slave section 3. DP slave-related specificationsThis section contains all specification related to slaves (e.g. minimum timebetween two slave poll cycles, specification of the inputs and outputs, andconsistency of the I/O data).

Configurator The device data base file of each device is loaded in the configurator anddownloaded to the master device. Refer to the Operation Manual of thePROFIBUS-DP Master Unit for usage of the GSD file in the master’sconfiguration software.GSD files are usually supplied with each unit. Alternatively, GSD files can bedownloaded from the Internet, either from the manufacturer’s site, or from theGSD library of the PROFIBUS Nutzerorganisation at http://www.profibus.com.

5.1.5 Profiles

Exchanging devices To enable the exchange of devices from different vendors, the user data hasto have the same format. The PROFIBUS-DP protocol does not define theformat of user data, it is only responsible for the transmission of this data. Theformat of user data may be defined in so called profiles. Profiles can reduceengineering costs since the meaning of application-related parameters isspecified precisely. Profiles have been defined for specific areas like drivetechnology, encoders, and for sensors / actuators.
