Electrostatically Sensitive Devices

! ImportantHandling of electrostatically sensitive devices (ESD) When handling electrostatically sensitive components make sure the

operator, workplace and packing material are properly earthed.

Generally, electrostatically sensitive components must not be touched unless work has to be carried out on them. Always handle printed circuitboards without touching pins or printed conductors.

Touch components of the equipment only if

you are permanently earthed by means of an antistatic chain

you are wearing ESD boots or ESD boots with earthing strips inconjunction with an ESD flooring.

Modules may be set down only on electrically conducting surfaces (tablewith ESD top, conductive ESD foam plastic, ESD packing bags, ESD trans-port containers).

Keep modules away from visual display units, monitors, or TV sets (mini-mum distance from screen > 10 cm).

Modules must not be allowed to come into contact with electricallyinsulating materials such as plastic film, insulating table tops or clothingmade of synthetic fibers.

Measurements on modules are allowed only if

the measuring instrument is properly earthed (e.g. equipment groundingconductor) or

before measuring with a potential-free instrument, the probe is brieflydischarged (e.g. touch the bare, earthed metal control housing).

The SINUMERIK FM-NC may be used only for the applications provided for inthe Installation and Start-Up Guide and only in conjunction with non-Siemensequipment and components recommended or authorized by Siemens.

Particular attention is to be paid to the following:

Cable installationTo avoid electrical interference, power and signal cables must not be laid inthe same cable duct. A check must be made to ensure that all cables areproperly installed/routed and correctly connected to the actual value sensors(measuring system) and to the drives (setpoint).Any cables assembled by the customer must be checked for adequate qual-ity/workmanship, particularly the shield cabling.

Earthing system checkTo ensure fault-free operation of the system, it is essential that any externalinterference is diverted effectively. The earthing system must comply withthe specifications laid down in the SINUMERIK FMNC Planning Guide. Inthis respect, it is particularly important that: the earthing system complies with requirements stated in DIN VDE 0160, a common earthing system is provided for the NC, drive and machine, the earth connections are taken in a start connection to a central earth-

ing point equipotential bonding is provided between the individual components a PE connection is provided and relays and motors are equipped with interference suppression elements.

Power supply checkA check must be made to ensure that the power supply cable connectionsfor all S7300 system function modules and the power supply tolerancerange are correct.

In order to start up the system, the basic data (velocities, timers, names, etc.)and information which were produced in the course of design and configurationof the installation must be made available. These data cover all areas of thecontrol system.The data required to start up basic functions are listed below.

Overview

2.1 Integration of FM-NC module (NCU 570.2) in the S7-300 PLC

207.2000


The NCU 570.2 constitutes the NC area.The NCU 570.2 communicates

with the SIMATIC S7-300 CPU via the serial P (peripherals) and C (commu-nications) buses,

with the FM 354 (as axis extension) or with digital input/output modules viathe serial local P bus,

with up to four servo drives via a 10 V interface and/or with up to four step-per drives via pulse interfaces,

with incremental or absolute measuring systems via four measuring circuitinterfaces and

with operator panels (OP), programming devices (PG) and machine controlpanels (MCP), etc. of various rating classes via the multi-point serial inter-face (MPI).

The following can be connected via a 20-pin front connector with single-wireterminals:

2 probes 4 sensing elements, e.g. proximity sensors 2 handwheels.

The NC area can be extended if required by installing an FM 354 which is con-trolled by the NCU 570.2 via a local bus. Furthermore, additional NC-specificinputs and outputs can be implemented through the installation of additionalsignal modules (without exceeding the maximum configuration per tier) whichare driven via the local P bus.

The FM 354 communicates as an axis extension module

with the NCU 570.2 via a serial local P bus,

with the SIMATIC S7-300 CPU during power-up via the serial local P bus,

with a servo drive via a 10 V interface and

with an incremental or absolute measuring system via a measuring circuitinterface.

The following can be connected via a 20-pin front connector with single-wireterminals:

4 digital inputs 4 digital outputs

Since the FM-NC is an integral component of the S7-300 installation, with thePLC-CPU acting as the master, the entire S7-300 system must be started upfirst.

To start up the entire S7-300 system, please refer to the following documenta-tion:References: /S7H/, SIMATIC S7-300 manual

2.3 Power supply

2.3.1 Power supply requirements of entire S7-300 system

The S7-300-CPU can buffer mains supply interruptions lasting up to 5 ms (guaranteed minimum period).After a power failure, a back-up period of at least 50 ms is still available in theNCU 570.2.

Note

In order to bridge power supply interruptions of > 5 ms, the FM-NC, FM 354and PLC-CPU (or the entire S7-300 under ideal conditions) should be operatedon a common 24 V power supply which guarantees the power supply back-uptime required by the customer.PS 307 power supply modules (2 A, 5 A and 10 A) should preferably be used,depending on power requirements. These modules are capable of bufferingsupply failures of 20 ms.

If the customer prefers to use a separate power supply for the FM-NC, FM 354and PLC CPU 314 as an alternative to the above solution, then he must ensurethat all modules are powered up/down simultaneously when POWER OFF/ONis selected. The FM-NC cannot be powered up via POWER OFF/ON sepa-rately from the PLC CPU 314.

2.3.2 FM-NC power supply

4-way screw-type terminal blockTerminals 1 and 3: L+ +24 V load power supplyTerminals 2 and 4: M 0 V load power supply (frame)

2nd phase: Battery faultThe BAF LED lights up steadily when the battery voltage has dropped belowthe minimum value required to buffer the RAM.

During control power-up, the system automatically branches to the start-upmode with default values and the error message Standard machine dataloaded is set. A new battery must be inserted before buffered data are reloadedor entered again.If buffered data have been lost, please proceed as described in Section 11 or 3.

Battery type: Li battery set with connecting lead,size 1/2 AA, capacity approx. 850 mAh,voltage min. 3.6 V

3.1 MPI networking rules

The following basic rules must be observed with respect to networkinstallations:

1. The bus line must be terminated at both ends. To do so, switch in theterminating resistor in the MPI connector in the first and last nodes. Switchout all other terminating resistors.

Note

Only two terminating resistors may be activated in the same line at a time.

2. At least one termination must be supplied with a 5V voltage. For this pur-pose, the MPI connector with active terminating resistor must be connectedto a device that is connected to the power supply.

Note

Connecting the MPI connector to the PLC (CPU) is ideal for this purpose.

3. Spur lines (feeder cable from bus segment to node) should be as short aspossible.

Note

Unused spurs should be removed wherever possible.

3.2 Standard configuration

PLCCPU mit SINUMERIK FM-NC, MMC and a machine control panel (MCP)or interface to customer operator panel on MPI bus.

The following hardware components are required for the minimum configuration

AS300 PLC-CPU (315, 316, 614, .., 318) SINUMERIK FM-NC NCU 570.2 with firmware version from V 03.xx

MMC

MCP or interface to customer operator panel.

STEP7

MPI bus nodes operate at 187.5 kbaud.

Every node on the MPI bus must have a bus address (0...31).Fig. 3-2 shows the default settings for the MPI bus addresses.

The addresses of the bus nodes can be set as follows:

MMC 100/100.2

Default address: 1

Setting in configuration file NETNAMES.INI using application softwareReferences: /FB/, B3, Several Operator Panels and NCUs

MMC 102/103

Default address: 1

Setting in operating area Startup/MMC/Operator panel

Programming deviceDefault address: 0

Setting in STEP7 via menu Extras / PG/PC interface

PLC-CPU

Default address: 2

Setting in STEP7 hardware configuration under menu item Edit/Objectproperties/General/Properties/MPIAfter changing the MPI address, it is necessary to load the configuration intothe target module via menu item Target system/Load into module. It isonly possible to change the MPI address if the PLC-CPU is in STOP.References: /S7H/, S7 Manual or

/S7HT/, Start-up MPI Bus Nodes manual

FM-NC (NCU 570.2)Default address: 3

Setting: The PLC-CPU ascertains the MPI bus address of the FM-NCfor its rack configuration while the S7-300 system is being booted. This slot-dependent MPI address is then transferred to the C-bus modules. Based onits own MPI address, the PLC-CPU increments by one the MPI address foreach C-bus moduleExample:

! ImportantIt must be ensured that the addresses of other MPI nodes (e.g. MCP = 6) arenot overlapped when the addresses are consecutively numbered in this way.

The following bytes in the PLC-CPU are assigned for the MCP or interface tocustomer operator panel (applies when SDB210 of the basic program Library isused): Input bytes 118...125

Output bytes 120...127

Status bytes for error detection, output double word 108 (evaluated by basicprogram)

These parameters on FB1 in OB100 (basic program) for the MCP are alreadyset.

Note

The input and output bytes given above are addresses in the range of the 4thrack. If this address range in the 4th rack is being used, different input, outputand status ranges must be assigned in the PLC-CPU and a new SDB210 mustbe generated (see Section 3.3).

If communication does not commence after a PLC reset (all display LEDs of theMCP flashing), the following points should be checked: Cable and connector wiring

3.3 Nonstandard configuration

To name an example, the connection of additional MPI bus nodes would consti-tute a nonstandard configuration. The following are nonstandard features:

Connection of a hand-held unit (HHU)References: /BH/, Operator Components manual

Connection of a second MCP

Connection of further PLCs

Nonstandard settings with regard to the HHU, MCP and PLC are specified inthe global data configuration (see Section 3.4 ).

Connection of an OP 27 operator panel

(Configuration via ProTool.)References: /ST7/, Catalog ST 70

Connection of further FM-NCs

(Configuration via the PLC basic program on FB1 in OB100.) Connection of positioning modules FM 353/FM 354 (not on local

P bus of the FM-NC)(Configuration via the startup tool.)References: /S7S/, /S7L/, SIMATIC S7-300 manuals

You must adjust the communications parameters and possibly the switch set-tings (addresses) of the bus nodes.

To be able to enter a new configuration it is necessary to define global data inSTEP7. Select the object MPI network in the STEP7 project and then selectDefine global data in the menu Extras. The following procedure assumes thatthe user is acquainted with the handling of this tool.1. Set up a new project in STEP7. A separate station is to be set up for each of

the components (PLC, HHU, ...) which are linked together via MPI.2. Link the MPI nodes, i.e. interconnect CPU programs with MPI address

(hardware configuration).3. Define global data and enter the desired configuration4. Compile this configuration. A new SDB210 (system data block) will be crea-

ted for each CPU program. The SDB210 for the component MCP/HHU ismeaningless, because the settings of the basic data parameters are madewith DIP switches or via the keyboard.

5. Set the cyclical transmit pattern. Once the configuration has been compiledsuccessfully for the first time, the Conversion factor (SR) and Status(GDS) can be activated and then input.

6. Compile your configuration again.7. Transfer the SDB210 (from the CPU program of the PLC) to the PLC.

Note

The SDBs are not displayed in the STEP7 project manager by default. Theyare listed by double-clicking on the object System data.

8. Make the device-specific settings for all nodes: You now need to set the GDidentifiers from the table of global data definitions for the components(HHU,..).

9. You must set the input, output and status parameters for call FB1, DB7 inOB 100 in the basic PLC program for all operator control components (MCP,HHU).
