1. System Overview

1.1 System-Description The PROFIBUS protocol, according to DIN 19245 part 1 and 2, is an inter-operable andopen Bus-System. The PROFIBUS master device can be either a PLC or PC. Manydifferent versions of these products are available from a wide variety of manufacturers.

Additionally, subset systems with the PROFIBUS protocol according to DIN 19245 arealso available. These subset systems can be from independent manufacturers orproprietary from a specific manufacturer.e.g.

Independent from a manufacturer:PROFIBUS-DP

Specific manufacturer:Siemens company: SINEC L2-DP

SINEC L2-FMSSINEC L2-TFSINEC L2 cyclical periphery

It is possible to control up to 32 active or passive nodes (122 nodes withmax. 3 repeater).

The PROFIBUS protocol allows for different transmission speeds dependingupon the bus length.

The data medium should be a shielded, twisted pair cable.

1.2 SI-unit IN313-PR1 The Serial Interface (SI) unit IN313-PR1 is a slave device for use with thePROFIBUS protocol. It is possible to connect and control up to 16 valves(16 single- or 8 double solenoid) from the SI unit.

The SI valve manifold systems manufactured by SMC have internally prewired solenoid connections. It is only necessary to make the communicationand power wire connections to the SI unit interface terminal block.It is necessary to set the address and the appropriate transmission protocolwith the DIP switches.

It is not necessary to set the transmission speed because the SI- unitselects the correct transmission speed automatically. When the additionalindex 51 is programmed, the valves switch to a pre-defined position in theevent of a bus error.

6. Wiring / Installation

6. Wiring / Installation All wiring and installation steps should be performed with the power supply off.

For the installation of the PROFIBUS protocol unit it is necessary to take care of theEuropean standards. Example: EN60204 part 1.

Remove the IN313-PR1 unit by loosening its 4 mounting screws and pulling it straightout to disconnect the interface plug. Be careful not to drop the unit or to damage theinterface plug.

6.1 Terminal Block Remove the plastic cover ("spacer A") to expose the screw terminals.

7. Information for Programming

7.1 PROFIBUS Layer-7 Output data is transmitted to index 50 via a write request. Output data canAccess (FMS) be retransmitted using a read request.

Apart from the object index 50 for output data there is a second object index 51 -whichenables the user to predetermine a certain default configuration for the valve terminalshould a connection error occur.

The time interval for the connection verification is stored in object index 49 (Unsigned16). By entering 0, the connection verification is switched off. The unit of the time intervalto be stored is 10 msec. Thus, if the value 1000 is written to index 49, the slave checksevery 10 seconds to see if the Master has an index 51 connection error. If the masterdoes not have writing access during the defined interval, the default configuration onindex 51 is then transmitted to the valves. The connection verification can be deactivatedafter the module has been turned on (object 49 receives 0).

After activation, the PROFIBUS protocol works with the default bus parameters definedin the PROFIBUS-profile sensor technology/actuator technology. The objects index 40and index 41 are used to optimize these bus parameters; data can be read from themand written to them by the master.

Most of the following data is stored on the EPROM and must be manually set toconfigure the PROFIBUS-network.

7.1.1 Bus Parameters: Default values are used as defined in the PROFIBUS-profile sensortechnology/actuator technology.

The two parameters min-TSDR and TSL may be set as write requests via thePROFIBUS.

ATTENTION!!! Time intervals must not be shorter than those defined for the master,otherwise interruption of the communication may occur!!

The interval TSL must not be too short; processing of the access routinemust still be possible.

The limit values of the bus parameter TSDR and TSL depend on the pre-setbaud rate:* 9,6 kBd: 1- 472 Bit* 19,2 kBd: 1- 945 Bit* 93,75 kBd: 1- 6143 Bit* 187,5 kBd: 1- 12287 Bit* 500 kBd: 1- 24575 Bit

Limit values are not checked by the CPU. They must be correctly selected by the user.

7.2.2 Operating on SINEC L2: Via SINEC L2 access the objects may be accessed by SINEC L2 telegrams. For this purpose, a SINEC L2 telegram must use a specifically implemented service access point (SAP).

Local SAP Type of Connection Use5 SINEC L2 Access Read / Write

The connection type SINEC L2 makes access to SIMATIC S5 possible via data transmission by direct access to layer-2 services. Programming of the S5 communication processor is explained in the CP 5430 Manual. (chapter10). The blocks to be transmitted consist of data and a header. Transmission between S5 and

CP 5430 is carried out via handling modules; data is stored on data modulesand can be written to them or read from them by the STEP 5 program.

7.2.3 Operation on SINEC L2- Access to objects via SINEC L2 telegrams is established by connectingCyclic Peripherals: type L2-cyclic peripherals. For this purpose, a specifically implemented

service access point (SAP) must be used for different objects.

Local SAP Type of Connection Use6 SINEC L2 Read / Write7 SINEC L2 Cyclic Peripherals Index 42 Read / Write8 SINEC L2 Cyclic Peripherals Index Read / Write9 SINEC( L2 Cyclic Peripherals Index 51 Read / Write

By means of the connection type SINEC L2-cyclic peripherals and a correspondingprogramming of the CP 5430 (see Manual, chap. 9) PROFIBUS station data can directlybe written and read from the outputs. The peripheral byte that is used for writing and - ifapplicable - reading must be reserved for cyclic peripherals (CP) by the COM 5430software as either output area or output and input area. To avoid overlapping, eachparticipant must be assigned an individual byte. Transmitted and received data can beedited by means of the reserved input or output byte with STEP 5 commands.

7.3 PROFIBUS-DP (SINEC L2-DP)

The SI unit was conceived as passive node (slave) in the L2-DP. The station address canbe selected from 3 ... 124; (hexadecimal 3h ... 7Ch).

The master sends command data to a 4-byte data field that is transmitted in one messageto the valve manifold. To check the transmission, this data package is re-transmitted to themaster in the same cycle.

Diagnostic is not supported, since the valve manifold is not capable of detecting valveerrors.

7.3.1 Use SAPS: The following SAPs are used if the SINEC Q2 protocol is used:

Use SAPSINEC L2 DP (Read Configuration) 59SINEC L2 DP (Read Diagnosis) 60SINEC L2 DP (Write Parameters) 161SINEC L2 DP (Write Configuration) 62SINEC L2 DP (Read/Write Data) NIL

7.3.2 Occupancy of Pin The following pin connection codes are used, individual bytes are given in the table:Connections:

Connection Code Use AccessNo.0 009 Valves 0 ..7 Read1 009 Valves 8 ...15 Read2 009 Valve Data for Error 0 7 Read3 009 Valve Data for Error 8...15 Read4 017 Valve 0 ...7 Write5 017 Valve 8 ...15 Write6 017 Valve Data for Error 0 ...7 Write7 017 Valve Data for Error 8 ...15 Write

These pin connection configuration codes must be entered in the same order by the userduring programming with a PC and COM ET200.

Programming of the valve station follows the same programming technique of the Siemensunit ET200 V.

The initialization of the valve station with the initialization software COM ET200 is the sameas the initialization of the Siemens unit ET200 V. Station type: ET200 U.

All other commissioning operations must be carried out according to L2 DP Masterdocuments (e.g. SIEMENS Dezentrales Peripheriesystem ET200 Handbuch Kapitel9/inbetriebnahme und Test).
