2. CEA DSM Irfu Projects o SPIRAL 2 project (2008) : Modbus TCP protocol / Siemens PLCs VME & Linux platforms o IFMIF project (2009) : OPC server / Siemens PLCs windows platform o IPHI project (1998)  Source renewal (2011) S7PLC / Siemens PLCs Linux platform - Pierre MATTEI SIS / LDISC -19/07/2013 2

3. CEA DSM Irfu Spiral 2 Achieved with Modbus driver support and Asyn module (Marc Rivers) - Pierre MATTEI SIS / LDISC -19/07/2013 3

4. CEA DSM Irfu Source & LEBT in Grenoble - Pierre MATTEI SIS / LDISC -19/07/2013 4

5. CEA DSM Irfu IFMIF-EVEDA Achieved with the Epics OPC device support (C. Winkler and B. Kuner from BESSY) The OPC server, connected with PLCs, is hosted by an insdustrial PC (Siemens) running microSoft XPE A win32 softIoc with Epics OPC device is also executed on the same platform. Communication between OPC server and Epics OPC client is established using the µsoft DCOM protocol. Process Variables are available on the network with the Epics Channel Access Protocol. - Pierre MATTEI SIS / LDISC -19/07/2013 5

7. CEA DSM Irfu IPHI : Source Renewal The first work was done with S7tcp SLS product (2000) on a VME platform. We are now moving to the S7plc EPICS driver (D. Zimoch/SLS) where the driver and the PLC periodically exchange data over the network using fixed size data block. The source SILHI is now available under S7plc and we have now to renew the whole installation : RFQ and LEBT. - Pierre MATTEI SIS / LDISC -19/07/2013 7

9. CEA DSM Irfu Conclusion We used Modbus/TCP, OPC server and S7PLC to establish the communication between PLCs and Epics applications. Modbus for Siemens PLCs is a « ligth » driver : we don’t have all functions - databases are not easy to design. OPC server is an industrial solution but only runs on windows operating systems. S7PLC seems to be a good solution for Epics platforms : easy to configure and to use. - Pierre MATTEI SIS / LDISC -19/07/2013 9
