Profibus communication problem between Beckhoff IPC and Siemens PLC
Hi everybody,
An IPC connected to a Siemens PLC as a slave module. When I restart the PLC while IPC running then PLC can't find the IPC hardware on the Profibus network. I should also explain that if before restarting I disable the IPC node in PLC by using the SFC12 and then restart the PLC and then enable the IPC Profibus node again the PLC can find the IPC easily.
For more information the IPC Profibus node exists as a last module of the bus and some ET200 modules also exist on the bus.
I use Beckhoff IPC with Beckhoff Profibus cards and TwinCAT I/O software for communication to a S7 315 2DP PLC.
Many thanks in advance for your help.

Hi everybody,
I use IPC with Beckhoff Profibus cards and TwinCAT I/O software for communication to a simatic et200m module.
TWINCAT system manager to config et200m show Config wrong message, what should I do with et200m before config in TWINCAT system manager.
Many thanks in advance for your help.

We download new GSD of Siemens et200m and set FC3101, Beckhoff Profibus cards, baud rate at 1.5 M and then communication is well now. Thanks.
