Hi Joerg,
We are here using PROFINET with MRP (Media Redundancy Protocol)
ring to connect Siemens S7-1500 PLCs with multiple ET200S
(distributed Inputs/outputs) for the SPIRAL2/DESIR beamlines and
setup developments.
These PLCs are used for Vacuum, Interlocks, Insertion devices
(FCup, BPM), Slits Motorization, ...
This MRP ring with Profinet protocol is a "field bus" only used
for the PLC : The PLC CPU manage itself this MRP Ring.
It is completely EPICS independent and uses the two Ethernet
CPU Ports.
An additional Communication module (CM1542-1) is used with
S7-1500 to allow the Ethernet Network connection of each PLC
with EPICS IOCs (using MODBUS-TCP) and HMI on Touch-Pannel
located closed to the PLC.
Kind Regards,
Laurent.
