In our PLC configuration (Modicon 984-785 E Hot Standby)
We use two Modbus / RS232 port to each PLC CPU=20
to connect with Foxboro INT30 FT.
It means that we must connect each port of Integrator to two ports=20
of each PLC - one port to PLC A and the other one to PLC B.
We try to do this type of connection using three Modems for each line,
communication is OK but we lost a diagnostic of cable problem -=20
when we disconnect one port from PLC side (while the other port of the =
PLC is
still connected)
Can any one advise type of Modem , switch configuration, ect,
so we shell have full diagnostic.
Thanks,
Zvi Pinchasovitch
