Ref542plus => Modbus board
HI,
Sorry for bothering you guys with this question.
We are trying to connect a Protection relay of type "REF542PLUS" HW version V4F.06b through "Modbus" to our system 800xA V5.0 with CI853A (Modbus coupler).We did create the communication block inside the REF542 and also the 800xA, but i didn't work out!
we need to get the connection to REF542plus right so we can configure the DDEF Table.
the issue is:
=> We can't get the MODBUS SUITE 1.8 or 2.2 to be connected to the REF542PLUS !
We tried different communication settings.
we changed the cable.
we changed the optical link to HMI
Our architect is this way:
PC connected to REF542PLUS through RS232 Cable !
=> is it the right way to do it or not?
Any help will be appreciated.
Best Regards.

Did you check the settings as per this "1MRS755238 Feeder and Transformer Terminals REF 54_, RET 54_ Modbus Communication Protocol " document?
