|
We have FlexLogix 5434 connected to ABB PLC (Modbus) through the RS232. We tried to connect to this old AB but when i tried to configure the PLC in the RSlinks the connection is failed to be established!! I used the same way and tried to connect to a new PLC and I succeeded. I tried to ways I used direct serial cable and I used USB to Serial and both did not solve the problem while I managed to connect when i connected to the new PLC unconfigured PLC!!.
I also tried in the redundant PLC and I ended with the same results? I am not sure if I have to define the station number as well?
