Hello, I have a similar problem, I have a PLC V350-J-TR20, the Visilogic version is 9.8.79 Build 0 Beta,
I have the RS232 physical connection with the MJ10-22-CS25 cable, the PLC already has a program loaded,
the last program has a modbus configuration that is possibly causing me the error, what do you recommend doing?
Thank you
