communication plc bud should rs 485 ?? will the modbass work with rs 232 or rs422???

@@jone2409 MODBUS is a protocol so electrical standard does not matter that much. It will work with RS422 but the program needs to support it.

@@FactonationTH plc fx if there are no additional RS modules, can you change the settings of the standard RS PIN8 protocol? I did not find. Thank you very much

@@jone2409I think you cannot do that. You need to purchase additional extensions module from Mitsubishi to get that capability. I would suggest you look into other brands/alternatives like Samkoon or Amsamotion PLC.
