In our automation project we need to link 7 modbus slaves which work only in an RS232 configuration. The modbus master is a GE FANUC plc module that can be configured in either RS232 or RS485 but the slaves are RS232 only. Is it possible to build a multidrop network in RS232 or do we have to build an RS485 network and add an RS485/RS232 coverter for each slave? any other suggestion?
