Kieran B Posted October 18, 2019 Report Share Posted October 18, 2019 Hi there, I have an installation with 2 softstarters that use rs485 modbus and an ethernet gateway that is the master of that ring I can send and receive all data needed using Modscan32 over TCP connection on laptop to both softstarters so far i havent been able to get a response from the softstarter when using the PLC - error code 5 and 4. SO I guess the question is, does the slave ID get sent along with the 'message' when using modbus ip function blocks, so the gateway knows where to forward the message?
