Jejpi23 Posted September 20, 2022 Report Share Posted September 20, 2022 Hello I'm using USC B10 TR22 with UAC CB 01RS4_0 as modbus communication dev. I am communicating with HAMILTON VisiFerm DO Arc 120 but the Modbus status is 3 and thus there is no connection. I checked with HAMILTON programmer and the modbus in sensor is working correctly (image 1). I checked with the Logic Analyzers from Saleae and the commands from PLC are "going" but there is no reply from sensor. Is there anything wrong with my program ? (imige 2,3,4,5); Quote Link to comment Share on other sites More sharing options...

pascal Posted September 28, 2022 Report Share Posted September 28, 2022 I think this isn't modbus. When you look at the request string you must send, this appears to me that isn't modbus... You can try to communicate with message composer modbus requests are like this Quote Link to comment Share on other sites More sharing options...
