dub Posted April 3, 2018 Report Share Posted April 3, 2018 I can't configure program for 3VFD-s on MODBUS 485 RTU protocol. PLC comunicate only with first one. depending on what I call the first one. I try with all three in the first place and everyone is doing this, which means that the parameters are correct in them. I know the PLC can only communicate with one at a time but I do not know how to write it. V1210 and 3 VFD-s -MODBUS RTU.vlp Quote Link to comment Share on other sites More sharing options...
