MVP 2021 Joe Tauser Posted March 3, 2020 MVP 2021 Report Share Posted March 3, 2020 Moved to correct forum First look at the Modbus examples under Help- There are example programs for the V130, which will have the same Modbus commands as the V570. If you can post the programs you're using we can look them over and see what's going on. Also, what kind of cable are you using to connect them? Joe T.
