I'm trying to connect to a TCP modbus server running on the same machine as the instance of VTSLite. I've confirmed the server is operating (with a different client), but I can't seem to get my VTS application to write or read any addresses.
I've followed the process here to make my tags, using "localhost" as the IP address and the same port as my server (standard 502) https://www.youtube.com/watch?v=Clt2uEIuL-E
I've tried different modbus addresses, but it doesn't seem like it's actually hitting the server at all. Opening up the trace viewer and attaching it to my application... I see absolutely nothing. Is there an obvious configuration step I might have missed? My tag configuration is shown below.
If there's not anything obviously wrong, can someone point me in the direction of some instructions for using the trace viewer? It seems straight forward but maybe I'm not using that correctly either.
