Hi, I'm trying to integrate my Modbus TCP Server Device. I've tested it using ModScan32 but I have no success with Ignition.
My device appears connected but I'm not able to read the registers values using the OPC Quick Client. I've tried different approaches: using and removing '4' prefix for modbus address, using different device Id and registers names, I didn't have luck!
Modscan is polling four registers, but you are trying to poll five registers. Consider not using the address mapping feature of the driver (no longer recommended by the IA driver author), but use manually constructed OPC item paths in your Ignition tags.
Thank you! I've tried with creating the constructed OPC item but I got the following. I'm missing something or should I try to setting OPC Server, enable firewall? I'm just stuck with this!
As you can see, we are reading the reg1 value 101, that's is correct, but why in the Ignition Designer - OPC tag shown 'bad' value? My PC which running Ignition is connected to WiFi Adapter and not Ethernet, that would be the problem?
