Hey guys, It may be something Im overlooking but I am using the Modbus TCP Library from the PLCnext Store and Im having trouble connecting to the server FB from a remote Client. I cant find a way to specify a unit ID to connect to it when my software requires a Unit ID. I read and write as a client with no issues but I am unable to initiate an external request successfully. Any ideas or suggestions?

As mentioned in reply to your question through other support channels, The MB_TCP_Server does not support this function. There is no way to set the Unit ID at the function block.
