I use HMI Draw to develop apps for oil & gas well monitoring and control and I have the same problem. I have the same project app for multiple Oil & Gas well at the same location but ren into the problem of:
“How do I address each individual well on location via the local wireless network where all the wellhead control systems are on the same network?”
I resolved this issue by just creating multiple “Connectors” for the same HMI project and setting the tags for each connector to the different Modbus Slave Id’s. This way, when I open the Connectors Panel, I just select the connector with the appropriate Slave ID, close it when I am done, and open another Connector to view other wells.
