How do you perform a "Query" of the controller executive using the Unity Pro OS loader utility?



From the Modbus Plus Target screen, you can scan your network and select the Modbus Plus Target Address by highlighting the Node and then select the Properties button. Note that you can also use the USB or Modbus link.
You will be prompted to "Stop" the PLC during this operation.

You can also perform the same task with a Premium using USB or Unitelway.

Connecting via TCP/IP (FTP) is not an option as the Query will result in the Ethernet Coprocessor firmware version and not that of the CPU.

Another window will open showing Device Properties.
