Best way to uniquely identify a UniStream® 15.6" PLC

Recommended Posts

What is the best way to uniquely identify a UniStream® 15.6" PLC with software?

Several PLCs are connected to a network with Ethernet cables and they are monitored/controlled by another equipment. I would need to be able to uniquely identify every connected PLCs to make sure, for example, that a PLC connected to given IP address is the expected one.

I have read on ASCII String to MI? that the best way to do that was to retrieve the CPU MAC address. Is it still the best way today?

That makes sense but, unfortunately, the `System.CPU HW Version.Serial Number` tag just display "Serial Number". So it does not uniquely identify a PLC. I would have expected the same number as the one printed on the sticker at the back of the panel or the CPU module.

This is a screen shot taken with VNC Viewer (other ID tags have been blurred):
