I got an answer for this here a number of years ago: I was looking for a way to check the connection status of a GE PLC Ethernet port to Cimplicity HMI software. Can't find my original post, but I was told that $CONN_STATUS_P1C1 and $CONN_STATUS_P1C2 system tags would allow me to verify that I had network connection between the PLC and the HMI workstation. That worked like a champ. Now, we are in the midst of migration from Cimplicity to Citect, and the same tags are not recognized by Citect. Since we now only have 1 GE PLC instead of the 5 we used to have (been replacing them with Triconex), the tag issue is a minor but real bother. I am pretty sure that these system tags would also have a real memory address space, just not sure what that might be.
Anyone point me in the right direction? TIA
