AC800M to PANEL 800 (PP835)
I'm trying to get a Panel 835 to communicate with an AC800M over MMS.
I have my variables declared on the PLC, Compact Control Builder
I have the same variables imported into Panel Builder 800
I have assigned IP addresses to both PLC and HMI
I have downloaded user programs to both
I have both units connected via ethernet cables to the same hub.
I can ping both units at the assigned IP addresses. I can download user program changes to both.
I get a message on the HMI:
"1: Comm Error. 0"
Any thoughts on what I did wrong?
