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?

actually this issue I did not see it before, but I would like to recommend you to check
- panel builder version and firmware version do you used and please install newest firmware for this panel.
- when does this issue happen? is it on every dispaly or partical dispaly? if it is how many elements do you used in this dispay? maybe too much dynamic elements in display will cause this issue.
