How panel800 access to AC800M variables and alarms, events
As i knew, panel800 use control network and MMS to access AC800M.
But the question is how it works in deep? panel800 as OPC server, MMS server?
Here is comparsion: ABB PCU could use "access variables"->address "MMS" in compact control builder to access AC800M, but looks we do nothing in compact control builder that make panel800 access AC800M possible.

Hi,
In compact control builder you have to put the variables, that you need to exchange with the panel- tags in panel800, in MMS Access variables tab of the corresponding controller.
Then, you can easy import that list in panel builder (or create manually, of course) and it is working very fine.
About how the data is transferred between AC800M and panel, it is clearly defined in the name of driver in the panel - ABB Control Network MMS.
In addition, you can use integral alarm management via MMS - e.g. if the alarm is acknowledged in the panel, it is acknowledged in Compact HMI if there.
