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.
