Terminology

(Online Status) Online:
When an HMI goes online, it sends keep-alive information to a keep-alive server and lets all EasyAccess 2.0 clients know it is ready for connection. There is still no connection in this state unless one EasyAccess 2.0 client connects to it.

(Online Status) Occupied:
When an EasyAccess 2.0 client connects to the HMI, then the HMI is occupied and no other EasyAccess 2.0 client can connect to it until it is disconnected.
