4.1.1 Stand-alone application

The control system (controller) and visualisation (Visu) run on separate controllers, respectively.

• The visualisation IPC (Visu IPC) directly communicates with an external control system and the

lower-level field devices. A fieldbus or a higher-level Ethernet network are used for

communication.

• The visualisation can access variables of the control system and (depending on the bus system)

in addition can directly access parameters of the field devices.

• For the visualisation, a Panel PC/Industrial PC Embedded Line or a control cabinet PC with an

external monitor panel can be used.
