Extended subscriber-specific display and control options.
•

an internal interface.

Data point typicals In the subsequent program execution, call the data point typicals for sending and
receiving data. The sequence of the individual typicals is unimportant.
The number of typicals to call and the required types depend on the amount and
type of data to be sent and received.

The instance DBs of these FBs are referenced using the partner object number
of the communication partner.
