3.2 Telecontrol
Communications:
· Parameter-settable telecontrol functions with or without time tagging
· Communication via selectable protocols to arbitrary superior automation units
· Monitoring of the communication upon failure
· Automatic or selective data flow routing
· Priority based data transmission (priority control)
· Own circular buffer and process image for each connected station (data keeping)
· Communication within the automation unit
· Special application specific functions for dial-up traffic
─ Test if stations are reachable
─ An application program may evaluate telephone charges
─ Parameter setup allows the telephone line to be used efficiently with respect to connection
charges (e.g. command output possible only if a connection exists)
Process Periphery:
· Acquisition and preprocessing of local peripheraly (monitor direction)
─ Single-point and double-point information items
─ Counting pulses
─ Currents and voltages
─ Frequencies
· Postprocessing and output to local periphery (control direction)
─ Single-point information items
─ Single and double commands
─ Setpoint values via currents and voltages
· Transmission of spontaneous information objects from and to peripheral elements, via the se-
rial TM bus
· Monitoring of the I/O modules, failure management
· Archiving of events
