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
