Audio-Frequency Remote Control (AFRC)
The integrated AFRC features of the IDS HIGH-LEIT SCADA system enable the user to carry out all the AFRC-relevant configuration and monitoring tasks. The complete integration of the AFRC functions into the SCADA system’s user environment ensures easy and user-friendly operation.
AFRC Features in IDS HIGH-LEIT:
- Integration of AFRC functions into the alarm and optimization functions
- Creation of complex schedules
- Event-controlled triggering (signal, optimization) with limitation of validity
- Load-controlled triggering through load control in the network control system
- Manual triggering through operating personnel
The integration of the AFRC system into the hardware is done through expanding the IDS 850 RTU by an additional module into a local AFRC controller RK 850, thereby providing a communication infrastructure for telecontrol and audio-frequency remote control.
Features of the AFRC System:
- Utilization of secure telecontrol protocols according to IEC 60870-5-101/-104
- Utilization of redundant communication pathways
- Complete control and monitoring of audio-frequency transmitters
- Management and processing of command
- Triggering of AFRC commands through local digital inputs
- External output of commands from the SCADA system or from the emergency operation level
- Immediate check of the pulse sequence via pulse filter
- Support of the synchronized mode in connected networks
- Support of telegrams fort he remote parameterization of receivers
- Local connection of notebook for emergency operation
- Decentralized time synchronization
