Remote Operation and Monitoring
The network system enables the central control system to fully
access to the protection relays, and achieve remote monitoring of
the measurement values, operational status etc as well as
remote operation such as change of settings. Thereby efficient
operation and maintenance are realized.
- ModBus
(RS485)
- CC-Link
Remote Operation
- Measurement setting
- Relay setting
- Time Adjustment
Local Operation
Local Operation and Monitoring for Site Maintenance
By connecting PC with relay via the RS232C port located on the
relay panel, local operation and monitoring are enabled as same
as the remote operation and monitoring. Thereby the
maintenance work at site is strongly supported.
Remote Monitoring
- Measurement value
- Relay settings
- Relay operation status
