Function
Remote data forwarding
Collect telemetry, remote signaling, electrical measurement, and time scale data from the controller and send them to the scheduling system; Receive remote control, remotely adjust and send to local control logic
Redundancy of primary and backup links
Can be configured with dual COM0002 redundancy, automatic switching in case of link failure without losing data
Breakpoint cache
Broken link cache measurement point, resend historical time stamp data after communication is restored
Complete message diagnosis
Panel indicator light+system alarm: communication interruption, verification error, slave offline, link timeout
IRIG-B time synchronization
Support external clock synchronization to ensure unified time scale of all station measurement points
