In regards to the METSEPM8000DEMOT , METSEPM8000DEMOK , METSEPM8240DEMO , METSEPM8244DEMO How does NTP/SNTP time sync work in PM8000?
The PM8000 accepts a time sync signal via communications from Power Monitoring Expert and PowerSCADA Expert, NTP via Ethernet connection, IRIG-B via onboard digital input or a signal from a GPS clock via RS485. The GPS clock signal and IRIG-B sync methods both result in +/- 1 millisecond time stamp accuracy across all synchronized meters. NTP provides approximately 20ms accuracy or 1 electrical cycle. The time sync signal from the supervisor software provides about +/- 1 second accuracy.
