When three systems tell three different stories after a trip, your clocks are broken — here is how to fix time sync from the GPS antenna to the last 3500 rack.
Match the protocol to the accuracy your data actually needs, then stop the drift that scrambles event order. A practical guide to PTP, IRIG-B, NTP, and SNTP time synchronization for GE PACSystems controllers and Bently Nevada 3500 machinery protection systems.
Time synchronization errors between Triconex T3000 NTP clients and GE Mark VIe IEEE 1588v2 PTP controllers can corrupt Sequence of Events records and produce historian logging gaps. This guide covers NTP stratum configuration, PTP transparent clock requirements, a 5-step diagnostic procedure, and historian late data acceptance window settings.
