  • Page 40: Operation

    Operation 4. OPERATION 4.1. TIME SYNCHRONIZATION The preferred method of accurate time synchronization is achieved using 1588 PTP over an Ethernet network. The accuracy of the time synchronization is dependent on the Ethernet switching equipment, network architecture, boundary clocks, and end devices. Switches that are PTP enabled will allow for the best accuracy timing results as the randomness in the delay between packets being sent from and to the Time Sync module is at the lowest possible level.

  • Page 41: Positioning

    Operation NOTE: For further information regarding the announce interval, sync interval, priority 1, priority 2, and domain number refer to the additional information section 1.4 under CIP Sync and 1588 PTP. Switches and network architecture can also affect the time synchronization accuracy when using NTP.
