Chapter 2 Create a Project for Integrated Motion on the EtherNet/IP Network
Set Time Synchronization
This technology supports highly distributed applications that require time
stamps, sequence of events records, distributed motion control, and increased
control coordination. All controllers and communication modules must have
time synchronization that is enabled for applications that use integrated
motion on the EtherNet/IPâ„¢ network.
Time synchronization in the Logix system is called CIP Sync. CIP Sync
provides a mechanism to synchronize clocks between controllers, I/O, and
other devices that are connected over CIP™ networks and the ControlLogix® or
CompactLogixâ„¢ backplane. The device with the best clock becomes the
Grandmaster time source for your system.

P1 and P2 = Priorities Priorities are automatically assigned based on their clock quality, which the Best Clock Algorithm determines. In this example, P2=1 is the
best quality so it becomes the Grandmaster. If the P2=1 device loses clock quality for some reason, then P2=2 would become the
Grandmaster for the system.
