Chapter 4 EtherNet/IP Protocol

CIP Sync

CIP Sync defines time synchronization services for CIP. Time synchronization

on the EtherNet/IP network is a method to synchronize clocks across devices on

the network. In a synchronized application, there is a single time master and

multiple time slaves. For example, a ControlLogix controller can be configured to

act as the time master and other ControlLogix modules, connected via

EtherNet/IP communication modules, serve as the time slaves.

You can synchronize the clocks within the following applications:

• Multiple ControlLogix controllers

• ControlLogix redundancy systems

• Real world clocks

• Personal computer-based events
