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
