What is the ControlLogix SynchLink Module?

Connecting a SynchLink Module to a SynchLink System
Using Module Identification and Status Information
Preventing Electrostatic Discharge
Removal and Insertion Under Power
A ControlLogix SynchLink module, through the use of fiber optic
communication technology, allows you to implement:
• time synchronization
• distributed motion control
• coordinated drive control
based on the ControlLogix and PowerFlex 700S platforms. In distributed
control system, the SynchLink module broadcasts reference data and
synchronizes time from a single ControlLogix chassis to multiple other chassis
at a high speed.

What Data Does the SynchLink Module Transfer?

The SynchLink module transfers multiple types of reference data between
chassis, including:
• Produced axis data for chassis to chassis remote axis control
• High speed drive reference data for chassis to drive control
• General control information that requires transfer at a high speed and in
a synchronized manner
