What is the 1756-SYNCH module?

This chapter describes the ControlLogix SynchLink module. It also describes

what you must know and do before using the SynchLink module.

What is the ControlLogix

SynchLink Module?

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
