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
