SynchLink
SynchLink provides time synchronization and data broadcasting capabilities for
distributed motion and coordinated drive control.
1756-SYNCH SynchLink module
The 1756-SYNCH SynchLink module connects a ControlLogix chassis to a SynchLink
fiber optic communications link. The module:
y
coordinates CST time across multiple ControlLogix chassis
y
moves limited amount of data from one chassis to another at a high speed
y
lets one controller consume motion axes data from a controller in another chassis
