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