- Distributes synchronized timing and reference information across compatible control chassis
- Supports engineered star, daisy-chain, and ring SynchLink architectures
- Requires coordinated fiber routing, time-master assignment, firmware, and controller configuration
1756-SYNCH is an Allen-Bradley ControlLogix SynchLink communication module for deterministic fiber-optic synchronization.
It exchanges synchronized time and motion-reference information between compatible chassis and drive systems while the standard control network handles ordinary control communication.
Before replacement, preserve the CST time hierarchy, topology, fiber-port routing, controller project, electronic keying, and firmware record.
Availability, condition, price, and shipping time for 1756-SYNCH are confirmed during quotation.

- Preserve the engineered star, daisy-chain, or ring arrangement during replacement
- Record transmit and receive routing at both fiber ports before disconnecting cables
- Confirm every node remains in the intended optical path after installation
- Maintain one approved CST Time Master for the complete SynchLink system
- Verify each synchronized chassis and drive follows the correct time hierarchy
- Restore the approved controller and drive configuration before enabling motion
- Inspect fiber connectors, routing, attenuation, and port status when synchronization is lost
- Check firmware, electronic keying, chassis power, and controller project references
- Validate synchronization and coordinated motion under controlled conditions before production
- Distributed motion systems requiring deterministic time coordination
- Multi-chassis drive systems exchanging synchronized reference data
- ControlLogix architectures built around a documented SynchLink time hierarchy
