FAQ
FAQ
Q1: What is the primary function of the 1756-SYNCH module?
The 1756-SYNCH module synchronizes Coordinated System Time (CST) across multiple ControlLogix chassis and enables high-speed motion data sharing over SynchLink fiber optics.
Q2: What communication media does the module use?
The module uses SynchLink duplex fiber optic communication with dedicated transmit and receive fiber ports.
Q3: What is the communication speed of the module?
The SynchLink network operates at 5 Mbps synchronous communication speed.
Q4: What is CST synchronization used for?
CST (Coordinated System Time) synchronization allows multiple ControlLogix chassis and motion systems to operate using the same precise timing reference for coordinated motion applications.
Q5: Which applications commonly use the 1756-SYNCH module?
Typical applications include coordinated motion control, transfer presses, synchronized drive systems, and distributed multi-chassis motion control.
Q6: What are the physical dimensions of the module?
The approximate dimensions are 145 mm (H) × 35 mm (W) × 140 mm (D).
Q7: Is the module still available from Rockwell Automation?
Yes. Rockwell Automation currently lists the 1756-SYNCH as an active product.
Q8: What important system limitation should be considered?
Rockwell documentation states that a maximum of 10 SynchLink connections can be used within a system configuration.
