1-2 What is the 1756-SYNCH module?

Why Synchronize Time Between Chassis?

In synchronizing time between chassis, the SynchLink module allows you to:

• share motion data from chassis to chassis because a consistent time

reference is available among chassis for interpolation of velocity and

position data.

• timestamp I/O in multiple chassis and have a common time reference

with which to compare the timestamps.

For more information on how the SynchLink module impacts the time

references between ControlLogix chassis, see Chapter 2, Time

Synchronization in the ControlLogix System.

What Are Some of the Features Available On the ControlLogix

SynchLink Module?

The following are some of the features available on the ControlLogix

SynchLink module:

• Support of multiple SynchLink system configurations - Star, daisy chain

and ring

For more information on these functions, see Chapter 2, Time

Synchronization in the ControlLogix System.

For more information on how to configure the module with RSLogix

5000, see Chapter 5, Configuring the SynchLink Module.

• Removal and insertion under power (RIUP) - This system feature allows

you to remove and insert the module while power is applied. For more

information on RIUP, see page 1-6.

• Communication of remote axis data in a timely and

deterministic manner

• Communication of direct and buffered data

• Class I Division 2, UL, CSA, and CE Agency Certification
