Configure the System Redundancy Module 61
Change
Auto-Synchronization
You can control when the 1757-SRM module tries to synchronize the
controllers.
Perform this procedure to:
• help synchronize the system.
• prevent the system from crossloading changes.
Actions
Action Details
1. Decide when you want the system to
synchronize.
Do you plan to manually disqualify a chassis so you can make changes?
• No — Choose Always
• Yes — Choose Conditional
2. Open the SRM configuration tool for the
primary chassis.
A. Start RSLinx software.
B. From the Communications menu, choose RSWho.
C. Open the branches of your network until you find the 1757-SRM module in the primary
chassis.
D. Right-click the SRM and choose Module Configuration.
If you choose Then
Conditional The SRM keeps the synchronization command that you give it. If
you:
• synchronize the secondary, the SRM always tries to keep the
controllers synchronized.
• disqualify the secondary, the SRM keeps the controller
unsynchronized (disqualified). It does not crossload changes.
Never The controllers will not try to synchronize, but you can still manually
synchronize the controllers.
