Product Overview
The S7-400H synchronization module forms the redundant fiber-optic link between the two H-system CPUs and is installed in matched sets for fault-tolerant operation.
The module transports synchronization data between the two CPUs of the H system. Two modules per CPU are connected in pairs to create the redundant communication paths. Synchronization modules can be exchanged under the documented hot-swap procedure without stopping the entire plant.
Key Functions
Redundant CPU Synchronization
The module transports synchronization data between the two CPUs of the H system.
Paired Fiber-Optic Links
Two modules per CPU are connected in pairs to create the redundant communication paths.
Hot-Swap Serviceability
Synchronization modules can be exchanged under the documented hot-swap procedure without stopping the entire plant.

Frequently Asked Questions
How many synchronization modules are needed with 6ES7960-1AA00-0XA0 in an H system?
Install two per CPU, with four matching modules in the complete redundant controller pair.
Why must all four units match when using 6ES7960-1AA00-0XA0?
The H system requires synchronization modules of the same type on both redundant links.
Which cable connects 6ES7960-1AA00-0XA0 to its paired module?
Use the approved fiber-optic synchronization cable for the installed S7-400H distance and hardware generation.
Can 6ES7960-1AA00-0XA0 be replaced while the plant remains in operation?
Hot swapping is supported only when the documented redundancy condition and service procedure are satisfied.
How should unused optical interfaces on 6ES7960-1AA00-0XA0 be protected?
Keep the supplied protective plugs fitted so dust cannot reduce optical performance.
What should I check before removing 6ES7960-1AA00-0XA0?
Verify H-system redundancy, identify the correct link, inspect diagnostics and prepare the approved swap sequence.
What must be confirmed after fitting 6ES7960-1AA00-0XA0?
Check module seating, optical cleanliness, both synchronization paths, redundancy status and the CPU diagnostic buffer.
Compatibility & Ordering Notes
Compatibility Checklist
- Use four synchronization modules of the same documented type in the H system.
- Protect every optical interface from contamination and mechanical stress.
- Verify both redundant links and CPU diagnostics after service.
