Features:
- Compares information in a TELEPERM M redundant I/O arrangement.
- Supports switchover within the AS 235 H architecture.
- Works with the documented ES 100 K system configuration.
The exact 6DS1144-8AA code identifies the comparator/switchover function used by the high-availability controller layout.
Its system value comes from coordinated operation with the redundant I/O channels and the associated TELEPERM hardware.
Replacement planning should map slot, backplane and path designations before the original assembly is withdrawn.
Availability is confirmed against the complete 6DS1144-8AA identity, required condition, quantity and delivery destination at quotation.

- Maintain redundant I/O comparison in a TELEPERM M AS 235 H control system.
- Restore the engineered switchover path in an ES 100 K installation.
- Support planned legacy-system service without redesigning the complete I/O architecture.
- The module occupies the system position defined for AS 235 H redundancy.
- Both I/O paths must follow the ES 100 K engineering documentation.
- Backplane and field-side routing remain part of the complete switchover chain.
- A comparison discrepancy must be traced across both redundant signal paths.
- Switchover behavior should be tested under the approved maintenance procedure.
- Rack indications and system messages identify whether the fault is local or external.
- Use is limited to the documented TELEPERM M high-availability arrangement.
- The exact suffix must match the installed backplane and system generation.
- Mechanically similar 6DS modules can perform unrelated functions.
