Features:
- Seats two IM 153-2 interface modules at the head of one ET 200M station.
- Extends both interface paths into the common active backplane.
- Allows documented interface-module insertion and removal while the station remains in RUN.
The two physical positions on 6ES7195-7HD00-0XA0 create the hardware boundary for the redundant ET 200M interfaces.
Both interfaces reach the same downstream station through the active backplane rather than separate I/O module lines.
Rail order and controller configuration must agree so a switchover uses the second IM 153-2 path correctly.
The Siemens 6ES7195-7HD00-0XA0 SIMATIC ET 200M Redundant Bus Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How the two interface positions work together
- Primary path: One IM 153-2 carries active station communication during normal operation.
- Standby path: The second IM 153-2 remains available to assume communication when required.
- Common station: Both paths lead to the same downstream ET 200M modules.
How data reaches the I/O modules
- Bus contacts: Plug-in contacts connect each interface module to the active backplane.
- Shared module line: The backplane continues from the bus unit through the configured I/O positions.
- Installed base: The bus unit stays fixed when an interface module is exchanged.
Placement rules that affect the station
- Head position: The redundant bus module is installed at the interface end of the rail.
- Module seating: Both IM 153-2 units must lock fully into their assigned connectors.
- Following modules: The remainder of the ET 200M station follows the documented bus-module sequence.
What to verify in a redundant station test
- Controller view: Both interface paths must appear in the hardware configuration.
- Path interruption: Removing one communication path should leave the other path available.
- Diagnostic record: Use controller diagnostics to confirm which interface carries the station.
