Siemens 6ES7195-7HD10-0XA0 SIMATIC DP Bus Module ET 200M

Overview

The 6ES7195-7HD10-0XA0 is a SIMATIC DP bus module for ET 200M. Siemens identifies it as a bus module designed to hold two IM153-2 redundant interface modules and to support removal and insertion during RUN operating time. Siemens also lists it as a spare part / active product, which places it directly in the installed-base support path for ET 200M stations that depend on redundant interface hardware.

This product belongs to the mechanical and functional backbone of an ET 200M station. It is not a PLC CPU, not a signal I/O module, and not an HMI accessory.

Its role is tied to the rack-side arrangement of redundant IM153-2 modules and to service behavior during operation. In systems where ET 200M redundancy is already part of the control layout, this part supports that original hardware concept without changing the station structure.

Technical Data

Application Value

This module is intended for ET 200M distributed I/O systems that already use redundant IM153-2 communication interfaces.

It belongs in installations where the original cabinet design requires the ET 200M hardware arrangement to remain unchanged and where module handling during operation is part of the service concept. 

That makes it directly relevant to process-control cabinets, infrastructure panels, and other systems built around Siemens redundant distributed I/O hardware.

Because this is a rack-structure component, it matters in a different way than ordinary spare I/O.

The part affects how the redundant interfaces are physically supported and how the ET 200M station maintains its intended service behavior. In replacement work, keeping the same bus module helps preserve the original station layout and the original maintenance procedure.

Selection Notes

For selection, the key points are straightforward: the station must be ET 200M, the interface arrangement must require two IM153-2 redundant modules, and the installed system must depend on removal/insertion during RUN. Those are the core compatibility points for this product.

FAQ

Q1: What exactly is 6ES7195-7HD10-0XA0?
It is a SIMATIC DP bus module for ET 200M, built to hold two IM153-2 redundant interface modules.

Siemens defines it as a part that supports removal and insertion during RUN operating time, so it belongs to the station’s redundancy-ready bus structure rather than to the normal I/O signal layer.

Q2: Is this a normal I/O module?
No. It is not described by Siemens as a digital or analog signal module. It is a bus module used in the ET 200M hardware arrangement.

That distinction matters because its function is tied to how redundant interface modules are held and serviced in the station, not to field-signal processing.

Q3: Why is RUN-time removal and insertion important?
Siemens explicitly identifies this model with removal and insertion during RUN operating time. In practice, that means the part is used in systems where service continuity is built into the hardware arrangement.

That is a relevant feature in installed ET 200M systems where maintenance must be performed without changing the original station concept.

Q4: Where is this module usually used?
It is used in ET 200M stations that already employ redundant IM153-2 interfaces.

That makes it suitable for distributed automation racks, plant control cabinets, and other Siemens-based systems where redundancy is already part of the installed design.

Q5: What should be checked before ordering?
Check the installed part number, confirm the station is ET 200M, verify that the setup uses two IM153-2 redundant interface modules, and make sure the original system depends on the same RUN-time replacement function.

Those points determine whether this bus module matches the existing hardware structure.
