Siemens 6ES7153-2AR03-0XA0 documented automation component

6ES7153-2AR03-0XA0 is documented by the cited source as a redundant distributed-I/O interface bundle with a defined role in an industrial automation system.

System function

Rebuilt from individual evidence

Evidence and limits

The cited Siemens source identifies 6ES7153-2AR03-0XA0 as a redundant distributed-I/O interface bundle.

The same exact-reference source documents this function and interface detail: Provides redundant distributed-I/O interface modules for a PROFIBUS DP distributed-I/O station.

The system position is an inference from the documented interface and function; installation-specific compatibility remains unknown.

System role

This section explains what the product does and where it acts in the surrounding system.

Function: Supplies redundant distributed-I/O interface modules for a PROFIBUS DP distributed-I/O station.
System position: Sits between the redundant DP-master path and the distributed-I/O modules.
Upstream / inputs: Receives the redundant PROFIBUS DP station connection.
Downstream / outputs: Carries process data to and from the distributed-I/O modules through the bundled interfaces.
Limitations: Unknown: Installation-specific compatibility, wiring, firmware, project configuration, condition, and commercial status are not established by this lookup.

Inferences

The module's system position is inferred from its documented interface and function: Sits between the redundant DP-master path and the ET200M I/O modules.
Confidence: medium
Rationale: The cited exact-reference identity and function evidence supports this system-path description; the placement is explicitly an inference.
