System function

Rebuilt from individual evidence

Evidence and limits

The cited Siemens source identifies 6ES7142-1BD22-0XB0 as BM142 four-channel 24 V DC digital-output module.

The same exact-reference source documents this function and interface detail: Switches four documented 24 V DC digital outputs in the documented field-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: Switches four documented 24 V DC digital outputs in the documented field-I/O station.
System position: Sits within the documented field-I/O station between the PROFIBUS DP controller and connected 24 V DC loads.
Upstream / inputs: Receives output data from the documented PROFIBUS DP station interface.
Downstream / outputs: Drives the connected 24 V DC field loads through four digital outputs.
Limitations: Unknown: Installation-specific compatibility, wiring, firmware, project configuration, condition, and commercial status are not established by this lookup.
