Schneider Electric TSXP57104M Unity PLC processor

TSXP57104M is documented as a Unity PLC processor for an industrial control system. Verify the exact installation context before sourcing, repair, exchange, or replacement.

Documented product identity

Rebuilt from individual evidence

System function and position

The cited exact-reference source identifies TSXP57104M as a Schneider Electric Unity PLC processor.

The second cited source records the exact commercial reference TSXP57104M in a technical product or connection record.

The documented Unity PLC processor therefore occupies the control path between its upstream inputs and the downstream process.

Unknown: The installed firmware, application or network configuration, and hardware condition are not established by the cited sources.

Exact reference: TSXP57104M
Category: PLC / CPU

System role

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

Function: Controls the PLC station by executing the Unity application program for a Modicon Premium PLC station.
System position: Sits in the Modicon Premium rack as the central controller between rack modules and the controlled process.
Upstream / inputs: Receives the configured control program and signals from the documented upstream system.
Downstream / outputs: Updates or transmits the documented control output toward the downstream process.
Limitations: Unknown: The installed firmware, application or network configuration, and hardware condition are not established by the cited sources.
