Siemens 6AV6 644-0AC01-2AX1 MP 377 15-inch touch panel HMI operator interface.

The Siemens 6AV6 644-0AC01-2AX1 is a Multi Panel MP 377 human-machine interface (HMI) featuring a 15-inch TFT touch display. This operator panel provides visualisation and control capabilities for industrial automation systems, enabling operators to monitor processes and input commands directly at the machine or production line level.

The MP 377 series is designed for integration with Siemens SIMATIC automation systems, communicating via PROFINET and PROFIBUS protocols. It serves as a key component in factory automation, process control, and manufacturing environments where reliable operator interaction with PLCs and control systems is required.

This is a legacy HMI panel from the Siemens SIMATIC HMI range, having been superseded by newer Comfort Panel and Unified Comfort Panel product lines. However, it remains widely deployed in existing industrial installations and is sought after for maintenance, repair, and like-for-like replacement purposes.
