Features:
- The 12.1-inch resistive touch screen presents an 800×600 process display without fixed function keys.
- Ethernet, RS 422, RS 485, and USB connections link controllers, storage media, and external input devices.
- CF, MMC, USB, and network destinations support project transfer and runtime archiving.
The MP 377 runtime combines process screens with alarms, recipes, trends, and user administration.
Onscreen numeric, alphanumeric, and hexadecimal keyboards supply the text-entry functions normally assigned to hardware keys.
Front sealing applies only after installation in the documented cutout; the rear electronics retain a separate IP20 boundary.
The Siemens 6AV6644-0AA01-2AX0 MP 377 12-inch Touch Panel may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Alarm handling: Runtime views present messages, acknowledgments, and buffered event records.
- Recipe work: Recipe records can be edited at the panel and moved between internal and removable storage.
Controller and peripheral connections
- Ethernet pair: Two RJ45 connections carry PROFINET and supported TCP/IP communication.
- RS 485 path: MPI and PROFIBUS controller traffic share the documented serial bus interface.
- RS 422 path: A separate serial channel serves drivers that require RS 422 signaling.
- USB access: Two USB ports accept supported storage, keyboard, mouse, or barcode-reader devices.
Data retention choices
- CF slot: CompactFlash can hold project transfers and runtime archive files.
- MMC slot: The multimedia-card path provides a second removable medium independent of CF.
- Network target: Ethernet storage moves archive data away from the panel's local media.
- CSV records: Process-value and message archives can be stored in a readable tabular format.
Front and rear boundaries
- Opening size: The 310×248 mm cutout locates the display in the cabinet face.
- Installation depth: Connections and electronics occupy 72 mm behind the mounting surface.
- Front protection: Correct installation establishes the IP65 and NEMA 4/12 front seal.
- Rear exposure: The IP20 rear section must remain inside a suitable enclosure.
