Product Overview
The 6AV7422-2FC03-0AS0 is Siemens’ OEM-variant MP 377, a 12-inch color TFT touch multi-panel positioned in the SIMATIC HMI MP 370/MP 377 family as the widescreen 12″ node, supplied through OEM channels (commonly associated with eLAU/package-printing line integrations) rather than the standard catalog MP 377 retail SKUs (6AV7872 / 6AV7880 series). The 6AV7422-2FC03-0AS0 carries a 12″ color TFT at 1280 × 800 (WSGA widescreen), driven by a ~400 MHz RISC host under Windows CE 5.0, with 12 MB of configurable user memory programmable from WinCC Flexible 2007. The “OEM MP 377” designation matters — mechanically the 6AV7422-2FC03-0AS0 keeps the aluminum front bezel with uniform clamp mounts and IP65 front rating of the standard MP 377 line, but the interface mix (USB, Ethernet, RS-232, and typically MPI rather than full PROFIBUS DP on the OEM build) is trimmed to the host OEM’s bill-of-materials, which is why the 74xx prefix diverges from the 78xx retail MP 377 codes.
In the automation stack, the 6AV7422-2FC03-0AS0 sits as the visualization head for mid-size SIMATIC S7-300/S7-400 nodes or S7-1200/1500 legacy-migration cells where a 9″ Comfort panel lacks canvas and a 15″ MP 377 is oversized. The 12″ widescreen at 1280×800 is the sweet spot for packaging-machine P&IDs, reel-diagram graphics, alarm banner + recipe pane + trend strip on one screen without heavy popup nesting. For plants running WinCC Flexible 2007/2008 SPx projects on installed MP 377 fleets, the 6AV7422-2FC03-0AS0 drops in as a like-for-like OEM spare — same cutout envelope as the 6AV7872-0AA30 (MP 377 12″ key+touch) though the 6AV7422-2FC03-0AS0 is touch-primary — and preserves the existing WinCC Flex project binary through the MP 377 firmware lineage. Although Siemens has transitioned the MP 377 family into the Comfort (TP1200/1500) and Unified paths, the 6AV7422-2FC03-0AS0 remains an active spare-line and retrofit BOM item for hundreds of OEM-packaging and converting lines where re-validation onto a TP1200 triggers a machine-doc cycle the OEM prefers to defer.

Main Features and Advantages
The 6AV7422-2FC03-0AS0 is built around the MP 377 platform’s “big canvas, long life” philosophy, but the OEM 74xx prefix signals a BOM tuned for a specific machine-builder rather than the full-feature retail MP 377. The 12″ widescreen TFT at 1280×800 is the headline — roughly 2× the pixel width of a 10.4″ 800×600 SVGA panel, letting a packaging-machine HMI carry a reel-diagram strip left-to-right, an alarm banner top, a recipe/data-entry pane bottom, and navigation tabs right, all visible simultaneously. For OEM lines where the 6AV7422-2FC03-0AS0 is the face of the machine, this canvas size is the reason the MP 377 12″ persists even as 7″ and 9″ Comfort panels have taken the commodity volume.
Windows CE 5.0 on the 6AV7422-2FC03-0AS0 keeps the firmware lean — no TIA Portal requirement, just WinCC Flexible 2007/2008 SPx, which matters for service teams maintaining fleets of S7-300/400 machines where the HMI project is ten years old and nobody wants to migrate it into TIA. The 12 MB user memory sounds small by 2025 standards, but for a WinCC Flex project with bitmaps, alarms, recipes and a few trends on a 12″ screen, 12 MB is workable — the 6AV7422-2FC03-0AS0 isn’t hosting SQL or web-HMI; it’s showing tag values, acknowledging faults and letting the setter adjust reel-tension or fill-volume setpoints. The 400 MHz host CPU handles that workload without sweat, and the aluminum front with uniform clamp tabs gives the 6AV7422-2FC03-0AS0 the same rugged envelope as the retail MP 377 — IP65 front, wipe-clean bezel, resistant to the ink mist and solvent wipe-down common on converting and label-print lines where this OEM SKU shows up most.
Interface mix on the 6AV7422-2FC03-0AS0 is pared vs. the retail 6AV7872: Ethernet for connection to the S7-300/400 PG/OS rack or a PCS 7 OS client proxy, RS-232 for a barcode scanner or small printer at the machine side, USB host for recipe/archive flash-drive drops and a mouse during commissioning. The MPI interface (typical on the OEM build) lets the 6AV7422-2FC03-0AS0 hang directly off an S7-300 CPU’s MPI port or an S7-400 via a CP 341/CP 443 proxy without a PROFIBUS DP license — this is the trade-off in the 74xx OEM BOM vs. the 78xx retail which carries full PROFIBUS DP. For plants whose cell is MPI/MPI-DP bridge anyway, the 6AV7422-2FC03-0AS0 saves the DP-connector cost; for pure PROFINET greenfields, this is the wrong SKU and the TP1200 Comfort is the right successor.
