Product Overview

The Siemens 6AV7422-2FC03-0AS0​ is a SIMATIC MP 377 12″ Touch in OEM packaging — the 6AV7 prefix denotes Siemens’ OEM-specific build for machine builders and process-equipment OEMs, where the core MP 377 hardware is paired with an aluminum front bezel and uniform-clamp mounting instead of the standard poly-carbonate front of the 6AV6644 retail variants. Under the bezel, the 6AV7422-2FC03-0AS0​ is electrically and firmware-identical to the standard MP 377 12″ Touch (6AV6644-0AA01-2AX0): 12″ TFT at 800 × 600 with 65,536 colors, Windows CE 5.0 runtime, 12 MB user Flash/RAM, and the same interface set (MPI/PROFIBUS DP, 2× Ethernet RJ45, RS422, RS485, 2× USB, CF + SD/MMC slots). Configurable from WinCC Flexible 2007 onward, the Siemens 6AV7422-2FC03-0AS0​ runs the same .hsc project files as the standard MP 377 — a critical point for spare-pool managers, because an OEM-labeled panel can substitute for a failed retail-unit MP 377 on the same cutout without rescreening.The 6AV7422-2FC03-0AS0​ was Siemens’ answer to large OEM accounts (packaging machinery, printing presses, converting lines, bottling monoblocs) who wanted the MP 377’s interface density and 12 MB project headroom but demanded a more rigid aluminum faceplate and uniform clamp geometry that matched their enclosure-door cadence. The x86-class processor at ~400 MHz handles VBScript/C-Script logic, Sm@rtService remote access, and OPC server duties — the same reasons the MP 377 family became the HMI head-end on S7-300/400 cells and early S7-1500 retrofits. The Siemens 6AV7422-2FC03-0AS0​ is now PM490-discontinued (like all MP 377s), but NOS and verified-pull units remain the sanctioned spare for OEM skids that haven’t migrated their WinCC Flexible projects to TIA Portal Comfort panels.
