Product Overview

The 6AV7422-2FC03-0AS0 is Siemens’ SIMATIC MP 377 15″ Touch in the OEM packaging variant — the 6AV74xx prefix denotes an OEM/special-build SKU (commonly associated with ELAU packaging lines, machine-tool builders, and large OEMs who standardize the MP 377 under their own BOM header), while the functional and mechanical twin is the standard 6AV6644-2AB01-2AX0. Both share the same 15.1-inch TFT at 1024×768 and 64 K colors, resistive touch overlay, ARM-class processor at ~400 MHz, Windows CE 5.0 runtime, and 12 MB configurable user memory (with larger system Flash/RAM on the board layer). The 6AV7422-2FC03-0AS0 sits at the top of Siemens’ WinCC Flexible-era Multi Panel family — above MP 277 (6 MB, smaller screens) and below nothing until the Comfort range (TP1200/1500) succeeded it post-2015. Configuration is native in WinCC Flexible 2007 or later; TIA Portal cannot directly download to the 6AV7422-2FC03-0AS0 — it can import the Flexible project for migration only, meaning plants still running S7-300/400 or S7-1200/1500-with-Flexible retain this panel as the largest-screen key-heavy alternative before forced migration.

The 6AV7422-2FC03-0AS0 differentiates from the 12″ MP 377 (6AV6644-0AA01) and 19″ (6AV6644-0AC01) by screen real estate: 15″ is the sweet spot for machine-tool cabin doors, large packaging OEM fascia panels, and process skid local operator stations where a 12″ feels cramped for 50+ tags per screen but a 19″ won’t fit the cutout. Interface density is the MP 377 hallmark — MPI/PROFIBUS DP on one RJ45 cluster, two independent Fast Ethernet (PROFINET/TCP/Modbus TCP), RS422/485 on a second D-sub, two USB host ports (mouse, keyboard, printer, stick), and dual storage slots (CF card primary, SD/MMC secondary) for recipe/alarm CSV archival and project backup. The front bezel is aluminium with uniform clamps (OEM builds often specify this for machine-tool door mounting where steel bezels corrode or dent), IP65 front / IP20 rear, 24 V DC at ~20 W max. The MP 377 family went PM410 (cancel/discontinue) circa 2017, so the 6AV7422-2FC03-0AS0 today trades almost exclusively as tested-refurb or NOS spare for cells that cannot yet justify the TP1500 Comfort + TIA migration cost.

Main Features and Advantages

OEM packaging with standard MP 377 15″ hardware. The 6AV7422-2FC03-0AS0 is functionally identical to the catalogue-listed 6AV6644-2AB01-2AX0 — same 15.1″ 1024×768 TFT, same ARM ~400 MHz, same 12 MB user memory, same port set — but ships under the 6AV74xx OEM prefix, typically with an aluminium front bezel and uniform clamps specified by machine-tool / packaging OEMs (ELAU heritage, SINUMERIK cells, large-form-fill-seal lines). For spare buyers, this means spares and refurbs of either SKU are cross-deployable: a failed standard 6AV6644-2AB01 in an OEM machine can take a 6AV7422-2FC03-0AS0 drop-in, and vice versa, provided the cutout/clamp pattern matches (the OEM “uniform clamps” are spaced to the same MP 377 15″ door template). The OEM splash screen may differ (OEM logo instead of Siemens default), but the WinCC Flexible runtime, tag table, and hardware driver set are identical.

Dual-Ethernet + MPI/DP + RS422 on one panel. The 6AV7422-2FC03-0AS0 carries the richest port mix of the Flexible-era flagships: two independent 10/100 Ethernet ports (port 1 typically PN/PROFINET IO, port 2 TCP/Modbus TCP/SCADA uplink), one RJ45/MPI-DP cluster for S7-300/400 back-end, RS422/485 for third-party drives or scales, and two USB 1.1/2.0 host ports. For a large packaging OEM cell — say an ELAU PacDrive S7-315T + SINAMICS rings + upstream barcode + downstream palletizer — the 6AV7422-2FC03-0AS0 collapses what would be three interface cards on a lesser panel into one RJ45 cluster plus the second Ethernet. MPI saturation is avoided by putting the HMI on DP or PN while the PG takes MPI, or vice versa depending on cell topology.

12 MB user memory + CF/SD dual-archive. The 6AV7422-2FC03-0AS0 gives 12 MB configurable in WinCC Flexible — double the MP 277 (6 MB) and enough for 1000+ tags, 500+ screens, recipe CSVs, alarm buffers, and f(t) trending on a medium-complexity cell. Archive storage goes to CF card (primary, Siemens-qualified ≤2 GB industrial CF) and/or SD/MMC (secondary, ≤2 GB qualified). For batch/pharma cells that need CSV recipe-export to a stick or network share, the 6AV7422-2FC03-0AS0 handles it without an external PC; the second Ethernet port can land on the MES VLAN while port 1 stays on the machine PN ring — traffic separation that the single-Ethernet KTP/Basic panels cannot do.

Aluminium bezel & uniform clamps for machine-tool doors. The OEM 6AV7422-2FC03-0AS0 typically specifies an aluminium front (vs. the standard’s mix of aluminium/plastic depending on batch) with uniform clamp spacing — important when the panel mounts on a swinging machine-tool cabinet door or a washdown-adjacent packaging fascia where steel bezels show rust spots after 3–4 years. The clamp system allows tool-less removal from the front after loosening four bolts from inside the cabinet, which service techs appreciate on 3-shift lines where the HMI is the first thing the operator blames for any fault.

Sm@rtService / Sm@rtAccess & scripting. The 6AV7422-2FC03-0AS0 supports Siemens’ Sm@rtService (remote dial-in / VPN maintenance) and Sm@rtAccess (cross-HMI screen viewing) — OEMs with fleets of machines at customer sites 500 km away use this heavily. WinCC Flexible on the MP 377 also supports VBScript subsets for math pre-processing (recipe scaling, unit conversion, checksum) before writing to the S7 DB — something the Basic panels (KTP) cannot do and the Comfort panels moved to C-style scripting, so plants with heavy Flexible-VB logic cling to the 6AV7422-2FC03-0AS0 as long as the S7-300/400 CPU lasts.
