Main Features and Advantages
12.1″ TFT color graphics on a Windows CE 3.0 runtime.
The 6AV6545-0DA10-0AX0 delivers a far richer operator experience than the STN or character panels of the same era—256-color TFT at 800×600 lets process graphics, trend curves, and bitmap-based machine mockups render cleanly. Running on Windows CE 3.0, the MP370 supports VBScript fragments inside WinCC flexible projects, meaning alarm filtering, math pre-processing, and cross-screen navigation logic can live on the panel rather than consuming PLC scan cycles.
Generous memory footprint for a legacy panel.
7168 KB of user memory plus nearly 6 MB of option memory is enough for several hundred screens, deep alarm buffers (2000+ fault/operating messages each), recipe sets, and trend archives—especially when combined with the CF card slot for offline bulk storage. For batch-reporting cells that log every valve stroke to CSV, the 6AV6545-0DA10-0AX0 handles it locally and dumps to CF for later pull.
Peripheral-rich connectivity without a PC.
Two USB hosts accept a barcode scanner (for material-ID entry at the line side), a compact keyboard (for password-protected recipe editing), or a mouse for offline commissioning. RS232 drives a panel-side printer for GMP-compliant hardcopy of batch alarms. MPI/PROFIBUS-DP connects natively to S7-300/400 at standard bus speeds, and the CF slot doubles as a project-clone vehicle—pull the card from a master 6AV6545-0DA10-0AX0, insert into a spare, and the line is back in minutes.
Rugged industrial envelope.
At 28 W from a 24 V DC rail, the MP370 generates moderate cabinet heat but nothing a standard 100 mm fan tray can’t handle. The analog-resistive touch tolerates gloved operation and survives the million-actuation class typical of polyester-faced industrial touches, while IP65 front foil shrugs off sprayed coolant, flour dust in food lines, and cleaning-agent overspray. The 50 k-hour backlight MTBF translates to 5–7 years of three-shift operation before dimming becomes noticeable.
Engineering continuity.
For plants sitting on a library of ProTool or WinCC flexible 2004 projects, the 6AV6545-0DA10-0AX0 means zero re-engineering. No TIA Portal license, no device conversion, no re-validation—open the .pd or .hmi file, verify tags, download over MPI/PROFIBUS or CF card, done. That continuity is precisely why MP370 12″ spares still move in volume a decade post-EOL.
