MTP1200 Unified Comfort is a 12.1-inch SIMATIC HMI device for WinCC Unified applications. The standard Siemens-logo article 6AV2128-3MB06-0AX1 combines a 1280 x 800 capacitive multi-touch display with industrial network, serial and USB interfaces.

The panel provides 4 GB of RAM, 32 GB internal flash and two SD-card combination slots. Its three Ethernet ports include an integrated 10/100 Mb/s two-port switch and a separate Gigabit interface for structured machine and service networks.

• Uses capacitive multi-touch input for gesture-based operator interaction.
• Separates switched 10/100 Mb/s PROFINET ports from a dedicated Gigabit Ethernet interface.
• Provides four USB 3.1 host ports for approved storage and peripheral use.
• Stores application and system data across internal flash and two removable memory-card positions.
• Supports portrait and landscape project formats with a 35-degree maximum installation inclination without external ventilation.
• Offers secure HMI communication when paired with a controller and project configured for certificate-based communication.

• Unified operator stations for machine visualization, alarm handling, recipes and production data.
• Multi-controller applications using supported SIMATIC, Modbus TCP, EtherNet/IP or other configured drivers.
• Modernization of TP1200 Comfort installations where the compatible cutout is retained and the project is migrated to WinCC Unified.
• Cabinet installations requiring separate machine and service Ethernet connections.
• Applications using web technologies, Unified runtime functions and approved HMI apps.

• The current standard Siemens-logo article 6AV2128-3MB06-0AX1 is in the PM300 active phase.
• The earlier 0AX0 hardware is a separate spare-part version; retain the complete suffix when ordering.
• MTP1200 and TP1200 Comfort use compatible mounting cutouts, but the runtime platform and project engineering differ.
• Back up the Unified project, certificates, user data, recipes and device settings before service.
• After exchange, verify the firmware image, project download, trusted controller certificates and all configured communication channels.

Which article is represented by this MTP1200 page?

It represents the current standard Siemens-logo Unified Comfort article 6AV2128-3MB06-0AX1.

Is MTP1200 a resistive-touch panel?

No. MTP1200 Unified Comfort uses a capacitive multi-touch screen.

How many Ethernet ports are available?

The panel has two switched 10/100 Mb/s RJ45 ports and one separate 10/100/1000 Mb/s RJ45 port.

Can an existing TP1200 Comfort project be downloaded unchanged?

No. The mounting cutout is compatible, but migration to the WinCC Unified platform and project validation are required.

What storage interfaces are built in?

The device provides two SD/SDHC/SDXC combination slots and four USB 3.1 Type A host ports.

What should be checked when replacing an 0AX0 device?

Confirm the complete article suffix, firmware, Unified project, certificates, mounting, interfaces and installed accessories.
