The Siemens 6AV2124-0MC01-0AX0 is a HMI TP1200 Comfort for industrial control and automation applications.

What the Siemens 6AV2124-0MC01-0AX0 Delivers

The Siemens 6AV2124-0MC01-0AX0 is a SIMATIC HMI TP1200 Comfort panel with a 12.1 in widescreen TFT display and analog-resistive touch operation. It runs on 24 V DC and draws a typical active power of 20 W, making it a practical fit for control cabinets where supply capacity is already committed.

This HMI touchscreen replacement is built for demanding environments. Its aluminum front, IP65 front protection and 0 °C to 50 °C vertical operating range suit panel builders and maintenance teams working in oil, gas and process plants. The unit carries marine approvals from ABS, BV, DNV, GL, LRS and Class NK, so it can serve both onshore and vessel-based installations.

Key Features and Technical Specifications

• Display: 12.1 in TFT widescreen with 1280 x 800 pixel resolution and 16 777 216 colors.
• Touch operation: Analog-resistive touch screen with onscreen numeric and alphanumeric keyboards.
• Supply voltage: 24 V DC rated, with a permissible range of 19.2 V to 28.8 V DC.
• Current and power: 0.85 A rated current consumption and 20 W typical active power input.
• Operating temperature: 0 °C to 50 °C for vertical installation; 0 °C to 40 °C at maximum tilt angle.
• Interfaces: One industrial Ethernet interface with two switch ports, one RS 422/485 combined port and two USB 2.0 ports.
• Protocols: PROFINET, PROFIBUS, EtherNet/IP, MPI and Modbus.
• Memory: 12 MB configuration memory, two SD card slots and recipe memory expandable via memory card.
• Protection: IP65 at the front and IP20 at the rear, with NEMA Type 4 and 4x front ratings.
• Approvals: CE, cULus, RCM and KC, plus ATEX Zone 2/22 and IECEx Zone 2/22 for hazardous areas.

The backlight MTBF of 80 000 h at 25 °C is a useful benchmark for maintenance planning. Because the backlight is dimmable from 0 to 100 %, operators can extend service life in continuously lit control rooms.

How to Evaluate This Panel Against Your Application

Start with the electrical envelope. The 24 V DC supply and 0.85 A rated current mean the panel fits standard control power budgets. Confirm that your cabinet supply stays within the 19.2 V to 28.8 V DC permissible range under load, because dips below that band can interrupt the display during startup.

Next, check the thermal margin. Vertical installation allows 0 °C to 50 °C, but portrait orientation or maximum tilt reduces the upper limit to 40 °C or 35 °C. In hot process areas, mount the panel vertically and leave clearance around the rear IP20 enclosure.

Then review the communication fit. The integrated two-port switch supports PROFINET and EtherNet/IP, while the RS 422/485 port covers MPI and PROFIBUS DP. Process coupling is listed for S7-1200, S7-1500, S7-200, S7-300/400, LOGO!, WinAC, SINUMERIK and SIMOTION, plus Allen Bradley EtherNet/IP and Modicon Modbus TCP/IP.

Finally, confirm the physical cutout. The front measures 330 mm wide by 241 mm high, the mounting cutout is 310 mm by 221 mm, and the overall depth is 64 mm. The unit weighs 2.8 kg without packaging.

Where This HMI Fits in Oil and Gas Operations

Panel builders specify this TP1200 Comfort where a 12-inch widescreen gives operators enough room for trend views, alarm views and recipe screens at once. The 1280 x 800 pixel resolution supports dense process graphics without crowding.

Maintenance teams use it as an HMI touchscreen replacement when a legacy panel loses its backlight or touch response. The 12 MB configuration memory and WinCC Comfort V11 compatibility keep existing projects portable.

Because the panel holds ATEX Zone 2/22 and IECEx Zone 2/22 approvals, it can be installed in classified areas when the enclosure design supports that rating. Marine approvals extend the same panel to offshore vessels and rigs.

Installation and Commissioning Notes

Mount the panel vertically in the cutout and secure it before applying 24 V DC. Verify polarity and confirm the supply remains inside the permissible range during startup, since the inrush current is rated at 0.5 A²·s.

For network integration, connect PROFINET or EtherNet/IP through the integrated switch ports. When wiring into a plant fieldbus, confirm cable types and any gateway or connection module with your supplier before commissioning.

Configuration is performed in WinCC Comfort, WinCC Advanced or WinCC Professional from V11 onward. The panel also supports backup and restore, both manually and automatically, which simplifies spare-unit staging.

Reliability and Maintenance Planning

Inspect the front gasket and touch surface periodically, and follow the manufacturer's safety manual for any work in hazardous areas. The dimmable backlight lets you reduce brightness in steady-state operation, which supports the 80 000 h MTBF figure at 25 °C.

Keep spare SD and Multi Media Cards on hand for recipe and archive storage. The panel accepts SD cards up to 2 GB and Multi Media Cards up to 128 MB.
