SIEMENS 6AV2124-1GC01-0AX0

What is 6AV2124-1GC01-0AX0 and where is it used?

The 6AV2124-1GC01-0AX0 is the SIMATIC HMI KP700 Comfort from Siemens, a 7-inch Comfort Panel with keypad operation for machine and system monitoring and control tasks. The device is designed for visualisation, operator input, alarm handling and guided operating procedures. Thanks to PROFINET as well as MPI/PROFIBUS-DP, it fits both modern Ethernet-based topologies and existing legacy installations. Typical applications include packaging machines, conveyor systems, production lines, retrofit projects and manufacturing environments where dedicated function keys, clear operating logic and robust front-panel operation are required. In systems with standardised operating procedures, a keypad panel is often the preferred choice because functions can be assigned clearly and operated quickly.

Overview of the most important technical data and what they mean

The KP700 Comfort features a 7" TFT widescreen display with 800 × 480 pixels and 16,777,216 colours. For operation, the device provides 24 LED function keys, a numeric keypad and an alphanumeric keypad; this model does not include a touchscreen. The panel is powered by 24 V DC with a permissible range of 19.2 to 28.8 V, and its typical power consumption is 12 W. Communication interfaces include Industrial Ethernet with an integrated 2-port switch, RS422/RS485, 2 × USB 2.0 and 2 SD card slots. Additional features relevant for control cabinet installation include IP65 protection at the front, IP20 at the rear, a typical real-time clock backup of six weeks, and operation at temperatures up to 50 °C when mounted vertically in landscape orientation.

Product status, life-cycle status and obsolescence

Siemens lists the 6AV2124-1GC01-0AX0 with the life-cycle status PM400: Product phase-out announcement, with an effective date of 31 January 2026. Siemens also identifies 6AV2128-3GB06-0AX1 as the successor. However, this successor is a SIMATIC HMI MTP700 Unified Comfort Panel with touchscreen operation and engineering based on WinCC Unified Comfort V16 or later. For maintenance departments and purchasing teams, this distinction is important: the successor is officially designated by the manufacturer, but it is not necessarily a direct 1:1 replacement without verifying installation dimensions, operating concept and engineering requirements. It should also be noted that the existing device is still based on Windows CE 6.0, and according to the product description, Microsoft support and security updates for this operating system have already ended.

Available EICHLER services and when they are relevant

For the 6AV2124-1GC01-0AX0, EICHLER offers repair, exchange, used equipment and new units. The product page indicates short processing times of 1–3 days for several of these service options. This is particularly valuable in the event of an unplanned machine downtime where a complete modernisation is not yet technically or economically justified. According to EICHLER, the repair service includes technical cleaning, preventive maintenance, comprehensive functional testing and a minimum 24-month warranty; an optional test report is also available. For maintenance personnel, this reduces the risk associated with recommissioning. For purchasing departments, it provides predictable procurement routes, while decision-makers benefit from a practical way to maintain the availability of installed Comfort Panels even during an advanced stage of the product life cycle.

Is 6AV2124-1GC01-0AX0 a touchscreen panel or a keypad panel?

The 6AV2124-1GC01-0AX0 is a keypad-only panel. The device is called KP700 Comfort, operates exclusively via keys and features 24 LED function keys as well as a numeric and alphanumeric keypad. This model does not include a touchscreen. This is particularly useful in applications that rely on fixed operator stations, glove operation or clearly assigned key functions.

Which software and engineering platform are required for the KP700 Comfort?

The panel can be engineered from WinCC Comfort V11 onwards. It is also important that the device version configured in the project matches the image or runtime version installed on the panel. If an older device version is no longer directly supported in newer WinCC releases, Siemens describes a migration path in which the project is first opened in an older software version and the device or device version is adjusted there before further migration.

Is there an official successor for 6AV2124-1GC01-0AX0?

Yes. Siemens identifies 6AV2128-3GB06-0AX1 as the successor. This device belongs to the Unified Comfort Panel family, is an MTP700 with touchscreen operation and is engineered with WinCC Unified Comfort V16 or later. In practice, this means that the successor is officially designated by the manufacturer, but the operating concept, engineering environment and mechanical integration should be carefully evaluated before migration.

Can a project be transferred to the panel without a direct online connection?

Yes. Siemens also supports project transfer to Comfort Panels via a storage medium, such as a USB flash drive. This can be particularly useful when online access is unstable, remote connections are problematic or updates need to be installed in a controlled manner during planned maintenance windows. According to Siemens, this download method is supported on Comfort Panels from device version V14.0 onwards.

Is the KP700 Comfort suitable as a replacement for older OP177B or OP277 applications?

Yes. Siemens has referenced the KP700 Comfort in several migration and successor scenarios, including as a successor for the OP177B and within the context of older OP and MP panel generations. For current procurement decisions, however, it is important to note that the KP700 Comfort itself has already entered the product phase-out announcement stage. In existing installations, repair or exchange of an installed KP700 may therefore be the preferred option, while larger modernisation projects may justify a direct move to a Unified platform.

Why is repair often the most economical option for this device?

Because the panel is widely installed but has been listed with PM400 status since 31.01.2026. As a result, fast and reliable service options become increasingly valuable. EICHLER offers repair, exchange, used units and new units for this model. The repair service includes technical cleaning, preventive maintenance, functional testing and a minimum 24-month warranty. For operators, this is often the most cost-effective way to minimise downtime while allowing modernisation projects to be planned properly rather than being carried out under time pressure.
