SIEMENS 6AV2125-2GB23-0AX0

What is the 6AV2125-2GB23-0AX0 and where is it used?

The 6AV2125-2GB23-0AX0 is the SIMATIC HMI KTP700F Mobile from Siemens, a mobile operator panel designed for machines and systems where operators need to control, monitor and acknowledge processes directly at the machine rather than solely from a control cabinet. The panel combines a 7-inch touchscreen with 8 function keys and also integrates safety-related operating elements such as an emergency stop/stop button, enabling switch and key switch. This makes it particularly suitable for set-up operation, service, diagnostics, manual jogging functions and mobile operating concepts on linked production systems, machining centres or robotic cells. Communication is provided via PROFINET / Industrial Ethernet.

Overview of the key technical specifications and what they mean

The panel features a 7.0-inch TFT widescreen display with a resolution of 800 × 480 pixels and 16.7 million colours. For maintenance personnel, this means good readability of operating screens, alarms and diagnostic information. The combination of touch operation and 8 LED function keys is advantageous where both menu-driven input and clearly assigned machine functions are required.

Other important technical features include 1× PROFINET, 1× USB 2.0 and 1× SD card slot. The device is powered by 24 V DC, has a typical power consumption of 8.5 W, and is rated IP65 on all sides, making it suitable for industrial environments. For safety applications, it supports PROFIsafe and achieves Performance Level e (PLe) according to ISO 13849-1 and SIL 3 according to IEC 61508.

Product status, life-cycle status and obsolescence status

For purchasing, maintenance and life-cycle planning, it is important that the 6AV2125-2GB23-0AX0 is currently listed in Siemens product documentation as an Active Product and belongs to the Mobile Panels 2nd Generation family. As a result, the device is not currently classified as discontinued or obsolete. There is therefore no officially designated successor that needs to be considered at present.

For operators, this is significant because standardisation, new procurement and spare-parts strategies based on existing TIA Portal and PROFINET infrastructures remain a viable long-term approach. At the same time, a mobile safety HMI remains a critical component. Where downtime costs, shift operation or longer procurement lead times are a concern, a proactive repair and spare-parts strategy is still recommended.

Available EICHLER services and when they are relevant in practice

For the 6AV2125-2GB23-0AX0, EICHLER offers repair, exchange, used units and new units. Repair is particularly suitable when the existing panel fits the machine mechanically, the current project configuration should be retained, and migration to a different HMI platform is to be avoided. EICHLER's repair service includes technical cleaning, preventive maintenance, comprehensive functional testing and a minimum 24-month warranty.

An exchange service is the preferred option when downtime must be kept to an absolute minimum. Used units can be attractive for spare-parts stocking and cost control. New units are the right choice where a standardised and predictable supply strategy is required for ongoing machine production. Particularly for safety-related mobile panels, these options help ensure long-term operational reliability and availability.

Which software do I need for the 6AV2125-2GB23-0AX0?

According to the product description, the device is supported from WinCC Comfort V13 SP1 onwards. In the Mobile Panels 2nd Generation release documentation, Siemens specifies TIA Portal V13 SP1 Update 3 or later as the engineering platform. The technical data additionally lists support for WinCC Comfort, WinCC Advanced and WinCC Professional. For existing installations, it is therefore important to compare the available TIA Portal version with the actual device generation and project version in use.

Does the 6AV2125-2GB23-0AX0 support PROFIsafe?

Yes. The KTP700F Mobile supports both PROFINET IO and PROFIsafe. This makes the device particularly suitable for mobile operator stations with safety-related functions, as the emergency stop and enabling switch can be integrated into appropriate F-safety concepts. According to Siemens, the device can achieve PLe according to ISO 13849-1 and SIL 3 according to IEC 61508 in safety applications. For machine builders and retrofit projects, this is a significant advantage when safety and mobile operation need to be combined in a single device.

Which connection boxes are compatible with the 6AV2125-2GB23-0AX0?

Siemens lists the Connection Box compact, Connection Box standard and Connection Box advanced as compatible system components for the KTP700F Mobile. Where the panel is to be integrated into an existing safety concept, the Connection Box advanced is particularly relevant because it is used in Siemens safety application examples. For procurement, it is therefore important to consider not only the panel part number but also the exact connection box variant and the appropriate connection cable.

Is the 6AV2125-2GB23-0AX0 still active or already discontinued?

According to currently available Siemens product information, the 6AV2125-2GB23-0AX0 is listed as an Active Product. This is an important consideration for purchasing and maintenance departments, as there is currently no indication of an imminent discontinuation. However, operators should not ignore spare-parts planning. As with any mobile safety HMI, a proactive repair or replacement strategy remains advisable because a failure can directly affect machine availability and operability.

Is the device suitable for harsh industrial environments?

Yes. The device is specifically designed for industrial use. Siemens specifies IP65 protection on all sides, an operating temperature range of 0 to 45 °C, up to 90% relative humidity during operation, and a maximum drop height of 1.2 m. It is also classified for industrial environments according to EN 55011. In practice, this means the panel is intended for typical production environments, set-up operations and mobile service applications, provided the specified environmental limits are observed.

Which procurement or service option is most appropriate in the event of a failure?

The most suitable option depends on the failure scenario. Repair is generally the most economical choice when the existing device matches the machine and the fault can clearly be attributed to the panel itself. Exchange is the preferred option when production must resume as quickly as possible. Used units are often attractive for spare-parts stockholding or for supporting older machines economically. New units are typically the best choice for standardisation projects, serial machine production or planned upgrades. EICHLER offers all four options for this device, allowing technical, commercial and time-related requirements to be balanced accordingly.
