SIEMENS 6AV2124-0JC01-0AX0

What is the 6AV2124-0JC01-0AX0 and where is it used

The 6AV2124-0JC01-0AX0 is the SIMATIC HMI TP900 Comfort from Siemens, a 9-inch Comfort Panel for machine-level visualisation and operation in industrial systems. The device is designed for more demanding HMI applications where operators need to view process values, acknowledge alarms, modify parameters or use recipes. This panel is particularly relevant in existing installations because it combines PROFINET and MPI/PROFIBUS-DP, making it suitable for both modern and legacy Siemens environments. The device can be configured from WinCC Comfort V11 onwards, which is a key factor for retrofit projects, spare parts procurement and replacement planning. For maintenance personnel and purchasing departments, the exact article number is important because it uniquely defines the display size, communication interfaces and installation dimensions.

Overview of the most important technical data and what they mean

The TP900 Comfort features a 9-inch TFT widescreen display with 800 × 480 pixels and 16.7 million colours. For control cabinet applications, this provides clear visualisation of typical machine and process screens. The analogue resistive touch interface is designed for conventional industrial applications. Electrically, the panel requires 24 V DC with a permissible range of 19.2 to 28.8 V; typical power consumption is 18 W. Communication interfaces include Industrial Ethernet with integrated 2-port switch, RS422/RS485 for MPI/PROFIBUS-DP, 2 × USB 2.0 and 2 SD card slots. Additional specifications include IP65 protection at the front, IP20 at the rear, an installation depth of 62.7 mm and a panel cut-out of 251 × 166 mm. These characteristics are particularly important for replacement projects, wiring requirements and mechanical compatibility.

Product status, life-cycle status and obsolescence

For the 6AV2124-0JC01-0AX0, Siemens currently lists the product status PM400: Product phase-out announcement, with an effective date of 31 January 2026. For operators, this means that the panel is still clearly identifiable and widely available through service and spare-parts channels, but from a life-cycle perspective it is already moving towards obsolescence management. Siemens also identifies 6AV2128-3KB06-0AX1 as a successor reference. In Siemens documentation, this device is positioned as the MTP1000 Unified Comfort within modernisation concepts for the TP900 Comfort. For purchasers and decision-makers, this is important because successor selection involves not only availability but also project migration, communication interfaces and the overall modernisation effort.

Available EICHLER services and when they are relevant

For the 6AV2124-0JC01-0AX0, EICHLER offers repair, replacement, used equipment and new equipment. In active production environments, this is particularly important because a 1:1 replacement or a professionally executed repair often restores availability more quickly than a complete modernisation project. The repair service includes technical cleaning, preventive maintenance, comprehensive functional testing and a minimum 24-month warranty; an optional test report is also available. This is especially relevant for maintenance teams when the existing panel cut-out, project status and communication setup are to remain unchanged. For purchasing departments and production managers, the combination of repair and replacement options helps reduce the risk of extended downtime, particularly when a product has already entered its phase-out stage. These services are intended for business customers.

Is the 6AV2124-0JC01-0AX0 already discontinued?

Siemens currently lists the device with the life-cycle status PM400: Product phase-out announcement. Siemens specifies 31 January 2026 as the effective date. For procurement, this does not automatically mean that no material is available anymore, but supply should be planned proactively. It is precisely during this phase that repairs, replacement units, used assemblies and clearly defined spare-part strategies become particularly important in order to avoid unplanned system downtime.

Which successor is specified for the 6AV2124-0JC01-0AX0?

Siemens identifies 6AV2128-3KB06-0AX1 as the successor reference for the TP900 Comfort. In Siemens modernisation documentation, this device is positioned as the MTP1000 Unified Comfort within the successor context of the TP900 Comfort. For migration projects, it is important not to focus solely on the article number, but also to evaluate project migration, the visualisation concept and the mechanical integration. A successor is therefore not automatically a completely seamless 1:1 replacement but rather part of a structured modernisation assessment.

Which software can be used to configure the TP900 Comfort?

The 6AV2124-0JC01-0AX0 can be configured from WinCC Comfort V11 onwards. This information is particularly relevant for maintenance and engineering teams when an existing project needs to be reloaded, extended or checked for compatibility. It should also be noted that the panel is based on Windows CE 6.0. For operators of older machinery, this combination is typical, but it also indicates that existing installations should be carefully assessed when modifications or cybersecurity considerations are involved.

Which interfaces are particularly important when replacing the panel?

For replacement projects in existing installations, the communication and power-supply specifications are especially important. The panel provides PROFINET via Industrial Ethernet with an integrated 2-port switch, MPI/PROFIBUS-DP via the combined RS422/485 interface, as well as 2 × USB 2.0 and 2 SD card slots. The device operates on 24 V DC, with a permissible range of 19.2 to 28.8 V. This combination makes the panel particularly attractive in systems where legacy fieldbus structures and newer Ethernet-based communication coexist.

Can I restore a backup to another panel?

Yes, but only under specific conditions. Siemens describes the backup/restore and automatic service concept in such a way that restoration is intended for the original device or for an operator panel of the same type. For operators, this is a critical point: a backup is extremely valuable, but it does not eliminate the need to verify exact hardware compatibility. Anyone aiming to minimise downtime should therefore plan for an identical replacement panel or an appropriate spare-part strategy.

Can I retrieve the original project from a running TP900 Comfort?

A backup secures the device data required for operation, but it is not the same as a fully editable engineering project. Siemens points out that HMI runtime data cannot simply be loaded back into a TIA Portal or WinCC project and then edited normally. For modifications, expansions or migrations, the original project remains essential. Nevertheless, backup/restore remains indispensable for ensuring a fast recovery in the event of a fault.

When is a repair more appropriate than a complete replacement?

Repair is particularly advantageous when the panel cut-out, wiring, existing WinCC project and machine approval should remain unchanged. For this panel, EICHLER offers repairs including technical cleaning, preventive maintenance, comprehensive functional testing and a minimum 24-month warranty. This is especially attractive for existing production systems because the current integration remains intact and recommissioning can often be organised more quickly than a complete modernisation project. In addition, replacement, used-equipment and new-equipment options are available.
