SIEMENS 6AV6545-0DB10-0AX0

What is 6AV6545-0DB10-0AX0 and where is it used?

The 6AV6545-0DB10-0AX0 is a SIEMENS SIMATIC MP370 15" Touch Multi Panel from the MP370 product family. This operator panel is designed for machine and plant visualisation and performs typical HMI tasks such as operator control, process monitoring, alarm handling, recipe management and data archiving. According to the product data sheet, the panel operates with Windows CE 3.0 and can be engineered using ProTool from Version 6.0 SP2 onwards or WinCC flexible Standard from Version 2004 onwards. In existing installations, the device is particularly relevant where an existing visualisation system must continue operating and a replacement panel is required without extensive modifications to the control cabinet or engineering environment.

Overview of the key technical specifications and their significance

The panel features a 15.1-inch TFT colour display with 256 colours and a resolution of 1,024 × 768 pixels. This XGA resolution is well suited to older but detailed process screens containing clear-text alarms, recipe interfaces and archive displays. Operation is performed via an analogue resistive touchscreen. The device is powered by 24 V DC, with a typical power consumption of 41 W and a rated current consumption of 1.8 A. For integration into existing installations, the communication interfaces are particularly important: 1 × TTY, 2 × RS232, 1 × RS422, 1 × RS485, 1 × Ethernet (RJ45), 1 × USB, plus PC Card and CompactFlash card slots. The protection rating is specified as IP65 on the front panel and IP20 on the rear, while the permitted operating temperature range is 0 to 50 °C.

Product status, life-cycle status and obsolescence status

For purchasing and maintenance departments, the life-cycle status is a key consideration. Siemens most recently classified the 6AV6545-0DB10-0AX0 as a spare part, while the SIMATIC MP370 product family has been officially designated as a discontinued series. For the MP370 15" Touch, Siemens identifies the MP377 15" Touch as the compatible successor device and specifies the MLFB 6AV6644-0AB01-2AX0 within its support documentation. For operators, this means that supply availability can no longer be compared to that of an actively manufactured product. As a result, repair services, tested exchange units and planned modernisation strategies become increasingly important in order to avoid procurement difficulties during unplanned downtime.

Available EICHLER services and when they are relevant

For this panel, EICHLER offers repair services, exchange units and tested used devices. For an obsolete HMI assembly, these options are particularly relevant for maintenance and procurement teams. A repair is often the preferred solution when the existing project configuration, installation location and machine approval status should remain unchanged. An exchange unit is advantageous when production downtime must be minimised immediately. A tested used device is frequently the most practical option when a machine is expected to remain in operation for several more years but a complete retrofit project has not yet been planned. For repairs, EICHLER specifies technical cleaning, preventive maintenance, comprehensive functional testing and a minimum 24-month warranty. In addition, a test report can be selected as an optional service.

Is 6AV6545-0DB10-0AX0 still regularly available?

Not in the sense of a current production product. Siemens continues to list the 6AV6545-0DB10-0AX0 as a spare part, while the MP370 product family has been designated as a discontinued series. In practical procurement terms, this means that the key factors are tested stock availability, exchange units, repair options and a reliable modernisation strategy. For critical installations, it is therefore important to evaluate not only current availability but also medium-term supply security.

Which software is required for the 6AV6545-0DB10-0AX0?

For this panel, Siemens specifies ProTool from Version 6 SP2 onwards or WinCC flexible Standard from Version 2004 onwards. This is particularly important for service and spare-parts procurement because it determines whether an existing project can be maintained, backed up or transferred to another device at short notice. Before sourcing a replacement, it should therefore be clarified which engineering platform and software version are actually being used on the existing panel.

Which Siemens successor is suitable for the MP370 15" Touch?

Siemens identifies the MP377 15" Touch as the compatible successor to the MP370 15" Touch. Within Siemens product support documentation, this device is referenced under MLFB 6AV6644-0AB01-2AX0. This information is particularly relevant for decision-makers when a repair is no longer considered economical or when a planned technology upgrade is being prepared. Nevertheless, any replacement should be assessed not only from a mechanical perspective but also with regard to project compatibility and communication interfaces.

Can I migrate an old backup to a new panel without the original project source?

This depends largely on the type of runtime environment available on the original device. Siemens provides migration services for obsolete HMIs and continues to support the MP370 and MP377 device families within its legacy product portfolio. However, current Siemens documentation also states that ProTool runtime files (.fwd) are not supported for backup conversion, whereas WinCC flexible projects and backups may be convertible. Before starting a retrofit project, it is therefore essential to determine whether the existing panel is running ProTool or WinCC flexible.

Which interfaces are particularly important on the 6AV6545-0DB10-0AX0 for existing installations?

The most important interfaces are Ethernet, USB, RS232, RS422 and RS485, together with support for transfer operations via MPI/PROFIBUS DP. The device additionally includes PC Card and CompactFlash card slots. For maintenance personnel, these interfaces are critical because they determine how backups, project transfers, diagnostics and integration into existing control architectures can be managed. In many older installations, the available interface configuration is the deciding factor in whether a one-to-one continuation of operation is feasible or whether a modernisation project becomes the more economical option.

When is repairing an MP370 15" more economical than carrying out a system upgrade?

A repair is particularly advantageous when the existing visualisation system, panel cut-out and machine approval status should remain unchanged and downtime must be kept to a minimum. In stable legacy installations, this is often more economical than an immediate migration to a newer HMI platform. According to the EICHLER product page, repair services, exchange units and tested used devices are available for this panel. The repair service includes technical cleaning, preventive maintenance, comprehensive functional testing and a minimum 24-month warranty, helping operators maintain reliable operation while postponing larger modernisation projects until a more suitable time.
