SIEMENS 6AV6545-0DA10-0AX0

What is 6AV6545-0DA10-0AX0 and where is it used?

The 6AV6545-0DA10-0AX0 is a SIEMENS SIMATIC Multi Panel MP370 12" Touch. It is an industrial HMI operator panel featuring a 12.1-inch colour TFT display, touchscreen operation, Windows CE 3.0, and engineering support via ProTool from Version 5.2 SP3 or WinCC flexible Standard from Version 2004 onwards. The panel is typically used for machine and system operation in existing installations, where visualisation, alarms, recipes and diagnostic functions continue to run on an established MP370 platform. For maintenance personnel, the exact part number is particularly important because it enables the correct identification of the appropriate panel for fault diagnosis, spare-part identification, repair approval and replacement procurement.

Overview of the key technical specifications and their significance

The panel is equipped with a resistive analogue touchscreen, a resolution of 800 × 600 pixels, a 24 V DC power supply, a typical power consumption of 28 W, and a nominal current consumption of 1.15 A. Additional features relevant for industrial applications include IP65 protection on the front panel, IP20 protection on the rear, an operating temperature range of 0 to 50 °C, and a wide range of interfaces including TTY, 2 × RS232, RS422, RS485, Ethernet RJ45 and USB, as well as PC card and CF card slots. For operators, these specifications primarily mean excellent suitability for traditional control cabinet and machine-front installations, compatibility with legacy communication environments, and continued access to established service options for older systems. The optional 3.6 V backup battery and support for a serial UPS connection provide additional protection for data and operating states in critical applications.

Product status, life-cycle status and obsolescence

The MP370 12" Touch is listed by Siemens as a spare part, while the EICHLER product page additionally specifies an EOP (End of Production) status effective from 01 August 2008. Siemens already classified the MP370 series as a phase-out product in 2008, providing a clear indication of its obsolete status. For operators, this means that purchasing new units through traditional manufacturer channels is becoming increasingly difficult, while repair services, exchange units, used-device procurement and strategic stockholding are gaining importance. Within Siemens support documentation, the MP377 12" Touch was initially identified as the successor platform, with the TP1500 Comfort subsequently referenced as a later-generation successor. In practice, however, these alternatives should not be regarded as direct one-to-one replacements. Any migration must be carefully evaluated with regard to project migration, installation requirements, communication interfaces and commissioning procedures.

Available EICHLER services and when they are relevant

For this assembly, EICHLER offers several practical options, including repair services, exchange units, used-device procurement and new-device enquiries. According to the product page, repair, exchange and used-device options are each available with typical turnaround or delivery times of 1–3 days. For repairs, EICHLER additionally provides technical cleaning, preventive maintenance, comprehensive functional testing and a minimum 24-month warranty. For obsolete HMI assemblies in particular, these services are highly valuable for maintenance and purchasing departments because downtime can often be resolved more quickly through repair or replacement than through an immediate migration project. In addition, Life Cycle Management services help address obsolescence challenges through asset assessments, risk evaluations and supply strategies, enabling operators to systematically reduce the risk of supply shortages for ageing operator panels.

Is 6AV6545-0DA10-0AX0 still available or has it already been discontinued?

The device belongs to the discontinued MP370 product generation. Siemens classified the MP370 series as a phase-out product as early as 2008, while the specific panel continues to be listed as a spare part. The EICHLER product page additionally specifies an EOP (End of Production) status effective from 01 August 2008. For operators, this primarily means that purchasing new units is no longer the standard approach. Instead, long-term availability is typically maintained through repair services, exchange units, used devices and strategic stockholding.

Which engineering software is required for the MP370 12" Touch?

The product documentation specifies ProTool from Version 5.2 SP3 or WinCC flexible Standard from Version 2004 onwards for engineering and project configuration. This is particularly important for service activities, data backup procedures and migration planning, as many legacy systems still operate on exactly this engineering platform. Anyone intending to source a replacement device or restore an existing project should first verify which project version is currently available and whether the corresponding engineering environment is still accessible.

Which communication and service interfaces are available on the panel?

The MP370 12" Touch provides 1 × TTY, 2 × RS232, 1 × RS422, 1 × RS485, 1 × Ethernet RJ45 and 1 × USB, as well as PC card and CF card slots. For maintenance personnel, these interfaces are important because they define the available options for project transfer, diagnostics, data backup and integration into legacy systems. In existing machines that combine both older and newer communication technologies, this broad range of interfaces is particularly advantageous because it allows legacy communication structures to remain in operation.

Is there a manufacturer-recommended successor for the 6AV6545-0DA10-0AX0?

Within Siemens support documentation, the MP377 12" Touch was initially identified as the direct successor platform, while the TP1500 Comfort was later referenced as the next-generation replacement concept. In practice, however, these alternatives should not be regarded as simple plug-and-play replacements. Due to the different platform generations, software environments and migration requirements, factors such as project conversion, mounting cut-out dimensions, communication interfaces and commissioning effort must be carefully assessed before a replacement is implemented.

Which power supply and environmental conditions are important for operation?

The panel requires a 24 V DC power supply, has a typical power consumption of 28 W, and is designed to operate within an ambient temperature range of 0 to 50 °C. It is rated IP65 on the front panel and IP20 on the rear. For control cabinet and machine-building applications, this means that the panel is suitable for traditional industrial installation environments, provided that the thermal conditions, vertical mounting orientation and the maximum permissible 35° installation angle without forced ventilation are observed. Before replacing the panel, it is therefore advisable to confirm that the actual environmental conditions of the system still fall within these specified limits.

When is repair more sensible than immediate migration?

A repair is usually the preferred option when the existing project must remain operational, the machine needs to be returned to service quickly, and major modifications to the visualisation, engineering environment and commissioning process should be avoided. For this device, EICHLER offers repair services, exchange units and used-device procurement with typical turnaround times of 1–3 days. The repair service includes technical cleaning, preventive maintenance, comprehensive functional testing and a minimum 24-month warranty. Where long-term obsolescence risks exist, additional Life Cycle Management measures can help transform an isolated repair requirement into a structured and sustainable supply strategy.
