SIEMENS 6AV6545-0CC10-0AX0

What is 6AV6545-0CC10-0AX0 and where is it used?

The 6AV6545-0CC10-0AX0 is a SIEMENS SIMATIC TP270 10" Touch Panel from the HMI product family, designed for the operation, monitoring and diagnostics of machines and systems. The operator device was developed for existing installations where visualisation, recipe management, alarm display and operator input are required directly at the machine. Typical application areas include packaging machinery, conveying technology, special-purpose machinery, process stations and retrofit projects, where an existing TP270 must be replaced or repaired while maintaining full functionality. For maintenance personnel, the exact part number is important because the project configuration, interface layout and mechanical installation are often fixed within existing systems, and using a different panel may result in additional migration effort.

Overview of the key technical specifications and their significance

The TP270 features a 10.4-inch CSTN/STN colour display with a resolution of 640 × 480 pixels (VGA) and 256 colours. For industrial operation, this provides a robust and well-established visualisation platform for traditional WinCC flexible and ProTool projects. The 2 MB project memory is typical of this generation of devices and is an important factor when assessing whether existing legacy projects can continue to be used without modification. The panel operates with Microsoft Windows CE, offers IP65 protection on the front panel, and supports communication and data transfer via RS422/RS485/MPI/PROFIBUS DP, RS232 and USB. The TP270 does not include an integrated Ethernet interface; however, a compatible CF Ethernet solution was available when Ethernet connectivity was required. For purchasing departments and technical teams, these specifications are critical when compatibility, installation requirements and recommissioning effort need to be assessed quickly.

Product status, life-cycle status and obsolescence information

The device is listed by Siemens as a spare part, while the EICHLER product page additionally shows an EOP (End of Production) status effective from 01 April 2008. For operators of older systems, this is a clear indication that the TP270 belongs to a discontinued product generation and should no longer be considered a standard choice for new projects. This is precisely why a reliable spare-parts supply remains important for existing installations. In its discontinuation notice for the TP270, OP270 and MP270 series, Siemens identified the MP277 10" Touch (Order No. 6AV6643-0CD01-1AX1) as the recommended migration path for new applications. For existing systems, however, maintaining the original 6AV6545-0CC10-0AX0 is often the more economical solution, as the project, mounting cut-out and service concept can remain unchanged.

Available EICHLER services and when they are relevant

For maintenance and purchasing departments dealing with a failed or ageing TP270, four options are typically most relevant: repair, exchange unit, used assembly and new assembly. EICHLER offers all of these options for this part number, each with short turnaround or delivery times, and an optional test report is also available. This is particularly valuable when downtime must be minimised, standardisation across multiple machines is required, or internal approval processes need documented evidence. For operators of obsolete HMI technology, these services provide valuable planning security. A repair can preserve the existing project environment, an exchange unit can accelerate the return to production, used assemblies can support budget-sensitive projects, and new stock units can be used to strategically secure critical systems. In this way, operational reliability can be maintained more effectively despite the challenges of obsolescence.

Is 6AV6545-0CC10-0AX0 still suitable for new installations?

For new installations, this panel is only of limited suitability, as Siemens has discontinued the TP270 product range and now lists the device as a spare part. For existing systems, however, the assembly remains highly relevant when a panel with the same mounting cut-out, identical project basis and established communication interfaces needs to be replaced. In such situations, repair, exchange units or strategic spare-parts stockholding are often more economical than a complete HMI migration.

Which successor device does Siemens recommend for the TP270 10-inch panel?

In the discontinuation notice for the affected product family, Siemens identifies the MP277 10" Touch with Order No. 6AV6643-0CD01-1AX1 as the recommended successor and migration path for new applications. This is particularly relevant for purchasing departments when maintaining the existing visualisation unchanged is not a requirement. For maintenance personnel, however, it is important to understand that a successor panel cannot automatically be installed without migration effort, as the project configuration, communication setup and mechanical constraints must first be evaluated.

Which software can be used to configure the 6AV6545-0CC10-0AX0?

This device supports configuration using ProTool as well as WinCC flexible. The product information specifies ProTool Version 6 or later, while supplementary documentation references WinCC flexible Standard from Version 2004 onwards. Siemens documentation relating to this device family also explicitly describes the TP270 within the context of WinCC flexible 2004. This is particularly important for service applications, as legacy projects can often only be edited reliably using the original engineering environment.

Does the TP270 have an integrated Ethernet interface?

No. The TP270 does not include an integrated onboard Ethernet interface. Siemens states that Ethernet connectivity for the OP270/TP270 series could only be achieved using a NE2000-compatible CF Ethernet card. In practice, this means that anyone replacing an existing device or securing a project should not automatically assume Ethernet connectivity is available. Existing communication and transfer methods such as MPI/PROFIBUS, RS232 or USB should always be verified first.

Can a ProSave backup be restored to a replacement panel?

Yes. Siemens describes the use of ProSave backup and restore functions for Windows-based panels. The backup is stored as a .psb file and can later be restored using the Restore function. The key requirement is that the replacement device belongs to the same panel class or device type. For operators of critical systems, this is particularly valuable because a valid backup can significantly accelerate replacement and recommissioning. Without a reliable backup, the effort required for recommissioning and project reconstruction increases considerably.

Can an existing ProTool project be migrated to WinCC flexible?

Yes, in principle. Siemens explicitly describes the migration of existing ProTool projects to WinCC flexible within its migration documentation. If only archived project files or uploaded project data are available, the correct procedure involving the appropriate ProTool environment and proper unpacking or upload processes must be followed. For operators of older TP270 systems, this is an important consideration because it helps secure serviceability, documentation and future modification options without requiring an immediate complete redevelopment of the existing visualisation.

Is repair or replacement the better option for a faulty TP270?

The answer depends primarily on downtime pressure, project availability and the spare-parts situation. If the existing project is available and the device is mechanically integrated into the system without issues, repair is often the fastest way to preserve the current visualisation environment. If production must resume immediately, an exchange assembly is generally the lower-risk solution. Since Siemens now supplies the device only as a spare part, tested used units and exchange solutions are becoming increasingly important for many operators. Evaluating not only the hardware cost but also the downtime risk, migration effort and long-term support strategy is essential when determining the most economical option.
