SIEMENS 6AV6545-0BB15-2AX0

What is 6AV6545-0BB15-2AX0 and where is it used?

6AV6545-0BB15-2AX0 is a SIEMENS SIMATIC HMI TP 170B Mono touch panel designed for operating and monitoring machines and systems. The device features a 5.7-inch STN display with 4 blue-grey shades and is intended for classic HMI tasks such as entering setpoints, displaying alarms, visualising operating states and providing simple operator screens during production. Thanks to MPI/PROFIBUS-DP and additional serial interfaces, the panel is particularly suitable for existing installations where older SIMATIC architectures remain in operation. Typical applications include retrofit projects, spare-parts scenarios in maintenance environments and safeguarding production lines where the existing operating concept should be retained with minimal modification.

Overview of the key technical data and what they mean

The TP170B Mono features a resolution of 320 × 240 pixels, an analogue resistive touchscreen, a rated current consumption of 0.25 A and a typical power consumption of 6 W. For users, this means reliable operation for traditional machine screens, although it is not designed as a modern high-end graphics panel. Particularly important for replacement purposes are the available interfaces and bus systems: optional TTY, 2 × RS232, 1 × RS422, 1 × RS485 up to 12 Mbit/s, as well as a CF card slot. The front panel is rated IP65, while the rear is rated IP20. The device uses Windows CE as its pre-installed operating system and, according to the product data, can be engineered with ProTool/Lite from Version 5.2 SP1 or WinCC flexible Compact from Version 2004. Siemens documentation also specifies a 24 V DC power supply. For purchasing and technical departments, these factors are critical because they determine electrical compatibility, project retention and installation suitability.

Product status, life-cycle status and obsolescence

For 6AV6545-0BB15-2AX0, the EICHLER product page lists a product status of EOP: 2008-04-01. Siemens also identifies the device as a spare part in search results and indicates in product status notifications that the TP170 series has been discontinued. For operators, this means that the panel clearly falls into the category of obsolescence management and installed-base support. Anyone intending to continue operating a system with this operator panel should secure not only the part number but also the project status, interface configuration, image version and spare-parts strategy. Siemens references successor generations within later panel families for the discontinued TP170 range; however, a direct 1:1 drop-in replacement should not be assumed for this specific order number. Before replacement, project migration requirements, communication paths and software versions should always be verified.

Available EICHLER services and when they are relevant

For this panel, EICHLER offers repair, exchange, used equipment and new equipment as service options. The repair service is listed with a turnaround time of 1–3 days and includes technical cleaning, preventive maintenance, comprehensive functional testing and a minimum 24-month warranty. In addition, the shop information highlights up to 36 months warranty and guarantee, fully tested assemblies and 24/7 service. This is particularly relevant when production downtime is costly, migration is currently not feasible, or an original device is required at short notice. From a maintenance and purchasing perspective, these services provide a practical bridge between obsolescence and continued system availability: instead of relying on uncertain remaining stock, operational reliability can be maintained through repair, exchange or tested replacement units.

Which software can be used to engineer 6AV6545-0BB15-2AX0?

The panel is designed for ProTool/Lite from Version 5.2 SP1 and WinCC flexible Compact from Version 2004. For existing installations, this point is particularly important because an existing project can only be reused or migrated properly if the engineering version, image version and operator panel version are compatible. For retrofit or spare-parts projects, not only the panel itself but also the engineering environment should always be taken into consideration.

What power supply and protection rating does the TP170B require?

The device operates on 24 V DC and is rated IP65 at the front and IP20 at the rear. In practice, this means that the front is suitable for installation in machine fronts or control cabinets with appropriate sealing, while the rear requires a protected installation environment. Especially when sourcing a replacement, not only the part number but also the installation situation, front sealing and the existing 24 V supply should be checked.

Which interfaces should I check before ordering or replacing the device?

Before placing an order, at least the MPI/PROFIBUS-DP connection, the serial interfaces and the required transfer path should be verified. For the TP170B, optional TTY, 2 × RS232, 1 × RS422 and 1 × RS485 are specified. In practice, these interface configurations determine whether an existing project can continue to operate without modification or whether cables, adapters, addressing and transfer parameters must be adjusted. For purchasing and engineering departments, this is often the most important factor in avoiding incorrect orders and unnecessary downtime.

What can I use the CF card slot on the TP170B for?

The CF card slot is not only used as storage media but also for backup and restore operations. Siemens describes that data can be transferred between the memory card and the operator panel using the BACKUP and RESTORE functions. For operators of older systems, this is particularly valuable because it allows project versions to be secured, recovery procedures to be prepared and installed equipment to be protected more effectively. It is important not to remove the memory card while data is being accessed, as this may result in data loss.

Is 6AV6545-0BB15-2AX0 still a current product?

No. The available sources clearly indicate that this is a discontinued and obsolete product. The EICHLER product page lists EOP: 2008-04-01, and Siemens references the device as a spare part within the product lifecycle context. For users, this means that the panel should primarily be considered from the perspective of installed-base support, repairability, replacement options and supply security rather than as a current product generation.

When is repair more suitable than replacement or purchasing another unit?

Repair is particularly worthwhile when the existing panel fits the machine mechanically and functionally, the project is to be retained and the system must be returned to service quickly. For this device, EICHLER specifies a repair turnaround time of 1–3 days and includes technical cleaning, preventive maintenance, comprehensive functional testing and a minimum 24-month warranty. If, on the other hand, several devices are already failing, no project source is available or a complete spare-parts pool is being established, replacement or a tested spare unit may be the more economical option.

Is a newer panel automatically a direct 1:1 replacement?

This should not be assumed. Siemens identifies the TP170 series as discontinued and refers to later successor generations. At the same time, manuals and practical experience show that the image version, operating system, communication path and project version must all match correctly. Therefore, any replacement strategy should include verification of whether a functionally identical replacement is actually possible or whether project migration will be required.
