SIEMENS 6AV6647-0AF11-3AX0

What is 6AV6647-0AF11-3AX0 and where is it used?

6AV6647-0AF11-3AX0 is the SIEMENS SIMATIC HMI KTP1000 Basic color PN, a Basic Panel featuring both key and touch operation for visualisation and operator control tasks in machines and industrial systems. The device is particularly suitable wherever operating states, alarms, simple recipes, and operator inputs need to be managed directly at the machine. Thanks to its PROFINET / Industrial Ethernet interface, the panel is well suited for a wide range of applications in manufacturing, conveyor systems, packaging, assembly lines, and retrofit projects. For maintenance personnel, the order number is important because it enables rapid identification during troubleshooting. For purchasing departments, it simplifies the procurement of a replacement unit, exchange device, used unit, or repair service without lengthy identification procedures.

Overview of the key technical specifications and what they mean

The panel operates on 24 V DC and features a 10.4-inch TFT display with a resolution of 640 × 480 pixels and 256 colours, together with 8 function keys and an analogue resistive touchscreen. In practical terms, this provides robust operation, even for simple glove or workshop applications, while offering sufficient display quality for conventional machine screens, alarms, and setpoint entry. The front is rated IP65, making it suitable for installation in control cabinet doors, while the rear is rated IP20. The PN version includes 1 Industrial Ethernet interface and supports protocols such as PROFINET, TCP/IP, DHCP, SNMP, EtherNet/IP, and Modbus TCP/IP. Typical operating values include 15 W power consumption and 0.6 A nominal current consumption. For panel builders, the 310 × 248 mm mounting cut-out and 60 mm installation depth are also important considerations.

Product status, life-cycle status, and obsolescence

For this panel, obsolescence management is a key consideration. The product record lists EOP (End of Production) with an effective date of 01 October 2022 for 6AV6647-0AF11-3AX0. Siemens had already announced the discontinuation of the 1st Generation Basic Panels in 2016, while spare-parts support is documented as extending into the period up to 2026. For operators of existing installations, this means the device remains relevant for service, spare-parts management, and migration projects, but is no longer the preferred choice for new installations. Siemens identifies the 2nd Generation Basic Panels as the successor platform, specifically the KTP900 Basic (6AV2123-2JB03-0AX0) and KTP1200 Basic (6AV2123-2MB03-0AX0). The most suitable option depends on the installation space, operating concept, and overall migration strategy.

Available EICHLER services and when they are relevant

For operators of ageing systems, technical specifications alone are not enough; the critical question is how to minimise downtime. This is where EICHLER's services become particularly relevant. For 6AV6647-0AF11-3AX0, EICHLER currently offers repair, exchange, used units, and new units on request. The product page lists short processing or delivery times of 1–3 days for repairs, exchanges, and used units. Repair services include technical cleaning, preventive maintenance, functional testing, and a minimum 24-month warranty. An optional test report is particularly valuable for purchasing departments, quality assurance teams, and maintenance organisations that require documented verification. For obsolete HMIs, these services provide a practical way to maintain functionality, traceability, and supply security, even when OEM spare parts become scarce or economically unattractive.

Is 6AV6647-0AF11-3AX0 still available, or only as a used or repairable unit?

As of 24 April 2026, the panel is still offered by EICHLER through service- and procurement-oriented channels: repair, exchange, and used units are listed with short lead times on the product page, while new units are available on request. At the same time, the model is clearly approaching obsolescence from a life-cycle perspective. For operators of existing installations, the key factor is therefore usually not the availability of a brand-new unit, but rather the combination of repairability, exchange availability, and a well-planned spare-parts strategy. This is what ultimately ensures long-term supply security.

What is the successor to Siemens 6AV6647-0AF11-3AX0?

Siemens identifies the KTP900 Basic (6AV2123-2JB03-0AX0) and the KTP1200 Basic (6AV2123-2MB03-0AX0) as the main successor options for the KTP1000 Basic color PN. This is important because there may not be a straightforward 1:1 replacement without considering the mounting cut-out, display size, project migration requirements, and operating concept. For retrofit projects, it is therefore advisable to determine which successor panel is the best fit mechanically, functionally, and economically. For systems with a limited remaining service life, however, a repaired original unit may still be the most cost-effective solution.

Which software is required for 6AV6647-0AF11-3AX0?

Siemens lists the panel as configurable with WinCC flexible 2008 SP2 Compact, WinCC Basic V10.5, and STEP 7 Basic V10.5. Current product information also indicates support through WinCC Basic, Comfort, Advanced, and Professional within the TIA Portal environment. For maintenance personnel and system integrators, this information is important because it indicates whether the existing project is still maintained in a legacy engineering environment or has already been migrated to a more recent TIA Portal version. Before making any modifications, the actual project basis used in the installation should always be verified.

Can I create a backup of the KTP1000 Basic color PN before replacement?

Yes. Siemens describes backup and restore procedures for Basic Panels using WinCC, WinCC flexible, and ProSave. Depending on the configuration, the backup can include the project, HMI image, password lists, and recipe data. This is particularly important when preparing a replacement panel, installing an exchange unit, or creating a recovery point before performing an OS update. Having a reliable backup significantly reduces the risk of losing time through unnecessary re-engineering in the event of a failure or migration.

Which PLCs and protocols are supported by the KTP1000 Basic color PN?

The panel features an Industrial Ethernet / PROFINET interface and supports, according to Siemens, protocols including PROFINET, TCP/IP, DHCP, SNMP, EtherNet/IP, and Modbus TCP/IP. For controller connectivity, Siemens lists support for S7-1200, S7-1500, S7-200, S7-300/400, LOGO!, and WinAC, as well as selected third-party systems such as Allen-Bradley via EtherNet/IP, Mitsubishi MC TCP/IP, and Modicon Modbus TCP/IP. For purchasing and technical departments, this information provides a quick indication of whether the panel can continue to be used within an existing machine architecture or serve as a practical interim solution during modernisation projects.
