What is 6AV6644-0AB01-2AX0 and where is it used?
The 6AV6644-0AB01-2AX0 is a Siemens SIMATIC MP 377 15" Touch Multi Panel used for industrial operation, visualisation, and diagnostics. It is designed for demanding HMI applications in machines and plant systems where a large touchscreen interface with stable integration into existing automation systems is required.
It typically appears in production machines, packaging lines, process plants, and retrofit projects, especially where existing HMI systems must continue operating without major mechanical or software redesign.
For maintenance and procurement teams, the exact order number is critical because the device form factor, communication interfaces, and existing project data are tightly coupled to the installed hardware base.
Overview of key technical data and what it means
The panel features a 15-inch TFT display with 65,536 colours and 1024 × 768 resolution (XGA). It uses an analog resistive touchscreen, which is suitable for industrial environments and supports calibration.
For system integration, the MP 377 offers extensive connectivity options including 2× Ethernet (RJ45), RS422, RS485, 2× USB ports, CF card slot, and MMC slot. Supported protocols include PROFINET IO, PROFIBUS, MPI, EtherNet/IP, MODBUS, and TCP/IP.
The front is rated IP65, while the rear is IP20, and the usable application memory is approximately 12 MB. In practice, this makes the device suitable for mixed legacy and modern communication architectures, which is common in long-life industrial installations.
Product status, life cycle status and obsolescence
From a lifecycle perspective, the 6AV6644-0AB01-2AX0 is already in the spare parts phase. Siemens indicates in its documentation that new delivery from factory has been blocked since 01.01.2015.
Additionally, Siemens defines a P.M490 lifecycle milestone with an end date of 01.10.2026, indicating a final phase of product support.
For migration planning, Siemens identifies the SIMATIC HMI TP1900 Comfort (6AV2124-0UC02-0AX0) as a validated successor platform.
This means that for many installed systems, the focus is no longer on new purchase, but on repair, exchange units, refurbished devices, or planned migration strategies to newer HMI generations.
Available EICHLER services and when they are relevant
For this device, EICHLER offers repair, exchange units, refurbished devices, and new units on request. Repair is especially relevant when the existing panel must remain identical in terms of mechanics, project configuration, and machine integration.
According to the service description, repairs include technical cleaning, preventive maintenance, full functional testing, and a minimum 24-month warranty. A test report can also be provided.
Exchange or refurbished units are particularly useful when downtime must be minimised and a ready-to-use replacement is required quickly.
These services are only offered for industrial customers and are designed to ensure continued operation of legacy systems even when manufacturer new supply is no longer available.

| Fault description | Possible solution |
|---|---|
| Why can I not connect to the MP 377 or transfer a project? | First check whether the panel is in transfer mode and whether transfer type, address, cable connection, connectors, and PG/PC interface are correctly configured. Siemens explicitly lists these as key checks. In addition, the OS/image version must match the engineering version used in WinCC flexible. If changes were made to the MPI/DP baud rate, the panel must be restarted. For transferring images or projects, Siemens states that the PC Adapter MPI/PROFIBUS is not approved for this purpose. |
| Why does the transfer on the MP 377 stop at around 90%? | Check the device status, the transfer setting on the panel, and the version of WinCC flexible or the installed image. In practical cases involving the MP 377, transfer failures at around 90% were resolved by aligning the WinCC flexible version and correcting the download/transfer settings. A consistent check of project version, OS level, and transfer path is the most effective first step. |
| Why does the touchscreen respond inaccurately or not at all? | Perform a touch calibration via Control Panel > OP > Touch. Siemens explicitly recommends recalibration before or after an OS update or recommissioning. For cleaning and operation, the touchscreen should only be cleaned when the system is in a locked state. If the touch is offset after a restore or OS update, recalibration is usually the first and most effective corrective action. |
| Why does backup/restore fail with “not_allow” or incompatible backup? | This message typically indicates that the backup file, OS version, and hardware configuration do not match. Verify that the backup originates from a compatible MP 377 device and that the OS version on the target device is correct. If necessary, the correct image must be loaded first before repeating the restore. The correct image path in ProSave should also be checked. |
| Why are recipes, user data, or licences missing after an OS update? | Siemens states that an OS update deletes all data on the HMI device. Therefore, users, recipes, and licences must be backed up before performing the update. For the MP 377 series, licence keys can be included in a full backup, but a dedicated licence backup is still recommended. After a restore or factory reset, the project must be downloaded again and verified. |
Is 6AV6644-0AB01-2AX0 still available as a new unit from the manufacturer?
Siemens lists the 6AV6644-0AB01-2AX0 in its current datasheet as a spare part. It is also stated that new deliveries from the factory have been blocked since 01.01.2015.
For operators this means that procurement is no longer based on standard new production supply, but typically relies on repair, exchange units, refurbished stock, or planned migration strategies. This is also reflected on the EICHLER service side, where repair, exchange, used units, and new-on-request options are provided.
Which Siemens successor is specified for the MP 377 15" Touch?
In Siemens’ official migration guidance, the TP1900 Comfort (6AV2124-0UC02-0AX0) is named as the successor platform for the MP 377 15" Touch.
For operators, this should not be seen as a simple one-to-one replacement, but as a migration path. Especially in established systems, the project structure, screen design, operating concept, and cabinet integration should be reviewed in advance to avoid unexpected commissioning risks.
Which software is required to engineer 6AV6644-0AB01-2AX0?
According to Siemens, the device can be engineered using WinCC flexible Standard from version 2007 onwards. The datasheet also references compatibility within the WinCC Comfort, WinCC Advanced, and WinCC Professional environment.
In legacy systems, the key issue is not only software availability, but ensuring consistency between engineering version, OS image, and existing project data. Version mismatches are a common cause of transfer and restore issues in older panels.
Which interfaces and protocols are most relevant in legacy installations?
The MP 377 is particularly relevant in retrofit environments because it combines multiple communication technologies in one device. Siemens specifies 2× Ethernet, RS422, RS485, USB, CF card slot, and MMC slot, along with support for PROFINET IO, PROFIBUS, MPI, EtherNet/IP, MODBUS, and TCP/IP.
This makes the panel suitable for mixed environments where legacy PLC systems and modern network infrastructure coexist.
When is repair more suitable than replacement or refurbished units?
Repair is typically the better option when the panel is mechanically and electrically compatible with the machine and the existing project must remain unchanged, allowing a fast return to operation without engineering effort.
Exchange or refurbished units are more suitable when downtime must be minimized and immediate replacement is required without troubleshooting the original device.
According to EICHLER service information, repair includes cleaning, preventive maintenance, full functional testing, and a minimum 24-month warranty. This is particularly relevant for operators aiming to reduce downtime and manage obsolescence risks in a controlled way.
What should be considered in the spare parts and obsolescence strategy?
For this device, operators should no longer rely on ad-hoc procurement. Siemens documents its spare-part status, the blocked new delivery since 01.01.2015, and a lifecycle end target (P.M490) of 01.10.2026. At the same time, the TP1900 Comfort is defined as the successor platform.
This leads to a practical strategy combining project backup, repair feasibility, short-term replacement options, and planned migration before a time-critical failure occurs.
