Siemens 6AV6371-1AE10-0AX0 SIMATIC WinCC

SKU: 6AV6371-1AE10-0AX0 Category: HMI & Display Brand: Siemens

Description
Additional information

The Siemens 6AV6371-1AE10-0AX0 is a WinCC (Windows Control Center) runtime software license belonging to Siemens' SIMATIC HMI software family. This part number corresponds to a WinCC flexible or WinCC basic/advanced runtime package used for PC-based SCADA and HMI visualization on standard industrial PCs and panel PCs. It enables the creation and execution of process visualization applications for monitoring and controlling industrial automation systems.

The WinCC runtime software supports a wide range of communication interfaces including PROFIBUS, PROFINET, MPI, and OPC UA/DA, enabling seamless integration with SIMATIC S7 PLCs and third-party controllers. It provides features such as alarm management, trend displays, recipe management, user administration, and historical data logging. The software is designed to run on Windows-based operating systems and supports scalable tag counts depending on the license tier, with this specific variant supporting a defined number of power tags for process variables.

The 6AV6371-1AE10-0AX0 is widely used in manufacturing plants, process industries, water treatment facilities, and building automation systems where PC-based HMI visualization is required. It is suitable for applications demanding centralized monitoring of multiple machines or production lines, integration with enterprise-level MES/ERP systems, and detailed process data archiving. Its compatibility with the broader SIMATIC automation ecosystem makes it a common choice for Siemens-based control architectures.

Common Error Codes and System Events

Event ID: 1000000: Runtime startup error — WinCC runtime failed to initialize correctly, often due to a missing or corrupt project file.
Verify the project file path is correct, check for file corruption, and restart the WinCC runtime service.
Event ID: 1000008: Communication error — Connection to the configured PLC or data source could not be established.
Check network cabling, verify PLC IP address or MPI/PROFIBUS address settings, and confirm the communication driver is correctly configured.
Event ID: 1000022: Tag read/write error — A process tag could not be read from or written to the connected controller.
Verify the tag address configuration in the WinCC project, check PLC program for the corresponding data block or variable, and confirm communication is active.
Event ID: 1000040: License error — A valid WinCC runtime license was not found or the tag count limit has been exceeded.
Check the installed license using the Siemens Automation License Manager (ALM), ensure the correct license is activated, and verify the number of configured power tags does not exceed the licensed limit.
Event ID: 1000051: Archive error — The data archive could not be written, possibly due to insufficient disk space or a corrupted archive database.
Check available disk space on the archive drive, verify archive path settings, and if necessary compact or back up and reset the archive database.
Event ID: 1000065: User administration error — Login failed or user rights configuration is inconsistent.
Review user group settings in the WinCC project, reset user passwords if necessary, and ensure the user administration database is not corrupted.
Event ID: 1000080: Script/VBS runtime error — A configured VBScript or C-script action encountered an execution error.
Open the WinCC Script Diagnostics tool, identify the faulty script, check for syntax errors or invalid tag references, and correct the script logic.

Frequently Asked Questions

What is the tag count supported by the 6AV6371-1AE10-0AX0 license?

The 6AV6371-1AE10-0AX0 is a WinCC runtime license with a specific power tag limit defined by the license tier. The exact tag count should be confirmed against the Siemens order documentation, as WinCC licenses are available in tiers ranging from 128 to unlimited tags.

Which PLCs are compatible with this WinCC runtime software?

This WinCC runtime is compatible with the full range of SIMATIC S7 controllers including S7-300, S7-400, S7-1200, and S7-1500 via PROFIBUS, PROFINET, or MPI. Third-party PLCs can also be connected using OPC DA/UA or available communication drivers.

Does this license include WinCC configuration/engineering software?

No, the 6AV6371-1AE10-0AX0 is a runtime license only, which allows execution of a pre-configured WinCC project. A separate WinCC engineering or configuration software license is required to create or modify projects.

On which operating systems can this WinCC runtime be installed?

WinCC runtime is designed for Windows-based operating systems, typically Windows 7 Professional or Windows 10 (64-bit) in industrial versions. Refer to the Siemens compatibility matrix for the specific OS versions supported by this release.

Is the Automation License Manager (ALM) required to manage this license?

Yes, the Siemens Automation License Manager (ALM) must be installed on the PC to activate and manage the WinCC runtime license. The ALM handles license transfer, verification, and monitoring of the installed license.

Troubleshooting

WinCC runtime fails to start and displays a license error on launch

Open the Siemens Automation License Manager (ALM) and check whether a valid WinCC runtime license is listed as active. Verify the license has not been transferred or corrupted.

If the license is missing, use the ALM to restore it from a backup or transfer it from the original license medium. Ensure the license matches the installed WinCC version and tag count configuration.

No communication between WinCC and the SIMATIC PLC after project start

Check the channel diagnostics in WinCC Tag Management to see if the communication driver reports an error. Verify the PLC IP address, subnet settings, and that the PC network adapter is correctly configured.

Correct the connection parameters in the WinCC project (IP address, rack/slot number), ensure the PLC is in RUN mode, and verify that no firewall is blocking the PROFINET or S7 communication port (TCP 102).

Historical trend data is not being recorded or archive is empty

Check the WinCC Archive Manager for error messages. Verify that the archive tags are correctly configured and that the archive path points to a drive with sufficient free disk space.

Free up disk space if necessary, verify archive configuration settings, and restart the WinCC Archive Manager service. If the archive database is corrupted, back it up and create a new archive.

Alarm display shows no alarms even though process faults are present

Verify that the alarm tags are correctly linked to the PLC data source and that the alarm limits or bit triggers are properly configured in the WinCC Alarm Editor.

Review and correct the alarm tag configuration, ensure the connected PLC tags are being read correctly, and confirm that the alarm logging service is running within the WinCC runtime environment.

WinCC runtime performance is slow or screen updates are delayed

Check CPU and RAM utilization on the industrial PC. A high number of active tags, frequent script executions, or large archive write cycles can overload the system.

Optimize the update cycles for non-critical tags, reduce script execution frequency, ensure the PC meets the minimum hardware requirements for the installed WinCC version, and check for background processes consuming system resources.
