Siemens 6AV6371-1HQ10-0AX0 SIMATIC WinCC

SKU: 6AV6371-1HQ10-0AX0 Category: HMI & Display Brand: Siemens

Description
Additional information

The Siemens 6AV6371-1HQ10-0AX0 is a software license for SIMATIC WinCC, Siemens' professional SCADA and HMI runtime software platform. This part number corresponds to a WinCC Runtime license within the SIMATIC WinCC V7 family, designed to provide supervisory control and data acquisition capabilities for industrial process visualization on standard PC-based hardware. It enables operators to monitor, control, and log process data from connected automation systems.

SIMATIC WinCC offers a comprehensive set of features including process visualization, alarm management, trend displays, and historical data archiving. The software supports a wide range of communication interfaces including PROFIBUS, PROFINET, MPI, and OPC UA, enabling seamless integration with Siemens S7 PLCs and third-party controllers. It provides a scalable architecture supporting single-user and multi-user configurations, with robust scripting capabilities via VBScript and C-Script for custom automation logic and reporting.

SIMATIC WinCC is widely deployed in process industries such as chemical, pharmaceutical, water treatment, and power generation, as well as in discrete manufacturing environments including automotive and machine building. Its compatibility with the broader Siemens TIA Portal ecosystem and support for redundant server configurations makes it suitable for applications requiring high availability and continuous process monitoring. The software is also used in infrastructure projects such as building automation and transportation systems.

Common Error Codes and System Events

Event ID: 1000000: WinCC Runtime startup error — the runtime could not be started due to a configuration or licensing issue.
Check that a valid license is installed using the Siemens License Manager (SIMATIC Automation License Manager). Verify the project configuration for errors before restarting runtime.
Event ID: 1001: Communication error to PLC — WinCC cannot establish or maintain a connection to the configured PLC channel.
Verify network connectivity, check channel driver configuration, confirm PLC IP address or MPI/PROFIBUS address settings, and ensure the PLC is in RUN mode.
Event ID: 2000: Archive database error — the process value or alarm archive database is unavailable or corrupted.
Check SQL Server service status, verify database file integrity, and if necessary restore the archive from a backup or reinitialize the archive.
Event ID: 10000: License not found — no valid WinCC Runtime license detected on this system.
Install the correct WinCC Runtime license using the SIMATIC Automation License Manager. Ensure the license matches the configured power tag count.
Event ID: 3000: Tag logging overflow — the process value archive buffer has overflowed due to high data volume or slow storage.
Reduce the logging cycle time, optimize the number of archived tags, or upgrade storage hardware to improve write performance.
Event ID: 4000: Alarm logging error — alarm events cannot be written to the alarm archive.
Check the alarm logging configuration, verify SQL Server connectivity, and ensure sufficient disk space is available for the alarm database.
Event ID: 5000: Script runtime error — a VBScript or C-Script action has encountered an unhandled exception during execution.
Review the script code for syntax or logic errors, check the WinCC diagnostics log for the specific script name and line number, and correct the script accordingly.

Frequently Asked Questions

What is the power tag limit for the 6AV6371-1HQ10-0AX0 WinCC Runtime license?

The 6AV6371-1HQ10-0AX0 corresponds to a specific WinCC Runtime power tag count tier. The exact tag count should be verified against the Siemens order documentation, as WinCC Runtime licenses are available in increments such as 128, 512, 2048, 8192, and 65536 power tags.

Is this WinCC license compatible with TIA Portal?

SIMATIC WinCC V7 is a standalone SCADA platform and is separate from WinCC in TIA Portal (WinCC Basic/Comfort/Advanced/Professional). Integration with TIA Portal projects requires the appropriate TIA Portal WinCC license variant.

What database system does SIMATIC WinCC use for archiving?

SIMATIC WinCC uses Microsoft SQL Server as its backend database for process value archiving and alarm logging. SQL Server is typically installed automatically as part of the WinCC installation process.

Can WinCC 6AV6371-1HQ10-0AX0 be used in a redundant server configuration?

Yes, WinCC V7 supports redundant server configurations where a standby server takes over automatically in the event of a primary server failure, provided the appropriate redundancy license is also installed.

What operating systems are supported by SIMATIC WinCC V7?

SIMATIC WinCC V7 supports 64-bit versions of Windows 10 and Windows Server 2016/2019. Older versions may also support Windows 7, but Siemens recommends using currently supported operating systems for security and compatibility reasons.

Troubleshooting

WinCC Runtime fails to start and displays a licensing error

Open the SIMATIC Automation License Manager and check whether a valid WinCC Runtime license is present and not expired or transferred to another system.

Install or transfer the correct WinCC Runtime license to the target PC using the Automation License Manager. Ensure the license tier matches or exceeds the number of configured power tags in the project.

No communication between WinCC and the connected PLC

Check the WinCC channel diagnostics in the Tag Management editor. Verify the network connection, PLC address settings, and that the correct channel driver is installed and configured.

Correct the channel configuration (IP address, rack/slot, or MPI address), restart the channel driver, and confirm the PLC is reachable via a ping or STEP 7/TIA Portal online connection test.

Process values are not being archived or trend displays show no data

Check the SQL Server service status in Windows Services. Verify that the WinCC archive tags are correctly configured with valid logging cycles and that the archive database is not full or corrupted.

Restart the SQL Server service if stopped, clear old archive data if disk space is exhausted, and reinitialize the archive database if corruption is detected. Verify tag logging configuration in WinCC Explorer.

WinCC project opens but screens display incorrectly or graphics are missing

Check the WinCC project for missing picture files or broken object references. Verify that all required WinCC options and add-ons are installed on the runtime PC.

Reinstall missing WinCC options, restore missing picture files from a project backup, and recompile the project in the WinCC configuration editor before restarting runtime.

Alarm messages are not appearing in the alarm control at runtime

Verify that the WinCC Alarm Logging editor has active alarm blocks configured and that the runtime alarm control is connected to the correct alarm log. Check that the SQL Server alarm database is accessible.

Reconfigure the alarm control object to reference the correct alarm log, ensure the Alarm Logging runtime component is active, and verify SQL Server connectivity and database integrity.
