€ 694,67
The Siemens 6AV6371-2BQ18-0AX0 is a WinCC (Windows Control Center) runtime software license belonging to Siemens' SIMATIC HMI software family. It is a PC-based SCADA and HMI visualization software package designed for industrial process monitoring, control, and data acquisition on standard Windows-based hardware platforms. This part number corresponds to a specific WinCC runtime license variant, enabling operator control and monitoring functionality in industrial automation environments.
WinCC offers a comprehensive set of features including tag-based licensing, integrated alarm management, trend displays, and historical data logging. It supports a wide range of communication interfaces and drivers for connecting to SIMATIC S7 PLCs via PROFIBUS, PROFINET, MPI, and Industrial Ethernet, as well as third-party controllers via OPC DA/UA. The software includes a powerful scripting environment (VBScript and C-Script), a graphics designer for building process screens, and supports redundant server configurations for high-availability applications.
SIMATIC WinCC is widely deployed in process industries such as water and wastewater treatment, chemical and pharmaceutical manufacturing, food and beverage production, and energy management. It is equally suited for discrete manufacturing applications including automotive assembly lines and machine tool monitoring. Its scalability from single-station installations to distributed multi-server architectures makes it applicable across a broad range of plant sizes and complexity levels.

Common Error Codes & System Events
- Event ID: 1000000
- WinCC Runtime startup failure. The runtime could not be initialized, often due to a missing or invalid license.
Verify that a valid WinCC runtime license is installed using the Siemens Automation License Manager (ALM). Reinstall the license if necessary. - Event ID: 1001
- Communication error to PLC. The configured channel driver cannot establish a connection to the target controller.
Check network cabling, IP address configuration, and PLC communication settings. Verify the channel driver is correctly configured in WinCC Explorer. - Event ID: 10000
- Tag logging runtime error. The archive database cannot be accessed or written to.
Check available disk space, verify SQL Server service is running, and ensure the archive path is accessible and correctly configured. - Event ID: 1131
- OPC server connection failure. WinCC cannot connect to the configured OPC DA or OPC UA server.
Verify the OPC server is running, check DCOM settings and firewall rules, and confirm the OPC server address and namespace configuration in WinCC. - Event ID: 112
- License not found or license count exceeded. The number of configured tags or clients exceeds the licensed quantity.
Check the installed license using Automation License Manager. Upgrade the license to a higher tag count or reduce the number of configured tags. - Event ID: 1003
- Alarm logging database error. The alarm archive cannot be written, causing alarm loss.
Verify SQL Server is operational, check disk space, and review the alarm logging configuration in WinCC Explorer. Restart the alarm logging runtime if necessary. - Event ID: 2501
- Graphics Runtime error. A process screen cannot be loaded or displayed correctly.
Check for missing or corrupt picture files in the WinCC project directory. Recompile the project and verify all referenced images and controls are present.
Frequently Asked Questions
What is the tag capacity of the 6AV6371-2BQ18-0AX0 WinCC license?
The exact tag count for this specific license variant should be confirmed against the Siemens order documentation, as WinCC licenses are available in multiple tag tiers (e.g., 128, 512, 2048, 65536 tags). The part number suffix indicates the specific licensed configuration.
Is WinCC 6AV6371-2BQ18-0AX0 compatible with SIMATIC S7-1500 PLCs?
Yes, SIMATIC WinCC supports communication with S7-1500 PLCs via PROFINET and Industrial Ethernet using the SIMATIC S7-1200/1500 channel driver. Ensure the correct driver version is installed for the target firmware.
Can this WinCC license be transferred to a different PC?
WinCC licenses are managed via the Siemens Automation License Manager (ALM) and can be transferred to another PC using a USB dongle or software-based license transfer, subject to Siemens licensing terms.
Does WinCC support OPC UA communication?
Yes, SIMATIC WinCC V7 and later versions include an integrated OPC UA server and client, allowing standardized communication with third-party devices and systems that support the OPC UA standard.
What database system does WinCC use for archiving?
WinCC uses Microsoft SQL Server as its underlying database engine for process value archiving, alarm logging, and user administration data storage.
Troubleshooting
WinCC Runtime fails to start and displays a license error
Open the Siemens Automation License Manager (ALM) and check whether a valid WinCC runtime license is present and not expired or corrupted.
Reinstall or transfer the license using ALM. If using a software license, ensure the license file is correctly bound to the current hardware. Contact Siemens licensing support if the license appears valid but the error persists.
No communication between WinCC and the PLC; all tags show error status
Check the WinCC channel driver configuration in WinCC Explorer. Verify the PLC IP address or PROFIBUS address, and test network connectivity using a ping or STEP 7/TIA Portal online connection.
Correct the channel driver settings, ensure the PLC is in RUN mode, and verify that no firewall or network switch is blocking the communication port. Restart the WinCC channel driver after making changes.
Process screens load slowly or graphics are not displayed correctly
Check the PC hardware resources (CPU, RAM, disk I/O) during runtime. Verify that all referenced graphic objects, ActiveX controls, and picture files exist in the project directory.
Optimize process screens by reducing the number of dynamic objects per screen. Ensure the PC meets the minimum hardware requirements for the WinCC version in use. Recompile the project after resolving missing resources.
Alarm archive fills up rapidly or alarm logging stops recording
Check available disk space on the archive drive and review the SQL Server database size limits. Examine the alarm logging configuration for excessively short archiving cycles or misconfigured segmentation settings.
Free up disk space, adjust the archive segmentation and backup settings in WinCC, and configure automatic deletion of old archive segments. Ensure SQL Server maintenance tasks are scheduled and running correctly.
WinCC project cannot be opened after a Windows update or PC migration
Check for version compatibility between the installed WinCC version and the project file version. Review the Windows Event Log for application errors related to WinCC or SQL Server startup failures.
Ensure the WinCC installation is intact by running a repair from the installation media. Restore SQL Server services if they were disabled by the Windows update. Migrate the project using the WinCC Project Duplicator if moving between PCs.
