€ 2.495,00
The Siemens 6AV6371-1DQ17-5CX0 is a SIMATIC WinCC runtime software license belonging to Siemens' established SCADA and HMI visualization platform. This part number corresponds to a WinCC runtime package with a 65536 PowerTag (process variable) license, designed for use on standard PC-based hardware running Windows operating systems. It serves as the core visualization and process control software for industrial supervisory control and data acquisition applications.
WinCC 6AV6371-1DQ17-5CX0 provides a comprehensive set of features including tag-based process visualization, alarm management, trend displays, historical data archiving, and report generation. The software supports a wide range of communication interfaces through Siemens channel drivers and OPC connectivity, enabling integration with SIMATIC S7 PLCs, third-party controllers, and field devices. It includes a robust scripting environment (VBScript and C-Script) for custom automation logic, and supports multi-client/server architectures for distributed HMI deployments.
This WinCC runtime license is widely deployed in process industries such as chemical, pharmaceutical, water and wastewater treatment, oil and gas, and power generation, as well as in discrete manufacturing environments. Its scalability from small single-station installations up to large distributed multi-server systems makes it suitable for both standalone machine-level visualization and plant-wide SCADA solutions. The software integrates natively with the Siemens TIA Portal ecosystem and broader SIMATIC automation infrastructure.

Common Error Codes & System Events
- Event ID: 1000000
- WinCC runtime startup failure — the runtime could not be activated, often due to a licensing or configuration error.
Check that the license key is correctly installed using the Siemens Automation License Manager. Verify the project configuration and review the WinCC diagnostics log for details. - Event ID: 1001
- Communication channel error — a configured communication driver has lost connection to the target PLC or device.
Verify network connectivity to the target controller, check channel driver configuration, and confirm the PLC is in RUN mode. Restart the channel driver if necessary. - Event ID: 112
- Tag logging runtime error — the archiving system cannot write process values to the database.
Check available disk space on the archive drive, verify SQL Server service is running, and review the WinCC data manager logs for database errors. - Event ID: 10241
- Alarm logging error — alarm events cannot be stored, typically due to a database or configuration issue.
Ensure the alarm logging database is accessible, check SQL Server status, and verify alarm logging is correctly configured in the WinCC project. - Event ID: 2503
- License not found or insufficient PowerTags — the number of configured tags exceeds the licensed limit.
Verify the installed license using the Automation License Manager. Reduce the number of configured tags or upgrade to a higher PowerTag license tier. - Event ID: 1920
- OPC server connection failure — WinCC cannot establish a connection to an external OPC DA or OPC UA server.
Confirm the OPC server is running and accessible on the network. Check DCOM settings for OPC DA connections, or verify OPC UA endpoint configuration and certificates. - Event ID: 4096
- Graphics runtime error — a WinCC screen or picture object failed to load or render correctly.
Check the project for missing or corrupt picture files. Recompile the project graphics and ensure all referenced objects and scripts are valid.
Frequently Asked Questions
What is the PowerTag count for the 6AV6371-1DQ17-5CX0 license?
This license provides 65536 PowerTags (process variables), making it suitable for large-scale SCADA and HMI installations with a high number of connected data points.
Is this a runtime-only license or does it include the WinCC configuration environment?
The 6AV6371-1DQ17-5CX0 is a runtime license. A separate WinCC engineering or configuration license is required to create and modify WinCC projects.
Which PLCs and controllers are compatible with this WinCC runtime?
WinCC supports SIMATIC S7-300, S7-400, S7-1200, and S7-1500 PLCs natively via SIMATIC channel drivers. Third-party controllers can be integrated via OPC DA/UA or additional communication drivers.
Can this WinCC runtime be used in a client/server architecture?
Yes, WinCC supports multi-client/multi-server architectures. Additional client licenses are required for each client station connecting to a WinCC server.
What database system does WinCC use for archiving?
WinCC uses Microsoft SQL Server for process value and alarm archiving. The appropriate SQL Server version must be installed and running on the WinCC station.
Troubleshooting
WinCC runtime fails to activate or start after project loading
Check the Siemens Automation License Manager to confirm the runtime license is present and valid. Review the WinCC system log (Control Center) for specific error event IDs related to licensing or configuration.
Reinstall or transfer the license using the Automation License Manager. If the license is present but invalid, contact Siemens support for license repair. Ensure the WinCC version matches the project version.
No data displayed on HMI screens — all tags show '#####' or invalid values
Verify the communication channel status in WinCC Channel Diagnostics. Check network connectivity to the target PLC and confirm the PLC is in RUN mode. Review channel driver configuration for correct IP address or MPI/PROFIBUS address.
Correct the communication channel configuration, restore network connectivity, and restart the affected channel driver from the WinCC Control Center. Ensure firewall rules permit communication on the required ports.
WinCC archiving stops recording process values or alarms
Check available disk space on the archive partition. Verify that the Microsoft SQL Server service is running. Review the WinCC data manager and tag logging error logs for database-related events.
Free up disk space or expand the archive storage. Restart the SQL Server service if it has stopped. If the database is corrupt, use the WinCC database tools to repair or reinitialize the archive database.
WinCC project opens in configuration mode but runtime performance is slow or screens load slowly
Check CPU and RAM utilization on the WinCC station. Verify that the number of active tags does not exceed the licensed PowerTag limit. Review script execution times and check for inefficient VBScript or C-Script routines.
Optimize screen designs by reducing the number of dynamic objects per screen. Review and optimize custom scripts. Upgrade hardware if system resources are insufficient, or reduce the scan cycle times for non-critical tags.
OPC DA connection to a third-party system fails
Verify DCOM settings on both the WinCC server and the OPC server machine. Check that the OPC server application is running and that the correct ProgID is configured in the WinCC OPC channel. Review Windows Event Viewer for DCOM-related errors.
Configure DCOM permissions to allow remote activation and launch for the OPC server application. Ensure matching user credentials on both machines. Consider switching to OPC UA if available, as it avoids DCOM configuration complexity.
