Description
Additional information

The Siemens 6AV6371-1DG07-5AX3 is a software license for SIMATIC WinCC, Siemens' professional SCADA and HMI runtime software platform. This part number corresponds to a WinCC Runtime license with a specific tag count configuration, belonging to the SIMATIC WinCC V7 product family. WinCC serves as a supervisory control and data acquisition system designed for use on standard PC-based hardware running Microsoft Windows operating systems.

WinCC provides a comprehensive set of features including process visualization, alarm management, trending, reporting, and historical data archiving. The software supports a wide range of communication interfaces and drivers, enabling connectivity to SIMATIC S7 PLCs via PROFIBUS and PROFINET, as well as third-party controllers through OPC DA and OPC UA standards. The platform includes a powerful scripting environment based on VBScript and C, allowing for custom logic and dynamic screen behavior. Redundancy configurations and client-server architectures are supported for high-availability installations.

SIMATIC WinCC is widely deployed in process industries such as chemical, pharmaceutical, oil and gas, water treatment, and power generation, as well as in discrete manufacturing environments including automotive assembly and machine building. Its scalability from single-station installations to large distributed multi-client systems makes it suitable for both small machine-level HMI applications and plant-wide SCADA systems. Integration with the broader Siemens TIA Portal ecosystem and MES/ERP systems via standard interfaces is a key advantage in complex automation architectures.

Common Error Codes & System Events

Event ID: 1000000: WinCC Runtime startup failure. The runtime process could not be initialized correctly.
Check Windows Event Viewer for underlying errors. Verify that all required WinCC services are running and that the license dongle or software license is correctly installed.
Event ID: 1001: Communication channel to PLC is interrupted or unavailable.
Verify network connectivity to the PLC, check PROFIBUS/PROFINET configuration, and confirm that the correct communication driver is installed and configured in WinCC.
Event ID: 2501: License not found or license count exceeded. WinCC Runtime cannot start without a valid license.
Insert the correct USB license dongle or verify the software license using Siemens Automation License Manager (ALM). Ensure the tag count of the license matches or exceeds the project requirements.
Event ID: 1130: Alarm logging database error. The alarm archive cannot be written to or read from.
Check available disk space on the archive drive. Verify SQL Server service is running. Reconfigure the alarm logging database path if necessary.
Event ID: 1700: Tag logging error. Process value archiving has failed for one or more tags.
Verify that the SQL Server instance used by WinCC is running. Check disk space and archive configuration. Restart the WinCC Tag Logging service.
Event ID: 3000: OPC server connection failure. WinCC OPC DA or OPC UA server cannot be reached by a connected client.
Check OPC server configuration and DCOM settings for OPC DA connections. For OPC UA, verify endpoint URL, certificates, and firewall rules.
Event ID: 1500: Redundancy switchover event. The active WinCC server has failed and the standby server has taken over.
Investigate the cause of the primary server failure. Check hardware health, network connectivity, and Windows system logs. Restore the primary server and re-synchronize the redundancy pair.

Frequently Asked Questions

What is the tag count supported by the 6AV6371-1DG07-5AX3 license?

The 6AV6371-1DG07-5AX3 corresponds to a WinCC Runtime license with a defined maximum tag count as specified by Siemens for this part number variant. Consult the Siemens Industry Mall or the Automation License Manager to confirm the exact tag count for this specific license key.

Is this WinCC license compatible with TIA Portal projects?

SIMATIC WinCC V7 operates as a standalone SCADA platform and is not the same as WinCC Runtime Advanced or WinCC Comfort used within TIA Portal. Integration with TIA Portal-based projects is possible via OPC UA or dedicated interfaces, but direct TIA Portal project import is not supported in WinCC V7.

What database system does WinCC use for archiving?

SIMATIC WinCC uses Microsoft SQL Server as its underlying database engine for alarm logging, tag logging, and reporting. The appropriate version of SQL Server is typically included or specified with the WinCC installation package.

Can WinCC communicate with third-party PLCs?

Yes, WinCC supports communication with third-party controllers through OPC DA and OPC UA interfaces, as well as through a range of optional communication drivers available from Siemens for various protocols.

Does this license support a client-server architecture?

WinCC V7 supports client-server architectures, but the number of clients and the server configuration depend on the specific license purchased. Multi-client and redundant server setups require appropriate additional licenses.

Troubleshooting

WinCC Runtime fails to start after installation

Check the Siemens Automation License Manager (ALM) to confirm the license is correctly transferred and active. Review the Windows Event Viewer Application and System logs for error messages related to WinCC services or SQL Server.

Ensure the USB license dongle is connected or the software license is properly activated in ALM. Verify that Microsoft SQL Server is installed and running. Reinstall WinCC if service registration errors are present.

Process tags show no values or display connection errors in Runtime

Open the WinCC Channel Diagnostics tool to check the status of communication channels. Verify the PLC IP address or PROFIBUS address configured in the WinCC Tag Management matches the physical device.

Correct any misconfigured connection parameters in WinCC Tag Management. Check network connectivity between the WinCC server and the PLC. Restart the affected communication channel or the WinCC Runtime.

Alarm archive or tag archive stops recording data

Check available disk space on the drive hosting the WinCC project and SQL Server databases. Verify that the SQL Server service (typically WINCC instance) is running in Windows Services.

Free up disk space or redirect archives to a larger volume. Restart the SQL Server WinCC instance and the WinCC Alarm Logging or Tag Logging runtime components. Review archive size limits in the WinCC project configuration.

WinCC client cannot connect to the WinCC server

Verify network connectivity between client and server PCs. Check that the WinCC server name is correctly entered in the client project and that Windows Firewall is not blocking WinCC communication ports.

Add WinCC executable files and required ports to the Windows Firewall exceptions on both client and server. Ensure both machines are in the same Windows domain or workgroup with appropriate user permissions configured in WinCC User Administrator.

WinCC reports a license warning and switches to demo mode

Open the Automation License Manager and check whether the license for the installed WinCC version and tag count is present and valid. Demo mode activates after two hours if no valid license is detected.

Transfer the correct WinCC Runtime license to the local machine or USB dongle using ALM. Ensure the license tag count is sufficient for the number of process tags used in the project. Contact Siemens support if the license appears valid but is not recognized.
