Description
Additional information

The Siemens 6AV6371-2BG18-0AJ0 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, forming part of the broader 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, historical data archiving, trend displays, and report generation. The software supports a wide range of communication interfaces and drivers, enabling connectivity to Siemens S7-300, S7-400, S7-1200, and S7-1500 PLCs via PROFIBUS, PROFINET, and MPI, as well as third-party controllers through OPC DA and OPC UA interfaces. The platform includes a powerful scripting environment based on VBScript and ANSI C for custom automation logic, and supports redundant server configurations for high-availability deployments.

SIMATIC WinCC is widely deployed in process industries including chemical, pharmaceutical, oil and gas, water treatment, and power generation, as well as in discrete manufacturing environments such as automotive assembly and food and beverage production. Its scalable architecture allows it to function as a standalone single-station HMI system or as part of a distributed multi-server, multi-client SCADA network. The software's integration with the broader Siemens TIA Portal and SIMATIC IT ecosystem makes it a common choice for large-scale industrial automation projects requiring centralized monitoring and control.

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: 112: Database connection error. WinCC cannot connect to the SQL Server database used for archiving.
Verify that Microsoft SQL Server is running and that the WinCC database instance is accessible. Check SQL Server service status in Windows Services.
Event ID: 10000: Communication channel error. A configured communication driver has lost connection to the target PLC or controller.
Check physical network connections and PLC status. Verify channel and connection parameters in WinCC Explorer. Restart the communication channel if necessary.
Event ID: 1917: License not found or invalid license detected for WinCC Runtime.
Ensure the correct license is installed using the Siemens Automation License Manager (ALM). Verify the license matches the configured tag count and WinCC version.
Event ID: 2501: Tag limit exceeded. The number of active process tags exceeds the licensed tag count.
Reduce the number of active tags to within the licensed limit, or upgrade the WinCC Runtime license to a higher tag count tier.
Event ID: 500: Alarm logging error. WinCC Alarm Logging runtime component encountered a fault and could not record alarm events.
Check available disk space on the archive drive. Verify SQL Server is operational and that the alarm archive database is not corrupted. Restart Alarm Logging runtime if needed.
Event ID: 1003: Script runtime error. A VBScript or C-script configured in WinCC has generated an unhandled exception.
Open the WinCC Script Diagnostics tool to identify the faulty script. Review the script logic for syntax errors or invalid object references and correct accordingly.

Frequently Asked Questions

What tag count does the license 6AV6371-2BG18-0AJ0 support?

The 6AV6371-2BG18-0AJ0 is a WinCC Runtime license within the V7 family. The specific tag count tier should be confirmed against the Siemens order documentation, as the part number suffix encodes the licensed variable count. Consult the Siemens SIMATIC WinCC ordering data sheet for exact tag count confirmation.

Is this WinCC license compatible with TIA Portal?

SIMATIC WinCC V7 operates as a standalone SCADA platform and is not the same as WinCC Advanced or WinCC Unified used within TIA Portal. WinCC V7 can exchange data with TIA Portal-based PLCs via standard communication drivers but is configured through its own WinCC Explorer environment.

What operating systems are supported by SIMATIC WinCC V7?

WinCC V7 supports Microsoft Windows 7 Professional/Ultimate (64-bit), Windows 10 (64-bit), Windows Server 2012 R2, and Windows Server 2016, depending on the specific service pack version installed. Always verify OS compatibility against the specific WinCC V7 service pack release notes.

Can WinCC V7 be used in a redundant server configuration?

Yes, WinCC V7 supports redundant server configurations where two WinCC servers operate in parallel. In the event of a primary server failure, the standby server takes over automatically, ensuring continuous process monitoring and data archiving.

What database engine does WinCC V7 use for archiving?

WinCC V7 uses Microsoft SQL Server as its database engine for process value archiving and alarm logging. A compatible version of SQL Server is typically installed automatically during WinCC installation.

Troubleshooting

WinCC Runtime fails to start after installation

Check the Windows Event Viewer Application and System logs for error entries related to WinCC or SQL Server. Verify that the Siemens Automation License Manager shows a valid license for the installed WinCC version and tag count.

Ensure Microsoft SQL Server is running and the WinCC database has been created successfully. Reinstall the WinCC Runtime if database initialization failed during setup. Confirm the license dongle is connected or the software license is correctly transferred.

No communication between WinCC and PLC

Open WinCC Explorer and check the channel diagnostics for the configured communication driver. Verify network connectivity by pinging the PLC IP address from the WinCC server. Check that the PLC program is running and the configured connection parameters match the PLC settings.

Correct any mismatched IP addresses, rack/slot numbers, or connection names in the WinCC channel configuration. Restart the communication channel within WinCC Explorer. Check firewall settings on the WinCC PC that may be blocking PROFINET or S7 communication ports.

Process values not being archived or trend displays show no data

Verify that the WinCC Tag Logging runtime is active in the WinCC Runtime Explorer. Check available disk space on the drive hosting the SQL Server archive database. Review the archive configuration to confirm tags are assigned to the correct archive.

Free up disk space if the archive drive is full. Restart the Tag Logging runtime component. If the archive database is corrupted, use the WinCC database tools to repair or recreate the archive, then restart the runtime.

Alarm messages not appearing in the alarm window despite process faults

Check that the WinCC Alarm Logging runtime is active. Verify that alarm tags are correctly configured with appropriate limit values and that the alarm window control on the HMI screen is connected to the correct alarm class.

Correct the alarm tag configuration in WinCC Alarm Logging editor. Ensure the alarm window object properties reference the correct server and alarm class. Restart Alarm Logging runtime if the component has stopped unexpectedly.

WinCC reports license error after Windows update or hardware change

Open the Siemens Automation License Manager and check the status of the WinCC Runtime license. Hardware changes such as replacing a network card or hard drive can invalidate a software-bound license.

Use the Automation License Manager to transfer the license back to the PC or reactivate it. If the license was bound to a USB dongle, ensure the dongle is connected. Contact Siemens technical support if the license cannot be recovered after a hardware change.
