Description
Additional information

The Siemens 6AV6371-2BQ07-5AJ0 is a WinCC (Windows Control Center) runtime or configuration software package belonging to Siemens' SIMATIC HMI software family. It is a PC-based SCADA and HMI visualization software product designed for industrial process monitoring, control, and data acquisition on standard Windows-based hardware platforms. This part number corresponds to a specific WinCC software variant or upgrade package within the SIMATIC WinCC V7 product line.

WinCC provides a comprehensive set of features including process visualization, alarm management, trend displays, reporting, and historical data archiving. 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 OPC UA and OPC DA for third-party system integration. The software includes a powerful scripting environment (VBScript and C-Script) for custom automation logic, 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 suitable for applications requiring centralized supervisory control over large distributed systems, where operators need real-time visibility into plant status, historical trend analysis, and integrated alarm handling across multiple production lines or facilities.

Common Error Codes & System Events

Event ID: 1000000: WinCC Runtime startup error — the runtime system failed to initialize correctly, often due to a missing or corrupt project file.
Verify the project path and file integrity. Restart the WinCC runtime and check the WinCC diagnostic log for detailed error information.
Event ID: 1001: Communication error to PLC — the connection to the configured SIMATIC S7 controller has been lost or cannot be established.
Check network cabling and PROFINET/MPI configuration. Verify the PLC is powered and reachable. Review the channel diagnostics in WinCC Explorer.
Event ID: 10241: Tag logging error — the archiving system failed to write process values to the database, possibly due to a full disk or database corruption.
Check available disk space on the server. Verify the SQL Server service is running. Compact or back up the archive database and restart the logging service.
Event ID: 10001: License not found — WinCC could not detect a valid license for the installed software package.
Check that the SIMATIC license (via Automation License Manager) is correctly installed and assigned. Transfer or repair the license using the Automation License Manager tool.
Event ID: 20001: Alarm logging system error — the alarm server failed to start or encountered a fault during operation.
Restart the WinCC alarm logging service. Check the WinCC diagnostic files for underlying causes and verify database connectivity.
Event ID: 112: Redundancy switchover event — the active WinCC server has switched over to the standby server due to a detected fault.
Investigate the cause of the primary server failure. Check hardware health, network connectivity, and system event logs on the primary server before attempting failback.
Event ID: 10050: OPC server connection failure — WinCC OPC client cannot connect to the configured OPC server.
Verify OPC server is running and accessible. Check DCOM settings and firewall rules. Confirm OPC server address and namespace configuration in WinCC.

Frequently Asked Questions

What is the WinCC variant or power tag count associated with part number 6AV6371-2BQ07-5AJ0?

The 6AV6371-2BQ07-5AJ0 is a SIMATIC WinCC software package within the V7 product line. The exact power tag count or edition (e.g., 128, 512, 2048 tags) is encoded in the part number suffix and should be confirmed against the Siemens SIMATIC WinCC catalog or the Automation License Manager upon installation.

Which PLCs are compatible with this WinCC software?

WinCC V7 is compatible with the full range of SIMATIC S7 controllers including S7-300, S7-400, S7-1200, and S7-1500, as well as SIMATIC WinAC software PLCs. Third-party PLCs can be integrated via OPC UA or OPC DA interfaces.

Does this WinCC package support multi-user or server-client configurations?

Yes, SIMATIC WinCC V7 supports server-client architectures allowing multiple operator stations to connect to a central WinCC server. Redundant server configurations are also supported for high-availability installations.

What operating systems are supported by SIMATIC WinCC V7?

WinCC V7 supports Windows 7 (64-bit), Windows 10 (64-bit), and Windows Server 2012 R2 / 2016 / 2019, depending on the specific service pack version. Always consult the Siemens compatibility list for the exact OS and SQL Server version requirements.

Is an SQL Server installation required for WinCC V7?

Yes, SIMATIC WinCC V7 requires Microsoft SQL Server for its internal database functions including tag logging, alarm archiving, and reporting. A compatible version of SQL Server (typically SQL Server 2014 or 2017) must be installed prior to WinCC installation.

Troubleshooting

WinCC Runtime fails to start and displays a license error

Open the Siemens Automation License Manager and check whether a valid WinCC license is present and assigned to the local machine or dongle.

Transfer a valid license to the target PC using the Automation License Manager. If the license is on a USB dongle, ensure the dongle is connected. If the license is corrupt, contact Siemens support for license recovery.

No communication between WinCC and SIMATIC S7 PLC

Check the channel diagnostics in WinCC Explorer under the communication driver. Verify the IP address or MPI address configuration matches the PLC settings. Use a PING test or SIMATIC NET diagnostics to confirm network reachability.

Correct the PLC address settings in the WinCC tag management. Ensure the correct communication driver (e.g., SIMATIC S7 Protocol Suite or S7-1500 channel) is installed and configured. Restart the WinCC runtime after making changes.

Historical trend data is missing or not being recorded

Check the WinCC Tag Logging configuration to confirm the relevant tags are enabled for archiving. Verify that the SQL Server service is running and that sufficient disk space is available on the archive drive.

Restart the WinCC Tag Logging service from the WinCC Explorer. If the database is full or corrupt, back up and compact the archive. Increase disk space allocation or configure automatic archive backup and deletion policies.

WinCC project opens but all tag values show '#####' or invalid values

This typically indicates a communication fault or that the WinCC runtime is not connected to the PLC. Check the runtime status bar for communication error indicators and review the channel diagnostics.

Verify PLC connectivity and restart the communication channel in WinCC. If the issue persists, check for mismatched data types between the WinCC tag configuration and the PLC data blocks, and correct the tag definitions accordingly.

WinCC installation fails or rolls back during setup

Check the Windows Event Viewer for installation error codes. Common causes include an incompatible SQL Server version, insufficient user privileges, or a previous incomplete WinCC installation leaving registry entries.

Uninstall any remnants of previous WinCC installations using the Siemens uninstall tool. Ensure the correct SQL Server version is installed and that setup is run with local administrator privileges. Disable antivirus software temporarily during installation.
