Description
Additional information

The Siemens 6AV6371-2BQ18-0AJ0 is a software license package belonging to the SIMATIC WinCC (Windows Control Center) family, Siemens' professional SCADA and HMI runtime and configuration software platform. This part number corresponds to a WinCC Runtime or configuration software package designed for use on standard PC-based hardware running Microsoft Windows operating systems. WinCC is part of the broader Siemens TIA Portal and classic SIMATIC automation ecosystem, providing supervisory control, data acquisition, and visualization capabilities for industrial processes.

The 6AV6371-2BQ18-0AJ0 package provides process visualization, alarm management, trending, and reporting functions for industrial control systems. It supports communication with SIMATIC S7 PLCs via MPI, PROFIBUS, and Industrial Ethernet (PROFINET), as well as OPC DA/UA interfaces for third-party system integration. The software includes tag-based licensing, configurable screen editors, historical data archiving, and multi-client/server architecture support for distributed SCADA deployments. Security features include user authentication, role-based access control, and audit trail logging in compliance with industrial cybersecurity standards.

WinCC software packages such as the 6AV6371-2BQ18-0AJ0 are widely deployed in process industries including chemical, pharmaceutical, water and wastewater treatment, oil and gas, and power generation. They are also used in discrete manufacturing environments for machine monitoring, production line supervision, and quality data collection. The scalable architecture allows deployment from single-station HMI setups to large distributed multi-server SCADA systems covering entire plant operations.

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 invalid license.
Verify that a valid WinCC license is installed using the Siemens Automation License Manager (ALM). Reinstall the license if necessary.
Event ID: 1000001: Database connection error — WinCC cannot connect to the SQL Server database used for archiving and configuration storage.
Check that Microsoft SQL Server is running and accessible. Verify SQL Server instance name and credentials in the WinCC project settings.
Event ID: 1000002: Communication channel fault — the configured communication driver cannot establish a connection to the target PLC or controller.
Verify network connectivity, PLC address settings, and communication driver configuration. Check that the correct channel driver is installed and active.
Event ID: 1000003: Tag logging error — the archive system is unable to log process values, possibly due to disk space shortage or database corruption.
Check available disk space on the archive drive. Compact or back up the WinCC archive database and restart the logging service.
Event ID: 1000004: Alarm logging failure — alarm events are not being recorded, which may indicate a fault in the alarm server or database.
Restart the WinCC Alarm Logging service. Check the SQL Server database for errors and verify alarm logging configuration in the WinCC project.
Event ID: 1000005: License count exceeded — the number of configured or active PowerTags exceeds the licensed tag count for this WinCC installation.
Reduce the number of active tags to within the licensed limit, or upgrade the WinCC license to a higher PowerTag count using the Automation License Manager.
Event ID: 1000006: User Administrator fault — the user management system has encountered an error, preventing user login or access control enforcement.
Check the WinCC User Administrator configuration. Reset user database if corrupted and reconfigure user roles and permissions.
Event ID: 1000007: Graphics runtime error — a WinCC screen or picture object has failed to render, often due to a missing or incompatible ActiveX control or script error.
Check the WinCC output window for script error details. Reinstall any missing ActiveX components and verify VBScript or C-script code in the affected screen.

Frequently Asked Questions

What is the PowerTag count for the 6AV6371-2BQ18-0AJ0 license?

The exact PowerTag count is encoded in the part number variant. The 6AV6371-2BQ18-0AJ0 corresponds to a specific WinCC Runtime license tier; consult the Siemens WinCC ordering data documentation or the Automation License Manager to confirm the tag count for this specific license key.

Is the 6AV6371-2BQ18-0AJ0 compatible with TIA Portal?

WinCC V7.x licenses in this series are primarily designed for the classic SIMATIC WinCC environment. WinCC Runtime Professional within TIA Portal uses a separate licensing structure; verify compatibility with your TIA Portal version before deployment.

What communication protocols does WinCC support with Siemens PLCs?

WinCC supports MPI, PROFIBUS DP, and Industrial Ethernet (PROFINET/TCP/IP) for communication with SIMATIC S7 PLCs. It also supports OPC DA and OPC UA for integration with third-party controllers and systems.

What operating system is required to run this WinCC software?

SIMATIC WinCC V7.x requires a supported version of Microsoft Windows (typically Windows 7, Windows 10, or Windows Server editions depending on the WinCC version). Microsoft SQL Server is also required and is typically included or bundled with the WinCC installation media.

Can WinCC be used in a redundant server configuration?

Yes, WinCC supports redundant server configurations where two WinCC servers operate in parallel, with automatic failover to the standby server in the event of a primary server fault. This requires appropriate licensing for the redundancy option.

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 transferred. Verify the license matches the installed WinCC version and PowerTag count.

Transfer or install the correct WinCC license using the ALM tool. If the license dongle (USB) is used, ensure it is connected. If a software license, verify it has not been moved to another machine.

WinCC cannot communicate with the SIMATIC S7 PLC

Check the communication channel configuration in WinCC Explorer under the channel manager. Verify the PLC IP address or MPI/PROFIBUS address, and confirm network connectivity using a ping test or STEP 7/TIA Portal online diagnostics.

Correct the channel driver settings and PLC address parameters. Ensure the correct communication driver (e.g., SIMATIC S7 Protocol Suite or IE General) is installed and active. Check firewall settings that may block industrial communication ports.

Historical trend data is not being recorded or is missing

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

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

WinCC screens display incorrectly or ActiveX controls are missing

Review the WinCC output window for script errors or missing component warnings. Check whether required ActiveX controls or third-party plugins are registered on the operating system.

Re-register missing ActiveX controls using regsvr32 from the command line. Reinstall any third-party components referenced in the WinCC project. Ensure the WinCC installation is complete and not missing optional components.

Alarms are not appearing in the WinCC Alarm Control at runtime

Verify that the WinCC Alarm Logging server is running in the runtime environment. Check that alarm tags are correctly configured with valid limit values and that the alarm control object on the screen is connected to the correct alarm server.

Restart the Alarm Logging runtime component from WinCC Explorer. Review alarm tag configuration and correct any invalid threshold or trigger settings. Ensure the WinCC Alarm Control on the HMI screen is properly configured to display the correct alarm classes.
