Siemens 6AV6371-2BN17-5AJ0 SIMATIC WinCC
The Siemens 6AV6371-2BN17-5AJ0 is a WinCC (Windows Control Center) runtime or configuration software license belonging to Siemens' SIMATIC HMI software family. It is a PC-based SCADA and HMI visualization software package designed for industrial process monitoring, control, and data acquisition on Windows-based operator stations. This part number corresponds to a specific WinCC software edition or upgrade package within the SIMATIC WinCC V7 product line.
WinCC provides a comprehensive set of features including tag-based process visualization, alarm management, trend displays, and historical data logging. It supports a wide range of communication interfaces and drivers for connecting to SIMATIC S7 PLCs via PROFIBUS, PROFINET, and MPI, as well as OPC DA/UA for third-party system integration. The software includes a powerful scripting environment (VBScript and C-Script), a graphics designer for building process screens, and a structured archive system for long-term data storage and reporting.
The SIMATIC WinCC platform is widely deployed in industries such as automotive manufacturing, chemical processing, water and wastewater treatment, food and beverage production, and energy management. It is suited for applications requiring centralized supervisory control over large or distributed plant installations, where reliable data acquisition, operator interaction, and audit-trail logging are essential operational requirements.

Common Error Codes & System Events
- Event ID: 1000000
- WinCC runtime startup failure. The runtime system could not be started due to a configuration or licensing error.
Check the WinCC license using the Automation License Manager. Verify that the project configuration is valid and that all required components are installed. - Event ID: 1001
- Communication error to PLC. WinCC cannot establish or maintain a connection to the configured SIMATIC controller.
Check the network connection and PROFIBUS/PROFINET configuration. Verify the PLC IP address or MPI address settings in the WinCC channel configuration. Ensure the PLC is in RUN mode. - Event ID: 10000
- Tag logging error. The archive system failed to write process values to the database.
Check available disk space on the archive drive. Verify that the SQL Server service is running. Review the WinCC diagnostic log for database error details. - Event ID: 2000
- Alarm logging overflow. The alarm buffer has reached its maximum capacity.
Increase the alarm buffer size in the alarm logging configuration. Archive or clear old alarm records. Check for runaway alarm conditions in the process. - Event ID: 112
- License not found or invalid. The required WinCC runtime license could not be validated.
Open the Automation License Manager and verify that a valid license key is present and assigned. Transfer or repair the license if necessary. - Event ID: 50000
- Graphics runtime error. A process screen failed to load or render correctly.
Check the WinCC Graphics Designer project for missing or corrupt picture objects. Recompile the project and restart the runtime. Verify that all referenced dynamic scripts are error-free. - Event ID: 6000
- User administration error. A user login attempt failed or user rights configuration is inconsistent.
Review the WinCC User Administrator settings. Ensure the correct user groups and access rights are configured. Reset the affected user account if necessary.
Frequently Asked Questions
What is the WinCC runtime tag count supported by this license?
The specific tag count (powerTag limit) for part number 6AV6371-2BN17-5AJ0 is defined by the license edition encoded in the order number. WinCC licenses are available in tiers ranging from 128 tags up to unlimited tags; consult the Siemens SIMATIC WinCC ordering data to confirm the exact tag count for this variant.
Which Windows operating systems are compatible with this WinCC software?
SIMATIC WinCC V7 is compatible with Windows 7 Professional/Ultimate (64-bit), Windows Server 2008 R2, Windows 10 (64-bit), and Windows Server 2016/2019, depending on the specific service pack version. Always verify compatibility with the Siemens compatibility tool (SIMATIC Software Compatibility Tool) before installation.
Can WinCC communicate with third-party PLCs or systems?
Yes, WinCC supports OPC DA and OPC UA interfaces, allowing communication with third-party controllers and SCADA systems that support these standards. Additional communication drivers may be required for specific non-Siemens hardware.
Is a SQL Server installation required for WinCC?
Yes, SIMATIC WinCC uses Microsoft SQL Server for its internal database, including alarm logging and tag archiving. A compatible version of SQL Server (typically SQL Server Express or Standard) must be installed, and WinCC setup typically handles this automatically during installation.
Can this WinCC license be transferred to a different PC?
Yes, WinCC software licenses are managed through the Siemens Automation License Manager (ALM). Licenses can be transferred between PCs using a USB dongle or via the ALM software, provided the license type supports transfer.
Troubleshooting
WinCC runtime does not start and displays a license error
Open the Siemens Automation License Manager and check whether a valid WinCC runtime license is present and assigned to the local machine. Check for expired or trial licenses.
Transfer a valid license from a USB dongle or license storage medium using the Automation License Manager. If the license is corrupt, contact Siemens support for license repair or reissue.
No data displayed on process screens; all tags show error status
Check the WinCC channel diagnostics for communication errors. Verify the PLC connection settings including IP address, subnet, and communication driver configuration in the WinCC Tag Management.
Correct the channel configuration parameters, ensure the PLC is reachable on the network, and restart the WinCC channel driver. Check firewall settings that may be blocking PROFINET or S7 communication ports.
WinCC project fails to open and reports a database error
Verify that the Microsoft SQL Server service is running via Windows Services Manager. Check available disk space on the drive where the WinCC project and archives are stored.
Start the SQL Server service if it is stopped. Free up disk space if the drive is full. If the database is corrupt, use the WinCC database repair tool or restore from a recent project backup.
Alarm logging stops recording new alarms
Check the WinCC alarm logging configuration for archive size limits. Review the Windows Event Log and WinCC diagnostic files for database write errors or disk space warnings.
Increase the maximum archive size or enable automatic archiving to a secondary storage location. Clear old alarm archives if disk space is the limiting factor and restart the alarm logging runtime component.
Process screens load slowly or graphics rendering is sluggish
Check CPU and RAM utilization on the WinCC server or client PC. Review the number of dynamic objects and scripts executing on the affected screens. Check for excessive update cycles on tags.
Optimize screen designs by reducing the number of dynamic objects per screen. Increase the tag update cycle times where real-time display is not critical. Upgrade PC hardware RAM or CPU if system resources are consistently at capacity.
