Description
Additional information

The Siemens 6AV6372-2DF07-0DH4 is a WinCC (Windows Control Center) runtime software license belonging to Siemens' SIMATIC HMI software family. WinCC is a supervisory control and data acquisition (SCADA) and human-machine interface (HMI) software platform designed for process visualization, monitoring, and control in industrial automation environments. This specific part number corresponds to a WinCC runtime package with a defined number of PowerTags, enabling process data visualization on standard PC-based hardware running Microsoft Windows.

The WinCC runtime software supports a wide range of communication interfaces and drivers, including PROFIBUS, PROFINET, MPI, and OPC/OPC UA, enabling seamless integration with Siemens SIMATIC S7 PLCs and third-party controllers. It provides features such as alarm management, trend logging, historical data archiving, report generation, and user access control. The software supports redundant server configurations for high-availability applications and includes scripting capabilities via VBScript and C-Script for custom automation logic and screen interactions.

WinCC runtime software is widely deployed in manufacturing, process industries, water and wastewater treatment, energy management, and building automation. Its scalable architecture makes it suitable for both standalone single-station installations and large distributed multi-client/server SCADA systems. The PC-based platform allows integration with enterprise-level IT systems, databases such as Microsoft SQL Server, and standard office applications for reporting and data analysis.

Common Error Codes & System Events

Event ID: 1000000: WinCC runtime startup failure — the runtime could not initialize correctly, often due to missing or corrupt project files.
Verify the WinCC project path is accessible, check Windows Event Viewer for detailed error messages, and ensure all required WinCC components are properly installed.
Event ID: 1001: Communication channel error — the configured communication driver cannot establish a connection to the target PLC or device.
Check physical network connections, verify PLC address and communication parameters in the channel configuration, and confirm the PLC is powered and reachable.
Event ID: 112: Tag logging database error — WinCC cannot write to the SQL Server archive database.
Verify that the Microsoft SQL Server service is running, check available disk space, and review SQL Server error logs for permission or connectivity issues.
Event ID: 10241: License not found — no valid WinCC runtime license was detected on the system.
Insert the Siemens license key (USB dongle or software license), use Siemens Automation License Manager (ALM) to verify license status, and ensure the correct PowerTag count license is installed.
Event ID: 10000: 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 network connectivity between redundant servers, and restore the primary server before performing a manual switchback.
Communication Error: OPC server connection lost — WinCC OPC client cannot reach the configured OPC server.
Verify the OPC server is running, check DCOM security settings on both client and server machines, and confirm firewall rules allow OPC communication.
Alarm: @System: System alarm indicating WinCC internal process or service has stopped unexpectedly.
Restart the affected WinCC service via the SIMATIC Shell or Windows Services manager, review the WinCC diagnostic log files for root cause, and apply any pending software patches.

Frequently Asked Questions

What is the PowerTag count for the 6AV6372-2DF07-0DH4 license?

The 6AV6372-2DF07-0DH4 is a WinCC runtime license; the specific PowerTag count is encoded in the part number variant. Consult the Siemens WinCC ordering data or the Automation License Manager to confirm the exact tag count associated with this license key.

Which Siemens PLCs are compatible with this WinCC runtime software?

WinCC runtime is compatible with the full range of Siemens SIMATIC S7 PLCs including S7-300, S7-400, S7-1200, and S7-1500 via PROFIBUS, PROFINET, or MPI. Third-party PLCs and devices can be integrated using OPC or OPC UA communication channels.

Does this WinCC runtime support redundant server configurations?

Yes, WinCC supports server redundancy where a standby server automatically takes over if the active server fails, ensuring high availability for critical process monitoring applications.

What operating system is required to run WinCC runtime?

WinCC runtime requires a compatible version of Microsoft Windows, typically Windows 10 or Windows Server editions as specified in the Siemens WinCC system requirements for the installed software version.

Can WinCC runtime be used with third-party SCADA or MES systems?

Yes, WinCC supports OPC and OPC UA interfaces, as well as Microsoft SQL Server database connectivity, enabling integration with third-party MES, ERP, and SCADA systems.

Troubleshooting

WinCC runtime fails to start and displays a license error message

Open the Siemens Automation License Manager (ALM) and check whether a valid WinCC runtime license with sufficient PowerTags is present and not expired or transferred.

Insert the correct USB license dongle or transfer the software license to the local machine using ALM. Ensure the license PowerTag count matches or exceeds the number of tags configured in the project.

No communication between WinCC and the connected S7 PLC

Check the channel diagnostics in WinCC Channel Diagnosis tool. Verify the IP address or MPI/PROFIBUS address configured in the WinCC tag management matches the actual PLC settings.

Correct the communication parameters in WinCC tag management, verify physical network connections and switch/hub status, and confirm the PLC is in RUN mode and reachable via a ping test or STEP 7/TIA Portal online connection.

Historical trend data or alarm archives are not being recorded

Check whether the Microsoft SQL Server service is running via Windows Services. Review WinCC diagnostic logs for database write errors or disk space warnings.

Restart the SQL Server service if stopped, free up disk space if the archive drive is full, and verify that the WinCC service account has sufficient permissions to write to the SQL Server database.

WinCC screens load slowly or the runtime becomes unresponsive

Monitor CPU and RAM usage on the PC using Windows Task Manager. Check the number of active tags and logging cycles configured in the project, as excessive polling rates can overload the system.

Optimize tag update cycles by reducing unnecessary fast-cycle tags, increase PC RAM if below recommended specifications, and ensure no other resource-intensive applications are running concurrently on the WinCC server.

User cannot log in to WinCC runtime — access denied error

Check the WinCC User Administrator configuration to verify the user account exists, is enabled, and is assigned to the correct user group with the required authorizations.

Re-create or unlock the user account in WinCC User Administrator, assign the appropriate authorization levels, and ensure the Windows user account running WinCC has the necessary local administrator or service permissions.
