Siemens 6AV6372-2DF07-1FH4 SIMATIC WinCC
The Siemens 6AV6372-2DF07-1FH4 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 and operator control in industrial automation environments. This specific part number corresponds to a WinCC runtime package with a defined number of power tags, enabling real-time process data visualization and control on standard PC-based hardware.
The WinCC runtime software provides a comprehensive set of features including tag-based process data management, alarm and event logging, trend displays, and historical data archiving. It supports a wide range of communication interfaces and drivers for connecting to Siemens SIMATIC S7 PLCs via PROFIBUS, PROFINET, and MPI, as well as OPC DA/UA connectivity for third-party system integration. The software includes a scripting environment (VBScript and C-Script) for custom automation logic, and supports redundant server configurations for high-availability applications. The platform runs on Windows operating systems and integrates with the broader SIMATIC software ecosystem including STEP 7 and TIA Portal.
WinCC runtime software is widely deployed in process industries such as chemical, pharmaceutical, oil and gas, water treatment, and power generation, where centralized process visualization and data logging are required. It is also used in discrete manufacturing environments for machine monitoring, production reporting, and quality data collection. The scalable tag-count licensing model makes it suitable for both small standalone workstation installations and large distributed multi-server SCADA architectures.

Common Error Codes & System Events
- Event ID: 1000000
- WinCC runtime startup error — the runtime system failed to initialize correctly.
Check Windows Event Viewer for detailed error messages. Verify that all required WinCC services are running and that the license is correctly installed. - Event ID: 1001
- Tag communication error — one or more process tags cannot be read from the connected PLC or data source.
Verify the communication channel configuration, check PLC connection status, and confirm network connectivity between the WinCC server and the PLC. - Event ID: 112
- License not found or invalid — WinCC runtime cannot find a valid license for the configured number of power tags.
Check the installed license using the Siemens Automation License Manager (ALM). Ensure the correct license is installed and not expired or transferred. - Event ID: 10241
- Archive database error — the WinCC process value or alarm archive database is unavailable or corrupted.
Check the SQL Server service status. Run the WinCC database consistency check tool and restore from backup if necessary. - Event ID: 2503
- OPC server connection failure — WinCC cannot establish a connection to the configured OPC DA or OPC UA server.
Verify OPC server is running, check DCOM settings for OPC DA connections, and confirm OPC UA endpoint URL and certificate trust settings. - Event ID: 1726
- Redundancy switchover event — the WinCC system has switched from the primary server to the standby server.
Investigate the cause of the primary server failure. Check network connectivity, hardware status, and WinCC service logs on the primary server before attempting switchback. - Event ID: 10001
- Channel driver error — a WinCC communication channel driver has reported a fault or disconnected.
Restart the affected channel driver in WinCC Channel Diagnosis. Check hardware connections and driver configuration parameters.
Frequently Asked Questions
What is the power tag count for the 6AV6372-2DF07-1FH4 license?
The exact power tag count for this specific part number should be confirmed against the Siemens WinCC ordering data, as the 6AV6372 series covers multiple tag-count tiers. Typically, WinCC runtime licenses in this series range from 128 to 65536 power tags.
Is WinCC 6AV6372-2DF07-1FH4 compatible with TIA Portal?
WinCC runtime licenses in the 6AV6372 series are associated with the classic WinCC platform. Integration with TIA Portal is possible via the WinCC TIA Portal option package, but native TIA Portal HMI projects use WinCC Runtime Professional with different part numbers.
What communication protocols does WinCC support for PLC connectivity?
WinCC supports PROFIBUS DP, PROFINET, MPI, and Industrial Ethernet for Siemens S7 PLC connectivity, as well as OPC DA and OPC UA for third-party system integration. Additional protocol drivers are available as optional channel packages.
Can this WinCC license be transferred to a different PC?
Yes, WinCC licenses managed through the Siemens Automation License Manager (ALM) can be transferred between PCs using a USB dongle or via the ALM software, provided the license terms permit transfer.
What database system does WinCC use for archiving?
WinCC uses Microsoft SQL Server as its backend database for process value archiving, alarm logging, and user administration. The appropriate SQL Server version must be installed and compatible with the WinCC version in use.
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. Verify the license matches the configured number of power tags.
Install or transfer the correct WinCC runtime license using ALM. If using a USB dongle, ensure it is properly connected. Contact Siemens licensing support if the license appears valid but is still rejected.
Process tags show invalid or no values in WinCC runtime
Check the WinCC Channel Diagnosis tool to verify the communication channel status. Confirm the PLC is online and reachable via the configured network interface. Check tag address configuration for errors.
Correct any misconfigured tag addresses or channel parameters. Restore network connectivity between the WinCC PC and the PLC. Restart the affected communication channel driver if necessary.
WinCC archive database becomes unavailable or reports SQL errors
Check the status of the Microsoft SQL Server service in Windows Services. Review the WinCC diagnostic log and Windows Event Viewer for SQL-related error messages.
Restart the SQL Server service if it has stopped. Run the WinCC database repair utility. If the database is corrupted, restore from the most recent backup and reconfigure archiving settings.
WinCC runtime performance degrades over time with slow screen updates
Monitor CPU and RAM usage on the WinCC server PC. Check the number of active tags, archive cycle times, and the number of connected clients. Excessive logging or too many simultaneous client connections can cause performance issues.
Optimize archive cycle times and reduce unnecessary tag logging. Upgrade server hardware RAM or CPU if resources are consistently at capacity. Distribute client load across multiple WinCC servers if the architecture supports it.
OPC DA or OPC UA connection to a third-party system fails
Verify the OPC server is running on the target system. For OPC DA, check DCOM security settings on both the WinCC PC and the OPC server PC. For OPC UA, verify endpoint URL, port availability, and certificate trust configuration.
Adjust DCOM permissions to allow remote OPC DA access, or configure OPC UA certificates as trusted in the WinCC OPC UA configuration. Ensure firewall rules permit the required ports (e.g., TCP 4840 for OPC UA).
