€ 3.495,00
The Siemens 6AV6372-2DF77-4XX4 is a software license package belonging to the SIMATIC WinCC SCADA and HMI software family from Siemens. WinCC (Windows Control Center) is a supervisory control and data acquisition platform designed to run on standard PC hardware under Microsoft Windows, providing process visualization, operator control, and monitoring capabilities for industrial automation systems. This particular part number corresponds to a WinCC runtime or configuration software package within the WinCC V7 product generation.
The WinCC software platform offers a comprehensive set of features including a powerful graphics designer for building process screens, an integrated tag management system, alarm and event logging, trend displays, and report generation. It supports a wide range of communication drivers for connecting to Siemens SIMATIC S7 PLCs via PROFIBUS, PROFINET, and MPI, as well as third-party controllers via OPC DA/UA interfaces. The software includes a structured database backend (Microsoft SQL Server) for archiving process values and alarms, and supports redundant server configurations for high-availability installations.
WinCC is widely deployed in process industries such as oil and gas, chemical and pharmaceutical manufacturing, water and wastewater treatment, power generation, and discrete manufacturing. It is suitable for applications requiring centralized monitoring of large-scale plant processes, multi-client visualization architectures, and integration with Siemens TIA Portal or classic STEP 7 engineering environments. The scalable licensing model allows deployment from single-station operator panels up to distributed multi-server SCADA systems.

Common Error Codes & System Events
- Event ID: 1000000
- WinCC Runtime startup failure. The runtime system could not be initialized, often due to missing or corrupt project files.
Check the WinCC project integrity using the project consistency check tool. Verify that all required drivers and components are installed correctly. - Event ID: 1001000
- Communication error to PLC. The configured communication channel to the controller has failed or is unavailable.
Verify network connectivity to the PLC, check the channel configuration in WinCC Tag Management, and confirm the PLC is in RUN mode. - Event ID: 1002000
- Tag archiving error. The process value archive could not write data, typically due to a database connectivity issue.
Check the SQL Server service is running, verify database disk space, and review the WinCC DataMonitor or Archive configuration. - Event ID: 1003000
- License not found or invalid. WinCC Runtime cannot start because a valid license key is not detected.
Use the Siemens Automation License Manager (ALM) to verify the license is installed and not expired. Transfer or repair the license as required. - Event ID: 1004000
- Alarm logging system error. The alarm server failed to initialize or lost connection to the alarm database.
Restart the WinCC alarm logging component, check SQL Server connectivity, and verify the alarm configuration in WinCC Explorer. - Event ID: 1005000
- OPC server connection failure. The WinCC OPC DA or OPC UA server could not establish a connection with a client or external system.
Verify OPC server settings, check Windows DCOM configuration for OPC DA, and confirm firewall rules permit OPC UA port traffic (default 4840). - Event ID: 1006000
- Redundancy switchover event. The active WinCC server has failed and the standby server has taken over operation.
Investigate the cause of the primary server failure, restore the primary server to operational state, and perform a controlled switchback when ready.
Frequently Asked Questions
What is the difference between WinCC Runtime and WinCC Configuration software?
WinCC Configuration software is used by engineers to design and build HMI projects, including graphics, tags, and alarms. WinCC Runtime is the execution environment that runs the finished project for operator use on a production system.
Is the 6AV6372-2DF77-4XX4 compatible with SIMATIC TIA Portal?
WinCC V7 operates as a standalone engineering environment separate from TIA Portal. For TIA Portal-integrated HMI projects, Siemens offers WinCC Comfort/Advanced/Professional. However, WinCC V7 can coexist on the same network as TIA Portal-based controllers.
What communication protocols does WinCC V7 support for connecting to PLCs?
WinCC V7 supports PROFIBUS DP, PROFINET, MPI, Industrial Ethernet, and OPC DA/UA for PLC connectivity. Native Siemens S7 communication drivers are included, and third-party device connectivity is available via OPC interfaces.
Can WinCC V7 be used in a redundant server configuration?
Yes, WinCC V7 supports a redundant server pair configuration where a standby server automatically takes over if the active server fails, ensuring continuous process monitoring with minimal interruption.
What database system does WinCC V7 use for archiving?
WinCC V7 uses Microsoft SQL Server as its backend database for storing process value archives, alarm logs, and audit trail data. The SQL Server instance is typically installed automatically during WinCC setup.
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 to another machine.
Install or transfer a valid WinCC Runtime license using the ALM tool. If using a USB dongle, ensure it is properly connected. Contact Siemens license support if the license is corrupted.
Process tags show no values or display '#COMM' error in Runtime
Check the WinCC channel diagnostics in WinCC Explorer under the communication driver. Verify the PLC IP address or PROFIBUS address is correctly configured and that the network connection is active.
Correct the channel configuration parameters, restore network connectivity to the PLC, and restart the WinCC communication driver. Confirm the PLC is in RUN mode and accessible from the WinCC server.
Alarm logging stops recording new alarms
Check the Windows Event Viewer and WinCC diagnostic log for SQL Server errors. Verify available disk space on the drive hosting the WinCC database and confirm the SQL Server service is running.
Free up disk space, restart the SQL Server service if stopped, and use the WinCC Archive Backup tool to archive and compress old alarm data. Adjust archive size limits in the alarm logging configuration if necessary.
WinCC project opens but graphics screens load slowly or freeze
Monitor CPU and RAM usage on the WinCC server PC during Runtime. Check the number of active tags, update cycles configured, and whether the graphics contain an excessive number of dynamic objects.
Optimize screen designs by reducing the number of dynamic objects per screen, increase tag update cycles where real-time response is not critical, and ensure the server hardware meets the minimum specifications for the configured tag count.
WinCC redundancy standby server does not synchronize with the active server
Check network connectivity between the two redundancy partners on the dedicated synchronization network interface. Review the WinCC redundancy configuration in WinCC Explorer and check the Windows firewall settings on both servers.
Ensure both servers can ping each other on the synchronization network, open required WinCC ports in the Windows firewall, and verify that the redundancy partner computer name is correctly configured in the WinCC redundancy settings.
