Description
Additional information

The Siemens 6AV6371-1BV38-0AX0 is a software license package belonging to the SIMATIC WinCC (Windows Control Center) family, Siemens' professional SCADA and HMI runtime 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 a core component of the Siemens TIA Portal and classic SIMATIC automation ecosystem, providing supervisory control, data acquisition, and visualization capabilities for industrial processes.

The 6AV6371-1BV38-0AX0 package provides process visualization, alarm management, trend logging, and reporting functions within the WinCC environment. 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, historical data archiving, and configurable user administration with access level control. Runtime performance supports high-resolution graphics, dynamic process screens, and multi-client/server architectures depending on the license tier.

WinCC is widely deployed in process industries including chemical, pharmaceutical, water and wastewater, oil and gas, and power generation, as well as in discrete manufacturing environments such as automotive assembly and machine building. Its scalability from single-station installations to distributed multi-server architectures makes it suitable for both small standalone HMI applications and large plant-wide SCADA systems. Integration with SIMATIC PCS 7 and the broader Siemens Totally Integrated Automation (TIA) framework further extends its applicability in complex automation projects.

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 the WinCC license is correctly installed using the Siemens Automation License Manager (ALM). Ensure the license matches the configured tag count and runtime version.
Event ID: 1000008: Database connection error — WinCC cannot connect to the underlying SQL Server database used for archiving and configuration storage.
Check that Microsoft SQL Server is running and accessible. Verify SQL Server instance name and service account permissions in the WinCC project settings.
Event ID: 112: Tag communication error — one or more process tags cannot be read from the connected PLC or data source.
Check the communication channel configuration, verify PLC address settings, and confirm network connectivity between the WinCC station and the PLC.
Event ID: 1000040: Archive backup failure — the historical data archiving process could not complete a scheduled backup.
Check available disk space on the archive drive, verify backup path permissions, and review the WinCC archive settings for correct backup destination configuration.
Event ID: 2503: OPC server connection failure — WinCC cannot establish or maintain a connection to a configured OPC DA or OPC UA server.
Verify OPC server is running and accessible. Check DCOM settings for OPC DA connections or endpoint URL and certificate trust for OPC UA connections.
Event ID: 1000020: License tag count exceeded — the number of configured process tags in the project exceeds the licensed tag limit.
Reduce the number of active tags in the project to within the licensed limit, or upgrade the WinCC license to a higher tag count tier using the Automation License Manager.
Event ID: 1000003: Project load error — WinCC was unable to open or load the configured project, possibly due to file corruption or version mismatch.
Verify project file integrity, ensure the WinCC software version matches the project version, and attempt to restore from a recent project backup.

Frequently Asked Questions

What is the tag-based licensing model for WinCC and how does it affect this package?

WinCC licenses are sold based on the number of process tags (variables) that can be active in the runtime. The 6AV6371-1BV38-0AX0 corresponds to a specific tag count tier; the project must not exceed this limit or a license violation event will be triggered. The Siemens Automation License Manager (ALM) is used to manage and verify installed licenses.

Is WinCC 6AV6371-1BV38-0AX0 compatible with the TIA Portal engineering environment?

WinCC in the classic (non-TIA) variant is configured using the standalone WinCC Configuration Studio, while TIA Portal-integrated WinCC is a separate product line. Depending on the specific version of this package, compatibility with TIA Portal should be verified against the Siemens product documentation for this part number.

What communication protocols does WinCC support for connecting to SIMATIC PLCs?

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

Can WinCC be used in a multi-user client/server configuration?

Yes, WinCC supports client/server architectures where a WinCC Server hosts the project and runtime data, and multiple WinCC Clients connect to it for visualization. The number of clients supported depends on the specific license tier purchased.

What database engine does WinCC use for historical data archiving?

WinCC uses Microsoft SQL Server as its underlying database engine for storing configuration data, process value archives, and alarm logs. The appropriate SQL Server version 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 license is present and not expired or transferred. Verify the license matches the installed WinCC version and tag count.

Transfer or install the correct WinCC license using ALM. If the license is on a USB dongle, ensure the dongle is connected. If the license was previously on another machine, perform a license transfer back to the current system.

Process tags show 'Bad Quality' or no values in the WinCC runtime

Check the communication channel status in WinCC Channel Diagnostics. Verify PLC IP address or PROFIBUS address configuration and confirm the PLC is powered and reachable from the WinCC PC via ping or network test.

Correct any misconfigured channel addresses in the WinCC tag management. Restore network connectivity between the WinCC station and the PLC, and restart the affected communication channel driver.

WinCC historical archives are not recording data or archive files grow unexpectedly large

Check the WinCC Archive Manager status and review the archive configuration for logging cycle and compression settings. Verify available disk space on the archive storage drive.

Free up disk space if necessary and adjust archive segmentation and backup settings. Review tag logging cycles to ensure they are appropriate for the process update rate and reduce unnecessary high-frequency logging.

WinCC project fails to load after a software update or Windows update

Check the WinCC diagnostic log files located in the WinCC installation directory for specific error messages. Determine whether the project version is compatible with the currently installed WinCC software version.

If a version mismatch exists, migrate the project using the WinCC project migration tool. If Windows updates caused driver or SQL Server conflicts, roll back the problematic update or reinstall the affected WinCC components.

Alarms are not appearing in the WinCC Alarm Control despite active fault conditions in the PLC

Verify that the alarm tags are correctly configured in WinCC Alarm Logging and that the associated PLC tags have the correct addresses. Check that the WinCC Alarm Logging runtime component is active.

Correct any misconfigured alarm tag addresses and ensure the Alarm Logging component is enabled in the WinCC project. Restart the WinCC runtime and confirm that PLC bit addresses triggering alarms are being read correctly by monitoring tag values in WinCC Tag Management.
