Description
Additional information

The Siemens 6AV6371-1KV08-0BX3 is a WinCC Runtime software license belonging to Siemens' SIMATIC WinCC product family. WinCC (Windows Control Center) is a supervisory control and data acquisition (SCADA) and human-machine interface (HMI) software platform designed for process visualization and operator control on PC-based systems. This specific part number corresponds to a WinCC Runtime package with a defined number of power tags, enabling process data visualization and control on standard industrial or office-grade PC hardware running Microsoft Windows.

The WinCC Runtime software provides a comprehensive set of features including real-time process data display, alarm and event management, historical data logging, and trend visualization. It supports a wide range of communication interfaces and drivers for connecting to SIMATIC S7 PLCs via PROFIBUS, PROFINET, and MPI, as well as third-party controllers through OPC DA/UA interfaces. The runtime environment includes a scripting engine (VBScript and C-Script) for custom automation logic, and supports redundant server configurations for high-availability deployments. Tag-based licensing defines the number of simultaneously active process variables the runtime can handle.

WinCC Runtime is widely deployed in manufacturing, process industries, energy management, water treatment, and building automation applications where centralized process visualization and data acquisition are required. It is particularly suited for applications demanding integration with the broader Siemens TIA Portal ecosystem, SIMATIC S7 controller families, and enterprise-level MES or ERP systems. The software scales from small single-station installations to large distributed multi-server SCADA architectures.

Common Error Codes & System Events

Event ID: 1000000: WinCC Runtime startup failure. The runtime process could not be initialized, often due to licensing or configuration errors.
Verify that the license key is correctly installed using the Siemens License Manager (SIMATIC Automation License Manager). Check the WinCC diagnostics log for detailed error information.
Event ID: 1000008: Communication channel to PLC is unavailable or interrupted. The configured driver cannot establish a connection to the target controller.
Check network cabling and PROFINET/PROFIBUS configuration. Verify PLC IP address or station address settings in the WinCC channel configuration. Confirm the PLC is in RUN mode.
Event ID: 1000040: Tag logging error. WinCC cannot write process values to the archive database, possibly due to disk space or database corruption.
Check available disk space on the archive drive. Verify the SQL Server service is running. Compact or back up the archive database and restart the logging service.
Event ID: 1000070: License tag count exceeded. The number of active power tags in the project exceeds the licensed limit.
Reduce the number of active tags in the project or upgrade the WinCC Runtime license to a higher tag count tier. Use the License Manager to verify the current license capacity.
Event ID: 1000100: Alarm server error. The WinCC alarm server process has encountered a fault and cannot process or display alarms.
Restart the WinCC Runtime and check the alarm configuration for invalid entries. Review the Windows Event Log and WinCC diagnostic files for root cause details.
Event ID: 1000200: OPC server connection failure. WinCC cannot connect to the configured OPC DA or OPC UA server.
Verify OPC server is running and accessible on the network. Check DCOM settings for OPC DA connections or endpoint configuration for OPC UA. Confirm firewall rules permit OPC traffic.
Event ID: 1000300: Script runtime error. A VBScript or C-Script action has generated an unhandled exception during execution.
Open the WinCC Script Editor and review the affected script for syntax or logic errors. Check the WinCC output window for the specific line number and error message, then correct and recompile the script.

Frequently Asked Questions

What is the power tag capacity of the 6AV6371-1KV08-0BX3 WinCC Runtime license?

The 6AV6371-1KV08-0BX3 corresponds to a WinCC Runtime license with 65536 power tags, which defines the maximum number of simultaneously active process variables the runtime can manage. Confirm the exact tag count by checking the Siemens License Manager after installation.

Is WinCC Runtime 6AV6371-1KV08-0BX3 compatible with TIA Portal?

WinCC Runtime V8.x operates as a standalone SCADA platform and is configured using the WinCC Configuration Studio rather than TIA Portal. For TIA Portal-integrated HMI projects, Siemens WinCC Professional (TIA Portal) is the appropriate product.

What communication protocols does this WinCC Runtime support?

WinCC Runtime supports PROFIBUS, PROFINET, MPI, OPC DA, and OPC UA natively. Additional third-party protocols can be added via optional communication drivers available from Siemens.

Can WinCC Runtime be used in a redundant server configuration?

Yes, WinCC Runtime supports server redundancy where a standby server takes over automatically if the primary server fails, ensuring continuous process visualization and data logging.

What operating system is required for WinCC Runtime 6AV6371-1KV08-0BX3?

WinCC Runtime requires a Microsoft Windows operating system, typically Windows 10 (64-bit) or Windows Server editions as specified in the Siemens compatibility list for the installed WinCC version. Always verify the exact OS compatibility matrix for the specific WinCC version being installed.

Troubleshooting

WinCC Runtime fails to start after installation

Check the Siemens Automation License Manager to confirm the license for 6AV6371-1KV08-0BX3 is correctly installed and not expired. Review the WinCC diagnostic log files located in the WinCC installation directory for startup error messages.

Reinstall or transfer the license using the Automation License Manager. Ensure the correct WinCC version is installed for the license. If the database service is not running, start Microsoft SQL Server manually via Windows Services.

Process tags show invalid or no values in the runtime display

Verify the communication channel configuration in WinCC Configuration Studio. Check that the PLC IP address, rack, and slot settings are correct. Use the WinCC Channel Diagnostics tool to test the connection status.

Correct any misconfigured channel parameters and restart the WinCC Runtime. Confirm the PLC is powered and in RUN mode. Check network connectivity between the WinCC PC and the PLC using a ping test.

Historical trend data is not being recorded or is missing

Check that the Microsoft SQL Server service is running. Verify that sufficient disk space is available on the archive drive. Review the WinCC Tag Logging configuration to confirm the correct tags are assigned to archive groups.

Free up disk space or redirect archives to a larger volume. Restart the SQL Server service and the WinCC Runtime. If the database is corrupted, use the WinCC Database Compressor tool to repair or compact the archive.

Alarms are not appearing in the alarm control despite active fault conditions in the PLC

Check the WinCC Alarm Logging configuration to confirm that alarm tags are correctly linked to PLC data blocks or bit addresses. Verify that the alarm server process is running within the WinCC Runtime.

Correct the alarm tag addressing in the Alarm Logging editor and recompile the project. Restart the WinCC Runtime to reinitialize the alarm server. Confirm that the PLC program is setting the expected alarm bits.

WinCC Runtime displays a license exceeded warning and some tags show no value

The number of active power tags in the loaded project exceeds the licensed tag count of the installed 6AV6371-1KV08-0BX3 license. Open the License Manager to confirm the licensed tag limit.

Reduce the number of active tags in the project to within the licensed limit, or upgrade to a higher tag count WinCC Runtime license. Deactivate unused tags or tag groups in the WinCC Tag Management editor.
