€ 1.995,00
The Siemens 6AV6371-1CA08-0AX0 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 use on PC-based operator stations in industrial automation environments. This specific part number corresponds to a WinCC Runtime license with a defined number of power tags, enabling process visualization and monitoring on standard PC hardware running Microsoft Windows.
The WinCC Runtime software provides a comprehensive set of features including process visualization, alarm management, trend display, reporting, and historical data archiving. It supports a wide range of communication drivers and interfaces, including PROFIBUS, PROFINET, MPI, and OPC (OPC DA and OPC UA), enabling connectivity to SIMATIC S7 PLCs and third-party controllers. The runtime environment is scalable in terms of the number of process tags (power tags), allowing the license to be matched to the size and complexity of the installation. Integration with the SIMATIC automation ecosystem, including TIA Portal and STEP 7, is a core capability.
WinCC Runtime is deployed across a broad range of industries including manufacturing, energy, water and wastewater treatment, chemical processing, and building automation. It is used on operator workstations, control room PCs, and server installations where centralized process monitoring and control are required. Its compatibility with standard PC hardware and Windows operating systems makes it suitable for both standalone HMI applications and distributed multi-client/server SCADA architectures.

Common Error Codes & System Events
- Event ID: 1000000
- WinCC Runtime startup error — the runtime could not be started, often due to licensing or configuration issues.
Check that the license key is correctly installed using the Siemens Automation License Manager. Verify the WinCC project configuration for errors before restarting. - Event ID: 1000008
- Communication channel error — a configured communication driver has failed to connect to the target controller.
Verify PLC connection parameters (IP address, rack/slot, MPI address). Check physical network connections and ensure the PLC is in RUN mode. - Event ID: 1000022
- Tag logging error — process value archiving has encountered a fault, possibly due to database issues.
Check the SQL Server or WinCC archive database status. Verify available disk space and database integrity. Restart the archiving service if necessary. - Event ID: 1000040
- Alarm logging overflow — the alarm buffer has reached its maximum capacity.
Increase the alarm buffer size in the WinCC alarm logging configuration, or archive and clear existing alarm records to free buffer space. - Event ID: 1000100
- License not found or invalid — WinCC Runtime cannot find a valid license for the configured number of power tags.
Open the Siemens Automation License Manager and verify that a valid WinCC Runtime license matching the required power tag count is installed and not expired. - Event ID: 1000200
- OPC server connection failure — the WinCC OPC DA or OPC UA server cannot be reached by a connected client.
Check OPC server configuration and DCOM settings (for OPC DA). Ensure firewall rules permit OPC communication on the relevant ports. Verify OPC UA endpoint URLs for OPC UA connections. - Event ID: 1000300
- Project consistency error — the WinCC project has detected inconsistencies, possibly after an incomplete save or version mismatch.
Run the WinCC project consistency check from the WinCC Explorer. Restore from a recent backup if the project cannot be repaired automatically.
Frequently Asked Questions
What is the power tag limit for the 6AV6371-1CA08-0AX0 license?
The 6AV6371-1CA08-0AX0 corresponds to a WinCC Runtime license for 128 power tags. Power tags define the number of process variables that can be actively connected and visualized at runtime.
Is this a perpetual license or a time-limited license?
This is a perpetual (unlimited duration) runtime license. It does not expire, but it is tied to the hardware or software dongle on which it is activated via the Siemens Automation License Manager.
Which version of WinCC does this license apply to?
The 6AV6371-1CA08-0AX0 part number is associated with the SIMATIC WinCC V7 product family. Compatibility with specific sub-versions (e.g., V7.4, V7.5) should be confirmed against the Siemens compatibility matrix.
Can WinCC Runtime communicate with non-Siemens PLCs?
Yes. WinCC Runtime supports OPC DA and OPC UA interfaces, as well as a range of third-party communication drivers, enabling connectivity to PLCs and controllers from other manufacturers.
Does this license support a multi-client/server architecture?
WinCC Runtime licenses are for single-station or server use. A separate WinCC client license is required for each additional operator workstation connecting to a WinCC server in a distributed architecture.
Troubleshooting
WinCC Runtime fails to start and displays a licensing error
Open the Siemens Automation License Manager (ALM) and check whether a valid WinCC Runtime license is present and assigned to the local machine. Check for license transfer issues or expired trial licenses.
Ensure the correct WinCC Runtime license (matching the required power tag count) is installed via ALM. If using a USB dongle, verify it is connected and recognized. Transfer or re-activate the license if it has been moved to another machine.
No communication between WinCC and the SIMATIC S7 PLC
Check the channel diagnostics in WinCC Explorer under the communication driver. Verify the configured PLC IP address, rack, and slot number. Use SIMATIC NET diagnostic tools or ping the PLC to confirm network reachability.
Correct the connection parameters in the WinCC tag management. Ensure the PC's network adapter is configured on the same subnet as the PLC. Verify that no firewall or antivirus software is blocking SIMATIC communication ports.
Historical trend data is not being recorded or is missing
Check the WinCC Tag Logging (process value archiving) configuration to confirm that the relevant tags are assigned to an archive. Verify the SQL Server service is running and that sufficient disk space is available.
Restart the WinCC archiving service and SQL Server if they have stopped. Increase disk space or adjust the archive cycle and storage duration settings. Re-check tag archive assignments in the Tag Logging editor.
Alarms are not appearing in the alarm view at runtime
Verify that alarm logging is active in the WinCC project and that the relevant alarm tags are correctly configured with limit values and message classes. Check that the alarm control is correctly placed and configured on the HMI screen.
Activate alarm logging in the WinCC project settings. Confirm that alarm tag connections reference the correct PLC data addresses. Ensure the WinCC Alarm Control on the screen is set to display the correct message class and time range.
WinCC project opens with consistency errors after a system crash
Run the WinCC project consistency check from WinCC Explorer (right-click the project, select 'Check Consistency'). Identify which editors or components report errors in the output log.
Resolve individual consistency errors as reported by the check tool. If the project is severely corrupted, restore from the most recent backup. Ensure regular project backups are scheduled to minimize data loss in future incidents.
