Description
Additional information

The Siemens 6AV6371-2BD18-0AX0 is a WinCC Runtime software license belonging to Siemens' SIMATIC WinCC product family, a professional SCADA and HMI visualization platform. This part number corresponds to a WinCC Runtime license for 128 power tags, enabling process visualization and operator control on PC-based HMI systems. It is part of the broader SIMATIC WinCC V7 software suite developed by Siemens for industrial process monitoring and control.

WinCC Runtime with this license tier supports up to 128 configurable process tags (power tags), providing connectivity to PLCs and field devices via a wide range of communication drivers including PROFIBUS, PROFINET, OPC DA/UA, and Siemens S7 protocol. The software includes a runtime environment for displaying process screens, alarm management, trend logging, and report generation. It runs on standard Windows-based industrial PCs and panel PCs, and supports redundancy configurations for high-availability applications. The platform integrates with the SIMATIC engineering environment and supports scripting via VBScript and C-Script for advanced customization.

This WinCC Runtime license is widely used in manufacturing plants, water and wastewater treatment facilities, energy management systems, and building automation applications where PC-based SCADA visualization is required. The 128 power tag tier is suited to small to medium-sized installations where a limited number of process variables need to be monitored and controlled from a central operator station. Its compatibility with the broader Siemens TIA Portal and SIMATIC ecosystem makes it a common choice for facilities already operating Siemens S7-300, S7-400, or S7-1500 PLC infrastructure.

Common Error Codes & System Events

Event ID: 1000000: WinCC Runtime startup failure. The runtime environment could not be initialized correctly.
Check Windows Event Viewer for detailed error messages. Verify that all required WinCC components are installed and the license dongle is connected.
Event ID: 1000008: License not found or invalid. WinCC Runtime cannot detect a valid license for the configured tag count.
Ensure the USB license dongle (SIMATIC Automation License Manager) is connected and recognized. Verify the license matches the number of configured power tags.
Event ID: 1000020: Communication driver connection failure. WinCC cannot establish a connection to the configured PLC or field device.
Check network/PROFIBUS cabling and PLC address settings. Verify the correct communication driver is installed and the channel parameters match the PLC configuration.
Event ID: 1000040: Tag limit exceeded. The number of configured power tags exceeds the licensed limit of 128.
Reduce the number of active power tags to within the licensed limit, or upgrade the WinCC Runtime license to a higher tag count tier.
Event ID: 1000060: Database connection error. WinCC Runtime cannot connect to the SQL Server database used for logging and archiving.
Verify that Microsoft SQL Server is installed, running, and accessible. Check WinCC database configuration and ensure sufficient disk space is available.
Event ID: 1000080: Redundancy synchronization error. The redundancy partner server cannot be reached or synchronization has failed.
Check network connectivity between the primary and redundancy server. Verify redundancy configuration settings in WinCC and ensure both systems are running compatible WinCC versions.
Event ID: 1000100: Script runtime error. A VBScript or C-Script action has encountered an execution error.
Open the WinCC Script Debugger to identify the faulty script. Review the script logic for syntax errors, null references, or invalid tag accesses.

Frequently Asked Questions

What is the power tag limit for the 6AV6371-2BD18-0AX0 license?

This WinCC Runtime license supports up to 128 power tags, which defines the maximum number of process variables that can be actively connected and monitored at runtime.

Is a hardware dongle required to run this WinCC Runtime license?

WinCC Runtime licenses are typically managed via the Siemens Automation License Manager (ALM). Depending on the license variant, a USB dongle or a software-based license may be required. The ALM software must be installed on the runtime PC.

Which Siemens PLCs are compatible with this WinCC Runtime software?

WinCC Runtime is compatible with SIMATIC S7-300, S7-400, S7-1500, and S7-200 PLCs via the appropriate communication drivers. It also supports third-party devices through OPC DA and OPC UA interfaces.

Can this WinCC Runtime license be used with TIA Portal projects?

WinCC Runtime V7 operates as a standalone SCADA platform and is configured using the WinCC configuration studio, not TIA Portal directly. However, it integrates with the broader SIMATIC ecosystem and can communicate with PLCs programmed in TIA Portal.

What operating systems are supported by this WinCC Runtime version?

SIMATIC WinCC V7 Runtime is supported on 64-bit versions of Windows 10 and Windows Server editions as specified in the Siemens compatibility matrix. It requires Microsoft SQL Server for database functionality.

Troubleshooting

WinCC Runtime fails to start and displays a license error

Check whether the USB license dongle is connected and recognized by Windows Device Manager. Open the Siemens Automation License Manager to verify the license status and tag count.

Reconnect the USB dongle and restart the Automation License Manager service. If the license shows as invalid, transfer a valid 128 power tag Runtime license to the dongle using the ALM tool.

No communication between WinCC Runtime and the connected PLC

Check the WinCC Tag Management to verify the channel and connection settings. Use the WinCC Channel Diagnostics tool to check the connection status and error messages for the configured communication driver.

Verify the PLC IP address or PROFIBUS address matches the WinCC connection configuration. Ensure the correct communication driver is installed and that no firewall or network policy is blocking the connection.

Process tags show invalid or no values at runtime

Check the tag configuration in WinCC for correct address mapping. Verify the PLC data block or memory area referenced by the tags exists and is accessible.

Correct the tag address in WinCC Tag Management to match the actual PLC variable addresses. Ensure the PLC program is running and the relevant data areas are not write-protected.

WinCC alarm system not logging or displaying alarms

Check the WinCC Alarm Logging editor to verify that alarm classes and messages are correctly configured. Confirm that the SQL Server database service is running and the WinCC database is accessible.

Restart the SQL Server service if it has stopped. Verify disk space availability and check WinCC database connection settings. Re-activate the Alarm Logging runtime component if it has been deactivated.

WinCC Runtime performance is slow or screens load with significant delay

Monitor CPU and RAM usage on the runtime PC during operation. Check the number of active tags and screen update cycles configured in WinCC.

Optimize screen update cycles by increasing the update interval for non-critical tags. Ensure the PC meets the minimum hardware requirements for WinCC V7 with 128 tags, and close unnecessary background applications.
