Description
Additional information

The Siemens 6AV6371-2BR18-0AX0 is a WinCC Runtime software license belonging to Siemens' SIMATIC WinCC product family, a professional SCADA and HMI visualization platform for PC-based operator control and monitoring systems. This part number corresponds to a WinCC Runtime license with a 128-PowerTag configuration, enabling process visualization on standard industrial or commercial PC hardware running Windows. It is part of the broader SIMATIC HMI software portfolio from Siemens, designed for use with the TIA Portal or standalone WinCC engineering environments.

The WinCC Runtime software provides a comprehensive set of visualization and control features including process value archiving, alarm logging, trend displays, and user administration with access level management. It supports a wide range of communication interfaces through WinCC channel drivers, including PROFIBUS, PROFINET, MPI, and OPC DA/UA, enabling connectivity to SIMATIC S7 PLCs and third-party controllers. The 128-PowerTag license defines the number of process variables (tags) that can be actively connected and monitored at runtime, making it suitable for small to medium-scale automation projects.

This WinCC Runtime license is commonly deployed in manufacturing plants, process industries, water and wastewater facilities, and building automation systems where PC-based SCADA visualization is required. It is well suited for applications where operators need centralized monitoring of multiple process variables, historical data logging, and alarm management from a single workstation. The software integrates directly with Siemens SIMATIC S7-300, S7-400, S7-1200, and S7-1500 PLC families, making it a natural choice for existing Siemens automation infrastructure.

Common Error Codes & System Events

Event ID: 1000000: WinCC Runtime startup error — the runtime could not initialize correctly, often due to a missing or invalid license.
Verify that the WinCC license (6AV6371-2BR18-0AX0) is correctly installed using the Siemens Automation License Manager (ALM). Ensure the license matches the installed PowerTag count.
Event ID: 1000008: Tag limit exceeded — the number of active process tags has surpassed the licensed PowerTag count.
Reduce the number of active tags to within the 128-PowerTag limit, or upgrade to a higher-tier WinCC Runtime license.
Event ID: 1001000: Communication channel error — WinCC cannot establish a connection to the configured PLC or controller.
Check the physical network connection, verify the channel driver configuration, and confirm the PLC IP address or PROFIBUS address settings in WinCC.
Event ID: 1001001: PLC connection timeout — the configured controller is not responding within the expected time.
Verify PLC is powered and running, check network cabling and switch configuration, and review the WinCC channel driver timeout settings.
Event ID: 1002000: Archive database error — the process value or alarm archive cannot be written to or read from.
Check available disk space on the archive drive, verify SQL Server service is running, and review WinCC archive configuration for correct database path.
Event ID: 1003000: License not found — WinCC Runtime cannot detect a valid license for the installed version.
Open the Siemens Automation License Manager, confirm the license is present and not expired or transferred. Reinstall or transfer the license as needed.
Event ID: 1004000: OPC server connection failure — WinCC OPC DA or OPC UA server cannot be reached by the client application.
Verify OPC server is running, check DCOM settings for OPC DA connections, and confirm OPC UA endpoint URL and certificate configuration for OPC UA connections.
Event ID: 1005000: Alarm logging system error — the WinCC alarm server has encountered an internal fault and alarm records may not be stored correctly.
Restart the WinCC Runtime and alarm logging service. If the issue persists, check the SQL Server instance used by WinCC and repair the alarm archive database.

Frequently Asked Questions

What does the '128 PowerTag' specification mean for this WinCC Runtime license?

PowerTags refer to the number of process variables (tags) that can be actively connected and monitored during runtime. The 6AV6371-2BR18-0AX0 license permits up to 128 simultaneously active process tags.

Which PLCs are compatible with this WinCC Runtime software?

This WinCC Runtime license supports communication with Siemens SIMATIC S7-300, S7-400, S7-1200, and S7-1500 PLCs via PROFIBUS, PROFINET, and MPI. Third-party controllers can also be connected via OPC DA or OPC UA interfaces.

Is this license compatible with the TIA Portal engineering environment?

WinCC Runtime licenses of this type are associated with the classic WinCC (SCADA) platform. For TIA Portal-based projects, WinCC Runtime Advanced or WinCC Professional licenses are typically used. Verify compatibility with your specific WinCC version before installation.

How is this software license managed and transferred?

The license is managed using the Siemens Automation License Manager (ALM). It can be transferred between PCs using a USB dongle or via the ALM software, provided the license is not simultaneously active on multiple machines.

What operating systems are supported by this WinCC Runtime license?

WinCC Runtime is supported on Windows operating systems; the specific supported versions depend on the WinCC software release. Refer to the Siemens WinCC compatibility list for the exact Windows versions supported by your installed WinCC version.

Troubleshooting

WinCC Runtime fails to start and displays a license error

Open the Siemens Automation License Manager (ALM) and check whether the WinCC Runtime license is present, valid, and not expired. Confirm the license PowerTag count matches the installed runtime configuration.

If the license is missing, reinstall it from the original license media or transfer it from another machine using ALM. If the license is present but invalid, contact Siemens support for license recovery.

No communication between WinCC Runtime and the connected PLC

Check the WinCC channel driver configuration for the correct PLC address (IP or PROFIBUS address). Verify network connectivity by pinging the PLC from the WinCC PC. Review the WinCC diagnostic log for channel-specific error messages.

Correct the PLC address in the WinCC tag management, ensure the network cable and switch are functioning, and restart the WinCC channel driver. For PROFIBUS connections, verify the bus termination and cable integrity.

Process values are not being archived and historical trends show no data

Check that the SQL Server instance used by WinCC is running. Verify available disk space on the archive drive. Review the WinCC archive configuration to confirm the correct database path and archive cycle settings.

Start the SQL Server service if it is stopped, free up disk space if necessary, and verify the archive configuration in WinCC. If the archive database is corrupted, use the WinCC database repair tools or restore from a backup.

Tag limit warning appears during runtime operation

The number of active process tags has reached or exceeded the 128-PowerTag limit of the installed license. Review the WinCC tag list to identify all active external tags consuming the license count.

Reduce the number of active external tags to within the 128-tag limit by deactivating unused tags, or upgrade to a higher-capacity WinCC Runtime license to accommodate additional tags.

WinCC Runtime screen displays stale or frozen process values

Check the communication status of the PLC connection in WinCC diagnostics. Verify the PLC is running and not in STOP mode. Check for network interruptions or high CPU load on the WinCC PC that may be causing update delays.

Restart the WinCC channel driver and verify PLC status. Reduce screen update cycles if CPU load is high. If the issue persists, check for network packet loss using network diagnostic tools and resolve any infrastructure issues.
