Description
Additional information

The Siemens 6AV6371-1DR18-0AX0 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 monitoring on standard PC-based hardware running Microsoft Windows. It is part of the broader SIMATIC WinCC V7 software suite developed by Siemens for industrial process control and supervisory applications.

WinCC Runtime 6AV6371-1DR18-0AX0 provides a scalable runtime environment supporting up to 128 power tags for connecting to process data sources. The software offers a comprehensive set of visualization tools including trend displays, alarm management, reporting, and user administration. It supports communication with SIMATIC S7 PLCs via MPI, PROFIBUS, and Industrial Ethernet (PROFINET), as well as OPC DA/UA interfaces for third-party connectivity. The platform includes an integrated historian for process data archiving and supports redundancy configurations for high-availability installations.

This WinCC Runtime license is widely deployed in manufacturing, process industries, energy management, water treatment, and building automation applications where centralized supervisory control and data acquisition is required. Its PC-based architecture allows integration with enterprise-level IT systems, MES, and ERP platforms. The 128 power tag variant is suited to small-to-medium-scale installations where a defined number of dynamic process variables need to be monitored and controlled from a central operator station.

Common System Event Codes

Event ID: 1000000: WinCC Runtime startup failure — the runtime could not be initialized, often due to a missing or invalid license.
Verify that the license dongle or software license is correctly installed and recognized. Use Siemens Automation License Manager (ALM) to check license status.
Event ID: 1000008: Database connection error — WinCC cannot connect to the integrated SQL Server database.
Check that the Microsoft SQL Server instance (WinCC) is running. Restart the SQL Server service and then restart WinCC Runtime.
Event ID: 1000040: Tag communication error — one or more configured tags cannot be read from the connected PLC or data source.
Verify PLC connection parameters, check network connectivity, and confirm that the channel driver is correctly configured in WinCC Explorer.
Event ID: 1000112: Archive overflow warning — the process data archive has reached its configured size limit.
Increase the archive size limit in WinCC configuration, or set up automatic archiving/backup to offload historical data regularly.
Event ID: 1000200: User administration error — login failure or unauthorized access attempt detected.
Check user account configuration in WinCC User Administrator. Reset passwords or reconfigure user roles as required.
Event ID: 1000300: Redundancy switchover event — the active WinCC server has failed and the standby server has taken over.
Investigate the cause of the primary server failure. Restore the primary server and verify redundancy synchronization status before switching back.
Event ID: 1000500: OPC communication fault — the OPC server connection has been lost or is not responding.
Check OPC server status and network connectivity. Restart the OPC server service and verify OPC channel configuration in WinCC Explorer.

Frequently Asked Questions

How many process tags does the 6AV6371-1DR18-0AX0 license support?

This WinCC Runtime license supports up to 128 power tags, which represent the dynamic process variables that can be connected to live data sources during runtime.

Which PLCs are compatible with this WinCC Runtime license?

WinCC V7 Runtime is compatible with SIMATIC S7-300, S7-400, S7-1200, and S7-1500 PLCs via MPI, PROFIBUS, or Industrial Ethernet (PROFINET). Third-party devices can be connected via OPC DA or OPC UA interfaces.

Is this license tied to a specific PC hardware platform?

WinCC Runtime licenses are managed through the Siemens Automation License Manager (ALM) and are typically bound to the PC on which they are installed or to a USB license dongle, allowing transfer between machines.

Can this WinCC Runtime license be upgraded to support more tags?

Yes, Siemens offers upgrade licenses to increase the power tag count. The WinCC licensing model is scalable, allowing upgrades from 128 tags up to higher tag counts such as 256, 1024, or unlimited tags.

Does this software support OPC UA communication?

Yes, WinCC V7 Runtime supports both OPC DA and OPC UA, enabling integration with third-party SCADA systems, MES platforms, and other automation devices that use these open communication standards.

Troubleshooting

WinCC Runtime fails to start and displays a license error

Open the Siemens Automation License Manager (ALM) and check whether a valid WinCC Runtime 128 power tag license is present and not expired or transferred.

Reinstall the license using ALM, connect the USB license dongle if applicable, or contact Siemens license support to recover a lost license. Ensure the correct license version matches the installed WinCC version.

Tags show no value or display '#' in WinCC Runtime screens

Check the WinCC channel diagnostics in WinCC Explorer under the channel driver for the connected PLC. Verify that the PLC is online and reachable via the configured network interface.

Correct the PLC IP address or MPI/PROFIBUS address in the channel configuration. Verify network connectivity using a ping test. Restart the WinCC channel driver and Runtime if the connection is restored.

WinCC Runtime crashes or freezes intermittently

Review the Windows Event Viewer and the WinCC diagnostic log files located in the WinCC project directory for error entries. Check available RAM and CPU usage during the crash.

Ensure the PC meets the minimum hardware requirements for WinCC V7 Runtime. Apply the latest WinCC service pack and Windows updates. Disable unnecessary background applications and antivirus real-time scanning on WinCC project directories.

Historical trend data is missing or not being archived

Check the WinCC Tag Logging configuration to confirm that the relevant tags are assigned to an archive and that the archive is active. Verify that the SQL Server service is running.

Restart the SQL Server (WinCC) service via Windows Services. Confirm archive configuration in WinCC Explorer and ensure sufficient disk space is available for the archive database.

Alarm messages are not appearing in the alarm control during Runtime

Verify that alarm logging is enabled in WinCC and that the relevant alarm tags are correctly configured with threshold values. Check that the WinCC Alarm Logging server is running.

Review the alarm configuration in WinCC Alarm Logging editor. Ensure the alarm control on the HMI screen is connected to the correct alarm log. Restart WinCC Runtime after making configuration changes.
