Description
Additional information

The Siemens 6AV6371-1CD01-1NX0 is a WinCC (Windows Control Center) runtime software license belonging to Siemens' SIMATIC HMI software family. It is a SCADA and HMI visualization software package designed for use on PC-based operator stations, enabling process monitoring, control, and data acquisition in industrial automation environments. This part number corresponds to a WinCC runtime license with a specific tag count configuration, intended for installation on standard industrial PCs or SIMATIC Panel PCs.

WinCC offers a comprehensive set of features including process visualization, alarm management, trend displays, recipe management, and historical data logging. It supports a wide range of communication interfaces and drivers, enabling connectivity to SIMATIC S7 PLCs via MPI, PROFIBUS, and Industrial Ethernet (PROFINET), as well as third-party controllers via OPC DA/UA. The software provides a scalable architecture, allowing expansion from single-station systems to distributed multi-client/server configurations, and includes built-in redundancy support for high-availability applications.

The 6AV6371-1CD01-1NX0 is typically deployed in process industries such as water and wastewater treatment, chemical and pharmaceutical manufacturing, food and beverage production, and energy management. Its PC-based architecture makes it suitable for applications requiring complex data processing, reporting, and integration with enterprise-level IT systems such as MES and ERP platforms. The software is well-suited for facilities requiring centralized supervisory control across multiple production lines or plant sections.

Common Error Codes & System Events

Event ID: 1000000: WinCC Runtime startup error — the runtime could not be initialized correctly, often due to a missing or invalid license.
Verify that the correct WinCC runtime license is installed and activated using the Siemens Automation License Manager (ALM). Reinstall the license if necessary.
Event ID: 1000008: Tag communication error — one or more process tags cannot be read from the connected PLC or data source.
Check the communication channel configuration in WinCC Explorer. Verify PLC connection, network settings, and that the correct driver is loaded and active.
Event ID: 1000022: Database connection failure — WinCC cannot connect to the underlying SQL Server database used for archiving and configuration.
Ensure Microsoft SQL Server is running and accessible. Check SQL Server service status in Windows Services and verify WinCC database instance configuration.
Event ID: 1000040: License tag count exceeded — the number of configured process tags exceeds the licensed tag count for the installed runtime license.
Reduce the number of active process tags to within the licensed limit, or upgrade the WinCC runtime license to a higher tag count tier.
Event ID: 1000051: Redundancy synchronization error — the primary and standby WinCC servers cannot synchronize their data.
Check the network connection between the primary and redundancy server. Verify redundancy configuration settings in WinCC and ensure both systems are running compatible software versions.
Event ID: 1000060: OPC server connection lost — WinCC has lost communication with a configured OPC DA or OPC UA server.
Verify that the OPC server application is running on the target system. Check firewall settings, DCOM configuration (for OPC DA), and network connectivity between the WinCC station and the OPC server.
Event ID: 1000075: Archive backup failure — WinCC was unable to complete a scheduled archive backup of process data or alarm logs.
Check available disk space on the target backup drive. Verify backup path configuration in WinCC and ensure the Windows user account running WinCC has write permissions to the backup directory.

Frequently Asked Questions

What is the tag count for the 6AV6371-1CD01-1NX0 WinCC runtime license?

The 6AV6371-1CD01-1NX0 corresponds to a WinCC runtime license with a defined process tag limit. Refer to the Siemens SIMATIC WinCC ordering data documentation or the Automation License Manager to confirm the exact tag count for this specific license key.

Which operating systems are supported by this WinCC runtime software?

WinCC V7 runtime is supported on 64-bit versions of Windows 10 and Windows Server 2016/2019. It requires Microsoft SQL Server, which is typically included in the WinCC installation package.

Can this WinCC license be used in a client/server configuration?

Yes, WinCC supports single-station and client/server architectures. Additional client licenses are required for each operator station connecting to a WinCC server in a multi-client setup.

Is this WinCC runtime compatible with SIMATIC S7-1500 PLCs?

Yes, WinCC V7 supports communication with SIMATIC S7-1500 PLCs via PROFINET/Industrial Ethernet using the appropriate SIMATIC NET communication drivers.

How is the WinCC license activated and managed?

The license is managed using the Siemens Automation License Manager (ALM) software. The license key is tied to a USB dongle or stored on the hard drive, and ALM is used to transfer, activate, or deactivate licenses as needed.

Troubleshooting

WinCC Runtime fails to start and displays a license error on launch

Open the Siemens Automation License Manager (ALM) and check whether a valid WinCC runtime license is present and not expired or corrupted. Check if the USB license dongle is connected if a hardware-bound license is used.

Reinstall or transfer the correct WinCC runtime license using ALM. If using a USB dongle, ensure it is properly connected and recognized by Windows. Contact Siemens license support if the license appears invalid.

Process tags show invalid or no values in WinCC Runtime

Check the WinCC channel diagnostics in WinCC Explorer under the communication driver. Verify that the PLC is online and reachable via the configured network interface. Use SIMATIC NET diagnostic tools to test the connection.

Correct the channel and connection configuration in WinCC Explorer. Ensure the correct IP address, rack, and slot settings are configured for the target PLC. Restart the WinCC communication driver after making changes.

WinCC alarms are not being logged or displayed in the alarm control

Check the WinCC Alarm Logging editor to verify that alarm classes and message blocks are correctly configured. Confirm that the SQL Server service is running, as alarm archiving depends on the database.

Restart the SQL Server service if it has stopped. Reconfigure alarm logging settings if the configuration is found to be incomplete. Ensure sufficient disk space is available for the alarm archive database.

WinCC client cannot connect to the WinCC server in a multi-station setup

Verify network connectivity between the client and server PCs. Check Windows Firewall settings on the server for blocked WinCC ports. Confirm that the client is configured with the correct server computer name in WinCC Explorer.

Add WinCC and SQL Server exceptions to the Windows Firewall on the server. Ensure both client and server are on the same Windows domain or workgroup with appropriate user permissions. Verify the WinCC server name is correctly entered in the client project configuration.

Historical trend data is missing or gaps appear in the process value archive

Check the WinCC Tag Logging editor to confirm that the relevant tags are configured for archiving with the correct cycle time. Review disk space availability and SQL Server status, as a full disk or stopped database service will interrupt archiving.

Free up disk space on the archive drive and restart the SQL Server service if necessary. Verify that archive tags are correctly assigned and that the archive cycle is active. Consider configuring automatic archive backup and swapping to prevent disk overflow.
