Siemens 6AV6371-1HQ10-0EX0 SIMATIC WinCC

SKU: 6AV6371-1HQ10-0EX0 Category: HMI & Display Brand: Siemens

Description
Additional information

The Siemens 6AV6371-1HQ10-0EX0 is a software license package belonging to the SIMATIC WinCC (Windows Control Center) family, developed by Siemens for SCADA and HMI visualization applications. WinCC is a PC-based supervisory control and data acquisition platform designed to run on standard Windows operating systems, providing runtime visualization and process monitoring capabilities for industrial automation environments. This specific part number corresponds to a WinCC Runtime or upgrade license within the WinCC V7 product generation.

The WinCC platform supports a wide range of communication interfaces including PROFIBUS, PROFINET, MPI, and OPC UA/DA, enabling seamless integration with Siemens SIMATIC S7 PLCs as well as third-party controllers. The software provides features such as process visualization, alarm management, trending and historical data logging, user administration with access control, and scripting via VBScript and C-Script. WinCC supports redundant server configurations for high-availability installations and offers a scalable architecture from single-station systems to distributed multi-server client environments.

WinCC is widely deployed in process industries including chemical, pharmaceutical, water and wastewater treatment, oil and gas, and power generation, as well as in discrete manufacturing environments such as automotive assembly and machine building. Its compatibility with the broader Siemens TIA Portal ecosystem and SIMATIC hardware portfolio makes it a natural choice for facilities already operating Siemens automation infrastructure. The platform is also used in building automation and infrastructure projects where centralized monitoring and control of multiple subsystems is required.

Common Error Codes and System Events

Event ID: 1000000: WinCC Runtime startup failure — the runtime process could not be initialized correctly.
Check Windows Event Viewer for underlying application errors. Verify that all required WinCC services are running and that the license is correctly installed using the Automation License Manager.
Event ID: 1001: Communication channel error — the configured communication driver cannot establish a connection to the PLC or remote device.
Verify network connectivity and PLC address settings. Check that the correct communication driver is installed and configured in WinCC Tag Management.
Event ID: 2501: Archive database error — the WinCC process data archive or alarm archive cannot be accessed or written to.
Check available disk space on the archive drive. Verify SQL Server service is running. Use WinCC Database Repair Tool if the archive is corrupted.
Event ID: 112: License not found — no valid WinCC Runtime license was detected at startup.
Open Siemens Automation License Manager, verify the correct license is present and not expired. Transfer or repair the license as required.
Event ID: 10241: Tag communication error — one or more process tags report a quality code of BAD, indicating loss of communication with the data source.
Check PLC connection status in WinCC Channel Diagnostics. Verify tag address configuration and confirm the PLC program is running.
Event ID: 2000: WinCC project open error — the project could not be opened, possibly due to a corrupted project file or version mismatch.
Restore the project from a recent backup. If a version mismatch is detected, use the WinCC Project Migrator tool to upgrade the project to the installed WinCC version.
Event ID: 4096: Redundancy switchover event — the WinCC redundancy system has detected a failure on the primary server and switched to the standby server.
Investigate the cause of the primary server failure. Check network connections, hardware health, and WinCC service status on the primary server before performing a failback.

Frequently Asked Questions

What is the WinCC Runtime point count for this license?

The exact power tag or point count for part number 6AV6371-1HQ10-0EX0 is defined by the specific license tier encoded in the order number. This part number corresponds to a WinCC Runtime license within the V7 generation; the precise variable count should be confirmed against the Siemens product catalog or the Automation License Manager after installation.

Is WinCC 6AV6371-1HQ10-0EX0 compatible with TIA Portal?

WinCC V7 operates as a standalone SCADA platform and is not the same as WinCC Advanced or WinCC Professional integrated within TIA Portal. It can communicate with TIA Portal-programmed PLCs (S7-1200, S7-1500) via OPC or dedicated channel drivers, but the engineering environment is separate from TIA Portal.

What database engine does WinCC V7 use for archiving?

WinCC V7 uses Microsoft SQL Server as its underlying database engine for process value archiving, alarm logging, and user data storage. The appropriate SQL Server version is typically installed automatically during WinCC setup.

Can WinCC V7 communicate with third-party PLCs?

Yes, WinCC V7 supports OPC DA and OPC UA communication standards, allowing connectivity to third-party PLCs and automation systems that provide an OPC server interface. Additional manufacturer-specific channel drivers may also be available.

What Windows operating systems are supported by WinCC V7?

WinCC V7.x supports Windows 10 (64-bit) and Windows Server 2016/2019 depending on the specific service pack version. It is recommended to consult the Siemens WinCC Readme or compatibility matrix for the exact service pack and OS build requirements.

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 license is present and assigned to the local machine. Verify the license has not expired or been transferred to another host.

If the license is missing, transfer it from the original USB dongle or license medium using ALM. If the license is present but not recognized, perform a license repair within ALM or contact Siemens support for license recovery.

Process tags show BAD quality or no values in WinCC Runtime

Open WinCC Channel Diagnostics to check the status of the communication channel. Verify that the PLC is reachable via ping and that the configured PLC address and rack/slot settings in WinCC are correct.

Correct any misconfigured tag addresses or channel parameters in WinCC Tag Management. Ensure the PLC is in RUN mode and that no firewall rules are blocking the communication port used by the channel driver.

WinCC project cannot be opened after a Windows update or software reinstallation

Check the WinCC version installed against the version used to create the project. A version mismatch or missing SQL Server instance can prevent the project from loading. Review the WinCC error log in the project directory.

Use the WinCC Project Migrator to upgrade the project file to the current installed version. If SQL Server is missing or corrupted, repair or reinstall the SQL Server instance included with WinCC setup.

Alarm archive or process value archive stops recording data

Check available disk space on the drive hosting the WinCC archive. Verify that the SQL Server service (MSSQL$WINCC) is running in Windows Services. Review the WinCC SysDiag tool for archive-related error messages.

Free up disk space or expand the archive storage allocation in WinCC Archive Manager settings. Restart the SQL Server service if it has stopped. If the archive database is corrupted, use the WinCC Database Repair Tool to attempt recovery.

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

Verify network connectivity between client and server. Check that the WinCC project is activated on the server and that the client is correctly configured with the server computer name in the WinCC project properties.

Ensure that Windows Firewall on the server allows WinCC communication ports. Confirm that the client machine has the WinCC Client software installed and that the server project includes the client in its computer list. Restart WinCC services on both machines if necessary.
