Siemens 6AV6371-1DV48-0AX0 SIMATIC WinCC

SKU: 6AV6371-1DV48-0AX0 Category: HMI & Display Brand: Siemens

Description
Additional information

The Siemens 6AV6371-1DV48-0AX0 is a WinCC (Windows Control Center) SCADA/HMI software package from Siemens, part of the SIMATIC HMI software family. This part number corresponds to a WinCC runtime or configuration license, designed to run on standard PC-based hardware under Windows operating systems. WinCC serves as a powerful process visualization and supervisory control platform for industrial automation environments.

The software provides a comprehensive set of features including tag-based licensing, process visualization, alarm management, historical data logging, and trend display. 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 OPC DA/UA for third-party system integration. WinCC includes a scripting environment based on VBScript and ANSI C for custom automation logic, and supports redundant server configurations for high-availability installations.

WinCC is widely deployed in industries such as automotive manufacturing, chemical processing, water and wastewater treatment, energy management, and building automation. The software is suited for applications requiring centralized process monitoring, data acquisition, and operator control across large-scale distributed systems. Its scalable architecture allows deployment from single-station installations to multi-client/multi-server configurations with thousands of process tags.

Common Error Codes & System Events

Event ID: 1000000: WinCC Runtime startup failure. The runtime process could not be initialized correctly.
Check Windows Event Viewer for underlying errors. Verify that all required WinCC services are running and that the license dongle or software license is correctly installed.
Event ID: 1001: Communication channel to PLC lost. The configured communication driver cannot establish or maintain a connection to the target controller.
Verify network connectivity and PLC availability. Check channel and connection settings in WinCC Explorer. Confirm correct IP address, MPI address, or PROFIBUS station address is configured.
Event ID: 10241: Tag read/write error. A process tag could not be read from or written to the connected PLC.
Check that the tag address is correctly configured and matches the PLC data block or memory area. Verify the communication connection is active and the PLC program is running.
Event ID: 112: License not found or license count exceeded. WinCC cannot find a valid license for the configured number of tags or clients.
Insert the correct license dongle or verify the software license is activated. Use the Siemens Automation License Manager (ALM) to check license status and available tag count.
Event ID: 10000: Archive server error. The WinCC data logging or process value archive has encountered an error and cannot write historical data.
Check available disk space on the archive drive. Verify that the SQL Server (Microsoft SQL Server used by WinCC) service is running. Review archive configuration in WinCC Explorer.
Event ID: 1004: Redundancy switchover event. The WinCC redundant server has switched from the primary to the standby server.
Investigate the cause of the primary server failure. Check network connectivity, hardware status, and Windows Event Viewer on the primary server. Restore the primary server and perform a manual switchover back if required.
Event ID: 10200: User administration error. An operator attempted an action without sufficient access rights, or the user management database is corrupted.
Verify user roles and access rights in the WinCC User Administrator. If the database is suspected to be corrupted, restore from a backup or reconfigure user accounts.

Frequently Asked Questions

What is the tag capacity of the 6AV6371-1DV48-0AX0 WinCC license?

The exact tag count is encoded in the part number suffix and license type. The 6AV6371-1DV48-0AX0 corresponds to a specific WinCC runtime license tier; consult the Siemens SIMATIC WinCC ordering data sheet or the Automation License Manager to confirm the exact number of process tags included.

What communication protocols does WinCC support for connecting to PLCs?

WinCC supports SIMATIC S7 communication via MPI, PROFIBUS DP, and PROFINET/Industrial Ethernet. It also supports OPC DA and OPC UA for integration with third-party controllers and systems, as well as a wide range of additional channel drivers.

Can WinCC be used in a redundant server configuration?

Yes, WinCC supports server redundancy where a standby server automatically takes over if the primary server fails, ensuring continuous process monitoring and data logging with minimal interruption.

What database engine does WinCC use for historical data archiving?

WinCC uses Microsoft SQL Server as its underlying database engine for process value archiving, alarm logging, and historical data storage. The correct SQL Server version must be installed as a prerequisite.

Is the 6AV6371-1DV48-0AX0 a runtime-only license or does it include the engineering/configuration environment?

WinCC licenses typically include both the configuration (CS) and runtime (RT) environments within the same package, allowing engineering and runtime operation on the same station. Confirm the specific license scope in the Siemens product documentation for this part number.

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 license is detected. Verify the license dongle is connected or the software license is properly activated on the machine.

Insert the correct USB license dongle or transfer the software license to the target PC using ALM. Ensure the license tag count matches or exceeds the number of configured process tags in the project.

No communication between WinCC and the SIMATIC S7 PLC

Check the WinCC channel diagnostics in WinCC Explorer under the communication driver. Ping the PLC IP address from the WinCC PC to verify basic network connectivity. Confirm the connection parameters (IP address, rack, slot) match the PLC configuration.

Correct any mismatched connection parameters in the WinCC channel configuration. Verify that the PC network adapter is on the same subnet as the PLC. Ensure no firewall is blocking the S7 communication port (TCP 102). Restart the WinCC channel if necessary.

Historical data or trend displays show gaps or no data

Check the WinCC archive configuration and verify that the Microsoft SQL Server service is running. Review available disk space on the archive partition. Check the WinCC diagnostic log for archive-related error events.

Free up disk space if the archive drive is full. Restart the SQL Server service if it has stopped. Verify that the archive tags are correctly configured and that the archive server is active in the WinCC project.

WinCC project opens in configuration mode but runtime activation fails

Review the WinCC output window and system event log for specific error messages during activation. Check for conflicting processes or a previous runtime instance that did not shut down cleanly.

Restart the WinCC services via the Windows Services console (search for services starting with 'WinCC'). If a previous runtime session is still active in Task Manager, terminate it. Reopen the project and attempt activation again.

Alarm displays show no alarms even though fault conditions exist in the PLC

Verify that the alarm tags are correctly mapped to the PLC data addresses in the WinCC Alarm Logging editor. Check that the alarm server is running and that the alarm class and group configurations are correct.

Correct any incorrect tag addresses in the Alarm Logging configuration. Ensure the alarm server component is active. Test by forcing a known alarm condition in the PLC and confirming whether the tag value changes are reflected in WinCC tag monitoring.
