Siemens 6AV6371-2BG17-5AJ0 SIMATIC WinCC

SKU: 6AV6371-2BG17-5AJ0 Category: HMI & Display Brand: Siemens

Description
Additional information

The Siemens 6AV6371-2BG17-5AJ0 is a WinCC (Windows Control Center) SCADA/HMI runtime software license belonging to the Siemens SIMATIC WinCC product family. It is designed to provide process visualization, monitoring, and control capabilities on PC-based operator stations within industrial automation environments. This part number corresponds to a specific WinCC runtime or configuration software package with a defined tag count or feature set.

The WinCC software offers a comprehensive set of HMI and SCADA features including process visualization, alarm management, trend displays, reporting, and historical data archiving. It supports communication with Siemens SIMATIC S7 PLCs via MPI, PROFIBUS, and Industrial Ethernet (PROFINET), as well as OPC DA/UA interfaces for third-party system integration. The platform runs on standard Windows-based industrial PCs and supports redundant server configurations for high-availability applications.

SIMATIC WinCC is widely deployed in process industries such as water and wastewater treatment, chemical processing, oil and gas, food and beverage, and power generation. It is also used in discrete manufacturing environments for machine monitoring and production data acquisition. The scalable architecture allows it to be used in single-station installations as well as large distributed multi-client/multi-server SCADA systems.

Frequently Asked Questions

What is the tag count or license scope of the 6AV6371-2BG17-5AJ0?

The exact tag count or runtime scope is defined by the specific license encoded in this part number within the WinCC V7 family. Refer to the Siemens SIMATIC WinCC ordering data or the software license certificate for the precise power tag limit.

Which WinCC version does this part number correspond to?

The 6AV6371-2BG17-5AJ0 belongs to the SIMATIC WinCC V7 product generation. The exact sub-version (e.g., V7.4, V7.5) should be confirmed via the Siemens product catalog or the supplied software media.

Can WinCC communicate with third-party PLCs?

Yes, WinCC supports OPC DA and OPC UA interfaces, allowing communication with third-party controllers and automation systems that support these open standards.

Is this a runtime license or an engineering/configuration license?

WinCC licenses in this series can cover runtime, configuration, or combined functionality. The specific license type for 6AV6371-2BG17-5AJ0 should be verified against the Siemens ordering documentation or the software packaging.

Does WinCC support redundant server configurations?

Yes, SIMATIC WinCC supports server redundancy, enabling a standby server to take over automatically in the event of a primary server failure, ensuring high availability of the visualization system.

Troubleshooting

WinCC runtime fails to start after installation

Check Windows Event Viewer for application errors. Verify that all required Microsoft prerequisites (SQL Server, .NET Framework) are correctly installed and that the license key (USB dongle or software license) is present and recognized.

Install any missing prerequisites as listed in the WinCC installation guide. Ensure the Siemens license dongle is connected or the software license is properly activated using the Siemens Automation License Manager (ALM).

Communication loss between WinCC and S7 PLC

Check the network connection and IP addressing between the PC and the PLC. Verify the channel driver configuration in WinCC Explorer and confirm the PLC is in RUN mode and reachable via ping.

Reconfigure the WinCC channel driver with the correct PLC IP address or MPI/PROFIBUS address. Check firewall settings on the PC that may be blocking S7 communication ports, and ensure the correct communication driver is installed.

Alarm archiving stops recording new alarms

Check available disk space on the archive drive. Review the WinCC alarm logging configuration for archive size limits or circular buffer settings that may have been reached.

Free up disk space or expand the archive storage path. Adjust the archive size limits in the WinCC alarm logging configuration, or enable circular overwrite to prevent archiving from stopping when limits are reached.

WinCC license error displayed at startup

Open the Siemens Automation License Manager (ALM) and check whether a valid license for the installed WinCC version and tag count is present and not expired or transferred.

Transfer or install the correct WinCC license using the ALM tool. If using a USB dongle, ensure it is properly connected. Contact Siemens licensing support if the license appears corrupted or missing.

Trend displays show no historical data

Verify that the WinCC tag logging (process value archiving) is correctly configured and that the archive tags are assigned to the correct process tags. Check that the SQL Server service used by WinCC is running.

Restart the SQL Server service if it has stopped. Reconfigure tag logging in WinCC to ensure archive tags are active and connected to valid process tags. Confirm that the archive storage path is accessible and has sufficient space.
