Description
Additional information

The Siemens 6AV6371-2BP17-5AJ0 is a WinCC (Windows Control Center) SCADA/HMI software package belonging to the SIMATIC HMI product family from Siemens. This part number corresponds to a WinCC Runtime or configuration software license, designed to provide supervisory control and data acquisition capabilities on PC-based HMI systems. It serves as the central software platform for visualizing and operating industrial processes on standard PC hardware running Windows operating systems.

WinCC 6AV6371-2BP17-5AJ0 offers a comprehensive set of features including tag-based licensing for scalable process visualization, integrated alarm and event management, historical data logging, and trend displays. The software supports a wide range of communication interfaces including PROFIBUS, PROFINET, MPI, and OPC (OPC DA/UA), enabling connectivity to SIMATIC S7 PLCs and third-party controllers. It provides a powerful scripting environment (VBScript and C-Script), multi-user project capability, and robust security management with user authentication and access control levels.

This WinCC software is widely deployed in process industries such as chemical, pharmaceutical, food and beverage, water treatment, and power generation, as well as in discrete manufacturing environments. It is particularly suited for applications requiring centralized monitoring of large-scale plant operations, where reliable data archiving, reporting, and real-time visualization are critical. The PC-based platform allows integration with enterprise-level IT systems and databases such as Microsoft SQL Server for advanced data management.

Common Error Codes & System Events

Event ID: 1000000: WinCC Runtime startup failure. The runtime could not be initialized, often due to a missing or invalid license.
Verify that a valid WinCC license is installed using the Siemens Automation License Manager (ALM). Ensure the license matches the configured tag count.
Event ID: 1001: Communication error to PLC. The configured channel driver cannot establish a connection to the target controller.
Check network cabling and PROFIBUS/PROFINET configuration. Verify PLC IP address or MPI address settings in the WinCC channel configuration. Confirm the PLC is in RUN mode.
Event ID: 10241: Tag logging error. Process value archiving has failed or the archive database is unavailable.
Check the SQL Server service is running. Verify available disk space and database integrity. Restart the WinCC Tag Logging service if necessary.
Event ID: 10001: License not found or license count exceeded. The number of configured power tags exceeds the licensed tag count.
Check the installed license using Automation License Manager. Upgrade the license to a higher tag count or reduce the number of configured power tags in the project.
Event ID: 112: WinCC project database error. The project could not be opened due to a corrupt or inaccessible database.
Run the WinCC project consistency check. Restore the project from a recent backup. If the database is corrupt, use SQL Server tools to attempt repair.
Event ID: 10050: Alarm logging system error. The alarm server could not write to the alarm archive.
Check disk space and SQL Server availability. Restart the WinCC Alarm Logging runtime component. Verify alarm archive configuration in WinCC Explorer.
Event ID: 10100: OPC server connection failure. WinCC OPC DA or OPC UA client cannot connect to the configured OPC server.
Verify OPC server is running and accessible on the network. Check DCOM settings for OPC DA connections. For OPC UA, verify endpoint URL, certificates, and firewall rules.
Event ID: 10200: User administration error. A user login attempt failed or the user archive is inaccessible.
Verify user credentials and that the WinCC User Administrator is correctly configured. Check that the user archive database is accessible and not locked.

Frequently Asked Questions

What is the tag (power tag) limit for this WinCC license?

The tag count for the 6AV6371-2BP17-5AJ0 license variant determines how many process variables can be connected in runtime. The specific power tag limit is encoded in the license key and must be verified using the Siemens Automation License Manager (ALM). Common WinCC license tiers include 128, 256, 1024, 8192, and 65536 power tags.

Which PLCs and controllers are compatible with WinCC 6AV6371-2BP17-5AJ0?

WinCC natively supports all SIMATIC S7 PLC families (S7-300, S7-400, S7-1200, S7-1500) via PROFIBUS, PROFINET, and MPI. Third-party controllers can be integrated using OPC DA or OPC UA interfaces, as well as a range of additional channel drivers available for Modbus, Allen-Bradley, and other protocols.

Does this WinCC software support multi-user operation?

Yes, WinCC supports a multi-user and multi-client architecture where multiple operator stations can connect to a central WinCC server. The number of client connections depends on the specific license configuration purchased.

What operating system is required to run WinCC 6AV6371-2BP17-5AJ0?

WinCC requires a compatible Microsoft Windows operating system, typically Windows 7 Professional/Ultimate (64-bit) or Windows Server 2008 R2 and later, depending on the WinCC version. Siemens publishes a compatibility list for each WinCC release specifying supported OS versions.

Can WinCC be integrated with enterprise IT systems and databases?

Yes, WinCC uses Microsoft SQL Server as its integrated database engine, enabling straightforward integration with enterprise IT systems. It also supports OPC UA for standardized data exchange and can interface with MES and ERP systems through its open API and scripting capabilities.

Troubleshooting

WinCC Runtime fails to start and displays a license error

Open the Siemens Automation License Manager (ALM) and check whether a valid WinCC license is present and not expired or transferred. Verify the license tag count matches or exceeds the number of power tags configured in the project.

Install or transfer a valid WinCC license using ALM. If the license is on a USB dongle, ensure the dongle is connected. If the tag count is exceeded, either upgrade the license or reduce the number of configured power tags in the WinCC project.

No communication between WinCC and the SIMATIC S7 PLC

Check the channel driver configuration in WinCC Explorer for the correct PLC IP address, rack, and slot settings. Use the Siemens SIMATIC NET diagnostic tools or ping the PLC to verify network connectivity. Confirm the PLC is in RUN mode and not in STOP.

Correct the connection parameters in the WinCC channel configuration. Verify PROFINET or PROFIBUS network cabling and switch/hub settings. Ensure the PC network adapter is correctly configured and that Windows Firewall is not blocking the SIMATIC communication ports.

WinCC project database cannot be opened or is reported as corrupt

Attempt to open the project in WinCC Explorer and note the exact error message. Run the WinCC consistency check tool. Check the Windows Event Viewer for SQL Server errors that may indicate database corruption or service failure.

Restore the project from the most recent backup. If no backup is available, use SQL Server Management Studio to attempt a database repair. Ensure the SQL Server service (WINCC instance) is running and that the Windows user account has sufficient database permissions.

Alarm logging stops recording alarms during runtime

Check available disk space on the drive hosting the WinCC project and SQL Server data files. Open WinCC Alarm Logging and verify the archive configuration and segment settings. Review the WinCC diagnostic log for alarm logging service errors.

Free up disk space or redirect archives to a larger volume. Restart the WinCC Alarm Logging runtime service. If archive segments are full, configure automatic segment management or increase the maximum archive size in the Alarm Logging editor.

Trend displays show no historical data or gaps in process value archives

Verify that the Tag Logging runtime service is active in WinCC Runtime. Check the archive configuration for the affected tags to confirm logging cycles and archive assignments are correct. Inspect SQL Server for errors related to the WinCC archive database.

Restart the Tag Logging runtime service. Correct the archive configuration for affected tags if logging cycles are set to zero or tags are not assigned to an archive. Ensure SQL Server has sufficient resources (disk, memory) to handle the configured logging rate.
