Description
Additional information

The Siemens 6AV6371-1KV18-0BX3 is a WinCC Runtime software license belonging to Siemens' SIMATIC WinCC product family. WinCC (Windows Control Center) is a supervisory control and data acquisition (SCADA) and human-machine interface (HMI) software platform designed for use on PC-based operator stations in industrial automation environments. This specific part number corresponds to a WinCC Runtime license with a defined number of power tags, enabling process visualization and operator control on standard PC hardware running Microsoft Windows.

The WinCC Runtime software provides a comprehensive set of features including process visualization, alarm management, trend display, reporting, and historical data archiving. It supports a wide range of communication interfaces and drivers for connecting to Siemens SIMATIC S7 PLCs via PROFIBUS, PROFINET, and MPI, as well as OPC DA/UA connectivity for third-party system integration. The runtime environment supports scripting via VBScript and ANSI C for custom automation logic, and includes a redundancy option for high-availability configurations. The 128 power tag variant (as indicated by the 1KV18 ordering suffix) defines the maximum number of process variables that can be actively connected at runtime.

WinCC Runtime is widely deployed in manufacturing, process industries, energy management, water treatment, and building automation applications where centralized process monitoring and control from a PC workstation is required. It is particularly suited for applications demanding detailed historical logging, complex alarm hierarchies, and integration with enterprise-level systems via standard interfaces such as OPC and SQL databases. The software scales from small single-station installations to large distributed multi-server architectures.

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 detailed error messages. Verify that all required WinCC services are running and that the license dongle or software license is correctly installed.
Event ID: 112: License not found or invalid. WinCC Runtime cannot detect a valid license for the configured number of power tags.
Verify that the USB license dongle is connected or that the software license is correctly activated via the Siemens License Manager (ALM). Ensure the license matches the required power tag count.
Event ID: 10000: Communication error to PLC. The configured channel driver cannot establish a connection to the target controller.
Check network or fieldbus cabling, verify PLC IP address or MPI/PROFIBUS address settings in WinCC Channel Manager, and confirm the PLC is in RUN mode.
Event ID: 10241: Tag read/write error. A process variable could not be read from or written to the connected controller.
Verify the tag address configuration in WinCC Tag Management. Check PLC data block existence and access permissions. Confirm communication channel is active.
Event ID: 1004: Archive database error. WinCC cannot write to or read from the process value or alarm archive database.
Check available disk space on the archive drive. Verify SQL Server service is running. Use WinCC Database Repair Tool if database corruption is suspected.
Event ID: 2: Alarm server error. The WinCC Alarm Server process has encountered a fault and cannot process alarm messages.
Restart the WinCC Alarm Server via the WinCC Control Center. Check system resources (RAM, CPU) and review the WinCC logfile for detailed diagnostics.
Event ID: 1001: Graphics Runtime crash. The WinCC Graphics Runtime (pdlrt.exe) process has terminated unexpectedly.
Review the Windows Event Log and WinCC error log for the root cause. Check for corrupted picture files or script errors in the project. Reinstall WinCC Runtime if the issue persists.

Frequently Asked Questions

How many process tags does the 6AV6371-1KV18-0BX3 license support?

This WinCC Runtime license supports up to 128 power tags (process variables) that can be actively connected and monitored at runtime.

Which PLCs are compatible with this WinCC Runtime software?

WinCC Runtime is compatible with the full range of Siemens SIMATIC controllers including S7-300, S7-400, S7-1200, and S7-1500 series PLCs, connected via MPI, PROFIBUS, or PROFINET. Third-party PLCs can also be integrated via OPC DA or OPC UA interfaces.

Can this WinCC Runtime license be used in a redundant server configuration?

Yes, WinCC supports redundant server configurations, but a separate WinCC Redundancy option package must be licensed in addition to the base Runtime license.

What operating systems are supported by this WinCC Runtime version?

WinCC Runtime is designed for Microsoft Windows operating systems. The specific supported Windows versions depend on the WinCC version; refer to the Siemens compatibility matrix for the exact Windows versions supported by this release.

Is an internet connection required to activate the WinCC Runtime license?

Activation can be performed online via the Siemens Automation License Manager (ALM) or offline using a USB license dongle, making internet connectivity optional depending on the chosen licensing method.

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 with the correct power tag count is present and not expired or transferred.

Reconnect the USB license dongle if used, or re-activate the software license via ALM. If the license has been transferred, retrieve it from the target system using ALM before restarting Runtime.

No communication between WinCC and the SIMATIC PLC

Check the WinCC Channel Manager for the active communication driver. Verify the configured PLC address (IP, MPI address, or PROFIBUS address) matches the actual controller settings. Use Siemens diagnostic tools (e.g., STEP 7 or TIA Portal) to confirm the PLC is reachable on the network.

Correct any address mismatches in the WinCC Tag Management channel configuration. Verify network cabling and switch/router settings. Ensure the correct channel driver version is installed for the target PLC family.

Process values are not updating on WinCC screens

Check the tag status in WinCC Tag Management for error flags. Verify that the power tag count in use does not exceed the licensed limit of 128 tags, which would cause tags to go into error state.

Reduce the number of active tags to within the licensed limit, or upgrade to a higher power tag license. Correct any invalid tag addresses and restart the WinCC Runtime if necessary.

WinCC archive database grows excessively or becomes corrupted

Check available disk space on the archive partition. Review the WinCC archive configuration for archiving cycle times and compression settings. Check SQL Server error logs for database integrity issues.

Increase disk space or adjust archive segmentation and backup settings. Run the WinCC Database Repair Tool to attempt recovery of a corrupted archive. Configure automatic archive backup and deletion of old segments to prevent recurrence.

WinCC Runtime crashes intermittently during operation

Review the Windows Event Log and WinCC log files (located in the WinCC project directory) for error entries at the time of the crash. Check system RAM and CPU utilization during operation.

Ensure the PC meets the minimum hardware requirements for the WinCC version in use. Update WinCC to the latest service pack. Identify and correct any faulty VBScript or C-script functions in the project that may cause memory leaks or unhandled exceptions.
