Description
Additional information

The Siemens 6AV6371-1HR18-0AX0 is a WinCC (Windows Control Center) runtime software license belonging to Siemens' SIMATIC HMI software family. WinCC is a supervisory control and data acquisition (SCADA) and human-machine interface (HMI) software platform designed for process visualization and operator control on PC-based systems. This particular part number corresponds to a WinCC runtime package with a defined tag/variable count, intended for use on standard industrial or office-grade PC hardware running Microsoft Windows.

The WinCC runtime software provides a comprehensive set of features including process visualization, alarm management, trend display, historical data logging, and reporting functions. It supports a wide range of communication interfaces and drivers, enabling connectivity to SIMATIC S7 PLCs via PROFIBUS, PROFINET, MPI, and Industrial Ethernet, as well as third-party controllers through OPC DA/UA interfaces. The software includes a scripting environment based on VBScript and C for custom automation logic, and supports redundant server configurations for high-availability applications. The 6AV6371-1HR18-0AX0 variant supports up to 128,000 process tags, making it suitable for large-scale visualization projects.

WinCC is widely deployed in process industries such as oil and gas, chemical processing, water and wastewater treatment, power generation, and manufacturing automation. Its scalability from small single-station installations to distributed multi-server architectures makes it applicable across a broad range of plant sizes and complexity levels. The software integrates natively with the SIMATIC automation ecosystem, including S7-300, S7-400, S7-1200, and S7-1500 controller families, and is commonly used as the visualization layer in both standalone and TIA Portal-integrated projects.

Common Error Codes & System Events

Event ID: 1000000: WinCC runtime startup error — the runtime system failed to initialize correctly, often due to a licensing or configuration issue.
Check the WinCC license using the Automation License Manager. Verify that the correct runtime version is installed and that the project configuration is valid.
Event ID: 1000003: Tag communication error — one or more process tags cannot be read from the connected PLC or data source.
Check the communication channel configuration, verify PLC connection parameters (IP address, rack/slot), and confirm the PLC is in RUN mode.
Event ID: 1000010: Archive database error — the WinCC archive database (Microsoft SQL Server) is unavailable or has encountered a fault.
Check that the SQL Server service is running on the WinCC server. Verify disk space availability and database integrity using SQL Server Management Studio.
Event ID: 1000020: License count exceeded — the number of active runtime tags exceeds the licensed tag count for this software package.
Reduce the number of active tags in the project to within the licensed limit, or upgrade the WinCC license to a higher tag count tier.
Event ID: 1000030: 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 (network, hardware, or software fault). Restore the primary server and re-synchronize the redundancy pair.
Event ID: 1000040: OPC server connection lost — the WinCC OPC DA or OPC UA client has lost connection to the configured OPC server.
Verify that the OPC server application is running and accessible on the network. Check firewall settings and DCOM configuration for OPC DA connections.
Event ID: 1000050: Script runtime error — a VBScript or C script within the WinCC project has encountered a runtime exception.
Open the WinCC Script Diagnostics tool to identify the faulty script and line number. Correct the script logic and re-test in the WinCC Graphics Designer.

Frequently Asked Questions

What is the maximum number of process tags supported by the 6AV6371-1HR18-0AX0 license?

The 6AV6371-1HR18-0AX0 WinCC runtime license supports up to 128,000 process tags, making it suitable for large-scale SCADA and HMI visualization projects.

Which SIMATIC PLCs are compatible with this WinCC runtime software?

This WinCC runtime is compatible with the full range of SIMATIC S7 controllers, including S7-300, S7-400, S7-1200, and S7-1500 families, communicating via MPI, PROFIBUS, PROFINET, or Industrial Ethernet.

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

Yes, WinCC supports server redundancy. A separate WinCC redundancy license is required in addition to the runtime license to enable automatic failover between primary and standby servers.

Is this WinCC software compatible with TIA Portal?

WinCC V7 runtime can be integrated with TIA Portal projects, though full TIA Portal-native HMI development uses WinCC Advanced or WinCC Professional. The 6AV6371-1HR18-0AX0 is part of the classic WinCC V7 product line.

What database system does WinCC use for archiving?

WinCC uses Microsoft SQL Server as its underlying database engine for process value archiving, alarm logging, and historical data storage. SQL Server is installed automatically as part of the WinCC installation.

Troubleshooting

WinCC runtime fails to start and displays a licensing error

Open the Siemens Automation License Manager (ALM) and check whether a valid WinCC runtime license of the correct tag count is present and bound to the local machine or USB dongle.

Transfer or activate the correct WinCC runtime license using the Automation License Manager. Ensure the license matches the installed WinCC version and tag count. If using a USB dongle, verify it is properly inserted and recognized by the system.

Process tags show '#COMM' or communication error status in the WinCC runtime

Check the WinCC Channel Diagnostics tool to identify which communication channel or tag group is reporting errors. Verify the PLC IP address, rack, and slot configuration in the WinCC Tag Management.

Correct the communication channel parameters in WinCC Tag Management. Confirm the PLC is powered on and in RUN mode, and that the network connection between the WinCC PC and PLC is active. Check for IP address conflicts on the network.

WinCC archive database becomes unavailable or archiving stops

Check the Windows Services console to verify that the SQL Server (WinCC) service is running. Check available disk space on the drive hosting the WinCC project and database files.

Restart the SQL Server service if it has stopped. Free up disk space if the drive is full, or configure WinCC archive segmentation to limit database size. Run a database consistency check using SQL Server Management Studio if data corruption is suspected.

WinCC project opens in Graphics Designer but screens do not display correctly at runtime

Check for missing or broken picture references in the WinCC Graphics Designer. Verify that all ActiveX controls and WinCC add-ons required by the project are installed on the runtime PC.

Reinstall any missing WinCC options or ActiveX components. Ensure the WinCC version on the engineering and runtime PCs match. Re-compile and transfer the project if migrating from a different WinCC version.

Alarms are not being logged or displayed in the WinCC Alarm Control

Check the WinCC Alarm Logging editor to verify that alarm classes and message blocks are correctly configured. Confirm that the SQL Server archive for alarm logging is online and accessible.

Correct the alarm logging configuration in WinCC Alarm Logging. Restart the WinCC runtime after configuration changes. If the alarm database is corrupted, back up and recreate the alarm archive segment.
