Description
Additional information

The Siemens 6AV6371-2BD18-0AJ0 is a WinCC (Windows Control Center) runtime software license belonging to Siemens' SIMATIC HMI software family. It is a PC-based SCADA and HMI visualization software package designed for industrial process monitoring, control, and data acquisition on standard Windows-based hardware platforms. This part number corresponds to a specific WinCC runtime license configuration, enabling operator interface functionality on industrial PCs and standard PCs within automation environments.

WinCC offers a comprehensive set of features including tag-based licensing, integrated alarm management, trend displays, and historical data archiving. It supports a wide range of communication interfaces and drivers for connecting to SIMATIC S7 PLCs via PROFIBUS, PROFINET, MPI, and Industrial Ethernet, as well as OPC DA/UA connectivity for third-party system integration. The software includes a powerful scripting environment (VBScript and C-Script), a graphics designer for creating process screens, and supports redundant server configurations for high-availability applications.

WinCC runtime software is widely deployed in process industries such as chemical, pharmaceutical, water treatment, and power generation, as well as in discrete manufacturing environments including automotive assembly and machine tool operations. Its scalability from single-station installations to distributed multi-client/server architectures makes it suitable for both small standalone HMI applications and large plant-wide SCADA systems. The software integrates natively with the Siemens TIA Portal engineering framework and the broader SIMATIC automation ecosystem.

Common Error Codes & System Events

Event ID: 1000000: WinCC runtime startup failure — the runtime application could not be initialized correctly.
Check Windows Event Viewer for underlying OS errors. Verify that all required WinCC services are running and that the license key is valid and properly installed.
Event ID: 1001: Tag communication error — one or more configured tags cannot be read from the connected PLC or data source.
Verify the communication channel configuration, check PLC connection status, confirm correct IP address or PROFIBUS address, and ensure the PLC program is running.
Event ID: 2501: License not found or license count exceeded — the number of configured tags exceeds the licensed tag count, or no valid license is detected.
Check the installed license using the Siemens Automation License Manager (ALM). Install the correct license or upgrade to a higher tag count license.
Event ID: 1003: Alarm logging database error — WinCC cannot write to or read from the alarm archive database.
Check available disk space, verify SQL Server service is running, and confirm that the WinCC project database is not corrupted. Run a database consistency check.
Event ID: 2000: Redundancy switchover event — the active WinCC server has failed and the standby server has taken over.
Investigate the cause of the primary server failure. Check network connectivity, hardware status, and WinCC service logs on the primary server before attempting switchover back.
Event ID: 1100: OPC server connection lost — WinCC has lost communication with a configured OPC DA or OPC UA server.
Verify the OPC server is running and accessible on the network. Check firewall settings, DCOM configuration (for OPC DA), and OPC UA endpoint configuration.
Event ID: 3000: Script runtime error — a VBScript or C-Script action has encountered an unhandled exception during execution.
Open the WinCC Script Debugger, identify the failing script and line number, and correct the script logic. Check for null object references or invalid tag accesses.

Frequently Asked Questions

What is the tag capacity of the 6AV6371-2BD18-0AJ0 WinCC license?

The 6AV6371-2BD18-0AJ0 corresponds to a specific WinCC runtime license tier. The tag count for this part number should be verified against the Siemens SIMATIC WinCC ordering data, as WinCC licenses are available in multiple tag count variants (e.g., 128, 512, 2048, 65536 tags). Consult the Siemens product catalog or the Automation License Manager for confirmation.

Is this WinCC license compatible with TIA Portal?

Yes, SIMATIC WinCC runtime licenses are compatible with the Siemens TIA Portal engineering environment. WinCC can be configured and managed within TIA Portal as part of an integrated automation project.

What operating systems are supported by this WinCC runtime software?

SIMATIC WinCC supports Microsoft Windows operating systems, specifically industrial-grade versions such as Windows 10 IoT Enterprise and Windows Server editions. Refer to the Siemens compatibility matrix for the exact supported OS versions for this release.

Can WinCC communicate with third-party PLCs or systems?

Yes, WinCC supports OPC DA and OPC UA standards, allowing communication with third-party PLCs and automation systems that provide OPC-compatible servers. Additional communication drivers may be required for specific third-party protocols.

Does this license support a multi-client/server architecture?

SIMATIC WinCC supports distributed multi-client/server architectures, including redundant server configurations. The specific capabilities depend on the license type and configuration; a WinCC server license is required for server functionality.

Troubleshooting

WinCC runtime fails to start after installation or Windows update

Check the Windows Event Viewer (Application and System logs) for error messages related to WinCC services or SQL Server. Verify that the Siemens Automation License Manager shows a valid, active license.

Ensure all WinCC prerequisites are installed, including the correct Microsoft SQL Server version. Re-activate the license via the Automation License Manager and restart the WinCC runtime services. If a Windows update caused the issue, check Siemens compatibility notes for that update.

Tags show invalid or no values in the WinCC runtime display

Open the WinCC Channel Diagnostics tool to check the status of communication channels. Verify the PLC is online and reachable via the configured network interface (ping the PLC IP address or check PROFIBUS diagnostics).

Correct the channel configuration in WinCC (IP address, rack/slot number, or PROFIBUS address). Ensure the correct communication driver is installed and that no firewall or network switch is blocking the connection. Restart the affected communication channel.

Alarm archive or trend data is not being recorded

Check that the Microsoft SQL Server service (used by WinCC for archiving) is running. Verify available disk space on the drive where the WinCC project and archives are stored.

Restart the SQL Server service if it has stopped. Free up disk space if the drive is full. Check WinCC archive configuration settings and ensure the archive tags are correctly assigned. Run the WinCC database consistency check tool if corruption is suspected.

WinCC reports a license error or runs in demo mode

Open the Siemens Automation License Manager (ALM) and check whether a valid WinCC runtime license is present and assigned to this machine. Demo mode is activated automatically when no valid license is detected.

Transfer or install the correct WinCC runtime license using the Automation License Manager. If using a USB dongle, ensure it is properly connected. If the license was previously on a failed hard drive, contact Siemens for license recovery procedures.

WinCC client cannot connect to the WinCC server

Verify network connectivity between the client and server PCs. Check that the WinCC server runtime is active and that the Windows Firewall is not blocking WinCC communication ports. Confirm the client is configured with the correct server name or IP address.

Add WinCC application exceptions to the Windows Firewall on both client and server. Ensure both machines are on the same Windows domain or workgroup with appropriate user permissions. Reconfigure the WinCC client project with the correct server connection settings.
