€ 2.495,00
The Siemens 6AV6381-2BU07-5AH0 is a software license package belonging to the SIMATIC WinCC flexible product family, developed by Siemens for engineering and configuring HMI (Human-Machine Interface) applications. This part number corresponds to a WinCC flexible 2008 SP4 or a comparable runtime/engineering edition, used to create visualization projects for SIMATIC HMI panels and PC-based operator stations. It is part of Siemens' established SCADA and HMI engineering software portfolio, designed to run on standard Windows-based engineering PCs.
WinCC flexible provides a comprehensive engineering environment with tag management, alarm logging, trend displays, recipe management, and script-based automation. It supports a wide range of communication drivers enabling connectivity to SIMATIC S7-200, S7-300, S7-400, and S7-1200 PLCs via MPI, PROFIBUS DP, and Industrial Ethernet (PROFINET). The software includes tools for multi-language project configuration, structured project libraries, and simulation capabilities that allow offline testing of HMI screens without physical hardware.
This software package is used across a broad range of industrial sectors including manufacturing, automotive, food and beverage, chemical processing, and water treatment. It is typically deployed to configure operator panels such as the SIMATIC TP, OP, MP, and Mobile Panel series, enabling plant operators to monitor and control production processes. Its compatibility with the broader SIMATIC automation ecosystem makes it a standard engineering tool for system integrators and OEMs working within Siemens-based control architectures.

Common Error Codes & System Events
- Event ID: 1000001
- Communication error between WinCC flexible runtime and the connected PLC. The configured communication driver cannot establish a connection.
Verify PLC connection parameters (IP address, MPI address, or PROFIBUS address). Check physical network cabling and ensure the PLC is powered and in RUN mode. - Event ID: 1000002
- Tag read/write error. A configured tag cannot be read from or written to the PLC.
Confirm the tag address exists in the PLC program. Check data type consistency between the HMI tag configuration and the PLC variable. - Event ID: 1000011
- Runtime license not found or license is invalid. WinCC flexible runtime cannot start without a valid license.
Install or transfer a valid WinCC flexible runtime license using the Siemens Automation License Manager (ALM). Ensure the license matches the runtime version and panel type. - Event ID: 1000020
- Project download failed. Transfer of the HMI project to the target panel or PC was interrupted or unsuccessful.
Check the transfer connection (USB, Ethernet, or MPI). Ensure the target device is in transfer mode and that the project is compiled without errors before downloading. - Event ID: 1000030
- Alarm buffer overflow. The number of pending alarms exceeds the configured alarm buffer capacity.
Acknowledge and clear active alarms. Increase the alarm buffer size in the project settings or review alarm configuration to reduce unnecessary alarm generation. - Event ID: 1000040
- Recipe data error. A recipe record could not be read from or written to the configured data source.
Verify recipe tag assignments and ensure the associated PLC data blocks are correctly configured and accessible. Check for data type mismatches in recipe variable definitions. - Event ID: 1000050
- Script runtime error. A VBScript or function within the HMI project encountered an execution error.
Review the script logic in the WinCC flexible engineering environment. Check for division by zero, invalid tag references, or unsupported function calls and correct accordingly.
Frequently Asked Questions
Which PLC families are compatible with WinCC flexible 6AV6381-2BU07-5AH0?
WinCC flexible is compatible with SIMATIC S7-200, S7-300, S7-400, and S7-1200 PLCs, communicating via MPI, PROFIBUS DP, or PROFINET/Industrial Ethernet depending on the PLC and panel hardware used.
Which HMI panels can be configured using this software?
This software supports the full range of SIMATIC HMI panels including the TP (Touch Panel), OP (Operator Panel), MP (Multi Panel), and Mobile Panel series. Panel compatibility depends on the specific software edition and version installed.
Is a separate runtime license required in addition to the engineering license?
Yes, a separate WinCC flexible Runtime license is required to run the configured project on a PC-based operator station. For dedicated SIMATIC HMI panels, the runtime is typically included with the panel hardware.
Can WinCC flexible projects be migrated to TIA Portal WinCC?
Yes, Siemens provides a migration tool within TIA Portal that allows WinCC flexible projects to be imported and converted. Some manual rework may be required depending on the complexity of the original project.
Does WinCC flexible support simulation without physical hardware?
Yes, WinCC flexible includes an integrated simulator that allows HMI projects to be tested on the engineering PC without a physical panel or PLC connection, enabling offline validation of screen layouts and logic.
Troubleshooting
WinCC flexible runtime fails to communicate with the PLC after project download
Check the communication settings in the project, including the PLC IP address, MPI node address, or PROFIBUS address. Verify that the correct communication driver is installed on the engineering PC or panel.
Correct the connection parameters in the WinCC flexible project under 'Connections'. Ensure the network interface card or communication module is properly configured and that firewalls or antivirus software are not blocking the communication port.
License error displayed on startup of WinCC flexible engineering software
Open the Siemens Automation License Manager (ALM) and check whether a valid WinCC flexible engineering license is present and not expired or transferred out.
Install a valid license using the ALM tool. If the license was on a USB dongle or another PC, transfer it back to the current machine. Contact Siemens license support if the license cannot be recovered.
Project compilation fails with tag or address errors
Review the compiler output log in WinCC flexible for specific error messages referencing tag names, data types, or screen objects. Identify misconfigured or missing tag addresses.
Correct all flagged tag addresses to match the actual PLC variable addresses. Ensure data types are consistent between the HMI tag table and the PLC program, then recompile the project.
HMI panel displays 'No connection to PLC' message during runtime
Verify physical network or bus connections between the panel and PLC. Check that the PLC is powered on and in RUN or STOP mode, and that the panel's IP or bus address matches the project configuration.
Restore physical network connectivity, correct any IP address or bus address conflicts, and ensure the PLC program is running. Restart the HMI runtime after resolving the connection issue.
Alarms are not displayed on the HMI panel despite PLC conditions being met
Check the alarm configuration in WinCC flexible, including the trigger tag, trigger bit, and alarm class settings. Verify that the alarm view or alarm window object is correctly placed on the relevant screen.
Correct the alarm trigger tag address and ensure the alarm class is active and not suppressed. Confirm the alarm display object is configured to show the relevant alarm classes and is visible during runtime.
