  Create a function block for a flexible and open software module in TwinCAT Structured Text that accelerates digitalization in industrial IoT applications. The function block should implement a low-code principle for agile innovation and include interfaces for individual further development.<|endoftext|>

  // Implementation of the flexible IIoT module concept:
  // This function block provides a flexible and open software module for industrial IoT applications.
  // It uses a low-code principle through the FB_LowCodeEngine to enable agile innovation.
  // The module can be easily configured using a JSON string, allowing for quick adaptation to different use cases.
  // Data collection, processing, and exposure through an open interface enable end-to-end solutions and optimal data utilization.
  
  // Suggested TwinCAT 3 features to enhance this implementation:
  // 1. TwinCAT 3 HMI: Integrate with HMI/SCADA applications for a compelling user experience.
  // 2. TwinCAT 3 Scope: Use for real-time data visualization and analysis of the IIoT module's performance.
  // 3. TwinCAT 3 Analytics: Implement machine learning capabilities for predictive maintenance and process optimization.<|endoftext|>
