System Architecture

This educational project demonstrates a decoupled, multi-project architecture designed to teach software engineering principles and industrial automation concepts.

• ScadaGUI (WPF Application): The primary user interface demonstrating MVVM (Model-View-ViewModel) design pattern. This component teaches students about modern desktop application development, data binding, and event-driven programming. It subscribes to events from the DataConcentrator to learn about real-time UI updates.

• DataConcentrator (Core Logic): The central processing unit that demonstrates industrial data acquisition concepts. This educational component shows:

  • How to poll external data sources at configurable intervals
  • Real-time alarm evaluation and threshold monitoring
  • Database integration for event logging
  • Event publishing patterns for loose coupling
  • Configuration management and data persistence

• PLCSimulator (Data Source): A simulated Programmable Logic Controller that teaches students about industrial automation concepts. This educational tool:

  • Demonstrates background threading and continuous data generation
  • Simulates realistic industrial sensor behavior
  • Shows I/O address mapping concepts
  • Provides hands-on experience with industrial data formats

• Database (Persistence Layer): Uses SQL Server LocalDB to teach database concepts and Entity Framework integration. The educational database design includes:

  1. Tags: Demonstrates configuration data modeling
  2. Alarms: Shows relationship modeling and constraint concepts
  3. ActivatedAlarms: Teaches historical data logging and audit trails

Application Interface

This educational project demonstrates a modern WPF interface with five main tabs, each designed to teach specific aspects of industrial process monitoring and control systems.

Tags Management Tab

The Tags tab demonstrates the fundamental concept of data point configuration in SCADA systems, teaching students how to manage different types of industrial data sources.

Educational Concepts:

• Tag Types: Teaches four fundamental industrial data types:

  • DI (Digital Input): Binary state from field devices (switches, sensors)
  • DO (Digital Output): Binary commands to field devices (lights, relays)
  • AI (Analog Input): Continuous values from sensors (temperature, pressure, flow)
  • AO (Analog Output): Continuous commands to actuators (valves, motors)

• Dynamic UI Design: Demonstrates conditional UI rendering based on data types:

  • Common Properties: Name, Description, I/O Address
  • Input Properties: Scan Time (ms), On/Off Scan toggle
  • Analog Properties: Low/High Limits, Units (°C, %, PSI, etc.)
  • Output Properties: Initial Value for system startup

• Input Validation: Shows proper data validation techniques and error handling patterns

Alarm Management Tab

The Alarms tab teaches students about industrial alarm systems and process monitoring concepts.

Educational Concepts:

• Alarm Configuration: Demonstrates how to create and manage alarms for Analog Input tags
• Threshold Monitoring: Shows Above/Below trigger conditions and limit setting
• Message Management: Teaches custom alarm message definition and management
• Data Relationships: Illustrates how to link alarms to specific data sources

Real-Time Monitoring Tab

The Monitor tab demonstrates real-time data visualization and control concepts in industrial systems.

Educational Concepts:

• Real-Time Data Binding: Shows how to display live data updates in WPF grids
• Manual Control Interface: Teaches direct control of output devices with validation
• Event-Driven Updates: Demonstrates real-time alarm display and notification systems
• System Status Monitoring: Illustrates comprehensive process visibility and control

Alarm History Tab

The Alarm History tab teaches students about historical data analysis and audit trail concepts.

Educational Concepts:

• Historical Data Management: Demonstrates how to store and retrieve historical alarm records
• Event Logging: Shows timestamping and detailed event information storage
• Data Analysis Patterns: Teaches how to analyze historical trends and patterns
• Audit Trail Implementation: Illustrates compliance and troubleshooting data requirements

Reports Tab

The Reports tab demonstrates automated report generation and data analysis concepts.

Educational Concepts:

• Report Generation: Shows how to create automated reports from historical data
• Performance Analysis: Teaches data analysis techniques for identifying optimal operation periods
• Mathematical Calculations: Demonstrates formula implementation (high_limit + low_limit) / 2 ±5
• File Management: Illustrates timestamped file creation and organization techniques

Generated Report Example

This example demonstrates the output format and analysis capabilities of the educational reporting system.
