FFactorySim - Industrial Device Simulator

Simple industrial device simulator with OPC UA integration for IoT demonstration.

Features

• Device Management: Add, remove, rename devices
• Production Control: Start/stop devices, adjust production rate
• Error Simulation: Emergency Stop, Power Failure, Sensor Failure
• Real-time Monitoring: Temperature, Good/Bad Count, Workorder ID
• OPC UA Integration: Full server implementation with Azure Line Controller compatibility

Technologies

• .NET Framework, WPF, MVVM Pattern
• OPC UA communication
• Data binding and custom converters

Installation

Requirements

• Windows 10/11
• .NET Framework 4.7.2+
• Visual Studio 2019/2022

Run

1. Open FFactorySim.sln in Visual Studio
2. Build solution (Ctrl+Shift+B)
3. Run application (F5)

Usage

Basic Operations

1. Add Device: Click "Add Device" button
2. Edit Name: Double-click device name or click pencil icon
3. Control Production: Use ON/OFF button and +10/-10 rate controls
4. Simulate Errors: Check error checkboxes in "Error Status" section

OPC UA Configuration

• Endpoint: opc.tcp://localhost:4840/
• Namespace: 2
• Nodes: ProductionStatus, ProductionRate, DeviceError, Temperature, GoodCount, BadCount
• Methods: EmergencyStop(), ResetErrorStatus()

OPC UA Access

Write Access: Only ProductionRate node supports external write access with automatic bounds checking (0-100%).

Methods: EmergencyStop() triggers emergency stop, ResetErrorStatus() clears all device errors.

Other nodes are read-only and updated internally by the simulation engine.

Architecture

• SimulationEngine: Device simulation
• FactoryOpcServer: OPC UA server
• FactoryMainViewModel: Main ViewModel
• FactoryDeviceModel: Device data model
