# Industrial Pick-to-Light Control System
An advanced Pick-to-Light (PTL) system implementation using IEC 61131-3 structured text programming with MQTT integration for industrial automation applications.
## 🚀 Features
- Real-time control of 4 PTL stations with color-coded feedback
- MQTT-based communication for distributed system integration
- Automated error detection and recovery system
- Color-coded visual feedback system:
- Green: Active pick location
- Red: Error indication (wrong pick)
- Timer-based state management
- Comprehensive debug monitoring
- Industrial I/O interface integration
## 📋 System Requirements
### Software Requirements
- CODESYS Development System V3.5 or later
- [CODESYS MQTT Library](https://github.com/stefandreyer/CODESYS-MQTT)
- Network connectivity for MQTT communication
### Hardware Requirements
- PLC/Controller compatible with CODESYS Runtime (**TBEN-S2-2COM-4DXP** Controller from **Turck**)
- 4 PTL110S-FF100TD3-QPS150 devices from Bannerengineering.
- PLC supporting IEC 61131-3 Structured Text
- MQTT Broker (tested with broker running at port 1883)
- Digital I/O capabilities for PTL hardware interface
- Network connectivity for MQTT communication
## 🔧 Development Environment Setup
1. Install CODESYS Development System
2. Install MQTT Library:
- Download the library from [CODESYS-MQTT Repository](https://github.com/stefandreyer/CODESYS-MQTT)
- In CODESYS, go to Tools → Library Repository
- Install the downloaded library
- Add library reference to your project

## 🌐 MQTT Communication
### Topics
- Publish: `Test/PTL_touch` - Reports touch events
- Subscribe: `Test/PTL_1` - Receives control commands
### Message Format
- Simple integer-based protocol
- Values 1-4 correspond to PTL stations
## 💻 Implementation Details
### Color Codes
- 0: Off
- 1: Red (Error)
- 2: Green (Active)
### State Management
- Real-time touch detection
- Automatic error state recovery (1-second timeout)
- Persistent state tracking
- MQTT state synchronization
## 🚀 Getting Started
1. Clone this repository
2. Configure your PLC development environment
3. Set up MQTT broker (default: broker.emqx.io:1883)
4. Upload the program to your PLC
5. Configure I/O mapping according to your hardware setup
## 📝 Configuration
Update the following parameters in `PLC_PRG.st`:
```pascal
URL := 'broker.emqx.io:1883' // MQTT broker address
Topic := ADR('Test/PTL_touch') // MQTT publish topic
```
