Product Info
Description
This project provides a complete PLC program for a box sorting conveyor system, developed in Siemens TIA Portal V15 and designed for integration with Nirtec Machines Simulator.
The system handles three different box sizes, detected via scanning stations. Based on the detected size, the PLC logic activates diverter arms to route each box to the correct output conveyor.
The installation includes a control panel (HMI/command panel) and a safety access door, allowing realistic simulation of industrial operation scenarios.
A key feature of this project is the implementation of a reusable SYSTEM Function Block (FB), responsible for:
- Start
- Stop
- manage the running state
- pilot lights
This block is designed as a standardized control structure, reusable across future projects and continuously improved.
The project is ideal for:
- PLC programmers
- Automation engineers
- Training and simulation environments
- Virtual commissioning workflows
Includes
• Complete PLC program (TIA Portal V15)
• Box sorting logic (3 sizes)
• Scanner-based detection system
• Diverter arm control logic
• SYSTEM FB (Start/Stop/Reset, running state and pilot lights management)
Installing Instruction
1. Open the project in Siemens TIA Portal V15.
2. Start Siemens PLCSIM.
3. Run NetToPLCSim and load the provided configuration file.
4. Connect NetToPLCSim to the PLCSIM instance.
5. Open Nirtec Machine Simulator and load the machine model.
6. Link PLC variables with simulator signals using the provided drivers.
7. Run the simulation and operate the system via the control panel.
The system is now ready for testing and simulation.
