PLC-Based Color Sorting Conveyor
Conveyor control logic and operator screens were designed in Siemens PLC and SIMATIC HMI to sort blue, green, and other products.

What it does
This course project designed control logic for a conveyor that sorts products into three paths by color. Two sensors identify blue and green items; everything else continues to a third path.
Control flow
The ladder logic covers start/stop and emergency-stop states, sensors, pushers, and conveyor timers. Counters for each color are shown on the operator screen; a new item restarts the relevant belt timer.
Operator screen
The SIMATIC HMI design brings together system and belt controls, color counters, reset buttons, and operating states. The source report documents the design and screens, but does not provide measured performance from a physical conveyor line.
