PLC Automated Car Project

PLC Automated Car Project

For my final automation project this semester, we had to use a PLC (Programmable logic controller) to accomplish a complicated task. With six technical directors in the class, we had to have one go button that would start a chain of events through all six PLCs twice. Below is my part of the project.

This project is designed to move a toy car around a track after a red,
yellow, green LED progression and a go buzzer sounds. When the
PLC receives the signal from the PLC before it in line, it will start the LED
progression then start the car running around the track. Once the car has
made one revolution around the track it will signal the first loop of the track
to stop and the next PLC in line to start. When the signal from the next PLC
is received the PLC will change the active track to a jumping track, start the
LED progression again, and then send the car down the new track. When
the car makes one revolution around the new track it will signal the PLC to
stop the new loop and the next PLC in line to start.
