Case study of an automotive production line run with an Industrial Shields M-Duino PLC. The PLC reads load cells, lasers and pressure devices on the stations, sends the orders to the robots and the mechanised arms, and exchanges data with a TouchBerry Pi Panel PC that runs an MQTT broker and Node-RED. Phones and tablets reach the panel over WiFi, and remote users through a VPN.

The PDF covers the challenge, the three stages (measure, command, watch), the system architecture with the signal table and the hardware used. Interactive version: automotive production line case study online.
