Case study of an end-of-line test bench run by an M-Duino 42 PLC. It reads the serial number from a barcode reader, drives each wire of a harness and reads every end, decides OK or KO and stores one line per test on the microSD card, with the serial number as the key. The wiring and the figures on the page are an example.

The PDF covers the challenge, the stages (scan, test, decide, record), the system architecture with the signal list and the hardware used. Interactive version: end-of-line testing case study online.
