Factory Acceptance Test (FAT) Explained – Part 3 | PLC Analog I/O Test

Overview

This video continues the Factory Acceptance Test (FAT) series, focusing on testing PLC digital inputs and outputs (I/O).

It demonstrates how to verify that all field signals are correctly connected and functioning as expected by simulating input signals and observing corresponding outputs.

Digital I/O testing is a critical step in FAT to ensure that the control system responds correctly and that all wiring and configurations are properly implemented before delivery.
