Building a PLC Program Part 4 – Traffic Light

by

In part 1, we looked at writing PLC programs to control a traffic light using discrete bits and timed sequencing using indirect addressing. Part 2 used indirect addressing for inputs and output to control the program’s sequence of pneumatic (air) cylinders. Part 3 returned to the traffic light application and expanded our program significantly. We … Read more
