How to Use Timers in PLC Programming

In this video course, you'll learn how to use timers in your PLC program using easy to follow and practical PLC program examples.

Timers are used to either determine how long an event takes (i.e. time it takes to move an object from one point to another), to measure out a period that an event has to last for (i.e. the start button has to be pressed and held for 3 seconds to initiate the process) or as a delay (i.e. process B starts 5 seconds after process A ends).

This video will help beginner programmers use timers in their programs, starting with the structure of the timer, the types of timers and an example program using these timers.

  • 88.Single Start Switch PLC Program _ Part 1

    In previous lessons I wrote a PLC program for running the motor in both momentary and latched modes. In another lesson I wrote a PLC program to run and stop a heavy three phase motor and a fan with a single momentary switch. In the momentary program, there was only one switch that we could use as...

  • 89.Single Start Switch PLC Program _ Part 2

    In the previous lesson I added a parallel shortcut path to the program to be able to run the motor in the momentary mode but this didn’t help and the motor was still running in the latched mode when I pressed the switch. Now let’s see how I can modify current PLC program to be able to run the mot...
