In many factory environments, the need to vary the value in a single set-point exists. This need may be based on some internal programming or external action. Whatever the mechanism, in this lesson, we will start programming this function.
Our set-point change will be based on some internal timers but will be started with the press of a start button as an external action. We will discuss the I/O required to perform this task and lay down some code in our quest to accomplish this chore.
This code begins the process with the start button and the first variable set-point.
While there will be further lessons to complete the programming, let’s get started with the first portion.
In a previous lesson we discussed the need to vary the value in a single set-point. We started the lesson discussing some of the I/O that is required. We also created some code but found that we didn’t quite reach the intended goal.
In the continuation of this lesson, we will show you how to ...
In this lesson, we have a factory environment that has a conveyor, some switches that run the conveyor for different lengths of time, a stop switch, and a stack light with running and stopped lamps. We need to write a program that will run the conveyor for specified lengths of time. The timing in...
In our previous lesson, we started writing some code to in order to run a conveyor for different lengths of time based on which input switch was triggered. In this lesson, we will continue writing our program to finish our time shifting quest.
We will add some more code that changes our timer...
