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 achieve varying the set-point with a timing interval. The external action will begin the temperature varying graph that we are looking for.
So let’s open it up and see how we accomplished varying our temperatures.
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...
On some occasions, you may need to continue timing a process even after the enable input to the timer turns false. As you may know, once the timer enable input transitions from false to true again, the timer resets and begins timing from zero. In this lesson, we will show you how you can change t...
