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 the timer timing value based on whether or not the timer completed its original timing function.
Let’s assume that you need the timer to time for 20 seconds in order to complete a defined step in your program however, the timer input was interrupted prior to completion and the step only timed for 9 seconds. We show you how to manipulate the timer parameter in order to complete the full 20 seconds without starting from the beginning of the timing process.
As you know, when the timers enable input transitions to false, you will lose the timers accumulated value. In the previous lesson, we discussed the need to retain a timer’s accumulated value when the timers enable input transitions from true to false so that we can finish the timing process wher...
There may be an occasion when you need to use a single switch in the field as both a start and stop command. In this lesson, we will demonstrate exactly how to use a switch first to start a single motor and then once the motor is running, use the same switch to stop the motor.
You will also se...
In previous lessons we demonstrated how to vary the time value in a timer using three separate switches and some move instructions. In this lesson, we are going to accomplish the exact same task but using only a single switch.
We will run the conveyor for 5 seconds with the first press, then ...
