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 where we left off. We began to write some code that would allow you to resume timer operation after an interruption.
In this lesson, we will complete the code to demonstrate how to continue timing a process when the timer is again enabled. So let’s open this lesson up and resume.
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.

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 ...
In the previous lesson we discussed some ways in which to organize your thoughts and some advice on to how to tackle your program writing tasks.
In this lesson, we are going to expand on that advice and get started with the simplest portion of the program. We are going to discuss how we decid...
