Sequential Control (Turn On and Off in Sequence Continuously)
This type of automation application is similar to the 3rd application we 
have introduced. They are both sequential control applications. For exam-
ple 3, DO channel will keep its value after it is turned on. In example 8 
here, after DO channel is turned on, it will be turned off after a specific 
time. You can see the time chart for this application by Figure 7.37 below. 
There is one time base needed to control the digital output sequential 
action. In this example, the period of the time base to turn off one DO and 
turn on the next-door DO is 1 second.
