The following three examples demonstrate the three types of execution con-
trol possible with step programming. Example 1 demonstrates sequential
execution; example 2, branching execution; and example 3, parallel execu-
tion.
The following process requires that three processes, loading, part installa-
tion, and inspection/discharge, be executed in sequence with each process
being reset before continuing on the the next process. Various sensors
(SW1, SW2, SW3, and SW4) are positioned to signal when processes are to
start and end.
