Examples
The following three examples demonstrate the three types of execution control
possible with step programming. Example 1 demonstrates sequential execu-
tion; example 2, branching execution; and example 3, parallel execution.
The following process requires that three processes, loading, part installation,
and inspection/discharge, be executed in sequence with each process being re-
set 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.
