Guidelines Chapter 3
Example 1: Tank
The controller uses an SFC to command the phases that run the tank (add water,
heat, add ingredients, and so forth).
Give the start command to the Add_Water equipment
phase. The P1 qualifier limits this to the first scan of
the step.
Wait until the Add_Water equipment phase
is done (complete). When the equipment
phase is done, give the reset command. The
P0 qualifier limits this to the last scan of the
step.
Start the next equipment phase.
