· We can implement state diagrams seen in earlier sections using many of the advanced function discussed in this section.
· Most PLCs allow multiple programs that may be used as subroutines. We could implement a block logic method using subroutine programs.
· Consider the state diagram below and implement it in ladder logic. You should anticipate what will happen if both A and C are pushed at the same time.
