End Step
This expresses the end of an SFC main program. An SFC main
program requires either this ‘end step’ or the ‘SFC end’ of (5). The
end step has the same step number as the initial step. When the
immediately preceding transition condition is satisfied, the initial
step returns to the active state.
ssss = Initial step number (0-2047)
(7)
Sequence Selection (divergence)
This transfers the active state to 1 step in which the transition
condition is satisfied out of multiple connected steps. When the
transition conditions are satisfied simultaneously, the step on the
left has priority. (The number of branches is a maximum of 5
columns).
(8)
Sequence Selection (convergence)
This collects into 1 step the paths diverged by above (7).
