9 MOTION SFC PARAMETER

9.2 Number of Consecutive Transitions and Task Operation

9.2.1 Number of consecutive transitions

With "execution of active step
processing performed when condition enables (transition of active step)" defined as a
single basic operation of the Motion SFC program execution control in the execution
cycle of the corresponding task, this operation is performed for the number of active
steps to terminate processing once. And the same operation is processed continuously
in the next cycle.
In this case, the transition destination step is executed in the next cycle when the
transition condition enables.
Consecutive transition control indicates that transition destination steps are executed
one after another in the same one execution cycle when their transition conditions
have enabled (single basic operation is performed consecutively).
In this case, set the number of consecutive transitions.
Control exercised is common to the Motion SFC programs executed by normal tasks.
POINT
Set the number of consecutive transitions to the Motion SFC programs executed
by event and NMI tasks for every program.
