(1) Number of consecutive transitions
[Description]
With "execution of active step
transition 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, the number of consecutive transitions can be set.
Controls in 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.
[Errors]
These parameters are imported and checked at leading edge of PLC ready flag
(M2000).
When the value that was set is outside the setting range, the Motion SFC
parameter error (error code: 17000) will occur and the initial value is used to
control.
Ver.! : Refer to Section 1.3 for the software version that supports this function.

Remark
3
These parameters are
imported at leading edge of
PLC ready flag (M2000) and
used for control thereafter.
When setting/changing the
values of these parameters,
