2 Interrupt setting
Set whether the event

(I0 to I15).
Event task
These parameters are imported
when PLC ready flag (M2000)
turns off to on and used for control
thereafter.
When setting/changing the values
of these parameters, turns the
PLC ready flag (M2000) off.
(1) Number of consecutive transitions
[Description]
With "execution of active step
judgment of next transition condition
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 when the PLC ready flag (M2000)
turns off to on.
When the value that was set is outside the setting range, the following Motion
SFC error is set and the initial value is used to control.

count error
The normal task's
consecutive transition
count of the Motion SFC
program executed by the
normal task is outside the
range 1 to 30.
The initial value
of 3 is used for
control.
Turn PLC ready flag (M2000)
off, make correction to set the
value of within the range, and
write it to the CPU.
