11 MOTION SFC PARAMETER
POINT
Since the execute task can be set for every Motion SFC program No., multiple
programs need not be written for single control (machine operation) to divide
execution timing-based processing’s.
For example, it can be achieved easily by subroutine starting the areas to be run
in fixed cycle and to be run by external interrupt partially in the Motion SFC
program run by the normal task.
(3) Number of consecutive transitions
[Description]
Set the number of consecutive transitions to program executed by the event or
NMI task for every program.
Refer to Section "11.4 Task Parameters" for number of consecutive transitions.
[Errors]
This program parameter is imported when the PLC ready flag (M2000) turns off
to on, and is checked at starting of the Motion SFC program (automatic start,
start from PLC or subroutine start).
When the value is illegal, either of the following Motion SFC errors is set and
the initial value is controlled.
