9 OPERATION FOR MOTION SFC AND PARAMETER
When the NMI task is set, multiple interrupt inputs among the external
interrupts (for NMI task) can be set.
<Example> Interrupt setting: Inputs for NMI task I0, I1, I2, I3, I4, I5
Motion SFC program No. 10 – NMI : I0
Motion SFC program No. 20 – NMI : I1 + I2
Motion SFC program No. 30 – NMI : I5
[Errors]
This program parameter is imported at leading edge of PLC ready flag (M2000),
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 Motion SFC parameter error (error code:
17010) will occur and it is controlled with initial value.
POINT
(1) 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 processes.
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.
(2) Set a large fixed cycle than the motion operation cycle after confirming the
motion operation cycle.
(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 "9.11 Task Parameters" for number of consecutive transitions.
[Errors]
This program parameter is imported at leading edge of PLC ready flag (M2000),
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 Motion SFC parameter error (error code:
17001, 17002) will occur and it is controlled with initial value.
