11 MOTION SFC PARAMETER
No. Item
At occurrence of a valid event after starting of the
PLC ready flag (M2000), the program is executed
from the initial (first) step in accordance with the
number of consecutive transitions of the
corresponding program.
1 Start control
After that, the program is executed continuously by the number of consecutive transitions of the corresponding
program at occurrence of a valid event.
END control
2 As specified for END operation.
END
• Program run by NMI task
When "automatically started"
[Errors]
None.
POINT
In the case of the program which is executed by the normal task, write the
program so that it is not ended by END but it returns to the starting step by a
jump when starting of the automatically from an initial again.
When "not automatically started"
The program is started by the Motion SFC start instruction
( S(P).SFCS ) from the PLC or by a subroutine call/start
(GSUB) made from within the Motion SFC program.
• When started by the S(P).SFCS instruction
At occurrence of a valid event after execution of the
S(P).SFCS instruction, the program is run from the initial
(first) step in accordance with the number of consecutive
transitions of the corresponding program.
• When subroutine started
At occurrence of a valid event after execution of GSUB, the
program is executed from the first step in accordance with
the number of consecutive transitions of the corresponding
program.
• When subroutine called
The program is executed immediately from the first step.
