9 OPERATION FOR MOTION SFC AND PARAMETER
No. Item
In the main cycle after PLC ready flag
(M2000) ON, the program is executed from
the initial (first) step in accordance with the
number of consecutive transitions of the
normal task.
1 Start control
After that, the program is executed continuously by the number of consecutive transitions of the normal task in the
Motion CPU main cycle. (The settings of "executed task" and "number of consecutive transitions" of the subroutine
called program are invalid. It is controlled as the normal task.)
Ends the self program.
END control
2 Again, the program is started by the Motion SFC start request (D(P).SFCS) from the PLC or by a subroutine call/start
END
(GSUB) made from the Motion SFC program.
No. Item
At occurrence of a valid event after PLC
ready flag (M2000) ON, the program is
executed from the initial (first) step in
accordance with the number of consecutive
transitions of the corresponding program.
1 Start control
The program is executed continuously by the number of consecutive transitions of the corresponding program each
time an event occurs. (The subroutine called program is controlled in accordance with the "executed task" and
"number of consecutive transitions" of the call source program.)
END control
2 As specified for END operation.
END
(1) Start setting
[Description]
The following control is changed by "automatically started or not" setting.
 Program run by normal task
When "automatically started"
 Program run by event task
When "automatically started"
When "not automatically started"
The program is started by the Motion SFC start request (D(P).SFCS)
from the PLC or by a subroutine call/start (GSUB) made from the
Motion SFC program.
 When started by the Motion SFC start request (D(P).SFCS)
In the main cycle after execution of the Motion SFC start request
(D(P).SFCS), the program is executed from the initial (first) step in
accordance with the number of consecutive transitions of the normal
task.
 When subroutine started
In the (next) main cycle after execution of GSUB, the program is
executed from the first step in accordance with the number of
consecutive transitions of the normal task.
 When subroutine called
The program is executed in the same cycle from the first step.
When "not automatically started"
The program is started by the Motion SFC start request (D(P).SFCS)
from the PLC or by a subroutine call/start (GSUB) made from within
the Motion SFC program.
 When started by the Motion SFC start request (D(P).SFCS)
At occurrence of an event after execution of the Motion SFC start
request (D(P).SFCS), 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 an 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.
