[Program Example]
(1) This program reads 2 comments associated with steps being activated at the SFC block No.1
when X1 is turned ON, and stores those to the storage device after D0. (The number of
comment to be read in a single scan is also set in 2.)
The interlock ladders to perform "batch write of SFC program in RUN status" or "write of
comment file in RUN status" are included in the following program.
aX0 & bSM735

[Procedure for "batch writes of SFC program in RUN status" or "write of comment file in RUN status"]
1) Turns ON the X0 (write execution command in RUN status).
2) M0 (write enable flag in RUN status) is turned ON when SP.SFCTCOMR instruction is
deactivated.
3) Turns OFF the X0 (write execution command in RUN status).
4) Performs "batch write of SFC program in RUN status" or "write of comment file in RUN
status".
5) Turns OFF the M0 (write enable flag in RUN status) with test mode of GX Developer.
6) SP.SFCTCOMR instruction is executed again when M0 (write enable flag in RUN status) is
turned OFF.
