5.10 Y/N transition
Use the "SHIFT Y/N transition", "WAIT Y/N transition" when the route needs to be
branched according to the establishment of the shift conditions.

(1) Description of operation
(a) The operation is shifted to the lower step when the shifting conditions set by
Gn are established, and to the step connected from right when the shifting
conditions are not established.
(b) The difference between "SHIFT Y/N" and "WAIT Y/N" is the same as that
between "SHIFT" and "WAIT".
(c) This allows the following selective branch program to be described easily.
The G0 program and G1 program are limited only when
the affirmation/negation of conditional expression is
different.
<Conventional description>
G0
G1
IFB1
(Example 1)
[G 0]
M0
[G 1]
!M0
(Example 2)
[G 0]
D0!=K100
[G 1]
D0==K100
<Current description>
G0
IFB1
Set the G0 program shown in the above (Example 1) and
(Example 2).
The converted SFC program list code is the same as the
conventional description. (Only the SFC diagram
expression differs.)
Consequently, the program in which the part of "Automatic
search Conditional expression of vacant G-No." is
logically negated, is created automatically, causing two G-
programs to be occupied.
