Sequence program created by using the PC CPU
It is not necessary to create a sequence program to turn a bit device ON
and OFF.
Using a sequence program to turn a bit device set by this function ON
or OFF is not recommended.
If the bit device turned ON by the SET function is turned ON by a
sequence program (SET, OUT instruction, etc.), it cannot be confirmed
on which side the bit device was turned ON.
When a touch panI or operation panel is used. the current key input can
be confirmed by a sequence program by means of a G-controller buffer.
(See Sction 5.15.)

Restrictions when creating monitoring screens

which a bit device is turned ON and OFF.
