(a) Restores the offset/gain values of the user range setting stored in the CPU to the
A/D converter module.
(b) There are two types of interlock signals for the G(P).OGSTOR instruction: the
completion device (D) and the status display device at completion (D) + 1.
1) Completion device
Turns ON in the END processing of the scan where the G(P).OGSTOR instruc-
tion is completed, and turns OFF in the next END processing.
2) Status display device at completion
Turns ON and OFF depending on the completion status of the G(P).OGSTOR
instruction.
Normal completion : Stays OFF and does not change.
Abnormal completion: Turns ON in the END processing of the scan where the
G(P).OGSTOR instruction is completed, and turns OFF in the next END
processing.

*1 When the G(P).OGSTOR instruction is executed, A/D conversion is not performed. After the com-
pletion device (D) turns ON, A/D conversion starts, the A/D conversion value is stored into the buffer
memory, and the A/D conversion completed flag (XE) then turns ON.
(c) When the offset/gain values are restored, the reference accuracy falls to about
less than three times of the accuracy before that.
In any of the following cases, an error occurs and the corresponding error code is
stored into the completion status area (S)+1.

Execution completion of
the G.OGSTOR instruction
Case resulting in operation error
The G(P).OGSTOR instruction was executed in the offset/gain setting
mode.
The G(P).OGSTOR instruction was executed consecutively.
The G(P).OGSTOR instruction was executed for the model that differs
from the model for which the G(P).OGLOAD instruction had been exe-
cuted.
