APPENDIX
(1) Functions
(a) Reads the offset/gain values of the user range setting of the A/D converter
module to the CPU.
(b) There are two types of interlock signals for the G.OGLOAD 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.OGLOAD
instruction 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.OGLOAD instruction.
Normal completion : Stays OFF and does not change.
Abnormal completion: Turns ON in the END processing of the scan
where the G.OGLOAD instruction is completed,
and turns OFF in the next END processing.

(3) Program example
The following program is designed to read the offset/gain values of the A/D
converter module mounted in the position of I/O number X/Y0 to X/YF when M11
is turned ON.
