(1) Function

Switches the mode of the A/D converter module.

• Normal mode to offset/gain setting mode (the offset/gain setting mode status

flag (XA) turns ON)

• Offset/gain setting mode to normal mode (the offset/gain setting mode status

flag (XA) turns OFF)

POINT

(1) When the offset/gain setting mode is switched to the normal mode, Module

Ready (X0) turns from OFF to ON.

Note that initial setting processing will be executed if there is a sequence

program that makes initial setting when Module Ready (X0) turns ON.

(2) When the offset/gain setting mode is switched to the normal mode, the A/D

converter module holds the previous operation condition and resumes

operation automatically under the previous operation condition.

(2) Operation error

No errors.
