(1) Function
Switches the mode of the A/D converter module .
• Normal mode to offset/gain setting mode (th e offset/gain setting mode status
flag (XA) turns ON)
• Offset/gain setting mode to normal mode (th e offset/gain setting mode status
flag (XA) turns OFF)
POINT
(1) When the offset/gain setting mode is swi tched 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 swit ched to the normal mode, the A/D
converter module holds the previous operatio n condition and resumes
operation automatically under the previous operation con dition.
(2) Operation error
No errors.
