(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 one mode is switched to the other (the normal mode is switched to the
offset/gain setting mode or the offset/gain setting mode is switched to the
normal mode), the A/D converter module suspends A/D conversion and
switches OFF the power supply to the 2-wire transmitter.
To resume A/D conversion and power supply to the 2-wire transmitter, turn
ON the operating condition setting request (Y9) after the mode is switched to
the normal mode.
No errors.
The following program is designed to switch the A/D converter module mounted in the
position of I/O number X/Y0 to X/YF to the offset/gain setting mode when M10 is
turned ON, and to return it to the normal mode when M10 is turned OFF.
