3.2.5 Conversion starting time setting function (Q66AD-DG only)
(1) As the A/D conversion starting time, set the "time necessary from when the used
2-wire transmitter powers on until its output stabilizes".
This setting allows A/D conversion processing to be started as soon as the output of
the 2-wire transmitter stabilizes.
(2) Set the time to the CH Conversion starting time setting (for 2-wire transmitter)
(Un\G78 to Un\G83).
(3) The following indicates the time until the A/D conversion completed flag (Un\G10)
turns ON when the A/D conversion starting time has been set.
(Conversion starting time) + (A/D conversion pre-processing: Approx. 150 to 165ms)
+ (A/D conversion processing: number of conversion enabled channels 10ms)
Set the A/D conversion starting time in consideration of the time necessary from
when the 2-wire transmitter powers on until its output stabilizes and the warm-up
time of the 2-wire transmitter.
