5.4.1
Conversion-enabled/disabled specifications (address
0)
Address
0
is used to designate whether temperature detection is executed or not.
(1)
When the power is turned ON, the channel specification is set at
" 0 0 0 0 ~ "
for conversion-disabled for all channels.
(2)
Conversion-enabled/disabled can be changed by the sequence program
to reduce sampling time.
i
To specify channels 1, 3, and
4
for conversion
i
By writing
OOODH
(1 3) to specify channels for conversion-enabled/disabled,l
:
the sampling time
is obtained as 40 msec
x
3 = 120 msec.
