Conversion-completed flag (address 19)
Address 19 is used to confirm that a conversion-enabled channel can detect
temperature correctly.
(1)
The conversion-completed flag processing
after power ON is only per-
formed once when the channel specification for conversion-enabled/dis-
abled (address
0)
is changed.
Conversion-enabled/disabled specification change from
0
to
1
:
After setting conversion-enabled and storing a detected temperature
value in the buffer, the conversion-completed flag
of its corresponding
channel is set to 1.
Conversion-enabled/disabled specification change from 1 to
0:
The conversion-completed flag of its corresponding channel is set to
0.
(2) A conversion-completed flag is provided to each channel.

The conversion-completed flag can be used
for the interlock when
reading the detected temperature value of the channel where averaging
processing is executed.
4.4.7
Type specification of a platinum temperature-measuring resistor (address 20)
This area is used
to set the type
of a platinum temperature-measuring
resistor.
(1)
When the power supply
is turned ON, the type is set to "0", indicating
the new JIS, DIN type.
(2) All channels correspond to a specified type.
