Initialization
command for
the RTD
input module
Request for
operation of the
reading function
block when it
has not been
operated

Specifying the
type or RTD
Indicating the error
status during initialization
function block execution
Indicating the run
channel during initialization
function block execution.
Base No.
Slot No.
Used
channel
Indicating the error
status during
reading function
block execution
Turns "On" when
error occurs at the
used channel
The detected
temperature value
of channel 0
The digital
conversion value of
channel 0
The
temperature
detection is
normally
finish ed at
the RTD
input module
Turns "On"
when error is
detected at
the used
channel
%Q0.3.2 turns on when the
detected temperature value of
centigrade is negative, and the
negative is converted into
positive.
In this routine, the data type of the
detected temperature value is
integer , so that it is covered into
BCD data type to be displayed to the
digital BCD value is output %Q0.2.0
to %Q0.2.19.
In this routine, the data type of the
detected temperature value is
integer, so that it is covered into
BCD data type to be displayed to
the digital BCD value is
output %QD0.4.0~%QD0.4.19.
This routine
converts the
detected
temperature value
into a value of
Fahrenheit
%Q0.3.0 turns "On" when the temperature
converted into a value of Fahrenheit and a
negative is converted into a positive
