02:P00
Enter the location #
and advance to the
second program
instruction.
The CR23X is now programmed to read the panel
temperature every 5 seconds and place the reading
in Input Storage Location 1. The program can be
compiled and the temperature displayed (note that
it is not yet storing data).

0001: 21.234
Advance to first
storage location.
Panel temp. is
21.234°C (display
shows actual
temperature so exact
value will vary).
Wait a few seconds:
01:21.423
The CR23X has read
the sensor and stored
the result again. The
internal temp is now
21.423
o
C. The value
is updated every 5
seconds when the
table is executed. At
this point the CR23X is
measuring the
temperature every 5
seconds and sending
the value to Input
Storage. No data are
being saved. The next
step is to have the
CR23X send each
reading to Final
Storage. (Remember,
the Output Flag must
be set first.)
