Temperature Sensor Units
Section 7-5
Example 4
Temperature:
Open circuit (
°
F)
Temperature Data: 7FFF FFFF
Note
(1) Leftmost digits are stored in the lower memory addresses. Treat the data
in the lower memory address as the leftmost digits when programming.
(2) Be sure that the data is read at least once every 125 ms to allow for the
CPU Unit’s cycle time and communications time. Correct data may not be
obtained if the read cycle is greater than 125 ms.
Programming Example
The following programming example shows how to use 2-decimal-place Mode
for the following PC configuration.
In this example, 100 times the temperature data for temperature input 0 is
stored in binary form in D100 to D102.
