Temperature Sensor Units
Section 7-5
Example 1
Example 2
Converted Temperature Data
The temperature data will be stored in the input words allocated to the Tem-
perature Sensor Unit in 4-digit hexadecimal.
”m” is the last input word allocated to the CPU Unit, Expansion I/O Unit, or
Expansion Unit connected immediately before the Temperature Sensor Unit.
• Negative values are stored as 2’s complements.
• Data for range codes that include one digit after the decimal point are
stored without the decimal point, i.e., 10 times the actual value is stored.
• If the input temperature exceeds the range that can be converted, the
converted temperature data will be held at the maximum or minimum
value in the range.
• If the input temperature exceeds the range by more than a specified
amount, the open-circuit detection function will detect an open-circuit and
the converted temperature data will be set to 7FFF.
The open-circuit detection function will also operate if the cold junction
compensator is faulty.
• The open-circuit detection function will be automatically cleared and nor-
mal input temperature conversion will begin automatically when the input
temperature returns to the convertible range.
