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 maximum or minimum value in the
temperature input range that has been set by ±20
°C or ±20°F, the dis-
played value will be held.
• If the circuit is disconnected, the open-circuit detection function will oper-
ate and the converted temperature data will be set to 7FFF.
• 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.
Input Data conversion examples
Unit: 1°C K or J 850°C → 0352 hex
−200°C → FF38 hex
Unit: 0.1°C K, J, Pt100 or
JPt100
×10 500.0°C → 5000 → 1388 hex
−20.0°C → −200 → FF38 hex
−200.0°C → −2000 → F830 hex
