Read/Response Command and Temperature Data
• Negative values are stored as 2’s complements.
• The converted temperature data CIO m+2 is stored in 16-bit binary data
(4-digit hexadecimal).
• 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-
rate 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.
