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.

Input Data conversion examples
Unit: 0.1°C K or J ×10 500.0°C → 5000 → 1388 hex
−20.0°C → −200 → FF38 hex
−200.0°C → −2000 → F830 hex
