Note
Data will be undefined if default values are set using the CX-Integrator or
other Support Software.
Temperature Input Units have two Display Modes: normal and 1/100 display.
The input temperature data is converted to 4-digit hexadecimal digital data
and transmitted to the Master Unit. If the conversion data is negative, the neg-
ative value is expressed as the two's complement.
Four words are allocated in the Master Unit for the four inputs, as shown in the
following diagram. If the data for the input type contains a digit below the dec-
imal place, the value sent to the master will be 10 times the actual value. (The
decimal point is omitted.)
The input temperature data for all input types is transmitted to the Master as
data with precision to 0.01 digits. The temperature data is multiplied by 100
and converted to 8-digit hexadecimal digital data (four long values).
If the conversion data is negative, the negative value is expressed as the two’s
complement.

• Example 1: R type thermocouple at 1,000°C
• Example 2: U type thermocouple at 350.0°C
1,000 converted to hexadecimal → 03E8 hex
350 × 10 = 3,500 converted to hexadecimal → 0DAC hex
