The input temperature data is converted to 4-digit hexadecimal digital data
and transmitted to the Master. If the conversion data is negative, the negative
value is expressed as the two's complement.
The four inputs occupy 4 words in the Master, as shown in the following dia-
gram. If the input type's data has 0.1 digits, the value transmitted to the mas-
ter is 10 times the actual value. (The decimal point is omitted.)

• Example 1: R type thermocouple at 1,000 ° C
1,000 converted to hexadecimal → 03E8 hex
• Example 2: U type thermocouple at 350.0 ° C
350 × 10 = 3,500 converted to hexadecimal → 0DAC hex
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.
The four inputs occupy 8 words in the Master, as shown in the following dia-
gram.
