GT1-TS04T and GT1-TS04P Temperature Input Units
Converted Data
152
Normal Mode
The input temperature data is converted into 4-digit hexadecimal (binary) data
and stored in one of the four words in the Master allocated to temperature
input as shown below.

If the converted data is a negative number, it is stored as a two's complement.
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. Some
examples are provided in the following table.
Input
Unit: 1 K (0.0 to 500.0 C),
J (0.0 to 400.0 C),
T and L (0.0 to 400.0 C),
Pt100, JPt100
Unit: R, S, K (–200 to 1300 C),
0.1 J (–100 to 850 C),
L (–100 to 850 C),
B
Two-decimal-point Mode
The input temperature data for all input types and input ranges is sent to the
Master as a value with 2 digits after the decimal point. The value of the tem-
perature data is multiplied by 100 and converted to 8-digit hexadecimal digital
(double-precision binary) data. If the converted data is a negative number, it is
expressed as a two's complement. The four input points are allocated eight
words in the Master as shown below.

Example: 850.00 C x 100 = 85000; Converted to binary = 00014C08 Hex.
Thus, leftmost data: 4C08 Hex., and rightmost data: 0001 Hex.
