7. MODBUS
IMS01J02-E2

Data whose decimal point’s presence and/or position depends on input
range
The position of the decimal point changes depending on the input range type because the Modbus
protocol does not recognize data with decimal points during communication.
The following data can have one of three decimal point positions:
No digit below decimal point, 1 digit below decimal point, 2 digits below decimal point
For details, see
Input range table (P. 107).
The input range for voltage/current input
(H-TIO-H/J module) and H-SIO-A module is fixed at 0.0 to 100.0 %.

Example: When the temperature set value is -20.0
°
C, -20.00 is processed as -200,
-200 = 0000H - 00C8H = FF38H
