INPUT REGISTERS DESCRIPTION
(1) ANALOG INPUT IN % (30001 to 30016; 30001 to 30008 for J3)
Indicates analog input values in percentage for each channel (1 – 16; 1 – 8 for J3).

(2) ANALOG INPUT IN ENGINEERING UNIT (30017 to 30048; 30017 to 30032 for J3)
Indicates analog input values in engineering unit for each channel (1 – 16; 1 – 8 for J3). The unit is specific to each input
type: °C for temperature, Volts for voltage, and % for potentiometer. The data are 32-bit floating values, which requires two
consecutive registers for one module.
(3) CHANNEL STATUS (30081 to 30096)
Indicates the current status of analog inputs (1 – 16; 1 – 8 for J3). The following list shows the names and descriptions of
each bit.

Input Overrange
Indicates the designated analog input is in overrange, defined as one or
more of the following condition:
• ADC input value 0x0000 or 0xFFFF
• Burnout status for thermocouple, RTD and Potentiometer input
• Out of range defined in the temperature table (thermocouple and RTD)
• ADC error
0 : Normal
1 : Overrange
7
ADC Error
Indicates the status of ADC.
0 : Normal
1 : Error
12
Cold Junction Compensation SW
Indicates whether the cold junction compensation is enabled or disabled,
for thermocouple input.
0 : Disable
1 : Enable
Others
