■ 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 speci c to each input type: °C

for temperature, Volts for voltage, and % for potentiometer. The data are 32-bit oating 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, de ned 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 de ned 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
