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.
