Caution! CPU and MC modules also have hardware registers that can be set using the #DO and #AO
data addresses. Writing to these registers will cause the CPU or MC module to behave unpredictably and
should be avoided.

Description
#AIss.1 to 8 0-32760
Read Analog input channels 1 to 8. Uses a 12-bit analog to digital converter.
Analog values are stored as 16-bit numbers by left shifting the number
by 3 bits and adding a leading sign bit (not used). Analog values are
thus stored in the RTU as a number from 0 to 32760 (maximum value is
32767 minus 7 as the lower 3 bits are not used and are set to 0).
Hardware Overview
Hex Values: The raw
values of the inputs (0-
32760) converted to the
Hexadecimal number
format.
