The ADAM analog input modules can be configured to transmit data
to the host in Engineering Units.
Data can be represented in Engineering Units by setting bits 0 and 1 of
the data format/checksum/integration time parameter to 0.
This format presents data in natural units, such as degrees, volts,
millivolts, and milliamps. The Engineering Units format is readily
parsed by the majority of computer languages because the total data
string length, including sign, digits and decimal point, does not exceed
seven characters.
The data format is a plus (+) or minus (-) sign, followed by five
decimal digits and a decimal point. The input range which is em-

used, as illustrated in the following table:
