Data Formats and I/O Ranges
B.1 Analog Input Formats
The ADAM analog input modules can be configured to transmit data to
the host in Engineering Units.
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, milli- volts, 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 charac- ters.
The data format is a plus (+) or minus (-) sign, followed by five decimal
digits and a decimal point. The input range which is employed deter-
mines the resolution, or the number of decimal places used, as illustrated
in the following table:
