Appendix B Data Formats and I/O Ranges
B.5 Analog Output Formats You can configure ADAM analog
output modules to receive data from 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 milliamps. The
Engineering Units format is readily parsed by the majority of computer
languages as the total data string length is fixed at six characters: two
decimal digits, a decimal point and three decimal digits. The resolution
is 5
µA.
Example: An analog output module on channel 1 of slot 0 in an
ADAM-5000 system at address 01h is configured for a 0 to 20 mA
range. If the output value is +4.762 mA, the format of the Analog
Data Out com- mand would be #01S0C14.762<cr>
