1762-OF4 Output Data File
For each module, slot x, words 0 through 3 contain the channel output
data.
Words 0 through 3 contain the analog output data for channels 0 through
3, respectively. The module ignores the “don’t care” bits (0 through 2), but
checks the sign bit (15). If bit 15 equals 1, the module sets the output
value to 0V or 0 mA.
Words 0 through 3 contain the analog output data for channels 0 through
3, respectively. The module ignores the “don’t care” bits (0 and 1), but
checks the sign bit (15), and bit 14. If bit 15 equals 1, the module sets the
output value to 0V or 0 mA. If bit 15 equals zero and bit 14 equals 1, the
module sets the output value to 10.5V dc or 21 mA.
