Analog Output Module 15

Publication 1762-IN016D-EN-P - June 2013

• UOx = Under-range flag bits for output channels 0…3. These bits indicate an input

signal below the user range. They can be used in the control program for error detection.

The module continues to convert analog data to the minimum full range value while this

bit is set (1). The bit is reset (0) when the error clears.

Output Data File

For each module, slot x, words 0…3 contain the channel output data.

Words 0…3 contain the analog output data for channels 0…3, respectively. The module ignores

the “don’t care” bits (0…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…3 contain the analog output data for channels 0…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.
