18 Compact Combination Fast Analog I/O Module

Publication 1769-IN081A-EN-P - February 2007

Input Data File

For each module, slot x, words 0…3 in the input data file contain the converted

value of the module’s analog input channels. Word 4 in the input data file contains

the time stamp value corresponding to the module's last input data sampling

period. Words 5 and 6 in the input data file contain status bits for the analog input

channels. Word 7 in the input data file contains status bits for the analog output

channels. Words 8 to 9 contain the directed values of the analog output channels

(output data echo).

The bits are defined as follows:

• SGN = Sign bit in 2’s complement format.

• Nu = Not Used. Bit set to 0.

• SIx = General Status bit for input channels 0…3.

• OIx = Over range flag bits for input channels 0…3.

• UIx = Under range flag bits for input channels 0…3.

• HIx = High Alarm flag bits for input channels 0…3.

• LIx = Low Alarm flag bits for input channels 0…3.

• SOx = General Status bit for output channels 0…1.

• OOx = Over range flag bits for output channels 0…1.

• UOx = Under range flag bits for output channels 0…1.
