Input Image
The input image file represents data words and status bits. Input
words 0…3 hold the input data that represents the value of the analog
inputs for channels 0…3. These data words are valid only when the
channel is enabled and there are no errors. If time stamping is
enabled, Word 4 in the input data file contains the time stamp value
that corresponds to the module's last input-data sampling period.
Input words 5 and 6 hold the general status bits for each input
channel as well as the high and low alarm and over-range and
under-range bits. To receive valid status information, the input
channel must be enabled.
