Input Data File

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

analog values of the inputs.

The bits are defined as follows:

• SGN = Sign bit in two’s complement format

• Sx = General status bit for channels 0 through 3. This bit is set (1) when

an error (over- or under-range) exists for that channel.

• Ux = Under-range flag bits for channels 0 through 3. These bits can be

used in the control program for error detection.

• Ox = Over-range flag bits for channels 0 through 3. These bits can be

used in the control program for error detection.
