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.
