• SGN = Sign bit in two’s complement format.
• UU = Unlatch under-range (or low clamp exceeded) alarm.
• UO = Unlatch over-range (or high clamp exceeded) alarm.
Input Data File
For each module, slot x, input data file words 3…10 contain the state of the
module’s output data (output data echo) file words 0…7. During normal
operation, these input words represent the analog values that the outputs are
directed to by the control program.
