Where:
O = Output - O0 corresponds to output 0, O1 corresponds to output 1
F = Overload fault bits - 1 = fault present; 0 = no fault
FR = Fault reset bit - 1 = reset output; 0 = no change
I = Input
C = Counter value for input 15
CR = Counter reset
CF = Counter fast - where 1 = fast input (raw data), 0 = standard input filtered data
FT = Input Filter Time for input channels
1794-OB16PXT uses outputs 0...3
(1)
The unused lower byte in read word 1 floats during operation. Do not use this byte for fault status. See
