Fault Detection
Open circuit indicator light and status byte
A range warning is issued when a channel input is outside the rated input value. Warning bits stay on after out of range bits are set. An out-of-range bit is set when a channel input exceeds the rated input value by 2.4%. Out of range bits are also set if inputs drop below 0.5V (1 ... 5V mode) or 2.08 mA (4 ... 20 mA mode)
