Where:
PU = Power up unconfigured state
FP = Field power off
CF = In configuration mode
BD = Calibration bad
DN = Calibration accepted.
P0 and P1 = Output holding in response to Q0 thru Q1
W0 and W1 = Wire off current loop status for input channels 0 and 1 respectively. (Not used on voltage outputs.)
U0 and U1 = Underrange for input channels o and 1 respectively.
V0 and V1 = Overrange for input channels 0 and 1 respectively.
EN = Enable outputs; 0 = output follows S1/S0, 1 = output enabled
IC = Initiate configuration bit
TR = Transparent bit
IT = Interrupt toggle bit
Q0 and Q1 = Request for outputs to hold
RV = Revert to defaults bit
QK = Quick calibration
CK = Calibration clock
GO = Gain offset select

Underrange for 4Ć20mA occurs in the blind area below 0 (3.2mA).
2 < and > indicate the overrun beyond actual range (about 5%).
