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%).
