Word 5 PU FP CF 0 Reserved 00000BDDN0
Word 6 0000P1P00000V1V0W1W0U1U0
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 o and 1 respectively.
