Status Bits
Holds 16 bits of status for various
parameters in the instrument. A bit value
of “1” indicates that the associated fault
condition is present.
Bit 15 = current loop open
Bit 14 = current loop shorted
Bit 13 = power fault
Bit 12 = 5 volt fault
Bit 11 = missing sensor
Bit 10 = (not defined)
Bit 6 = configuration fault
Bit 5 = zero fault
Bit 4 = calibration fault
Bit 3 = over-range
Bit 2 = failed sensor
Bit 1 = high alarm
Bit 0 = low alarm
Examples:
Missing sensor = Bit 11 is set =
$0800
Power fault and
failed sensor = Bits 13 and 2 set =
$2004
