Measurement range underflow
0:
The “Show measurement underrange” diagnosis is deactivated or the
temperature value or field-side input voltage is above the
temperature/voltage lower limit.
1:
The temperature value or field-side input voltage is below the
temperature/voltage lower limit.
Overrange
Measurement range overflow
0:
The “Show measurement overrange” diagnosis is deactivated or the
temperature value or field-side input voltage is below the
temperature/voltage upper limit.
1:
The temperature value or field-side input voltage is above the
temperature/voltage upper limit.

Underrange
User limiting value underrange
0:
The “Show underrange of user range values” diagnostics is deactivated or
the temperature value or field-side input voltage is above the user-defined
temperature/voltage lower limit.
1:
The temperature value or field-side input voltage is below the user-defined
temperature/voltage lower limit.
User Overrange
User limiting value overrange
0:
The “Show overrange of user range values” diagnostics is deactivated or
the temperature value or field-side input voltage is below the user-defined
temperature/voltage upper limit.
1:

Wire Break
Wire break
0:
The “Show wire break” diagnostic is deactivated or there is no wire break.
1:
“Show wire break” is activated and there is a wire break.
General Error
Group error
0:
There is no error or bit 0 (underrange), bit 1 (overrange) and bit 5 (wire
break) is/are not set.
1:
There is a general error; bit 0 (underrange), bit 1 (overrange) or bit 5 (wire
break) is set.
