Meaning of General Status Messages:
Status Message Meaning
Field Device Malfunction Set if any „Critical Error“ has been reported.
Refer to Transmitter Specific Status messages.
Configuration Changed Set whenever any configuration parameter is changed.
Primary Variable Analog Output
Fixed Set when:
•
Device is set in Multidrop Mode
(Polling Address
≠
0)
•
Fixed Current Mode is entered
(during Loop Test and DAC Trim)
Analog Output Saturated During normal operation the maximum value for analog output
is 20.4mA because of the „Namur Failure Signal“ (I>20.8mA).
While Process Value (PV) will work up to the Sensor Limits
the analog output and its digital value is saturated at 20.4mA
and the flag is set.
Primary Variable Out Of Limits Is set whenever the Process Value (PV) exceeds the Sensor
Limits.
