12.6 Adapting the diagnostic information
12.6.1 Adapting the diagnostic behavior
Each item of diagnostic information is assigned a specific diagnostic behavior at the
factory. The user can change this assignment for specific diagnostic information in the
Diagnostic behavior submenu.
Expert → System → Diagnostic handling → Diagnostic behavior
Available diagnostic behaviors
The following diagnostic behaviors can be assigned:
Diagnostic behavior Description
Alarm The device stops measurement. The totalizers assume the defined alarm
condition. A diagnostic message is generated.
Warning The device continues to measure. The measured value output via PROFINET
and the totalizers are not affected. A diagnostic message is generated.
Logbook entry only The device continues to measure. The diagnostic message is displayed only in
the
Event logbook submenu ( Event list submenu) and not in alternation with
the operational display.
Off The diagnostic event is ignored, and no diagnostic message is generated or
entered.
Displaying the measured value status
If modules with input data (e.g. Analog Input module, Discrete Input module, Totalizer
module, Heartbeat module) are configured for cyclic data transmission, the measured
value status is coded as per PROFIBUS PA Profile 3.02 Specification and transmitted along
with the measured value to the PROFINET Controller via the status byte. The status byte is
split into three segments: Quality, Quality Substatus and Limits.

 44 Structure of the status byte
The content of the status byte depends on the configured failsafe mode in the particular
function block. Depending on which failsafe mode has been configured, status information
in accordance with PROFIBUS PA Profile Specification 3.02 is transmitted to the the
PROFINET controller via the status byte. The two bits for the limits always have the value
0.
