Proline Prowirl F 200 PROFIBUS PA Diagnostics and troubleshooting
Hauser 147
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.
For local display with touch control: the background lighting changes to red.
Warning The device continues to measure. The measured value output via PROFIBUS
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 the Analog Input, Digital Input and Totalizer function blocks are configured for cyclic
data transmission, the device status is coded as per PROFIBUS PA Profile 3.02
Specification and transmitted along with the measured value to the PROFIBUS Master
(Class 1) via the coding byte (byte 5). The coding byte is split into three segments: Quality,
Quality Substatus and Limits.

A0032228-EN
 22 Structure of the coding byte
The content of the coding 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 PROFIBUS
Master (Class 1) via the coding byte .
Determining the measured value status and device status via the diagnostic behavior
When the diagnostic behavior is assigned, this also changes the measured value status and
device status for the diagnostic information. The measured value status and device status
depend on the choice of diagnostic behavior and on the group in which the diagnostic
information is located. The measured value status and device status are firmly assigned to
the particular diagnostic behavior and cannot be changed individually.
