11.5 Adjusting diagnostic information
11.5.1 Classification of diagnostics messages
More detailed information on the current diagnostics messages displayed is provided in the
DIAG/Diagnostics list menu.
In accordance with Namur specification NE 107, the diagnostics messages are characterized by:
• Message number
• Error category (letter in front of the message number)
–
F
= (Failure) a malfunction has been detected
–
C
= (Function check) (No error)
Maintenance work is being performed on the device. Wait until the work has been
completed.
–
S
= (Out of specification) The measuring point is being operated outside its specification
Operation is still possible. However, you run the risk of increased wear, shorter operating
life or lower accuracy levels. The cause of the problem is to be found outside the measuring
point.
–
M
= (Maintenance required) Action should be taken as soon as possible
• Message text
If you contact the Service Department, please cite the message number only. Since you can
individually change the assignment of an error to an error category, the Service Department
cannot use this information.
11.5.2 Adjusting diagnostic behavior
All the diagnostics messages are assigned to specific error categories at the factory. Since other
settings might be preferred depending on the application, error categories and the effect errors
have on the measuring point can be configured individually. Furthermore, every diagnostics
message can be disabled.
Example
The controller returns diagnostics message 531 "Logbook full". You want to change this message
so that an error is not indicated on the display for example.
