Message types
For the messages, a distinction is made between the following message types:
●
Error messages
●
Warnings/notes
●
Read results
All three message types are displayed in the WBM.
Most messages of the "error message" type trigger a diagnostic interrupt on the relevant
PROFINET controller.
The following sections "Error messages" and "Error output of read results" describe all
messages, their meaning and the corresponding corrective measures.
