Diagnostic messages of the electronic modules
Actions after a diagnosis message
Each diagnostic message triggers the following actions:
● The SF LED of the interface module lights up.
● Several simultaneous diagnostic messages are possible.
● Diagnostics data are reported as diagnosis interrupts and can be read from data records.
● Following a diagnostic message, they are saved to the diagnostics buffer of the I/O
● OB 82 is called. If OB 82 is not available, the I/O controller goes into STOP.
● Acknowledgment of the diagnostic interrupt (thereafter a new interrupt is possible).
Causes of faults and corrective measures
The causes of errors and corrective measures for the diagnostics messages are described in
this manual in the chapter entitled "Channel diagnostics" under "Interrupt, cause and system
messages to the PROFINET IO."
