9.2.2 Diagnostic messages of the electronic modules
Actions after a diagnosis message
Every diagnostic message leads to the following actions:
● The SF LED on the interface module is lit.
● There can be more than one diagnostic message at the same time.
● Diagnostics data are reported as diagnosis interrupts and can be read from data records.
● Following a diagnostic message, the message is saved in the diagnostic buffer of the I/O
controller.
● Next, OB 82 will be called. If OB 82 is not available, the I/O controller goes to STOP
mode.
● Acknowledgment of the diagnostic interrupt to enable new interrupts.
