6.3 Alarms
6.3.1 Diagnostic alarms
Actions after a diagnostic alarm
There can be more than one diagnostic alarm at the same time. Each diagnostic alarm
initiates the following actions:
• The ERROR LED of the interface module flashes.
• Diagnostics are reported as diagnostic interrupts to the CPU of the IO controller and can be
read via data records.
• Incoming diagnostic alarms are saved to the diagnostic buffer of the IO controller.
• (S7-300/400) The diagnostic interrupt OB is called. If the diagnostic interrupt OB (OB82) is
not available, the IO controller goes into STOP mode.
You can find additional information in the STEP 7 online help.
