Diagnostics alarms
Diagnostic alarms are transferred as diagnostic interrupts. The PROFIBUS device
identification number is required for identifying a diagnostic interrupt.
The HCS4200 has the identification number 81C4.
The evaluation in SIMATIC is performed via I/O_FLT1 (OB82) and RALRM (SFB54).
Structure of the diagnostics alarm
