7.3 Interrupts
Denition
The fail-safe analog input module F-AI 8xI 2-/4-wire HART HA supports diagnostic interrupts and
maintenance messages.
A diagnostic interrupt is an alarm that reports activated events of a device status to the system
operator with the appropriate operator authorization (maintenance and service).
Diagnostic interrupts are used by the I/O module to output both diagnostic messages and
maintenance events.
Diagnostic interrupts
The F-module generates a diagnostic interrupt for each diagnostic message described in section
"Diagnostic messages (Page 67)".
The following table provides an overview of the diagnostics interrupts of the F-module. The
diagnostics interrupts are assigned either to one channel or to the entire F-module.
