Utility
Alarms v1
Description

Alarms

Provides a prioritized, latched alarm indication with up to 15 priority levels.

Alarms are sequentially acknowledged with the highest priority acknowledged first.

If the alarm input is no longer active, that priority level alarm latch is reset when acknowledged and the next-highest priority alarm is indicated next.

The function block indicates the alarm priority, whether any alarm is currently active, and whether any alarm is latched.

If more than 15 alarm priority levels are required, the function blocks may be cascaded. The following signal flow diagram shows three function blocks with highest priority level 45. The concept can easily be expanded further.
