CCST 32 — Alarm State Propagation to HMI

Briefing

Three field alarms (FAULT_A, FAULT_B, FAULT_C) should set a single HMI_ALARM_ANY bit (OR of all). A separate ALARM_COUNT INT should track how many are active.

Objectives

• HMI_ALARM_ANY := FAULT_A OR FAULT_B OR FAULT_C
• ALARM_COUNT := count of TRUE faults (0-3)
