HMI, alarms and operator procedures
Цель: Изучить тему «HMI, alarms and operator procedures» и закрепить её практическими заданиями и самопроверкой.
2 акад. часа чтение и разбор теории, решение задач, работа со схемой или виртуальным стендом и проверка понимания.
Основной материал
Design overview with vessel, flows, temperature, level, pH, pump and valves. Add faceplates, trend page, alarm summary, batch step display and maintenance diagnostics.
Alarm rationalization sample
For each alarm specify tag, condition, priority, delay/deadband, consequence, operator action. Avoid duplicating status as alarms.
Operator procedure
Startup checklist should verify instruments healthy, valves correct, vessel available, no active trip, utilities ready. HMI does not replace field confirmation where procedure requires it.
Практическая работа
Create 12-alarm list and sketch three HMI screens: overview, trend, maintenance.
