Cards in this group · 4
- Y2.04.1An alarm message should name the object, the deviation, and the first safe action, not just a code

- Y2.04.3A message that only says fault or abnormal leaves the operator guessing from memory, not procedure
- Y2.04.4Whether an alarm is actionable should be settled before commissioning, not patched tag by tag after
