Rate and floods.
How many alarms an operator gets in ten minutes, and how often a flood buries the screen.
A cold room drifts, a conveyor jams, a dock door stays open. DigiOS raises each one once, with a priority and an owner, and walks up an escalation ladder until somebody answers. Shelving needs a reason and a time limit. Everything that is not an alarm is a notice, and notices are summarised.
Every alarm has its cause, its consequence, the corrective action, the time to respond and a priority, written down before it ever sounds.
Each alarm has one source: the PLC's own alarm, a device, or a rule over several readings. The same condition never raises two alarms.
Acknowledging logs your name and the time, and never clears the cause. First-out marks the alarm that started a trip, and a flood is counted and grouped instead of scrolling past.
A shelved alarm carries a reason and a time limit. It sits in its own list, and it comes back by itself when the time is up.

If the owner doesn't answer, the next person is called, then the shift supervisor. The ladder is set per alarm and per shift, so a cold-room excursion at 3 a.m. goes to whoever holds the night.
Nothing sits between a raise and the person who must act. Groupings and summaries only order and annotate what a person sees.
The numbers a review needs, kept as the alarms happen.
How many alarms an operator gets in ten minutes, and how often a flood buries the screen.
Alarms standing unanswered, and alarms that raise and clear again and again.
The alarms that account for most of the noise, so you rationalise those first.
Yes, by shelving it with a reason and a time limit. It is listed while it is shelved, and it returns on its own.
No. A PLC alarm stays the one source, and DigiOS adds the priority, the owner and the ladder.
They are notices, with a priority and an owner, summarised on the schedule your team picks.
We'll set up the alarm summary and the ladder for the equipment involved.
