PLC/SCADA controls pumps, valves, oxygen and alarms. In intensive systems automation is a process-safety issue: pump trips, oxygen shortage or biofilter faults can escalate in minutes.
What should be documented?
- Recipes for day/night and peak feed.
- Emergency mode: oxygen, bypass, alarm chain.
- Who receives alarms (SMS/app) and how to act.
- Tested fail-safe modes and backup-power linkage.
See sensors, backup power and oxygen supply — automation without measurement and reserve is incomplete.
