Local automation without internet
Critical routines, manual override and safety limits should run on-site. The cloud is for history, alerts and remote access.
NORRIS // KNOWLEDGE
Engineering knowledge base
Practical explanations about physical infrastructure, automation, networks and operations.
Backup power
Calculate load and required runtime first, then select the UPS, batteries and the order for shedding non-critical loads.
Access and attendance
The door circuit controls physical access, the terminal identifies people, and attendance rules turn events into a timesheet.
Cold-room monitoring
Beyond a chart, you need verifiable sensors, alarm thresholds and delays, door state, connectivity, backup power and a response procedure.
