Downtime
What is it?
The Downtime Manager is the FactryOS module that records and classifies production stops on your equipment. It combines automatic detection from PLC signals and shift calendars with manual operator input to build a complete picture of when equipment was not running, and why.
Why does it matter?
Without structured downtime registration, production losses stay invisible or get misattributed. You can't improve what you can't measure. The Downtime Manager gives operators, shift supervisors, and plant managers a shared, accurate record of every stop, its cause, and its duration. This is the foundation for meaningful OEE analysis and for prioritizing improvement actions.
How does it fit in the system?
The Downtime Manager sits on top of the equipment model in FactryOS. It connects to:
- Factry Historian for real-time signals (PLC alarms, speed tags, state signals)
- Shift calendars for planned stop detection
- Production orders for change-over detection
Each piece of equipment can have a state transition table assigned to it. That table defines how raw signals map to downtime states. When a stop is detected, it is linked to a downtime reason from a reason tree that is assigned per equipment. Users interact with detected events through the Downtime Overview screen.
