Downtime

Downtime is typically the biggest production loss when looking at the components of OEE. It is a major concern for most manufacturers, because lost capacity can never be regained. Machine downtime is often manually recorded on paper or in a spreadsheet. This can lead to poor accuracy and can make it difficult to analyze and drive improvements.

Infor MES Downtime functionality works in these modes:

Automatically

Through a connection to the equipment using a PLC.

Operators are alerted in real-time when there is a downtime on the operator dashboard. If the PLC knows the reason code for the downtime then these are captured automatically, if the reason code is unknown then the operator explains the downtime from the dashboard.

Manually

Enabling operators to record downtimes in real-time or to enter it retrospectively at the end of the job or shift.

Downtime is any time that machines in the factory are not running, typically for these reasons:

• Production stops: When no production order is being executed on a production line
• Machine stops: When an individual machine is stopped

It is common for machine stops to overlap with production stops.
