Modeling the Equipment for OEE
The importance of modeling a line correctly based on the factors below drives the usability and usefulness of any production data or metrics generated.
If a production line of many cells is modeled simply as a single cell, then features provided by the OEE module such as downtime detection methods, cell cycle time, aggregation of machine states by cell, and visual aspects of the OEE components such as the OEE Time chart is diminished.
Things to consider:
- Type of Line (single machine, simple contiguous process, parallel processes, shared cells across lines, complex sub-lines, primary cells, cell groups within cell groups)
- Line Downtime Determination (When is the line considered to be down? All cells, any cells, particular cell)
- How production is scheduled (if parts of a line are scheduled separately from each other, then they may be considered two separate lines)
- Interface to cell (if a cell has no real-time accessible interface, its state and output may be combined with an adjacent cell)
- Reporting for the Line (What do I need to report on and show to users?)
Create a production Equipment Model in the MES Equipment Manager.
Ensure to:
- Define your Enterprise, Sites, Areas, Lines and Cells based on the type of line.
- Activate your equipment to execute analysis and collect tag values for use in production.
- Set up Line Downtime Detection Method to define how line downtime is determined.
- Connect states and counts from the equipment PLC interface to the production model.
Once an operation is running on a line, the line cannot be deleted until the operation is completed.
