In manufacturing, it is fairly common for a production line to be running, but not actually producing parts or finished goods as part of a work order or product code run. Examples of this may be when the line is being run during scheduled maintenance to verify work has been performed to a satisfactory level. There are times when a line may be running as part of new product introduction or testing, or times when operator training is occurring. When the line is getting ready for a production run, there may be a period of time that the line is in a changeover or setup mode, and there may be times during a production run, when the line mode changes back to setup say after a fault, and material has to be run back through the extruder cell.
In OEE 2.0, it is now possible to define modes that the line or equipment may be in and you can define whether production counts should be included during these modes or used in OEE calculations. Modes allows for a more granular analysis of equipment utilization; how much time does a line spend in maintenance, training, changeover, setup, while still allowing the equipment states of running, blocked, idle, faulted to be captured. As production counts and equipment cycles are captured in all modes, you can still use these counters to determine run hours on equipment, strokes on die sets etc., that may drive maintenance scheduling and other activities.
Default Equipment Modes are provided for Changeover, Cleaning, Disabled, Idle, Maintenance, Other, and Production. Custom modes can also be added. The OEE Equipment Manager component is used to manage equipment mode class, state and schedule.
