Equipment manager component by default has an equipment state class named Default. The default class consists of the following default states.
This checkbox (True, checked by default) causes any new State added to the class to have its Override Current Line Line Downtime checkbox initialized as True (checked). Checking or unchecking this box does not cause any existing child State to have its override setting changed.
This property is available on the MES Equipment State Class Object for use via scripting.
Refer to Override Current Line Downtime below for further details on the override feature.
If you expand the Equipment State Class folder you can see the existing states.
Valid State Types are...
Enter in the integer value for this equipment state. This will generally align with the status code value from the PLC.
Do not set state code to zero, since zero is used internally.
The Assigned Codes list provide a view of all codes that have already been assigned.
Enter in a time value in seconds for how long a state must persist for before it considered to be in this. The Short Stop Threshold is not used for states of state type RUNNING.
Down Time events can be prevented from affecting OEE Availability for a set duration of time (Short Stop Threshold). Events that occur during the Short Stop Threshold period will be ignored for ongoing OEE Availability calculations. To have all events be included in OEE Availability calculations, set Short Stop Threshold = 0.
Note: This setting only affects the Key Reason detection methods, Cell Priority and Neighbor Priority.
This property is available on the MES Equipment State Object for use via scripting.
When enabled, this state will be included in the calculation of Mean Time Between Failure (MTBF), when this state is responsible for causing a line downtime event. MTBF is calculated by taking total running time, or time during a run in which the line is not down, and dividing it by the number of applicable events. So if a production run had 3.5 hours of running time and had 5 events for which Meantime Metrics were enabled, the MTBF would be 0.7. MTBF is pertinent for unexpected downtime events or Unplanned Downtime Type states.
The Override property defines if it is possible for a operator to override the equipment state through the Downtime Table Editor component. Valid options are...
