Default Production and Util/OEE Refresh Rate Attributes

The Default Production Rate attributes are used to calculate the utilization and performance of corresponding entities.

The Default Production Rate values are written to the MES database by running Entity Model Builder. There is no run-time functionality with these attributes. When written to the database, these values will overwrite the existing values in the database for the entity. Therefore, you should run Entity Model Builder only when the entity is not running a job that might have set these rates to a different value.

• Rate

  The default production rate for the entity. The default value is 1.0.

  The default production rate must be greater than 0. An entry of 0 will cause an error.

• Rate Unit of Measure

  The default unit of measure for the production rate. The default is hours/batch.

  • hours/batch (the default)

  • minutes/batch

  • seconds/batch

  • batches/hour

  • batches/minute

  • batches/second

• Batch Size

  If using batches during production, enter the default batch size. The default is 1.

  The batch size cannot be 0.

  The decimal place resolution of the batch size is controlled by the system parameter Maximum number of decimals for batch entry. For information about setting this parameter, see the MES Client User Guide or online help.

• Util/OEE Refresh Rate

  At run time, OEE information is retrieved from MES and displayed via current OEE, Performance, Quality, and Utilization attributes.

  The OEE information is updated within the attributes at a time interval defined by this attribute. The minimum refresh rate is 15 seconds. The default value is 00:01:00.0000000 (1 min).

  Although a refresh rate can be specified, if no new data is available from MES within the specified interval, the values will not be updated until a subsequent scan when new data is available.
