Configure PIUnits

Select the Data Archive node in either the Registered Units only view or MDB View tab. The Configuration for page appears on the right side.

PIUnit configuration involves PIUnitBatch Configuration, PIBatch Configuration and PISubBatch Configuration. The PIUnitBatch Configuration means setting up the PI points and the attributes necessary to create PIUnitBatches. The PI points should be specified for Active Point, Unit Batch ID, Product Name and Procedure Name. The other PIUnitBatch attributes that can be configured are Active Point behavior, PIBatch/PIUnitBatch/PISubBatch recovery option, Recovery time, Evaluation Delay for PIUnitBatches, Merge Consecutive and PIUnit-specific Debug messages. These attributes will take default values if they are not specified. The entire configuration information is saved as PIAliases and PIProperties in the Configuration module Name sub-module under the PIUnit.

Most of the PIUnit configuration properties concern the start and stop times of such batches.

A PIUnit is monitored by the PIBaGen interface only if the PIUnit is Registered (see Register or Unregister PIUnits). A PIUnit can be Registered or Unregistered at any time using the Batch Generator tool. This is similar to turning the Scan option ON or OFF for a traditional PI point.
