Evaluation Delay

Use the Evaluation Delay to specify the time that the interface should wait before it evaluates the values from the PI points specified above. The PIUnitBatch starts at the time the Active Point indicates the start of the PIUnitBatch. However, other attributes of PIUnitBatch - Unit Batch ID, Product Name, Procedure Name, PIBatch, PIBatch Product Name, and PIBatch Recipe Name are evaluated after waiting for the number of seconds specified in Evaluation Delay.

If a PIUnitBatch end event is received while the interface is waiting for the evaluation delay to elapse, the PIUnitBatch properties are evaluated at the end event time and the PIUnitBatch is started and stopped. If the option Evaluate at the end of each UnitBatch is selected, then the attributes are evaluated at the end of the PIUnitBatch and the Evaluation Delay value specified is ignored. The default value for Evaluation Delay is 0 seconds.
