Data Phases (Batch Management Only)

Data phases are processed by the AVEVA Batch Management System. They have no phase control or status tags for handshaking with the control system and do not require operator acknowledgement. They do not have control button capability but do allow formula parameter assignments. When a data phase is encountered during batch processing, the Batch Manager automatically writes (downloads) all parameter values to the control system.

Note: Data phases are intended to be used to write a target value to a controller. If the process model has only parameter target tags created, the target value is written to both the Target and Actual in history. If Actual tags have been created in the process model, the Actual value from the controller is written to history.
