Download Phases (Foxboro DCS Only)

Download phases are run by the 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 during batch processing, the batch manager automatically writes (downloads) all parameter values to the control system.

Note: Download 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 in history.
