Phase process diagram

This diagram is an example of a phase process:
FTB_PCD Programmers phase process diagram
  1. The command to START the phase is issued from the
    FactoryTalk Batch
     Server. The RUNNING program eventually begins.
  2. The phase logic sends a request to download the AMOUNT parameter from the
    FactoryTalk Batch
     Server.
  3. The
    FactoryTalk Batch
     Server requests a Promise ID from the Material Server. This establishes an accounting data entity for tracking the inventory used.
  4. The Material Server returns SUCCESS for the Promise ID to the
    FactoryTalk Batch
     Server. This is used by the
    FactoryTalk Batch
     Server during warm restarts to restore the state of a batch if the
    FactoryTalk Batch
     Server failed as the batch was running.
  5. The
    FactoryTalk Batch
     Server downloads the parameters to the phase logic. The PCD runs its program to perform a material addition or distribution.
  6. The FEED_COMPLETE and ACTUAL_AMOUNT parameters are uploaded to the
    FactoryTalk Batch
     Server.
  7. The phase logic transitions to a terminal state.
  8. The value returned in the FEED_COMPLETE report parameter, and the Hold on Split Feed configuration determine what recipe execution will do next:
    TIP:
    Hold On Split Feed is set in the
    Material Policy
     tab in the
    Server Options
    dialog box in
    FactoryTalk Batch Equipment Editor
    .
    • If FEED_COMPLETE is TRUE, the batch continues running.
    • If FEED_COMPLETE is FALSE, and Hold on Split Feed is YES, the batch is held.
    • If FEED_COMPLETE is FALSE, and Hold on Split Feed is NO, the batch continues running.
  9. The amount of the material addition or distribution is sent to the Material Server. The inventory levels in the material database are updated, and for material additions, the sublot or sublots of inventory used are identified.
  10. Material, lot, and container data are returned to the
    FactoryTalk Batch
     Server and recorded in the
    FactoryTalk Batch
     Event Journal.
