Configure an equipment phase

The
Equipment Phase Properties
 dialog displays equipment phase configuration information for the selected equipment phase. Use the
Configuration
tab to set up specific behaviors for the equipment phase, and to configure which routines to use for the Prestate and Fault routines.
To configure an equipment phase:
  1. From the
    Prestate
     menu, choose the prestate routine to use for this equipment phase.
    Prestate routines are optional routines that perform some failure detection, verify that all control modules are in the correct state, or execute other logic common to all state routines. This routine is executed by the equipment phase prior to the execution of any of the other state routines. When the equipment phase is in a state with no associated state routine (for example, Idle, Held, Stopped), the Prestate routine continues to execute, but no state routine executes.
  2. From the
    Fault
     menu, choose the fault routine to use for this equipment phase.
    Fault routines are optional routines that are executed by the equipment phase whenever a major fault occurs within the equipment phase.
  3. Select
    Inhibit Equipment Phase
     to prevent the controller from executing this equipment phase.
    When selected, the equipment phase is still pre-scanned. If the equipment phase is then enabled when the controller is already in Run mode, the equipment phase is not pre-scanned again.
  4. Select
    Synchronize Redundancy Data after Execution
     to synchronize data at the end of the phase execution.
    This option is not shown for non-Redundancy catalog numbers. It is always enabled for controllers with Redundancy enabled as long as the controller is not in Hard Run mode. It is disabled when Redundancy is not enabled.
  5. From the
    Initial State
     menu, choose the state to which the system should initialize the equipment phase. Choose from:.
    • Aborted
    • Complete
    • Idle
    • Stopped
  6. Select
    Complete State Immediately if not Implemented or Empty
     to signal the completion of a state any time the equipment phase transitions to a state where the state routine is not implemented.
  7. In
    Initial Step Index
    , enter an initial value for the step index.
    Choose a number from 0 through 65,535.
  8. From the
    External Sequencer Loss of Communication Command
     menu, choose the action to take if communication with an external sequencer fails.
    In the event of a communication failure with an external sequencer that is currently an owner of the equipment phase, this selected command is invoked on the equipment phase. Choose from:
    • <none>
    • Abort
    • Hold
    • Stop
  9. From the
    External Request Hold Action
     menu, choose the action to take when an external request (that is, requests initiated using the PXRQ instruction) is in progress and the equipment phase receives a Hold command (while in the Running state). Choosing the
    Clear
     option aborts all external requests that are in progress. Choose from:.
    • <none>
    • Clear
  10. Select the
    Value assignment in an equipment sequence
     check box to assign values for phase inputs and output in an Equipment Sequence based on the value of step input and outputs. When selected, all phase inputs use the value of the related step input.
  11. Under
    Automatically assign the value of phase outputs to step outputs when the phase is
    , select a phase in which the
    Equipment Sequence
     uses the value of the related step output to evaluate the phase:
    • COMPLETE
    • STOPPED
    • ABORTED
  12. Select
    OK
     to save changes and close the
    Equipment Phase Properties
     dialog.
