Equipment Phase Properties - Configuration tab fields

Configuration
tab of the Equipment Phase
PropertiesEquipment Phase
. These options are available in the Configuration
tab. 
Name | Purpose | |
 | Prestate | Defines the prestate routine executed prior to the execution of any of the other state routines. Prestate routines are optional routines to perform some failure detection, verify that all control modules are in the correct state, or execute other logic common to all 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. |
 | Fault | Defines the fault routine executed by the equipment phase whenever a major fault occurs within the equipment phase. |
 | Inhibit equipment phase | Prevents the controller from executing this Equipment Phase . Clear the check box and the controller executes the Equipment Phase . The check box is clear by default. |
 | Synchronize redundancy data after execution | Synchronizes data with the controller at the end of the phase execution. The check box is not shown for controllers that do not support redundancy. The check box is always enabled for controllers with redundancy enabled as long as the controller is not in Hard Run mode. The check box is disabled when redundancy is not enabled. |
 | Initial state | The initial state can be:
Tip: Equipment Phase s must be configured to have an Initial state of IDLE to work with Equipment Sequence s. |
 | Complete state immediately if not implemented or empty | Use this check box to signal the completion of a state any time the equipment phase transitions to a state where the state routine is not implemented. |
 | Initial step index | Defines the initial value for the step index. |
 | External sequencer loss of communication command | Defines the command to invoke if communication with an external sequencer that is currently an owner of the equipment phase fails.
|
 | External request hold action | Defines the action to take when an external request initiated using the Equipment Phase External Request (PXRQ) instruction is in progress and the equipment phase receives a HOLD command while in the RUNNING state. Choose from:
|
 | Value assignment in an equipment sequence | Use 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. |
 | Automatically assign the value of phase outputs to step outputs when the phase is: | 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:
