Equipment Sequence Properties dialog box - Configuration tab

Use the
Configuration
tab of the
Equipment Sequence Properties
 dialog box to create or modify the execution of the Equipment Sequence. The following options are available on the
Configuration
tab.
TIP: To open the Equipment Sequence Properties dialog box - Configuration tab, right-click an Equipment Sequence in the
Controller Organizer
or
Logical Organizer
, select
Properties
, then the
Configuration
tab.
  • Use the
    Inhibit equipment sequence
    check box to prevent the controller from executing this equipment sequence.
  • Use the
    Retain sequence ID when resetting sequence
     check box to retain the sequence ID when resetting the
    Equipment Sequence
    . If this is not checked, a RESET command will clear the Sequence ID value of an
    Equipment Sequence
    .
  • Use the
    Generate sequence events
     check box to record operator commands.
    Important:
    The
    Generate sequence events
    check box is only available on
    ControlLogix
     5570 controllers,
    CompactLogix
     5370 L3 controllers,
    ControlLogix
     5580 P-controllers, and
    Studio 5000 Logix Emulate
     controllers. The check box is grayed out and disabled on all other controller types.
  • Use the
    Unit ID
    field to assign an integer value to represent the piece of equipment unit a sequence is coordinating.
    • A Sequence Chart has two Unit ID properties:
      • Configured Unit ID
        • The Configured Unit ID is set in the Logix Designer application in the
          Equipment Sequence Properties Configuration
          tab.
        • When a Sequence is created, the Configured Unit ID is set to 0.
        • When the Configured Unit ID is changed, the Unit ID is set with the new Configured Unit ID if these conditions are true:
          • The Sequence state is Idle.
          • No external attachment is present.
          • No internal attachment is present.
          • No Start command is present.
      • Unit ID
        • The Unit ID is:
          • Included in the Sequence backing tag.
          • Set to the Configured Unit ID when the Sequence state returns to Idle.
          • Set to the Configured Unit ID when the controller is powered on or power cycled.
          • Set to the Configured Unit ID when the controller changes from Program to Run mode if no external sequencer is attached to the Sequence.
          • Set to the Configured ID after a switchover if these conditions are true:
            • Its Sequence state is Idle.
            • No Internal owner is attached.
            • No Start command is present.
          • Included in the Event Log when a Sequence starts.
          • Set by an External Sequencer when the External Sequencer attaches to the sequence if the Sequence state is Idle.
          • Set to the Configured Unit ID when an External Sequencer detaches from the Sequence if these conditions are true:
            • The Sequence state is Idle.
            • No Start command is present.
          • Set to the Configured Unit ID when an External Sequencer connection is lost if these conditions are true:
            • The Sequence state is Idle.
            • No Start command is present.
          • Set to the value in the Unit ID parameter of the SATT (Sequence Attach) instruction when an Internal Sequencer attaches to a Sequence with the SATT instruction.
          • Set back to the Configured Unit ID when an Internal Sequencer detaches from a Sequence with the SDET (Sequence Detach) instruction.
  • Use the
    When starting sequence
    option to:
    • Use the initial value of a tag when starting an Equipment Sequence.
    • Use the current value of a tag when starting an Equipment Sequence.
  • Use the
    When resetting sequence
     option to:
    • Restore the tag to its initial value when resetting an Equipment Sequence.
    • Maintain the current value of a tag when resetting an Equipment Sequence.
