The Action Sequence Function Step type is used to define a point to which you want to issue a certain function. Configure an Action Sequence Function type step using the Action Sequence Designer.

The Action Sequence Function Step dialog appears as follows:

To configure an Action Sequence Function Step:

  1. Open the Action Sequence Designer for the Action Sequence of interest. For more information on how to open the Action Sequence Designer, see Open an Action Sequence in the Action Sequence Designer.

  2. Do one of the following:

    • Insert a new Action Sequence Function Step into the Action Sequence. For more information on how to insert an Action Sequence Step into an Action Sequence, see Insert new Action Sequence Steps.

    • Identify the existing Action Sequence Function Step to be modified.

  3. Optional: To skip this step when the Action Sequence is activated, select the Inhibit checkbox.

    Note: If the Inhibit checkbox is selected, the Controller will be unable to uninhibit this step in the easy eXtended Operator Station (ezXOS).

  4. In the Name field, type a name for the step record in the Sequence Step (sequenceStep) table.

    Note: This name is automatically generated. By default, the Name field in the step appends the Action Sequence (actionSequence) record name to it.

  5. In the Point field, click (...) to select the RealTime point path (table and record) on which the operation is to take place. For more information about how to select a pathway, refer to Volume 1 of the RealTime Administrator documentation. The path can belong to one of the following tables:

    • batchXfer

    • plm

    • plmvoldevice

  6. In the Command field, select the command associated with the selected Point field. This command is executed when the sequence step runs.

    Notes: This field only applies to batchXfer, plm, and plmvoldevice points.
    For a list of available functions, see List of available Action Sequence functions.

  7. Optional: Link the new Action Sequence step to subsequent steps to construct the Action Sequence. For more information on linking Action Sequence steps, see Link Action Sequence Steps.

    Note: You can link the Out ports of two or more Action Sequence steps to the In port of a single Action Sequence step. This allows you to merge Action Sequences steps. For more information, see Merge Action Sequence Steps.

  8. Select Save to save the changes to the Action Sequence.
