About this task

For information on the specific Sideloop Output Control modules, see Sideloop in the Output Control Modules section.

Note: To manually create a Sideloop by adding the desired sideloop modules to the system, see the Adding an Output Control Module section. If you are not using the System Selection Wizard to create the sideloop, skip to Step 5.

To create a sideloop:

Procedure

  1. Click the Sideloop button. The System Selection Wizard appears with the Sideloop Selection screen active.
    Note: The Previous and Next buttons are disabled.
  2. Select the sideloop options for your system and click Finish. See the System Selection Tree section for information on tree behavior and use (for example, using the check boxes, radio buttons, and the + and - next to a node in the tree to show and hide selections). For information on the selection options in the Sideloop Selection screen, see the Sideloop Applications section. The Sideloop dialog box prompts you to name the sideloop.
    Note: As you make selections in the System Selection Wizard, you can press F1 to view the Help screen. The Help screen displays the module Help section of the item you are viewing and changes as you select different items in the wizard. Click the links on the Help screen to view module information.
  3. Click Finish. The Sideloop dialog box appears.
  4. Type a name to identify the sideloop being created.
  5. Click OK. The sideloop modules are added to the system with the name entered in Step 3 as their prefix.
  6. View and modify the sideloop modules’ details according to the steps in the Viewing and Modifying Details section. Make sure you note the enumeration set selected for the mode input of this module.
    Note: Make sure you set the Process ID and Process Units attributes according to the needs of your system. If the Process ID selected is Airflow, Airflow Diff, or Other, you must set the Process Range as necessary. The Process Range must be greater than zero. If the Process ID is Other, you should configure the Time Constant and Process Dead Time attributes from the details view of the PID Pre-Processor logic block inside the module’s logic view. See the PID Pre-Processor description in the Control topic of the Logic section for details.
  7. If necessary, expose and make connections between the modules according to the instructions in the Viewing and Modifying Connections section.
  8. View the Sideloop module column in the State Tables and modify the states as necessary. Keep in mind the enumeration set selected for the mode input of this module in Step 5. See the Viewing and Modifying State Selection Tables section.
    Note: If you did use the System Selection Wizard to add a column to the State Selection tables, then you must fully configure at least one of the tables in that column (for example, select a mode for each row in one of the tables). If you did not use the System Selection Wizard to create the sideloop, you must add the sideloop Output Control module as a column in the State Tables and modify the states as necessary. See the Customizing State Selection Tables section.
  9. View and modify the connections between the State Selection Table and the State Generators and Sideloop Output Controllers as necessary. See the Viewing and Modifying Connections section.
    Tips:
    • You can run the Sideloop System Selection Wizard as many times as desired.
    • Once a sideloop is created, you cannot re-run the sideloop selection process on one of the sideloops.
    • If you re-run System Selection for the main application after sideloops have been created, the sideloops are deleted.
