Configuration Tasks

  1. Add Equipment Using Equipment Editor: Create the equipment for the required objects. Organize the equipment in a hierarchy. Objects can be referred to by their name when you add Composite Genies to a graphics page. You can add one or more instances of an equipment to a page.

  2. Equipment References: Create the required relationships (equipment references) between a piece of equipment to items of another piece of equipment. This allows you to refer to equipment.items outside of the equipment hierarchy.

  3. Configure PLC Limits with Equipment: This is an optional task that is required if you want to use PLC alarm limits instead of the standard analog alarm limits.

  4. Insert a Composite Genie: Create graphics pages with instances of Composite Genies that are associated with the equipment you have defined in your project.

  5. Create a New Faceplate: Add a faceplate for the equipment to allow operators to engage with the equipment at runtime.

  6. Write Cicode functions to initialize PR and OR values. Refer to the Cicode Reference documentation for more information.
