This feature allows you to apply a typical cable block diagram to plant loads. You can apply a selected typical CBD to a single load or to several loads that you select in the Electrical Index. As a result of this operation, the software will do the following for each plant load based on the reference items that are contained in the selected typical CBD:

  • Create all the plant equipment based on the reference items contained in the typical CBD.

  • Make all the associations among the new plant equipment as defined in the typical CBD.

  • Create a plant cable block diagram in which the selected plant load serves as a focal item. The name of the new CBD will be the same as the name of the plant load to which you apply the selected typical CBD.

  1. In the Electrical Index, expand the folder hierarchy Electrical Equipment > Loads by selecting the + icons or by double-clicking the folders.

  2. Expand the Motors, Static Electrical Equipment, or Other Electrical Equipment folder.

  3. Select one or more loads. To select several loads, select the folder, and then in the list view pane, hold CTRL while you select more than one item.

  4. Select Tools > Apply Options.

  5. On the Apply Options dialog, select the Typical CBD tab.

  6. Select Enable typical CBD.

  7. Beside the Typical cable block diagram box, select Find.

  8. On the Find dialog, select Find Now to display the available typical cable block diagrams.

  9. From the list of the available typical cable block diagrams, select an appropriate typical cable block diagram that you want to apply to the electrical loads that you selected in the Electrical Index.

  10. Select OK to return to the Typical CBD tab of the Apply Options dialog.

  11. Select the Populate empty item properties check box to update only those item properties that contain null data. When you select this option, the software does not overwrite the data that is not null. Clear the check box to leave existing values of the item properties as they are, regardless of whether they contain null or not null values.

  12. Select OK.

  • The software does not apply a typical CBD to plant loads in the following cases and logs the rejection reason in the Apply Typical CBD log file:

    • If the typical CBD does not contain any typical item that belongs to the same item type as the electrical item to which you are applying the typical CBD.

    • If the typical CBD contains more than one typical item that belongs to the same item type as the electrical item to which you are applying the typical CBD.

    • If the electrical item is not associated with a bus but the selected typical CBD contains a reference bus circuit.

    • If the selected electrical item is already associated with other plant items.

  • When applying a typical CBD to motors with space heaters:

    • The software deletes the space heater from the plant and applies the typical CBD to the motor.

    • If the typical CBD contains a reference motor with a space heater, the software creates a new plant space heater under the plant motor after applying the typical CBD.

    • If the plant space heater is associated with other items (for example, cables, control stations, signals, terminal strips, and so on), the software does not apply the selected typical CBD to the motor of the space heater and logs the rejection reason in the Apply Typical CBD log file.

  • When applying a typical CBD to loads that are associated with buses:

    • After applying a typical CBD, the software validates that the association has been retained.

    • If the association has been broken, the software searches for the root item in the electrical branch where the load is connected. If the root item is not a circuit, the software attempts to associate the root item with the bus in that electrical branch.

  • If the association of the root item with a bus is not possible, the software does not stop or cancel the process of applying the selected typical CBD.
