Masking Super Blocks

Apply a mask to hide the underlying blocks of a super block.

Masking is the main action from the Mask tool group. Masking hides the interior blocks of a super block and changes the super block to appear and act like a regular block. Additional tools let you edit, remove and restore a mask.
  1. From a diagram, select a super block:
  2. On the ribbon, from the Mask tool group , click the Auto Mask tool: .
    The super block is masked and behaves like a regular block. For example, double-clicking a block or a masked super block opens a block dialog for modifying parameters, whereas double-clicking an unmasked super block opens the diagram associated with the super block.
  3. Double-click the masked super block.
    For the masked super block named, Controller, which contains a diagram of a PID controller, the following block dialog appears with the parameters I, D and P:
    The values for these parameters are the input entries, I, D, and P, which are the context variables defined in the context of the root diagram of the Controller super block.
