Parameters

Connection — Connect to signal

signal name

Connect to signal for display, selected from list of signal names.

To view the data from a signal, select a signal in the model. The signal appears in the Connection table. Select the option button next to the signal you want to display. Click Apply to connect the signal.

The table has a row for the signal connected to the block. If there are no signals selected in the model, or the block is not connected to any signals, the table is empty.

Label — Block label location

Top (default) | Bottom | Hide

Block label, displayed at the top or bottom of the block, or hidden.

• Top

  Show label at the top of the block.

• Bottom

  Show label at the bottom of the block.

• Hide

  Do not show the label or instructional text when the block is not connected.

Programmatic Use
