Wiring Block Diagram Objects Manually

You transfer data between block diagram objects through wires. Use the Wiring tool to connect the terminals on a VI or function to the terminals on another VI or function. Use automatic wiring to wire objects as you place them on the block diagram.

Complete the following steps to practice wiring on the block diagram.

  1. Place two VIs or functions on the block diagram.
  2. Use the Wiring tool to move the cursor over a terminal of a VI or function. When you move the Wiring tool over the terminal, the terminal blinks, and a tip strip appears.
  3. Use the Wiring tool to click the terminal and release the mouse. LabVIEW draws a wire between the terminal and the Wiring tool as you move the cursor across the block diagram, as though the wire were unwinding from a spool.
  4. Without holding down the mouse button, move the cursor to a terminal on the second VI or function. The second terminal blinks, and a tip strip appears.
  5. Use the Wiring tool to click the second terminal.

To wire from or to an existing wire, complete the previous steps, starting or ending the operation on the existing wire. The wire blinks when the Wiring tool is correctly positioned to fasten a new wire to the existing wire. To wire from an existing branch when automatic tool selection is enabled, move the cursor over a wire and press the <Ctrl> key to temporarily switch to the Wiring tool.

Macintosh Press the <Option> key. Sun Press the <Meta> key. Linux Press the <Alt> key.

You also can right-click the existing wire and select Create Wire Branch from the shortcut menu.

You can wire structures, select wires, delete wires, and move wires.
