This simulates the closing of the external input circuit. However, the
actual open/closed status of the external input circuit no longer affects the
program logic.

• The instruction state box is filled, indicating that I/6 is true.
• FOn appears in the upper right-hand corner, indicating that the input is

• The controller’s Forced I/O LED is on continuously.
