Switching Via the Cursor Buttons
With Pico GFX-70, you can also use the four cursor buttons as hard-wired
inputs in the circuit diagram.
The buttons are wired in the circuit diagram as contacts
P 01
to
P 04
. The P
buttons can be activated and deactivated in the h System menu.
The P buttons can also be used for testing circuits or manual operation. These
button functions are also useful for servicing and commissioning purposes.
