Switching via the cursor buttons
With easy800, 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
P01 to P04. 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.
