Switching with the cursor buttons
With EZ, 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 P1 to
P4. The P buttons can be activated and deactivated in the
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.

and I2 or using cursor buttons
Í Ú.
Example 2
Terminal I1 is used to control output relay Q1. Terminal I5

used in the circuit diagram.
