Note 
You can invert individual inputs of the basic and special functions; that is, if an input 

carries a logical "1" signal, the circuit program will output a logical "0". On the other hand, 

a logical "0" is inverted into a logical "1" signal. 

To invert an input, move the cursor to the relevant position, e.g.: 

[

Confirm with OK. 
Now press   or   to invert this input:   
Next, press ESC.

You can review your first circuit program by pressing   or   to move the cursor through the 

circuit program. 
We shall now exit circuit programming mode. To return to the programming menu: Press 

ESC 

 

 

Note 
LOGO! has now saved your circuit program to nonvolatile memory. The circuit program 

remains in the LOGO! memory until you explicitly delete it. 
You can save the actual values of special functions in the case of a power outage assuming 

that these functions support the "Retentive" parameter and that the necessary program 

memory is available. The Retentive parameter is deactivated when you insert a function; to 

use it, you must enable this option.
