You can also memorize four simple rules for starting LOGO! : 
1.  If neither LOGO! nor the inserted card contains a circuit program, the LOGO! Basic 

displays the following: 

3UHVV(6&

1R3URJUDP

 

2.  A circuit program on the card is automatically copied to LOGO!. The circuit program in 

LOGO! is overwritten. 

3.  If there is a circuit program in LOGO! or on the card, LOGO! adopts the operational state 

it had prior to POWER-OFF. Versions without a display unit (LOGO!...o) automatically 

change from STOP to RUN (LED changes from red to green). 

4.  If you have enabled retentivity for at least one function, or a function is permanently 

retentive, the current values are retained at POWER-OFF. 

 

 

Note 
When a power failure occurs while you are entering a circuit program, the program in LOGO! 

is deleted after power is returned. 
Before you modify the circuit program, save a backup copy of your original to a card or to a 

computer, using LOGO!Soft Comfort.
