LOGO! Manual
A5E00067781 01
Try to remember the 4 simple rules for starting LOGO!:
1. If there is no program in LOGO! or on the connected
program module, LOGO! (with display) displays the
message: No Program.
2. If there is a program on the program module, it is auto-
matically copied to LOGO!. If there is already a program
in LOGO!, it is overwritten
3. If there is a program in LOGO! or on the program mod-
ule, LOGO! adopts the operating status it had before
power off. If you are using a variant without display
(LOGO! ...RCo), it automatically changes from STOP to
RUN (the LED changes from red to green).
4. If you have switched on retentivity for at least one func-
tion or are using a function with retentivity permanently
switched on, its current values are retained at power off.
Note
If a power failure occurs while you are entering a program,
you will find when the power is restored that LOGO! no
longer contains the program.
You should therefore save your original program before
changing it on a program module (card) or on a computer
(LOGO!Soft Comfort).
