Avoid program copying

But if I load the program from computer to plc through cable ethernet and subsequently I insert the SD card in the LOGO!, the program is copied without the password request, then moving the sd to another device the program is copied. Furthermore, the password is requested when I try to modify the parameters while the program is not running, and this is not good because in this way I create unsetable parameters. can I prevent the program being copied from the plc to the sd card without the request of the entered password?

The program can then be saved, as you have written, on the SD card without problems. After that I have via Software deleted in the LOGO! the program and the Password. The LOGO! could not then start, the display indicated "empty program". Only after switching the voltage off and on again, the LOGO! loaded the program from the SD Card and let itself start again. And the program protection via password was active again.
