I am attaching more information about it. Additionally, if you encounter any errors, please upload them as they will surely be helpful for people browsing the forum. - Why can you not download any programs into your new LOGO! 8? I hope this information is helpful.

Gamma-italia Posts: 2 Rating: (0)	So I can connect via ethernet with the logo, I can upload the logo to the PC, but I can't download it from the PC to the logo. The format of the file in the program created in Logo 8.3 is .lld, however the Logo 8.4 software writes and reads it in .lsc That's why I'm asking if there is any way to convert the .lld file to .lsc, so in theory the problem would be solved. I tested making a program in .lsc and I can download it normally. Either there is some kind of converter or I must copy the entire program manually. I don't see any other option. Thanks!

You can update/upgrade any older version of LSC to the current version V8.4.1 for free. The update/upgrade can you download from here: Firmware update for LOGO! 8.4 basic devices and service pack 1 for LOGO! Soft Comfort V8.4 If you have install the update/upgrade then load your program and select in the hardware selection the right LOGO! type LOGO! 8.4.

Why don't you write this not in the opening post? There ist a button in the diagram menu to convert a LAD diagram to a FBD diagram an otherwise.

Update the PLC firmware to 8.4 if possible or open the 8.3 project in the 8.4 software, re-save it, and try downloading it again. On a lighter note, while troubleshooting, consider relaxing with the DixMax APK, an app for streaming movies and TV shows, which could be a nice break from technical tasks!
