Downloading Program Off of FX3U PLC Always Incomplete

7 posts in this topic

Hello everyone, I have a question regarding a problem I have when downloading saved program on PLC to my PC. So whenever I try to download the program that's already saved on the PLC for backup purposes, the program is always incomplete, by this I mean the program would have missing parameters which causes PLC not to work properly. I am new to this and would like some advice on how to fix this. I would like to know what might be causing this problem. Additionally, is there a compatible version of the software to use on Windows 7? For reference: PLC is FX3U-16MT Software used is GX Works 2 [1.24A-H03] and GX Developer [8.70Y] Operating System is Windows XP 32-Bit Thank you so much for your help.

What do you mean with "Backup purposes"? Do you have an additional memory card installed in the PLC, or just the regular program memory? Which software did you use to download the project (download = PC->PLC)? Which software are you using to upload the project (upload = PLC->PC)? Your GX Works2 is pretty out of date, do you have an updated version of the software? GX Works2 is supported on Win7 x32/x64. GX Developer is not officially supported on Win7, but works fine for most people

Hi Ulik, Dit you try to verify first to see if there are differences in the program on your PC and the program inside the PLC? This should not give a list of errors. Afterwards you can back-up if you like however is there is a 100% match this is not needed to save again. If there is no 100% match and you make an upload to the PC all the new items are at least without labels (if you use a simple ladder program) If you have legal software you can register this at the mitsibishi portal and get updates for free for your GXWorks2. Good luck, Theo V.
