Hello I have a problem
I have two robot controllers C42F-A003 and for any reason they start to fail when i try to make a backup or try to load a program.
I try it in a lot of forms, only the programs i need, etc... the following error message appears CANNOT OPEN THE FILE.
I make the communication with a 232RS cable and with the 232KCWIN i can make the communication and i can edit the code use all the command monitor.
Someone know what could be the problem?
