FX-EEPROM-8 CLEAR

[star_69 4]

Hi to everyone, I have a FX2N series PLC with an FX-EEPROM-8 memory and a E200 HMI. There was a problem when you try to inputs some variables from the HMI, and i ask from the company that produses this machine, to send me the program of the PLC and HMI, , They send it to me (the software to open it is Meldoc) and i write the program to the PLC but now there are More Viriables i just can't write, when i try to write these viriables the HMI goes to the next viriable for input. i try to rewrite the program and there was no lack, i was wondering if something is wrong with the eeprom, because i haven't write EEPROM before. any one has an idea? thanks in advance.

Just as a test, have you tried removing the EEPROM and download the project? If you remove the EEPROM and download the project, you will download directly to the program memory in the PLC. That way we can probably sort out if you've gotten the wrong program, or if the EEPROM is defect.

No problem, but you never said if the EEPROM actually was defect? Was it?
