I have a Q00 PLC from a customer who want to modify some in Main program. First I upload program from PLC using GXWork 2. Everything is ok. But when I download the editted program to PLC, it doesn't save the editted program. After powering off the PLC, I upload it again and find out it still saves the original program. There is no password for write protection.
Anybody had the same problem?? Please help me!
