 |
|
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 autentic program. There is no password for write protection.
Anybody had the same problem?? Please help me! |

You have to compus RAM and ROM but the ROM can be altered only if you detached the backup baterry from CPU and
do boot from standard ROM.
However if you read carefully you know how to proceed. |
