QX611-1 Mitsubishi PLC failure

Hello everybody, I have a problem with a Mitsubishi PLC, the CPU is QX611-1 and it is installed in a CNC machine, someone has removed the backup battery and after that the systems is freezes and can't be accessed anymore, the machine is a peace of junk right now, please help me to fix this problem.

I have found the GX Developer software and MEDOC to reprogram the PLC but the problem is I don't know it they are the required software to do the job, also I don't know what cable to use. I really appreciate your help.

Thanks.

This Cable and GX Developer should do the trick.

There is no round 7 pin female port on the controller anywhere? the 9pin female RS232 on the cable connects to the serial port on your laptop.

No, unfortunately it is not there also in the DX Developer I can't see the QX611-1 CPU that is confusing.
