I'm facing a problem with GE Fanuc VersaMax PLC connected with Cimplicity SCADA. The program in the PLC is getting erased automatically when the PC (where SCADA is installed and connected with PLC through Serial port) is restarting. What could be the reason?? Please help me to sort out this issue.

Thanks.

 

The data you had posted is not so clear. I want to know whether the PLC is also getting rebooted frequently along with your PC. Secondly, check your PLC CPU Battery voltage. Is there any abnormality in LEDs glowing on the CPU of PLC?

 

Check the PLC Memory Battery.
