Hi I need help in online editing while PLC in in run mode. Currently, I need to stop the PLC then can write the program. Why is it writing to EEPROM? Thanks

I'm using GX Developer Version 8 I can do online monitor but i cant online write. I have to stop PLC then write to plc. Is it because I have EEPROM attach to the PLC?

Problem is that the program is stored in EEPROM which require to stop PLC in order to edit the program. I want to store the program in RAM so that I can online edit the program while the PLC is running. But when i create a new file, it only allow me to write to EEPROM, not RAM. With EEPROM attach to A1SH PLC, does it "bypass" the RAM & only EEPROM is accessible? Thanks

You will have to remove the EEPROM
