I have a question

I new using PLC mitsubishi, we like to modify a program but when execute a "can not write ROM" apper, the PLC type is A1SJCPU, how can I modify the program?
Do I need a rom writer to can do it?

When you remove the ROM you should see some dip switches. They need to be in a certain position for you to write.

Go to the Mitsu Web site for manuals...
