Duplicating/Editing a Program
Here's a simple way to duplicate a program in memory so that you can save the original program and modify a duplicate program for a new part.
Simply press List Program, cursor to Device and select Memory.
Then cursor to the right and select the program to be copied, and then press enter.
Now, key in the letter O followed by a new program number, and then press the F2 key to duplicate the program.
The duplicate program will be listed in the directory with the new number. (On older controls, there's a similar method using the F1 key.)
