VersaPro Online Edit

Hi

Is it possible to do an online edit of 1 rung?  I can only see that I could do do a change then download the whole program.

Thanks In advance

When you do an online edit in GE, VersaPro writes the edited program block to available memory in the PLC. When that is done, it resets a pointer that defines the start of the program. That's how it allows you to send an edited program without having to stop the PLC. As BobLFoot suggests, not all CPUP models support the technique.

If you don't break up your program into subroutine blocks, and the program uses more than half of the memory, then you have to stop the PLC to download modifications.
