I am having many machines (similar but not the same) running a piece of program, which keeping evolving in the last 10 years.
Sometimes, the site engineers would like to have the newly developed functions on the old machines. So I clone the necessary bits and merge to the old program.
I am using the Block ID number for tracking the change point. Unfortunately, the Block ID is self-generated by the editing software. I would like to know if there is a way I can define/change Block ID, so I can maintain all versions program with the same Block ID.
If not, anyone can share an idea how to maintain the program in a tidy manner? Thank you very much!
P.S. My background is PLC programmer, Opto22 is new for me.
