Do any PLCs give the programmer a way to tell if a program has been edited and/or reloaded? For example, if you supply a program to a customer, and after startup and debugging a plant "technician" one day edits the program, something goes awry, and the original copy is downloaded back to the processor to cover his error, is there a way to discover this? Hasn't happened yet, but it is something I've thought about.
