I have a problem and cannot find a good solution for a list of part #'s on a HMI. I have around 30 int #'s thats just say 0-29 from a symbolic field that the operator can change to various different products. if the operator changes the list to something else say was on 0 and change it to 20 I wish to know it has been changed to trigger the machine change.
What is the best way to see if the list has been changed.
Thanks for any help
