i am writing a program in LD, we have 3 screens on the advanced RTD. the main screen which shows the company logo and 2 buttons. one button takes the customer to a level screen to show them the levels of a couple of chambers. the other button takes you to a set up screen where levels are set in the program to turn on or off various outputs for indication purposes. this screen we would like to password protect so only our engineers can change the parameters set. i have tried playing about with the program but dont seem to be able to do it, is it possible that when we press the set up button we are asked for a password to be allowed access the the set up screen.
