Insert value in a I/O field by password

Hi everyone,

I'm a beginner with WinCC Explorer and I don't know if there is a function to use for my purpose. I would like to know how to insert a value in a I/O field only after I insert the right password. In a few words, I want to protect that field from unauthorized access so when you click on it, a pop up has to show, telling you to insert a password. If the password is right, the pop up has to close and the field become writable, otherwise the pop up tells to retry. How can I do?

Thanks for your help

Hi,

Have you considered this:

How do you run certain actions depending on the authorization level of the logged-on user?

I hope I could help!

You could make the I/O field Output only, then in Mouse Click event, make a Popup windows appear that asks for the password in a I/O Field then make something like this on the OK button of the Popup Window:

dim field
set field = ScreenItems("Password Protected Field")

if ScreenItems("Pass I/0 field").OutputValue = "your pass" then

field.BoxType = 1  ' Changes Field Type to 1 so user can input Data

else

 'Manage incorrect Pass

End if
