Hi, thank for the answer. That give me an idea for getting similare result.
The step i use:
In rapid module with NoView.
I use trap and IPers for confirming and managing the acces of many user.
I have created a record for holding each user / password and a function for comparing it in an array.
When a password is enter, this trigger the iPers and the trap compare each user then set an io for the HMI to use if a match is fund.
Finally, i use a conditional trigger to root me in my page in the screen manager.
The main drawback is the user and password is hard code in a .mod file.
