The first step for providing a user management for the Operator interfaces is the creation of a page for the user login. At its plainest, this page has two input fields for the name of the user and the password, plus a button to execute the login. The example of a User management we used has an input screen created for optical reasons.
We wanted to create a multi-lingual log-in. As a first step, we created the required languages under " System > Languages " in the Object Explorer. Sprachen angelegt. For the titles of the dialogue, the fields and the button we used a text list each instead of a text object, since a text list provides the option of defining a text for each language for a text input, and this can then be selected via a global variable.
Proceed as follows:
•Create the text lists for the individual objects with the required languages. In our example these would be for the title of the dialogue, the input fields and the log-in button.
•Position them at the appropriate place in the input screen.
•Create an input field for the user name and, in the "Variable" group field, allocate to it the variable whioch you have defined in the "Base" register of the user management in the "User name:" parameter.
•Create an input field for the password and allocate to it the variable which you have defined in the "Base" register of the user management in the "Password" parameter.
•Create a touch field for calling up the log-in.
•In the "Graphics list" register, allocate the required graphics to this touch field. 1. graphic for the normal state, 2. graphic for the pressed state.
•In the touch field dialogue, change to the "Functions" register. Set the "Login" function.
•If you want the Login to immediately call up a page, also set the "Page selection" function.
•Save this page.
