Access management in the client

The system provides functions for managing access in the client. The functions can be used to log out a user and to check the user's current access. The functions are available in the development environment in the Actions and Conditions Editor.

Check Access

Function for querying whether a certain control access method is permitted for the logged-in user or not.

GoToLoginPage

Function to open the login page without logging out the currently logged in user. This allows a user change to be performed without a previous logout of the user.

Logout

Function for logging out the logged in user from the TwinCAT HMI server. The function loads the login page after the logout.
