On start up CitectSCADA will establish initial communication with the server using a view-only login. By default this communication between the client and the server is in view-only mode. In this mode the user cannot write to any tag, acknowledge any alarm or use Cicode functions.
Note: View-only mode is applied to the whole control client process, including any Cicode task that is running.
Write only access is available after a user has successfully logged in. Once the user logs out it returns to view-only mode.
Users can configure login by modifying the [Client]AutoLoginMode parameter.
