Info

The comparative value is determined according to the setting in the 'Password level' field. This must be set in the editor during the creation phase. 4.7.4.2 Entering Passwords Visual Components provides two methods for entering passwords. The first method allows password operation to be configured in Visual Components during the creation phase. The second possibility entails evaluating the actual input using the controller application. Both fields are inserted in the Visual Components picture editor. After selecting the icon (shown here to the left) from the toolbar, this menu appears. Evaluating passwords can be applied by selecting Input String. A variable is connected which writes the password to a string variable or byte array using echo characters (i.e. *****). The input string is evaluated in the application program. Password logic is managed in Visual Components with the Input Password option. In contrast to string input, however, this method is limited to the number of password levels. After inserting the desired input field, the 'Properties' dialog box appears to edit it. 'Properties' can also be opened by double−clicking on an existing input field. 4.7.4.2.1 Formatting the Input Password input essentially supports the same positioning, formatting, and colors as string input fields (see also Text Input). The maximum length of a password field is 6 characters. This is also the maximum length for adjustable passwords. Additionally, the Echo character field determines which characters should be used to display on the screen in place of the entered password characters (for security reasons, actual character input is not directly visible). 4.7.4.2.2 Connecting Variables Introduction to Visual Components 2.3 A numeric variable has to be connected in the 'Destination (Password) Data Point' field. The input field recognizes the possible passwords and converts them to the appropriate authorization level. The variables connected here can be used directly as password variables for input fields, as described above. For this, the Password value >= Level mode is used and the desired password level entered. 354 4.7.4.2 Entering Passwords
Introduction to Visual Components 2.3 A status variable or completion data point can also be defined if necessary. 4.7.4.2.3 Defining Passwords Passwords for this field are determined during the creation phase and can no longer be changed while the program is running. If changing passwords during runtime is necessary, string input in Password mode and controller application logic need to be used. Up to 4 password levels can be defined which are numbered from 0 to 3. The number of the corresponding password level is transferred to the password variable. If a valid password is not entered, then 0 is written to this variable. This level must therefore be used for inputs which are always available. Password levels 1 to 3 can be set under the Passwords tab. The number of password levels can be set under Number of Password Levels. 2 to 4 levels are possible. The first level (level 0) is used if an incorrect password was entered. Corresponding passwords are entered in the input fields Password #1 to Password #3. The password variable is set to the appropriate value (the number before the # character) after a password is successfully entered. If an incorrect password is entered, then the password variable receives the value 0. 4.7.5 Using Input Fields on Touch Screens Guiding users through the input of numeric and alphanumeric characters is different on display units with touch screens than it is on displays with keys. Visual Components provides the possibility to display a virtual keypad on these touch displays. It opens automatically when an input field is touched and allows characters to be input to the field which is to be edited. Support is limited to graphic touch displays (display units for the IPC2001 and IPC5000 series). Matrix touch displays, which can be operated with the C130 CAN controller, are not supported in this way. Operations are carried out as with normal keys. 4.7.5.1 Using Touch Keypads 4.7.4.2 Entering Passwords 355
