6.2 Configuring Displays
A display can consist of static and dynamic parts. The controller does not update static parts, such
as texts and graphics.
Dynamic parts are connected to the controller, and visualize current values from the controller’s
memory. Visualization can be in the form of alpha-numerical displays, curves, and bars. Dynamic
parts also consist of inputs made at the OP that are written to the controller’s memory. They are
interfaced with the controller by means of Variables.
For our color mixing plant, five displays are to be generated initially.
Display Template
This display is set up automatically, and contains central functions.
In the upper area of the display, a permanent window is generated. Here, the levels of the tanks, of
the container and the project name are shown.
In the lower area of the display, the message window and the message indicator are shown. These
objects are also embedded in all displays, and are opened in the display’s foreground if there is a
message, for example.
Basic Display
This display also is set up automatically, and it is also defined as start picture. Here, the entire plant
is shown
Changing the operating mode, starting the mixing process, operating the mixer motor manually, and
opening the outflow valve can be performed by means of buttons. The motion of the mixer and the
states of the valves are shown graphically. By means of input fields, the amounts of the individual
additives are specified. In addition, it is to be possible to jump to the other displays. Using the button
END, the runtime at the panel is terminated, and a new transfer can be made.
Tank1
In the third picture, the valves of Tank1 can be operated manually. The maximum and minimum
amount of filling has to be preset at linear regulators. By means of buttons (Open valve), the inflow
and outflow valve can be opened or closed. The valves are shown graphically, and change color
when they are open.
The level is indicated in red. If the maximum level is reached, the inflow valve is closed in the
automatic mode. When the tank is completely full, the inflow valve can not be opened.
With additional buttons, you can switch to the other tanks, or to the basic display.
Tank2, Tank3
The displays for Tank2 and Tank3 are structured exactly like the display for Tank1.
The valves and the level of Tank2 are colored green.
The valves and the level of Tank3 are colored blue.
