Functionality

Display variant depending on the target platform

You can run the same visualization on different target platforms. Possible display variants include CODESYS WebVisu, CODESYS TargetVisu, and CODESYS HMI. In the development system itself, there is an "integrated display".
Visualization editor

In the graphic editor, you design your user interface from visualization elements. The visualization elements are provided from libraries in the Visualization ToolBox view. You drag an element to the editor area and adapt it in its Properties view.
Referenceable visualizations

A visualization can be referenced in other visualizations. This allows for the creation of user interfaces with a complex structure. To do this, CODESYS Visualization also provides predefined visualizations, for example for dialogs.
Simple design change

A simple change in the look and feel of a visualization is possible in one location by creating another visualization style.
Multi-language capability

You can use text lists to conveniently provide visualization texts in multiple languages. You can configure a user input element for switching to another language in online mode.
User Management

You can set up a visualization-specific user management for access control up to the level of the single element.
Other useful features

Function block instances of visualizations, array access from the visualization, real-time data logging, extendability of the pool of visualization elements, provision of graphical objects from symbol libraries, calls of PLC functions from the visualization, reusability of visualizations by depositing them in libraries.

Overview of the objects in CODESYS Development System which are relevant for the visualization
Visualization	Object below an application in the device tree or in the POU pool with the programmable visualization screen A visualization can reference other visualizations so that multiple visualization screens become one user interface with any number of pages at runtime.
Visualization editor and additional views	In this IEC 61131-3-compliant editor, you use the visualization elements to create the desired graphical user interfaces, panels, dialogs, etc. The editor is made up of the following components: Graphical editor to arrange the elements Interface editor: To parameterize the visualization Keyboard Configuration: Configurator for keyboard inputs for online operation Element list: Overview of all used visualization elements and editor for the position of the elements on the Z-axis The following views are also available: View: Visualization ToolBox: Provides the available visualization elements View: Properties: Displays the element properties of the element currently selected in the editor
Visualization element	Finished element from one of the visualization libraries The elements from the libraries are provided for you in the View: Visualization ToolBox.
Visualization Profile	Defines which library is integrated with which version Each project that includes a visualization is based on this kind of profile in the project settings.
Visualization style	Determines the "look & feel" of the elements The style is set application-wide in the Visualization Manager. Ready-to-use styles are provided and you can also create your own.
Visualization Manager	Configures features such as user management, style, language, input type, etc. for all visualizations of the parent application. The Object: Visualization Manager object is located below the application in the device tree.
Display variant	A visualization can be displayed in online mode in the following variants, which are created as objects below the Visualization Manager: CODESYS TargetVisu Target visualization and remote target visualization (Remote TargetVisu) on PLC devices CODESYS WebVisu Web visualization via a web browser CODESYS HMI HMI visualization on devices without an I/O connection Visualization integrated in the development system
Visualization library	Collection of visualization elements that are provided in the View: Visualization ToolBox view
Symbol library	Collection of images and graphics that you can use in visualizations. When you insert a visualization object, you can choose which of the installed system libraries should be available in the project.
Visualization Element Repository	Repository to manage the visualization profiles and the visualization element libraries
Visualization Style Repository	Repository to manage visualization styles
`VISU_TASK`	Task which is automatically inserted as an object in the task configuration of an application Requirement: At least one object of a CODESYS WebVisu or CODESYS TargetVisu is configured below the Visualization Manager.
