Key Concepts and Terms
Display / Screen
A display is
the visual interface in an application that allows users to adjust data. Its function is to present information clearly, using text, graphics, and interactive controls. The display operates via a rendering engine, responding to user inputs. These displays are used in data visualization, control systems, and user interfaces, enabling users to input information, receive feedback, and execute actions within the application.a window or frame of your application’s user interface. A display can contain multiple graphical elements. The elements of a display can be static, meaning they always appear the same, such as a title or an image, or dynamic, such as a gauge or a color status indicator.
In the context of this documentation, the terms display and screen can be used interchangeably when referring to a user interface window. When referring to the configuration objects or the module, the term "Display" is used.
Layout
Layouts allow the organization of the user interface into frames or panels, acting as containers for your Displays. For instance, a typical layout includes a top display that remains constant with navigation buttons, and an area below where different displays can be shown.
Client
A client is a software component that interacts with a server or services, including types such as .NET Clients, HTML5 Clients, and Remote Clients.
Its role is to enable user interaction with the application, involving handling user input, displaying information, and executing logic. Clients can perform tasks locally or communicate with a server to exchange data.

Rendering Engine
A rendering engine generates visual output from an application's
data and logic. Examples include WPF for Windows applications, HTML5 for web applications, and Portable for cross-platform compatibility. The rendering engine will transform abstract data and instructions into visual representations. These engines interpret code, process styles and layouts, and generate the visual output for displays. They are used in developing graphical user interfaces across various platforms and technologies, aiding in the creation of visually appealing and interactive user interfaces| bgColor | #ffffff |

display drawing. In our context, the Engine can be WPF, HTML5, or Portable meaning that the same displays can be rendered to WPF or HTML5 clients.
PanelType
Panels are containers for organizing the display’s graphical elements. The PanelType defines how those elements will be organized. Our platform supports Canvas and Dashboard as PanelTypes.
Our Platform support Canvas and Dashboard as PanelTypes.
Canvas (or Process Screens): The elements are in a drawing surface, where each element has its specific location and size.
Grid (or Dashboard Screens): The elements are placed in a grid with responsive size, columns and rows. The graphical elements adjust accordingly
Panel Types
Panel types, like Canvas and Dashboards, work as containers for organizing display elements. Their purpose is to structure and arrange content within an interface. These types define how elements are positioned and organized, affecting the display's layout and design. Used in designing display layouts, they help create organized interfaces, enhancing user experience and application usability.
→ Read more about Responsive Dashboards.
Understanding the Displays Module
The displays involve an interplay between technologies, operational processes, and visual configurations. Exploring display technologies and client types provides a foundation for tailoring displays. The operational aspect organizes elements for an enhanced user experience, including screens and dashboards. Additionally, understanding display modes and stretch options for shaping how information is visually presented on the screen helps ensure adaptability and responsiveness. These components collectively contribute to a comprehensive understanding of displays.
Display Technologies and Client Types
Displays leverage various technologies and support different client types, such as .NET Clients and HTML5 Clients. Understanding these technologies and client variations is necessary for tailoring displays to specific platform requirements and user experiences.
→ Read more about Display Client Types
WPF and HTML5 Automatic Conversion
Displays Module implements the user interface for the execution of your solution. The drawing of a display itself is covered in the next chapter, "Drawing User Interfaces." First, it is necessary to understand the various concepts and features related to creating and using the User Interface Displays.
Desktop and Web sharing the same configuration
The Displays Module allows the creation of screens to run on Windows desktops using WPF (Windows Presentation Foundation) technology or in web browsers using HTML5 and WebAssembly technologies.
Although you can create displays that are intended to open in only one environment, our platform supports the Portable option, where the exact same configuration can be used by both Windows/WPF clients and Web/HTML5 clients.
Users don't need to create two different types of screens for Windows and web The Portable option allows automatic conversion between WPF and HTML5 technologies. Users do not need to create two different kinds of screens for Windows and Web clients. Using the Portable option for the rendering engine creates displays that will automatically function in both HTML5 desktop and WPFweb environments. This enables running on the web browser all the displays you created for Windows/WPF.→ Read more about WPF and HTML5 Automatic Conversionfeature enables our users from previous releases to use the screens they created over the years on Windows desktops and open them directly in web browsers with no rework or modifications.
For Windows WPF, you can access the displays using the Rich Client (installed on the client computer) or a Smart Client (ClickOnce, no installation required) loading from supported browsers.
For Web HTML5, no installation is required; you can use it on desktop or mobile devices with any browser compatible with HTML5/WebAssembly (which most browsers currently are).
Process Screens and Dashboards
Process screens and dashboards are specific layouts within displays that organize graphical elements for different data visualization purposes. They contribute to the overall structure and design, enhancing the user experience.
→ Read more about Responsive Dashboards.
Display Modes and Stretch Options
Display modes and stretch options influence how information is presented on the screen. Whether configuring modes for specific contexts or stretching elements for responsiveness, these options impact the visual output.
→ Read more about Display Modes and Stretch Options.
Configuring the Displays Module
Manage displays by organizing records, including exporting, importing, inserting, renaming, and removing them. Design visual interfaces and control logic, and define layouts for component arrangement. Configure startup conditions, display behaviors, and user interface customization. Import external images for visual elements and use standardized symbols for consistent design. Set colors for visual consistency, enable multi-language support for global usability, and facilitate metric and measurement conversions.

Creating New Displays
You can create a display in two sections of the software: Displays/List and Displays/Draw. These interfaces enable the creation and management of new displays.
To create a display on List:
- Navigate to Displays/List.
- Click the
button at the top to open the 'New Display' popup window. - Define the Name and Description of the display.
- Define the Rendering Engine. This configuration item has three options: Portable (available for WPF and HTML5), WPF Only, and HTML5 Only.
- Define the Panel Type for the display. This configuration item has two options: Canvas and Dashboard.
The Canvas option allows for manual positioning and sizing of elements.
The Dashboard option automatically resizes and repositions elements, organizing the display into predefined regions. It provides a structured and uniform layout, ensuring that elements adapt to different screen sizes and resolutions without manual adjustments. - Optionally, choose a Template for the display. If you do not select a template, a blank page will be created by default.
- Finally, press the OK button to finish the display creation and close the popup window.
To create a display on Draw:
- Navigate to Displays/Draw.
- Click the
button at the top to open the 'New Display' popup window. - Follow the same procedure as for Displays/List.
Working with the Displays Module
Creating the User Interfaces
The software platform technology stack includes several features and tools to create and deploy real-time displays for advanced process control and visualization.
→ Learn How with Drawing the User Interface.
Enabling Multi-Monitor Support
The multiple monitor feature enhances solutions to support various screens, which is useful for enterprise Network Operations Centers and Operations Control Rooms. To activate this feature, navigate to Displays → Client Settings and select Enable MultipleMonitor. This option is available exclusively for Rich Clients.
→ Read more about Client Settings.
Self-Aware Displays
The Asset Monitor component explores the asset tree and allows navigation through standard and HTML5 displays at different levels. Each level can have its own displays or use a display that populates its content with symbols linked to each sub-node in the asset tree.
→ Read more about Self-Aware Assets Displays.
A Process Screen represents a process diagram. When resized, the elements keep their relative position.
A Dashboard Screen is for data presentation where the UI components are placed on a grid, according to the size of the Container window.
When using process screens, there are various ways to specify the responsiveness for resizing, such as stretching proportionally or other options. That behavior is defined in the drawing tool or the Display Settings.
When using Dashboards, you are automatically creating responsive UI interface.
Windows Specific Features
Although the platform tries to keep the Windows/WPF and Web/HTML5 experiences of the displays as similar as possible, there are features available only when running WPF displays on Windows, due to intrinsic limitations of the web browser.
Those features include;
Easily setup for Multi-Monitor applications.
Process Control execution mode disables the Windows Task Switch.
Those requirements are useful for enterprise Network Operations Centers and Operations Control Rooms. To activate this feature, navigate to Displays Client Settings
Designer and Runtime Themes
An extensive set of light and dark themes, including high-contrast options, provides better comfort and visibility when creating the solution, as well as for operators.
The built-in tools enable the easy creation of solutions that will be delivered with theme support, requiring no extra effort.
Localization and Internationalization
The platform allows the easy creation of solutions that, without the need of modifications, can run in various settings for language and internationalization.
It is possible for two Operators to access the same server, using distinct choices of UI language and Engineering Units, and changing its settings for their local User Interface.
Smart Symbols
Smart Symbols
The Drawing tool includes a library of around 2,000 Smart Symbols, graphical elements typically used in industrial applications. Many of these symbols are more than just vector images; they also have dynamic behavior that allows direct mapping to your tags and assets. It includes also a set of Industrial Icons, specially designed for the typical visuals on process displays.
High Performance HMI
The well-known book High Performance HMI proposed a set of standards for HMI design. Our platform fully enables the creation of solutions that support those standards, including High-Performance Graphical (HPG) palettes in its themes and hundreds of ready-to-use symbols created following those specifications.
Advanced Components and Controls
For advanced graphical interfaces, such as GanttCharts, TrendCharts, DataGrids, PdfViewers and more, a set of Graphical Components for WPF and Web is included. Additionally, third-party controls can easily be used in the solution.
Self-aware Applications and Dynamic Displays
Previous generations of SCADA and HMI typically had the drawing and mapping of their data fixed to the tags and process variables. At most, they allowed the same drawing to point to different assets, as long as the assets were similar. Our platform, being a new generation, also allows the dynamic creation of complete graphic displays according to the data being connected.
These data-centric applications can have their user interface created automatically based on the assets found in the data model. Typically, these applications are organized around a unified namespace, an MQTT broker, or OPC UA servers.
Using the TagProvider feature, our platform can establish a dynamic connection with those systems, selecting the best UI elements according the data found on the connected servers.
Learn more about data-driver user interface on the Tutorial MQTT and Dynamic Displays.
