About INTERNET BROWSER

INTERNET_TARAYICISI is a user control that enables web pages to be embedded in EOS SCADA screens. It provides a practical visual bridge between the SCADA application's own process visualization and web-based third-party applications.

WEB CONTENT WITHIN THE SCADA SCREEN

Equipment Configuration Center

The web-based configuration interface of a third-party device can be displayed in a section of the SCADA screen.

This approach is particularly useful in systems where a manufacturer's web interface provides configuration, maintenance, diagnostics, or service functions for equipment. For example, a web-based configuration screen accessed through the IP address of a device on the network can be displayed alongside the corresponding equipment in the SCADA project.

Access Without Leaving the SCADA Screen

Displaying a web-based equipment interface in a user control within the SCADA screen, rather than opening a separate application window, can help operators keep monitoring and support workflows within a single workspace.

Web Content Within SCADA

The basic concept of the control is simple: a web address is assigned to a designated area of the SCADA screen, and the web content is displayed within that area. This arrangement can be useful when equipment's own web-based service interfaces need to be available on the same screen as the SCADA visualization.

Device Settings

Parameter and configuration screens.

Diagnostics

Status, error, and service information.

Web Monitoring

The third-party device's own visualization.

Two Web Addresses and Automatic Switching

According to the source code, the control can define two separate web addresses. The URLAddress1 and URLAddress2 fields specify the two addresses, while PageTransitionTime defines the interval between pages in milliseconds.

URLAddress1
Web Address 1
http://device-1
→
Page Transition Time
300000 ms = 5 minutes
→
URLAddress2
Web Address 2
http://device-2

Example Usage

The default value of 300000 ms corresponds to 5 minutes. For example, an information area can be configured to alternate between an equipment's web-based status screen on the first page and another piece of equipment's maintenance or configuration screen on the second page.

Potential SCADA Applications

Third-Party Equipment Configuration

Configuration screens for devices with manufacturer-provided web interfaces can be made accessible within SCADA.

Maintenance and Service

A dedicated web area on the SCADA maintenance screen can provide maintenance personnel with quick access to an equipment web panel.

Network Devices

It can be used to display status or configuration pages for network and communication equipment with web-based management interfaces.

IP Cameras and Video Monitoring

It can be used with systems that provide web-based video interfaces, subject to appropriate technical and security conditions.

Web-Based Dashboards

If a separate web application is available for production, energy, or equipment performance, the relevant view can be displayed on the SCADA screen.

Technical Support Screens

It can provide an access point for technical support, device diagnostics, or service applications running on the local network.


General Properties

The properties defined in the source code and their EOS Turkish equivalents are listed below.

Property EOS Turkish Equivalent Default Description
UCType Control Type INTERNET_TARAYICISI Specifies the type of the user control.
UpdateInterval Update Interval 1000 Specifies the general update interval of the control.
DecimalPoint Decimal Places 0 Specifies the number of decimal places used for the control's numeric display.
UCBackColor Control Background Color Transparent Specifies the background color of the control.
UCForeColor Control Text Color Black Specifies the text color of the control.
UCFont Control Font Arial Narrow 8.25 Specifies the font used by the control.
URLAddress1 First URL Address http://www.google.com Specifies the first web address.
URLAddress2 Second URL Address http://www.yahoo.com Specifies the second web address.
PageTransitionTime Page Transition Time 300000 Specifies the interval used to switch between the two web addresses. The value is in milliseconds.
UpdateActive Update Active false Specifies whether the update behavior is enabled.
MaximizeScreen Full Screen false Specifies the setting that controls the full-screen behavior of the web content.

Example Industrial Scenario

Consider a facility where process values for a pump station are monitored on the main SCADA screen, while access to the manufacturer's web-based service screen for the pump drive is also required.

Monitoring and Service on a Single Screen

  1. Select the relevant pump equipment on the SCADA screen.
  2. Link the pump's web interface to the control area using URLAddress1.
  3. The web interface of a second device can be specified as URLAddress2.
  4. Use PageTransitionTime to define the interval for switching between pages.
  5. When necessary, perform configuration or diagnostic operations through the web page using the device's own authentication mechanism.

Network and Security Considerations

Security for Web Content

Adding web content to a SCADA screen can connect the SCADA operating environment with other systems on the network. Therefore, only necessary and trusted addresses should be used; HTTPS should be preferred over HTTP whenever possible; and access permissions, network segmentation, firewall rules, and the third-party device's own authentication mechanisms should be evaluated separately.

Some industrial web interfaces may not be displayed when embedded because of browser security policies or server-side policies such as frame-ancestors. This depends on the web application's security configuration.

Web browser-based access is documented in industrial HMI products for use cases such as accessing devices' built-in web pages, intranet/Internet content, and web-based applications. For example, Rockwell documents a Web Browser object that accesses specific URLs from within an HMI, while Siemens documents web-based device configuration and HMI access scenarios. citeturn0search2turn0search9turn0search1

Recommended Approach to SCADA Screen Design

Dedicated Area

The control should have a clearly defined area appropriate to its function, preventing web content from overlapping process graphics.

Address Management

URLs should be stable and documented wherever possible, and should direct users only to the devices or applications required.

Transition Interval

When two addresses are used, the page transition interval should allow the operator enough time to read the content and intervene when necessary.

Authorization

The web page's own user authentication and SCADA user authorization should be considered together.


Conclusion

INTERNET BROWSER is a flexible user control that can transform a SCADA screen from an area used solely to display process data into a workspace that also accommodates the necessary web-based technical interfaces.

Particularly when dealing with web-based configuration, diagnostics, and service screens for third-party equipment, it can provide a practical solution by allowing operators or maintenance personnel to access the relevant web interface without switching to a separate application. Support for two addresses and time-controlled transitions also extends its use to information displays and rotating technical pages.

Key Concept

SCADA + WEB: Bringing process visualization and the necessary web-based technical interfaces together within the same screen architecture.
