Configuring CODESYS Target Visualization Full-Screen Display

1 Overview

Introduces the background and applicable scope for configuring CODESYS Target Visualization to display in full-screen mode.

1.1 Background

Some users have found that the CODESYS Target Visualization interface cannot display in full-screen mode when using our ED-HMI series products equipped with a CODESYS Target Visualization license. In response to this issue, our engineers conducted analysis and testing, confirming that full-screen display for the Target Visualization interface can be achieved by modifying configuration files. Therefore, we provide detailed operating instructions to help users better utilize the CODESYS Target Visualization functionality.

1.2 Scope of Application

This application applies to ED-HMI series products equipped with a CODESYS Target Visualization license.

2 Application Guide

There are two methods to configure CODESYS Target Visualization for full-screen display:

  • Configuring CODESYS Target Visualization full-screen display via the labwc window manager configuration file;
  • Configuring CODESYS Target Visualization full-screen display via the CODESYS Control runtime configuration file;

The following sections detail the specific steps for each configuration method.

2.1 Configuring CODESYS Target Visualization Full-Screen Display via the labwc Window Manager Configuration File

2.2 Configuring CODESYS Target Visualization Full-Screen Display via the CODESYS Control Runtime Configuration File

Preparation:

  • The device is properly connected to CODESYS, and the CODESYS Target Visualization function is enabled and working correctly.

Steps:

  1. In the PC's CODESYS software interface, click the 2 button in the menu bar to start the Target Visualization.
1
  1. Open the device's command terminal window and execute the following command to open the CODESYS Control runtime core configuration file.
sudo nano /etc/CODESYSControl.cfg
  1. In the configuration file, locate the parameters in the [CmpTargetVisu] section, and add the following content; then modify the values of WindowSizeWidth and WindowSizeHeight accordingly.
HideMouseCursor=1 
WindowType=1
1

Where WindowSizeWidth and WindowSizeHeight represent the window width and height, respectively, and should be set according to the LCD screen size of the ED-HMI device:

  • For a 7-inch ED-HMI device, configure the window width and height as WindowSizeWidth=1024 and WindowSizeHeight=600.
  • For a 10.1-inch ED-HMI device, configure the window width and height as WindowSizeWidth=1280 and WindowSizeHeight=800.

TIP

  • Ensure the values for WindowsPositionX and WindowsPositionY are both 0. If they are not 0, please modify them to 0.
  • If the parameters in [CmpTargetVisu] are preceded by a # or ; symbol, please remove it.

  1. Press "Ctrl+O" to save the configuration, then press "Ctrl+X" to exit the configuration file.

  2. Execute the following command to open the labwc autostart configuration file.

sudo nano /etc/xdg/labwc/autostart

  1. The autostart configuration file may be empty, so please refer to the following two scenarios for configuration.

    • If the configuration file is not empty, configure as follows:

      1. Add a # symbol in front of /usr/bin/lwrespawn /usr/bin/wf-panel-pi & to comment out this line, which will hide the taskbar.

      TIP

      If the CODESYS Target Visualization does not display in full-screen mode after restarting the device, you can execute sudo systemctl restart codesyscontrol.service on the device to restart the CODESYS Control service.

    • ​If the configuration file is empty, configure as follows:

      1. Execute the following command to open the Wayfire window manager panel tool configuration file.
      sudo nano .config/wf-panel-pi.ini
      1. Add autohide = true to the configuration file.
