How to Achieve Simple Screen Splitting in a WinCC Project?

Posted by on

This article primarily introduces how to achieve simple screen splitting operations through settings in a WinCC project without using a screen splitter. Two monitors display different WinCC screens respectively, operating independently and without affecting each other.

Experimental Environment:

The hardware and software environment used during the experimentation in this article:

  1. WIN7 Operating System
  2. WinCC V7.2 + update3
  3. A PC with a graphics card that supports connecting two monitors. Besides the built-in monitor, an additional monitor with a DVI interface is used.

Setup Steps:

  1. Connect the second monitor using a DVI cable.

  2. Extended Desktop Settings on the PC:

    Monitor 1 Resolution: 1920 X 1048
    Monitor 2 Resolution: 1280 X 1024

  1. Open the WinCC V7.2 software, create a WinCC project, and establish NewPdl1 as the initial screen. Additionally, create Screen 2 (NewPdl2) and Screen 3 (NewPdl3). Place two picture window controls on the initial screen: Picture Window1 and Picture Window2.

Configure the properties of the main screen, NewPdl1, to allow it to be hidden.

Configure the properties of Picture Window1, adjust its size, select "Screen 2 (NewPdl2)" as the screen name, set it as an independent window, and assign it to Monitor 1:

Configure the properties of Picture Window 2 (Picture Window2), adjust its size, select "Screen 3 (NewPdl3)" as the screen name, set it as an independent window, and assign it to Monitor 2:

  1. Size Settings for Screen 2 (NewPdl2) and Screen 3 (NewPdl3):

    Screen 2 (NewPdl2) is set according to the size of Monitor 1:

Screen 3 (NewPdl3) is set according to the size of Monitor 2:

Create additional screens, variables, alarms, etc., within the WinCC project. Upon normal operation and activation, independent picture window screens can be displayed on each of the two monitors, achieving the screen-splitting functionality. The size of the monitors and screens can be customized according to individual needs.

Operational Results:

Note:

This method represents a relatively straightforward approach to achieving screen splitting with minimal hardware requirements, simply enabling dual-screen display. For more complex screen-splitting functionalities, the use of a screen splitter and settings within the OS Project Editor can be employed.
