Example TrafficLight Web Visualization

In this example, we create a simple web visualization of traffic lights on the RevPi Connect using CODESYS WebVisu. We are using a Connect+ 16 GB feat CODESYS Multi Core with CODESYS Control for Raspberry Pi MC SL and a RevPi DIO module for this example.

Description: The application runs with RED light and GREEN light duration of 10 seconds and a YELLOW light transition of 2 seconds in normal mode. There is also a night mode switch. In night mode, only the YELLOW light flashes.

If you have a license for Single Core, you can change the target like this:

Right-click on the “Root Device” CODESYS Control for Raspberry Pi MC SL in the CODESYS device tree.

  • Click on update device.
  • Select CODESYS Control for Raspberry Pi SL.

The CODESYS Control device target for the example is changed from MultiCore to SingleCore.

You need to add :8080 (standard value for the CODESYS web visualization) to the IP address of your RevPi device in your web server in order to open the visualization.
