In this video, we will show you how web-based, low-code technologies are being used to solve simple industrial automation applications and why we believe that web-based, low-code technology will continue to become more important for companies involved in industrial automation.

Just like the web-based, low-code revolution has made traditional software development easier, faster, and more accessible, web-based, low-code technologies will improve the way engineers solve simple automation applications.

One of the main advantages of web-based programming is that any device with a browser can be used to program a controller.

Since the development environment runs in the browser,
- You don’t need to install a heavy development environment on your machine,
- You don’t need to buy an expensive license for the development environment,
- You don’t need a powerful machine to run the development environment.

Since web-based programming reduces the cost and requirements of programming controllers, a web-based development environment makes it much easier for anyone to write PLC programs and develop Industrial IoT applications.

In this demonstration, we will show you how to create a simple PLC program and visualisation using web-based, low-code technology.

Since Weidmüller is the industry leader in web-based, low-code technology, we will use a Weidmüller u-control 2000 controller for this demonstration. This controller is designed to make automating simple tasks fast, easy, and reliable.

The u-control controller is at the heart of the Weidmüller’s u-mation platform.

The USB port on the u-control controller is a service port and in most situations, you will connect to your u-control starter kit using one of the two Ethernet ports that are available on the u-control controller instead of the USB port.

However, an enormous advantage of connecting to the controller using the service port is that the USB connection supplies enough power to power the controller. This is a very useful feature when doing benchtop testing without I/O modules or development.

Before we can write a control program, we have to configure the hardware for the control system. In low-code applications, the goal is to minimize the amount of work that a user has to do to get up and running.

For this reason, u-create web has a powerful hardware detection feature that automatically detects the hardware modules connected to the u-control controller and adds them to the project.

With the Function Block Diagram programming language, we can develop simple control programs using a catalog of available Function Blocks.

In the Live View, we can see the current mode of the controller and monitor the values of the physical inputs and outputs that are part of the application.

Since the visualisation is hardware-independent, this visualisation can be accessed by any device on the network that has a browser like an iPad or an Android phone.

Since the visualisation application is running on the controller, we don’t need a separate HMI device to run and view the visualisation application.

Boreal Light use the u-mation platform to power their Water Kiosk product. The Water Kiosk is a water treatment machine that provides clean drinking water to rural villages in Africa.
