Each topic or feature is described separately with hands-on examples, we have a plan to develop YouTube Video and those will be posted later.
If you want to learn TwinCAT HMI, this site gives you all the knowledge you need, let start.
Installation, IDE, Architecture and the First Example (Linear Gauge)
The HTML5 based HMI provided by Beckhoff is the most intuitive solution in the market today. TwinCAT now integrates the Human Machine Interface directly into the familiar environment of Microsoft Visual Studio®. Programming is unnecessary as the configuration is handled with ease using the TwinCAT HMI graphical editor. Follow these steps to install and test a linear gauge example.
TwinCAT HMI Symbol Data and Binding
In TwinCAT a variable is called symbol. This symbol can be mapped or linked to PLC variable. Some symbols can be local to HMI server. That means it is not read from PLC. This page will describe how do we make the link between HMI and the PLC. This also explain the event system. So click here to continue.
TwinCAT HMI User Control
There are many concepts in TwinCAT HMI. User control is a reusable block that can be created and used with different parameters. We shall show how to use different concepts for building HMI that can use reusable HMI components. All these are described with tips and tricks. Please follow this link.
TwinCAT HMI View
One of the major ideas for HMI is to display device data online and collect users commands from the users and execute those. Logically we can show different devices statuses in different views if needed to avoid complexity and improve the look and feel. All these are described with tips and tricks. Please follow this link.
TwinCAT HMI Region and Content
There is a various concept in TwinCAT HMI. We can split the desktop into different areas and we can display different content in different areas. All these are described with tips and tricks. Please follow this link.
How to Change Device Setting in HMI
We often need to adjust settings for different devices in the PLC. If we want to set the motor startup time and motor shutdown time (as an example). We need a way to show the settings to a user so the user can edit them or read them. This article is just for this. Continue reading with full sample code.
TwinCAT HMI CheckBox and ComboBox
Typically we use ComboBox for selecting from a list of items. CheckBox is used to indicate if some variables are true or false in the HMI. Some tips and tricks are described here. It may be easy if you know but if you don’t know then it can take lots of time to find. Please follow this link.
Establish link between HMI and OPC Server
TwinCAT HMI can read data from the PLC, it can read from the custom library (extension) or from the OPC UA Server. The data from the OPC UA server can be treated in the same way as we do for ADS. HMI does not make any difference between where the data is coming from. Continue reading with this link.
A Data Historian is a type of time-series database designed to efficiently collect and store process data from an automation system. Continue reading more about the historicization of data for automation systems with sample applications…
Software localization helps in creating a more user-friendly user experience for a diverse range of customers. When more people start using your platform, then more people will be interested in your software. Learn how you can localize your SCADA/HMI software for TwinCAT platform, Continue reading with a complete working sample.
The management of users on any software system is critical to the security of the system and the organization. Proper procedures should be in place within the organization to identify the proper permissions each new user should receive. Each person or user may not have equal rights, for example, an expert-level user who knows how the system works as compared to an entry-level worker does not know. So there might be potential risks of misusing the system. This section just describes different features with samples for the TwinCAT environment.
Add user icon to HMI
Most users want to add their own icon based on their choice. Beckhoff HMI provides a default icon that may not be enough in most cases. We shall provide an example with source code and a video tutorial on how to add a custom image to the HMI project so during run time user or the admin can set the image from a custom image for an example from a PNG file. Continue reading.
Alarms and Events
Alarms and Events provide a way to inform users about interesting issues about the plant. The issue or the notification could be critical information or something like a nice to know type. Continue for more…
Recipe types and recipes. A recipe type is a general description of a set of symbols, based on these we can create a different type of recipe. These are comparable to class (recipe type) in object-oriented programming from where we can make instances of a class (recipes) with different attributes. Learn more with example.
Variables mapping and subscription using JS
You have lots of devices in the fields managed by PLC. You need to link all variables from HMI to individual field devices. You will do one by one? We shall explain what can be done for this, continue reading and download the sample for testing.

How to develop Communication module between PLC and PC
We can connect a PLC from a laptop by using ADS communication. This interface can be used by different programming language. In this chapter we shall use C# (see our C# tutorial). Continue with this link.
How to publish to HMI Server
When we are satisfied with our development then we need to publish the SCADA /HMI to a remote server so our operator can access it and use it. We need to install HMI Server (not HMI Engineering to the machine). Click on the image below to see how to publish HMI to serves.
Animation in TwinCAT HMI
It is very easy to use the animation framework in the TwinCAT HMI framework. The following sample will show and explain a bit how to animate an object and how to get events from the animation. The full sample code is available as well. Continue reading the article and see how easy it is.
