Each topic or feature is described separately with hands-on examples, we have a plan to develop YouTube videos and those will be posted later.
If you want to learn TwinCAT HMI, this site gives you all the knowledge you need, let’s start.
Installation, IDE and Architecture
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 set up the environment.
Create your First HMI within 8 minutes
There is no limit to how good you can make your HMI, it depends on your imagination, creativity, and talent. We need to start somewhere. If you have installed the environment you can make your first HMI within 8 minutes. Follow these steps to build your first TwinCAT HMI.
How to build Linear Gauge example with PLC code
We shall learn all the techniques from the TwinCAT HMI SDK step by step. It is a good idea to develop some simple HMI applications to motivate ourselves. Follow these steps to build an HMI that can display data from PLC ( linear gauge example.)
TwinCAT HMI Symbol Data and Binding
In TwinCAT a variable is called a symbol. This symbol can be mapped or linked to the PLC variable. Some symbols can be local to the 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 explains 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.
User Control consist of few other user control
A typical automation software model is built by reusing an existing model or some basic elements. For example, we can build a user control for a proximity sensor, pressure sensor, etc. Now if we build a pump’s user control, we can reuse the proximity sensor user control, pressure sensor user control plus other Beckhoff other basic user control. This article explains how we can manage with a complete working sample, continue reading.
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 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.
TwinCAT HMI CheckBox, ComboBox
Typically we use ComboBox for selecting from a list of items. A 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.
TwinCAT HMI Data Grid View
TwinCAT HMI Data Savings
TwinCAT HMI Data Savings, TwinCAT HMI can be configured in different ways. Here on this page, we explain the HMI configuration in a generic way and especially we describe how to store data in the HMI area, same data will be saved by the TwinCAT extension in the SQLite area. For small data, it looks like it makes sense to store internal/server variables. In other cases, we can use MS SQL or SQLite database. So click here to continue.
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 the 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 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 examples.
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.
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 it one by one? We shall explain what can be done for this, continue reading and download the sample for testing.
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.

Rotation by using animation framework around a point triggered by PLC variable
We want to rotate an image around the center of the image by animation framework. How can we achieve that? Continue with a full complete explanation.

How to show SQLite Data to TwinCAT HMI
If we want to show or manage small data for our HMI, should we use a file or some light database? TwinCAT HMI offers the possibility to display tabular data to the user’s interface. This article shows how to read the data from the SQLite server and display it to the interfaces. Continue reading the pages.

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 languages. 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

Ask questions related to Hemelix sample code and design at Google group https://groups.google.com/g/hemelix
When you have many UI controls on the Desktop or content view, in which order those control are loaded? If you see the HTML code then the last DIV element is loaded at last. So if you want to do something with this then you could use this. This can be monitored by observing the Attached event.
Sometimes the whole HMI may not be started (it may block at step 08 during the HMI loading). One reason could be that the following highlighted file is corrupted, it can be regenerated automatically when we build and load the solution.
