![]() ![]() I also suggest you learn about MVVM (Model-View-ViewModel), how DataBinding works, and start using INotifyPropert圜hanged and ICommand on your app. You can roll your own, it’s completely fine. There are some examples of custom navigation on the website. WPF navigation is based on swapping UserControls inside a Window. ![]() Now you probably want to create more pages and a navigation system so you can switch pages back and forth. ![]() MVVM and frameworks to navigate between multiple windowsĪt this point you can show values from plc to the screen, and use buttons and textbox to change values. But while on open source you can see the code and run away if it’s total garbage, without even the need to try it, on commercial drivers you can’t see the source code. I don’t have a specific recommendation here. However with commercial drivers you get assistance and people dedicated to fix your problem. And often multiple people jumps on board and they improve the open source driver by submitting issues or patches. Sometimes open source drivers have better quality than commercial ones. My take on commercial drivers vs open source ones It is important that you look for how active is the project, if there is a manual, how many issues are open and resolved, is anyone answering to the issues, etc. You can run a search, expand code, commits, filter for language, and you’ll get a list of repositories.įor example this is a how an advanced search looks like filtering for code and C# So how do you search for a driver for your plc ? The answer is, you either pay for a commercial one, or you use an open source one and search on Github. On this website I talk about some driver for the major brands, but market is always changing. Once you can put labels and buttons on the window, you’ll probably want to connect a plc to the app. NET Core 101Ĭonnecting a PLC to the app: driver selection To show your first window with WPF, you can refer to another Microsoft playlist: Desktop and. WPF has full access to the operative system and you want exactly that for an HMI. I would discourage the use of UWP, because it’s sandboxed and has too many limitations. There are tons of technologies available out there, what I’m referring here is WPF, or Windows Presentation Foundation.Īlternatives are Windows Forms (that also uses C#), Web Apps on Electron, Win32 apps, other proprietary frameworks like LabView etc. This means you have to learn the Windows SDK to develop Windows apps. HMI are visual application, so once you know the basics C# and can run a console app, you need to display at least something to the screen. If you are into books, I always liked Microsoft Visual C# Step by Step, but I believe there are tons of valid books out there, that’s what I read personally back then. ![]() In particular you can check playlists in the beginner seriesĬ# 101 is for example a series of videos focused on learning the basics of C#. To learn C#, Microsoft has a YouTube channel that has plenty of tutorials. It often offers discounts, 2 free weeks, free weekends, whatever. The paid resource that I use the most is Pluralsight. If you need to get a project done on a certain deadline, it’s not a big deal to pay for answers. If you are a student, then it’s fine if you spend tons of hours searching YouTube tutorials or blogs. While I’m not affiliated to the websites, I believe that time is an asset and you should choose carefully where you spend your time. However I will also link paid resources in this article. I am a believer on free education resources. My take on free online resources vs paid ones I personally prefer videos instead of books for my learning, so here you’ll get more video resources. I’m also mentioning some advanced topic, so just scroll down if you are already familiar with C# and WPF. Hopefully this article will be a path for these people, a guide on learning how to do an HMI step by step and get consistent progress. However quite a chunk of emails that I receive are from people getting started with C#. I’ve always published content targeted to mid-level C# developers. ![]()
