In the first category are files that are created from the other files. Files and folders which git can ignore usually fall into two categories. Git uses this file to determine for which files or folders it can ignore the changes. gitignore file is very important when you’re using git. Only structured text works on any system. Then it is very difficult to make sense of the changes between versions. But, if you’re working on a system that doesn’t have the TcCompare tool, you have a problem. It helps you to merge changes or view differences between versions. That is why Beckhoff made the TcCompare tool. For example, if you switch the order of two statements in a function block diagram. Furthermore, minor changes in function block diagrams can lead to a code difference of dozens or hundreds of lines. When you’re using anything other than structured text, the raw text files are unreadable. In the end, it all boils down to the readability of the raw text files. With that said, I’ll now explain why structured text works much better than function block diagrams for source control. These are impossible to implement with a function block diagram, or a lot more verbose than in structured text. Take for example a simple for loop or an if-else statement. It is so much more versatile than the others. I think that structured text is the future of plc programming. I’m a bit biased on the structured text front. From my personal experience with function block diagrams and structured text, I’ve noticed a big difference in how well they work under source control. Some of these implementation languages work better with source control systems than others. Think of ladder logic, function block diagrams, and structured text. There are various implementation languages for PLC code. The first step for seamless TwinCAT source control starts with the selection of the implementation language. Choosing the right implementation language Or you can play this game which teaches you some git commands.īut even after gaining some experience, I still like to use one of the GUI’s for most git commands. You’ll learn to use the git command line with time. If you’re getting started with git, I recommend installing a git GUI like SourceTree, GitKraken, or ungit. So much so, that there are billion-dollar companies like GitLab and GitHub, which provide a more user-friendly interface to git. So you can do version control on any document on your computer.Īlthough git and the ideas behind it are very powerful, it is also very difficult to master. Here you always need a connection to the central source control system to add your changes to the history. This process contrasts with centralized source control. Once they are done, they can merge their changes into the main codebase. Each developer can make local changes first and save each incremental step. Distributed means that every developer has a copy of the full history of the code on their machine. Git is a free and open source distributed version control system. The most popular versioning control system is git. You no longer have to use the filename for versioning. So, if you discover that a feature you implemented doesn’t work out as you planned, it is easy to revert the changes. Since it saves all your changes, it is easy to return to a previous state of your code. Source control, also known as version control, allows you to save your code incrementally in a database. If you’re not yet familiar with source control then it is something that you should absolutely learn as a software developer. You might also like my new post on pre-commits. The main focus is git, but many points apply to other source control systems as well. In this post, I share some tips and tricks I picked up along the way. Yet, there is little information online on how to do it for TwinCAT projects. Source control is an essential tool when you’re developing software.
