Back in 2007, while working as a computer tech for a chemical company, we were installing Triconex safety systems in one of the units. Having used Concept for Modicon PLCs at that time, I liked the TriStation 1131 software, especially the function block diagrams. It was always fun to convert legacy ladder logic to FBD. However, I wanted a FBD simulator without having to start a project, designate hardware, and assign tags just to test some things. I couldn’t find one at the time. So, at the same time, I knew some JavaScript, but wanted to learn more. So, I created jsBlocks. A full, expandable JavaScript FBD simulator. I’ve been toting this software around for quite a while. Now, I plan on putting the code out on GitHub or the like. I had done some more recent projects where I’ve used jQuery for a lot of DOM manipulation, but this is the original brought up to work with Safari and Chrome. Have not tested with latest Microsoft browser.
