The intention was to create something that you could buy very cheap, primarily for students and such to learn how to program 61131-3.</p> <p>As I&rsquo;m primarily working with TwinCAT 3, which is based on CODESYS, I&rsquo;ve been thinking about building a really cheap 61131-3 compatible PLC based on the RPI and the CODESYS target. I didn&rsquo;t just want it to be one board laying around in my home, but I also wanted it to have the &ldquo;industrial&rdquo; feeling, and luckily I found a perfect development board + case for me to initialize the project. Now that it&rsquo;s finished, I have a PLC running an EtherCAT master in the CODESYS runtime for almost no money at all.</p>
