The OpenPLC runtime web interface is used to load and monitor logic. I loaded the OpenPLC runtime on a Raspberry PI. See for specific instructions for your installation.įor my installation I put the OpenPLC editor on my Ubuntu PC so that I could do remote configuration. The OpenPLC software comes in three packages, a logic editor, the runtime component, and a graphic builder. Finally I will have these projects pass their data via Modbus TCP to a Node Red dashboard. ![]() In this article I will create three small Raspberry Pi projects using the IEC 61131-3 ladder logic, function blocks and structure text programming languages. OpenPLC is open source software that runs on a Raspberry Pi, Linux or Windows PC and it offers users a great way to learn industrial control concepts, programming languages and communications protocols. If you are interested in looking at an industrial controls approach to your automation projects then OpenPLC is a good package to consider.Ī PLC (Programmable Logic Controller) is an industrial hardened hardware device that manages I/O and logic using the IEC 61131-3 standard. For home automation projects there are a lot of good software packages like Home Assistant and Node Red that can be used to control and view sensors and devices.
