OpenPLC is an open-source Programmable Logic Controller that is based on an easy to use the software. The OpenPLC project was created in accordance with the IEC 61131-3 standard, which defines the basic software architecture and programming languages for PLCs.
OpenPLC is mainly used on industrial and home automation, the internet of things, and SCADA research. You can check OpenPLC in action on the short video below.
OpenPLC Editor is a software that lets you write PLC programs for the OpenPLC runtime. The programs are written according to the IEC 61131-3 standard.
The editor is very simple to use and supports all five languages defined in the standard:
- Ladder Logic (LD),
- Function Block Diagram (FBD),
- Instruction List (IL),
- Structured Text (ST), and
- Sequential Function Chart (SFC).

ScadaBR is an open-source Supervisory Control and Data Acquisition (SCADA) system that allows you to create interactive screens, also called the Human Machine Interface (HMI), for your automation projects. ScadaBR can talk to several different PLCs, including OpenPLC, which makes it a perfect companion for the OpenPLC runtime and editor.
The simplest way to install ScadaBR is by using a Virtual Machine. A Virtual Machine is a software that can create a virtual computer inside your own computer.
The following steps will guide you to download and install VirtualBox, a free and open-source Virtual Machine Monitor. Once VirtualBox is installed, all you have to do is load the ScadaBR image file into VirtualBox to have a ready-to-use ScadaBR environment on your system.
