OpenPLC on Linux
These instructions are targeted for Debian-based distributions (like Ubuntu, Mint, Kali, etc).
The best way to get OpenPLC files into your system is by using git. Usually, git comes preinstalled on most Linux distributions. If for some reason you don’t have git installed on your system, you can install it by typing:
sudo apt-get install git
To install OpenPLC type these lines on the terminal:
git clone https://github.com/thiagoralves/OpenPLC_v3.git cd OpenPLC_v3 ./install.sh linux
The installation process will take a while (up to 1 hour depending on your system). Meanwhile, grab a [insert your favorite beverage here] and relax! Once OpenPLC is installed, just reboot your device and it will start automatically after boot.

Just go to the Users menu, click on the OpenPLC User and change the information as you like.
Once you save the changes you will be prompted to login again. Just login with your new credentials and you will be good to go!
Setup Slave I/O
A great way to use OpenPLC on your Linux machine is with slave I/Os. Therefore,
your Linux machine can run OpenPLC Runtime and act as a Soft-PLC controlling
real boards configured as Slave I/O devices. Go to the Getting Started page
and follow the instructions to setup one of the supported platforms as slave
devices. Then, through the web interface, add your slave devices on the
“Slave Devices” menu. Keep in mind that slave devices are attached to address

My First Project
The Reference menu on this website has a nice tutorial that
teaches you how to create your first project.
However, if you’re in a hurry, you can download the official Hello World
project, which is basically one rung, a button, a timer and a coil, all
connected together. The button is attached to
%IX0.0 and the coil is attached
%QX0.0. When the button is pressed and released, the coil is energized and
remains on for 2 seconds, and then turns off.
Download the project below and open it on OpenPLC Editor. Click on Generate program for OpenPLC Runtime in order to compile the diagram into a ST file. Then upload the ST file to the OpenPLC using the web interface.
