There is two ways to include the Industrial Shields library in the Arduino IDE.
(1) Automatically: USING the Arduino IDE
Open The Arduino IDE.
Click on: Sketch – > Import library…
Then Search Industrial Shields on the Library Manager
and click on Install.
To verify the installation you can go at:
File -> Examples -> Industrial Shields
How to use the Industrial Shields library in the Arduino IDE: (NOTE: This example also works for any other library you want to charge on the Arduino IDE).
Click on: “Clone or download”
After that download the zip file on your desktop.
2. Add the library on the Arduino IDE.
After choose the arduino-IndustrialShields-master.zip the library have to be charged. To verify if the library is added correctly you can see the library on:
//File-> Examples -> IndustrialShields
3. Now you can open an example to start to programm a PLC.
It is not necessary to use the Industrial Shields library to program the Arduino Based PLCs because of all PLCs use an Original Arduino board inside.
