There is also a dedicated section for downloading the software needed to programme the device.
The partnership with Arduino Pro, in fact, makes it possible to integrate the brand's open source platform and the simplicity of programming Arduino sketches, without giving up the suite of traditional languages with reference to the IEC 61131-3 standard for PLC programming, such as LADDER, FBD, etc.
So let's find out how to connect it and the first steps to start programming.
