Open Source HMI Software

Snap7, through three specialized components: Client and the inedited Server and Partner, allows you to definitively integrate your PC based systems into a PLC automation chain. Designed to transfer large amounts of hi-speed data in industrial facilities, it scales easily, down to small Linux Arm boards such as Raspberry PI. Hi level object oriented wrappers are provided, currently C/C++, .NET/Mono, Pascal, LabVIEW, Python with many source code examples. Very easy to use, a full working server example is not bigger than the “Hello world”. Many projects/makefiles are ready to run to easily rebuild Snap7 in any platform without the need of be a C++ guru. Very detailed documentation provided.

PiXtend® multiplies the capabilities of the Raspberry Pi and forms the ideal basis for challenging projects. The PiXtend Platform provides numerous digital and analog inputs & outputs as well as a variety of serial interfaces like RS232, RS485 and CAN. In this repository you can find the Linux C library called "pxdev" that can be used to develop your own Linux applications for the PiXtend system (V1 & V2). Sample programs for every PiXtend version are also included in this repository. The build file compiles them all - the library itself and the sample programs.
