Snap7 project for PLC data exchange
Snap7 is an open source project to communicate with Siemens PLC (Programmable Logic Controller).
It's multi architecture, are supported : Intel 32/64, ARM 32, Sparc, MIPS, and actually it runs under Windows (from NT4.0 to Windows 10), Linux, BSD, Solaris, OSX, Android and Arduino.
And, finally, today it also works in ReactOs 0.4.2.
I didn't made a "port", now it just runs using the Win32 dll released.
If someone is interested of creating fee-free ReactOS HMI/Scada, now it's possible to exchange data with S7 PLC (all the models).
Released under LGPL 3.0.
To avoid misconceptions, Snap7 it's a library for programmers, the image refers to a demo program that uses the library.
