Main features  Native multi-architecture design (32/64 bit).  Platform independent, currently are supported Windows (from NT 4.0 up to Windows 8), Linux, BSD, Oracle Solaris 11 and Mac OSX.  Multi CPU support : Intel and AMD i386/x86_64, ARM, Sun Sparc, Mips.  Fully scalable, starting from blade servers down to Raspberry PI board.  No dependence on any third-party libraries, no installation needed, zero configuration.  Three different native thread models for performance optimization: Win32 threads/ Posix threads / Solaris 11 threads.  Two data transfer models: classic synchronous and asynchronous.  Two data flow models: polling and unsolicited (PLC transfers data when it wants to).  Two specialized ports : Settimino and Moka7 allow you to communicate with S7 PLC with Arduino or Android phones.

可直接读取PLC的I,Q,M,V 可写入PLC的I,Q,M,V 包含B,W,D等寄存器的读取写入 以Q区读写为例: a = c.WriteData('Q', 0.0, 1) print(a) a = c.ReadData('Q', 0.0) print(a) a = c.WriteData('QB', 0, 2) print(a) a = c.ReadData('QB', 0) print(a) a = c.WriteData('QW', 0, 258) print(a) a = c.ReadData('QW', 0) print(a) a = c.WriteData('QD', 0, 65538) print(a) a = c.ReadData('QD', 0) print(a) 根据返回值可判断当前错误状态

Snap7开源控件是用C语言写的,其控件源码可直接去官网下载,但是测试通信例程比较少,与西门子PLC300 ,400 ,1200 ,1500 PLC都可通信,通过设置槽号就可以,这是是通信例程CSharp、用VS2010或其以上版本均可打开。
