倍福Ads协议通信测试

测试环境：vs2015 + TC31-Full-Setup.3.1.4022.30.exe

首先需要安装TC31-Full-Setup.3.1.4022.30.exe

本例子是用本机作测试，如果使用远程plc控制器作测试，改成实际的IP和PORT即可

添加C#窗体程序，下述是读取的结果

添加plc程序

启动plc：第一步 Active Configuration,第二步Restract TwinCat System(绿色按钮),第三步登陆

添加plc程序：新建TwinCAT Project工程，取名为PLCPro,然后在文件夹PLC下新添加一个取名为Test1的standard PLCProject,然后在DUTS中添加一个DUT结构体plcstructure,并添加如下内容：

TYPE plcstructure :
STRUCT
    plcs1:BOOL;
    dummy1:BOOL;
    dummy2:BOOL;
    dummy3:BOOL;

    plcs2:INT;
    dummy4:INT;

    plcs3:DINT;
    plcs4:REAL;
    plcs5:LREAL;
END_STRUCT
END_TYPE

在POUS文件夹的Main（Pro）下面添加:

PROGRAM MAIN
VAR
    BoolTest :BOOL;
    IntTest:INT;
    LongTest:DINT;
    SingleTest:REAL;
    DoubleTest:LREAL;
    StringTest:STRING;
    readstringlen:INT;
    plcstruc :plcstructure;
    plcarraytest:ARRAY[1..5] OF INT;
END_VAR

启动plc

启动后，运行C#窗体。
