运动控制卡应用开发教程之VB6.0

今天，正运动小助手为大家分析一下应用VB6.0开发一个总线初始化的运动控制应用。

我们主要从VB6.0的项目新建、函数库引用和PC函数使用方面讲起，最后通过项目实战——总线初始化例程讲解，来让大家熟悉它的项目开发。

在正式学习之前，我们先了解一下正运动技术的运动控制卡ECI2418和ECI2618。这两款产品分别是4轴，6轴运动控制卡。

ECI2418支持4轴脉冲输入与编码器反馈，板载24点输入，16点输出，2AD，2DA，支持手轮接口，其中特定输出口支持高速PWM控制。

ECI2618支持6轴脉冲输入与编码器反馈，板载24点输入，16点输出，2AD，2DA，支持手轮接口，其中特定输出口支持高速PWM控制。

ECI2418，ECI2618均使用同一套API函数，均支持C、C++、C#、LabVIEW、Python、Delphi等开发语言，支持VC6.0、VB6.0、Qt、.Net等平台，支持Windows、Linux、WinCE、iMac等操作系统。

以下是VB6.0

开发流程

一新建EXE工程，加载函数库。

(一)新建工程

打开Microsoft Visual Basic菜单，在“文件”→“新建工程”，选择新建“标准EXE”工程。

新建工程自带一个起始窗口，可以通过菜单“工程”→“属性”更改起始窗口。

(二)加载PC函数库

VB6.0需要对添加的dll文件进行加载，否则系统找不到函数所引用的函数库源，加载步骤如下。

1.找到厂家提供的光盘资料中的VB6.0资料。

2.将VB6.0压缩包解压，找到其中的dll库文件

3.将dll文件zmotion.dll以及zauxdll.dll一起复制放入系统文件夹C:\Windows\System32中。假如编程系统是64位系统，也要把上述文件复制到C:\Windows\SysWOW64中。

4.通过“开始”菜单→“Windows系统”→“命令提示符”或者在“开始”菜单搜索“cmd”打开命令提示符窗口，使用如下指令：

regsvr32 C:\ Windows\ SysWOW64\ zmotion.dll

regsvr32 C:\ Windows\ system32\ zmotion.dll

regsvr32命令用于注册COM组件，是Windows系统提供的用来向系统注册控件或者卸载控件的命令，以命令行方式运行。Zmotion.dll加载后，才可以调用zauxdll的函数。

可以将该条指令复制到记事本上，然后把txt文件另存为bat文件来运行。另外，一些自己下载vb6.0的额外部件也可以用该方法加载，加载后能在菜单“工程”→“引用”，“工程”→“部件”中找到对应文件，本例程使用函数库无需加载部件或引用。

(三)函数库使用

将zauxdll.bas与工程文件放入同一文件夹，方便管理。

在工程资源管理器中右键添加模块，或者在菜单“工程”→“添加模块”功能中将zauxdll.bas添加入工程。

这样就做好使用正运动PC函数库的准备了。

二查看PC函数手册，了解其用法。

(一)PC函数手册也在光盘资料里面。

具体路径如下：

(二)PC编程。

一般先根据控制器连接方式选择对应的连接函数连接控制器，返回控制器句柄。接着用返回的控制器句柄，实现对控制器的控制，大部分函数都有对控制器的指向。通常有：

Public g_handle As Long

控制器句柄是连接控制器的重要标志。

(三)通过网口连接控制器，获取句柄。

通过网口 iret = ZAux_OpenEth(“127.0.0.1”, g_handle)或者串口 iret = ZAux_OpenCom(1, g_handle)连接控制器，获取控制器句柄 g_handle。

(四)下载总线初始化bas文件

下载总线初始化 bas文件到控制器 iret = ZAux_BasDown(g_handle, sFilePath, 1)，sFilePath是对应总线初始化的文件地址，利用 CommonDialog对话框操作部件，获取对象文件地址。

总线初始化文件是基于ZDevelop编写的EtherCAT和RTEX初始化程序，通过ZAux_BasDown方式下载到控制器以直接运行。

(五)EtherCAT数据字典读写

EtherCAT数据字典读写 ZAux_BusCmd_SDORead和 ZAux_BusCmd_SDOWrite。

其中对象字典编号、对象字典子编号、数据类型是十进制输入，手册上是十六进制表示，使用时注意转换。

(六)位置环增益与速度环增益调整

松下A6B系列EtherCAT总线驱动器中：

位置环增益对应数据字典为 3100H-00H(第一位置环增益)和 3105H-00H(第二位置环增益);

速度环增益对应数据字典为 3101H-00H(第一速度环增益)和 3106H-00H(第二速度环增益);

自动选择增益参数的标志位为 3002H-00H。

具体请参考光盘资料(P315~P318)：技术资料→ECAT通讯规格篇→MINAS_A6B系列→EtherCAT通讯/选择类型。

本篇文章使用第一位置环增益和第一速度环增益，通过实时自动增益调谐设置选择是否改变增益参数。

(四)编译运行演示

1.EtherCAT连接

连接控制器后点击“下载BAS文件到ROW”按钮，打开对应文件夹，选择“ECAT初始化”文件。

通过轴数量和节点数量可以看出，以及检测到驱动器并连接成功，接下来通过控制运动现象来确认驱动器受控制。

2.测试使能

使能状态off

使能状态on

轴使能正常。

3.运动测试

通过ZDevelop软件连接对应控制器时，可以通过“视图”→“示波器”调出示波器观察。

正反转运动：

定点运动：

4.数字字典测试

在EtherCAT通讯中，数据字典3002h-00h表示运动控制中位置环增益和速度环增益是否自动改变。1-自动，0-手动。
