PCI-7361是一款多轴运动控制卡,可以通过VB程序实现对其的控制。PCI-7361提供了多种编程接口,包括C语言、VB、LabVIEW等。以下是使用VB开发PCI-7361板卡控制程序的示例代码:
1. 引用PCI-7361的动态链接库文件
```
Declare Function pci7361_initial Lib "PCI7361.dll" () As Long
Declare Function pci7361_home_move Lib "PCI7361.dll" (ByVal axis As Long) As Long
Declare Function pci7361_absolute_move Lib "PCI7361.dll" (ByVal axis As Long, ByVal pos As Long) As Long
Declare Function pci7361_relative_move Lib "PCI7361.dll" (ByVal axis As Long, ByVal pos As Long) As Long
Declare Function pci7361_stop Lib "PCI7361.dll" (ByVal axis As Long) As Long
```
2. 初始化PCI-7361控制卡
```
Dim rtn As Long
rtn = pci7361_initial()
If (rtn <> 0) Then
MsgBox("初始化控制卡失败!")
End If
```
3. 进行轴运动
```
' 进行原点回归
Dim axis As Long
axis = 0 ' 轴号
rtn = pci7361_home_move(axis)
If (rtn <> 0) Then
MsgBox("轴运动失败!")
End If
' 进行绝对运动
Dim pos As Long
pos = 1000 ' 目标位置
rtn = pci7361_absolute_move(axis, pos)
If (rtn <> 0) Then
MsgBox("轴运动失败!")
End If
' 进行相对运动
Dim deltaPos As Long
deltaPos = 100 ' 相对位移
rtn = pci7361_relative_move(axis, deltaPos)
If (rtn <> 0) Then
MsgBox("轴运动失败!")
End If
' 停止轴运动
rtn = pci7361_stop(axis)
If (rtn <> 0) Then
MsgBox("停止轴运动失败!")
End If
```
以上代码将使用PCI-7361控制卡对一个轴进行原点回归、绝对运动和相对运动,并最终停止轴运动。可以根据需要修改轴号、目标位置和相对位移等参数。需要注意的是,PCI-7361控制卡需要提供正确的硬件连接和驱动程序,才能正常工作。
