1.请问PLC中VB代表什么意思?
2.从plc读取得实数怎样在vb的编写编程text中显示为浮点数,怎样生成安装文件
3.谁有VB和OMRON PLC 通信例子啊?能否发个原始代码? 再次特别感谢!密源码
请问PLC中VB代表什么意思?
您提供的编写编程是一个关于PLC(可编程逻辑控制器)的等式和变量赋值问题。根据您提供的密源码等式和变量赋值,我们可以逐步计算出其他变量的编写编程显卡hdmi音频源码值:给定条件:
V3.5 = 1
V1.0 = 1
VB2 =
VB = 5
我们要计算的变量:
V0.1
V2.3
VW0
VB1
VB3
VW2
VD0
根据给定条件和一些基本推理,我们可以逐步计算出这些变量的密源码android兼职app源码值:
V0.1 = V1.0 + VB = 1 + 5 = 6
V2.3 = V3.5 + VB2 = 1 + =
VW0 = V3.5 = 1
VB1 = VB2 + VB = + 5 =
VB3 = V3.5 + VB1 = 1 + =
VW2 = V2.3 + VB2 = + =
VD0 的值在您提供的等式中没有给出,因此无法计算。编写编程
综上所述,密源码根据给定条件,编写编程变量的密源码值为:
V0.1 = 6
V2.3 =
VW0 = 1
VB1 =
VB3 =
VW2 =
请注意,以上计算基于您提供的编写编程等式和赋值,如果有其他背景信息或等式,密源码请提供更多详细信息以获取准确的编写编程自建外卖平台源码计算结果。
从plc读取得实数怎样在vb的密源码text中显示为浮点数,怎样生成安装文件
第一个问题,编写编程你直接取PLC里的标签值就可以了,不知道你用的项目管理源码大全是什么PLC,通过OPC
server可以很方便取出数据,注意下类型就可以了,在西门子系列中,用的期货多头指标源码是B,方式譬如
s7
[s7:connection_1]数据模块,B标签地址
第二个问题:
由于VB需要用到VB自带的库文件,所以需要打包,生成exe文件之后,
1.
选择菜单项中的
外接程序,选择外接程序管理器
2.
选中Package
and
Deployment
Wizard,在
加载行为里,选择
加载/卸载,然后点击确定
3.
再次选择菜单项中的
外接程序,这时可以看到里面有Package
and
Deployment
Wizard这个选项了,点击它,选择弹出窗体中的第一个就是Package就OK了,然后基本都是下一步
谁有VB和OMRON PLC 通信例子啊?能否发个原始代码? 再次特别感谢!
提供一个VB.NET与OMRON以太网通讯的代码,是我项目里面复制出来的: Dim Handle1 As Int 'PLC的连接句柄Dim EntLink As Boolean '连接标志
Dim PLC As New FinsTcp.PlcClient '引用OMRON的通讯组件
Private Sub butLink_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles butLink.Click
Dim re As Short
Dim restr As String = ""
re = PLC.EntLink(Trim(txtLocalIP.Text), Val(txtLocalPort.Text), Trim(txtRemoteIP.Text), Val(txtRemotePort.Text), "DEMO", Handle1)
txtReLink.Text = re.ToString
If re = 0 Then
EntLink = True
MsgBox("PLC联接成功! ")
Else
EntLink = False
MsgBox("PLC联接失败: " & restr)
End If
End Sub
Private Sub butClose_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles butClose.Click
Dim re As Short
EntLink = False
re = PLC.DeLink(Handle1)
txtReClose.Text = re.ToString
End Sub
Private Sub butRead_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles butRead.Click
Dim re As Short
Dim i As Short
Dim RD() As Object
ReDim RD(Val(txtReadCnt.Text - 1))
If Not EntLink Then
MsgBox("还未与PLC建立联接!")
Exit Sub
End If
Dim mry As FinsTcp.PlcClient.PlcMemory = cmbReadMry.SelectedIndex + 1
Dim typ As FinsTcp.PlcClient.DataType = cmbReadType.SelectedIndex + 1
re = PLC.CmdRead(Handle1, mry, typ, CUShort(Val(txtReadAdd.Text)), CUShort(Val(txtReadCnt.Text)), RD)
txtReRead.Text = re.ToString
lstRead.Items.Clear()
For i = 0 To UBound(RD) Step 1
If Not IsNothing(RD(i)) Then lstRead.Items.Add(RD(i))
Next i
If re <> 0 Then
Timer1.Enabled = False
butScan.Text = "Cycle R/W"
End If
End Sub
Private Sub butWrite_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles butWrite.Click
Dim re As Short
Dim i As Short
Dim temp() As String
Dim WD() As Object
If Not EntLink Then
MsgBox("还未与PLC建立联接!")
Exit Sub
End If
ReDim WD(Val(txtWriteCnt.Text) - 1)
temp = Split(txtWrite.Text, vbCrLf)
For i = 0 To UBound(WD) Step 1
If i > UBound(temp) Then
WD(i) = 0
Else
WD(i) = Trim(temp(i))
End If
Next i
Dim mry As FinsTcp.PlcClient.PlcMemory = cmbWriteMry.SelectedIndex + 1
Dim typ As FinsTcp.PlcClient.DataType = cmbWriteType.SelectedIndex + 1
re = PLC.CmdWrite(Handle1, mry, typ, CUShort(Val(txtWriteAdd.Text)), CUShort(Val(txtWriteCnt.Text)), WD)
txtReWrite.Text = re.ToString
If re <> 0 Then
Timer1.Enabled = False
butScan.Text = "Cycle R/W"
End If
