I have an error due to download or upload applications to an V230, anyone can help me? -
Hello! I have problems with downloading the application to one of our V230. Also It doesn't connect with Remote Operator (RO) program. Strange thing is that VisiLogic can do Online Test and then it shows all the online parameters and also remote access can be used during online test. The problem stands in both way, wether I try to download or connect with RO through ethernet or through RS232 (COM1). I was able to download the aplication short time after restart of PLC, but it ended also with some kind of error. Although the PLC seams to work fine and seams that the modified program was downloaded (despite of occured error), I'm not able to download again. I put the pictures of the error messages also here. Does anyone have a clue what can be wrong? Jan -
All, I need to write to a timer preset and am getting an 'object' error using the .net driver. I'm sort of between a rock and a hard place... THanks in advance. Below is the 'function' that attempts to write - Public Function Write_TimerPreset(ByVal tmrIndex As Int16, ByVal TmrValue As integer) As Boolean Dim values As Object() = New Object(2) {} Try values(0) = DirectCast(TmrValue, Object) Catch System.Windows.Forms. MessageBox.Show("One of more of the values are not valid") Return False Exit Function End Try Dim wo As WriteOperands = New WriteOperands() With wo .NumberOfOperands = 1 .OperandType = OperandTypes.TimerPreset .StartAddress = tmrIndex .Values = values .TimerValueFormat = TimerValueFormat.SecondsFormat End With Dim rw(0) As ReadWriteRequest rw(0) = wo Try plc.ReadWrite(rw) Catch Dim ErrorMessage As String = "Could not communicate with the PLC" & vbCrLf & "Error # " & Str(Err.Number) & " was generated by " _ & Err.Source & vbCrLf & Err.Description 'Display the message as a critical message. MsgBox(ErrorMessage, MsgBoxStyle.Critical, "PLC Connection Error") CaptureErr(EquipmentPK, "Unitronics Class", "Write_TimerPreset", Str(Err.Number), Err.Source, Err.Description, Now(), EmployeePK, 0) Return False End Try Return True End Function
