Event on a item doesn't work..
with the Single Developer + Runtime Free license, you get a single .BIN file that is both for development purposes (by one developer) and runtime deployments.
Best regards

Just to be clear: We have 1 bin file and can use this with the licence maganager on both the Development Machine and the Production PC's?

And, below is the part that describes installing the license:
3.7 License Manager
The License Manager is a utility that allows you to install, view and uninstall licenses.
In order to install a license, invoke the License Manager application (from the Start menu), select “QuickOPC 5.3” in the component drop-down, and press the Install license button. Then, point the standard Open File dialog to the license file (with .BIN) extension provided to you by your vendor.
Note: You need administrative elevated privileges to successfully install and uninstall licenses.
(in Windows 8 and later, you may have to look for the License manager alphabetically, or use the "Search" facility to locate the License Manager in the "Start Menu")

I'm using your object in Access 2010.
I try to catch a event but he doesn't enter the function. Here is the code I use now:
Dim MonitoredItemArguments1 As EasyUAMonitoredItemArguments
Set MonitoredItemArguments1 = CreateObject("OpcLabs.EasyOpc.UA.OperationModel.EasyUAMonitoredItemArguments")
MonitoredItemArguments1.EndpointDescriptor.UrlString = "opc.tcp://STP-OPC-01.domain1.local:55101?None?opcfoundation.org/UA/SecurityPolicy#None"
MonitoredItemArguments1.NodeDescriptor.NodeId.ExpandedText = "ns=3;s=s7400.db500.16,r"
Set MonitoredItemArguments1.MonitoringParameters = MonitoringParameters
MonitoredItemArguments1.State = "D2"
Dim arguments(0)
Set arguments(0) = MonitoredItemArguments1
' Subscribe to OPC monitored items
Call client.SubscribeMultipleMonitoredItems(arguments)
Call client.WriteValue("opc.tcp://STP-OPC-01.domain1.local:55101?None?opcfoundation.org/UA/SecurityPolicy#None", "ns=3;s=s7400.db500.16,r", 4) 'Real here I set a new value
Private Sub Client_MonitoredItemChanged(ByVal Sender As Variant, ByVal E As OpcLabs_EasyOpcUA.EasyUAMonitoredItemChangedEventArgs)
' Schedule an update. The cell name is passed to us in the State property.
Dim str As String
str = "" ' doesn't enter the breakpoint here.
' ValueString = """" & Replace(Replace(E.AttributeData.Value, """", """"""), "'", "''") & """"
' Application.OnTime Now, "'Sheet1.UpdateCell """ & E.Arguments.State & """, " & ValueString & "'"
End Sub
I also get a error on this line:
MonitoredItemArguments1.State = "D2"
Error: Object Required.
When you can resolve this for me I will be able to use this in production and buy the control.
Thanks!
