No, it is not clear.

I do not have your ASP file, so I cannot know while line is line 18. It would be best if you post the whole file.

Do you have "On Error Resume Next" before the Client.ReadValue?

And, did the script made it to the "response.write "*** Failure: " & Err.Source & ": " & Err.Description" statement or not? If so, what was the output in the response??

Regards

Hello,

let's do in this way, reset the discussion and start again from the scratch:

Currently at customer site is running a VB6 application/service that is doing many jobs (read/write) with OPCLabs COM
One of them is to reads the following informations (Counters value from current production)

The VB6 instructions is simple as you know:

dim client As New WasyUAClient

ServerOPCUA$ = "opc.tcp://192.168.1.50:4840"
Good$ = "ns=2;s=CurrentJobs.CurrentJob1.Counters.Production.Good"

GoodValue$= Client.ReadValue(ServerOPCUA$, Good$)

the value that you could see in the small windows from VB6 application (NodeId_read.jpg)
then value is written in sql database... etc etc

So now I would like to do the same in ASP to show this values on web page on IIS server

But when I try to read the same NodeId (that is a NodeClass = variable)

Response.Write "Test OPC-UA = " & Client.ReadValue("opc.tcp://192.168.1.50:4840", "ns=2;s=CurrentJobs.CurrentJob1.Counters.Production.Good")
If Err.Number <> 0 Then
response.write "*** Failure: " & Err.Source & ": " & Err.Description
response.write"</BR>"
End If
On Error Goto 0

I got the following error

error '80131600'
/CustomerServer/test-UA.asp, line 18


See pictures in attach (NodeId_OPC-UA_browser.png=, Node Id is equal to "ns=2;s=CurrentJobs.CurrentJob1.Counters.Production.Good" and the value has the same readed out by VB6 application:
value = 3790 pcs

I hope to be clear enough

Please let me have your explanation of the missmatch between VB6 and ASP and in which way I can solve it
Be so kind if I am wrong some where, but is seems so simple
If you need version number , etc etc let me know

Best regards
Alberto

Hello,
I am not sure if I understand your post well. But if I do understand it correctly, then I do not see any problem in the behavior of the UA server or the client.

In one case, you are trying to write into a node that is not writable. And, you get an error that indicates precisely that (BadNotWritable).

In the second case, you are trying to read a value from an OPC UA Object. But Objects do not have a value; only node classes such as Variable do. So, you are getting BadAttributeIdInvalid - precisely what it should do in such case. Perhaps you wanted to choose one of the actual variables *under* the AnalogArray object (on the right pane of the browse windows in your snapshot).

Do you expect some different behavior? If so, why?

Best regards

Hello,

as you suggested I applied err number + err.description management.

Because today the customer is closed and I cannot logon to the remote server, I applied to my local simulation server and to the OPC labs demo server, getting the same error on OPCS Labs demo server
I don't know is is usefull but could be a start to understand a bit more:

In attach you will find the screen of OPC Labs demo server Node Id used to generate error '80131600' (I was lucky to find it) :
Row 67:
Response.Write "Test OPC-UA = " & Client.ReadValue(" opcua.demo-this.com:51211/UA/SampleServer ", "nsu=http://test.org/UA/Data/ ;ns=2;i=11248")
and another generated error on my local simulation server with a well exaustive description of error reason (generated with a write instruction of a NodeId with only read attribute.

Here the asp code used in my test:

Hello.
Please try to obtain more detailed error text. In our VBScript examples under WSH, we use following error handling code, you can learn from that:

' Perform the operation
On Error Resume Next
Dim value: value = Client.ReadValue("http://opcua.demo-this.com:51211/UA/SampleServer", "nsu=http://test.org/UA/Data/;i=10853")
If Err.Number <> 0 Then
    WScript.Echo "*** Failure: " & Err.Source & ": " & Err.Description
    WScript.Quit
End If
On Error Goto 0

Dears,

the idea in background is to realize an asp web page that refresh every minute, showing all the values of the counters of production machines on a monitor
so I started from your sample asp script and did some test, here below the simple code:
<!--$$Header: $-->

<%@ LANGUAGE="VBSCRIPT" %>
<html><head><t-itle>Test-UA.asp</title></head>

	' Instantiate the client object
	Dim Client: Set Client = CreateObject("OpcLabs.EasyOpc.UA.EasyUAClient")
 
       ' Read node value and display it
 
	Response.write "*** Proxsys simulation server MILNB011 (my developing laptop)  ***"
	response.write "</BR>"
	Response.Write "job order= " & Client.ReadValue("opc.tcp://MILNB011:53530/OPCUA/SimulationServer", "ns=3;i=1011")
	response.write "</BR>"
	Response.Write "production counter = " & Client.ReadValue("opc.tcp://MILNB011:53530/OPCUA/SimulationServer", "ns=3;i=1009")
	response.write"</BR>"
 
	Response.write "*** http://opcua.demo-this.com:51211/UA/SampleServer ***"
	response.write "</BR>"
	Response.Write "Test OPC-UA = " & Client.ReadValue("http://opcua.demo-this.com:51211/UA/SampleServer", "nsu=http://test.org/UA/Data/;i=10845")
	response.write "</BR>"
	Response.Write "Test OPC-UA = " & Client.ReadValue("http://opcua.demo-this.com:51211/UA/SampleServer", "nsu=http://opcfoundation.org/UA/Boiler//Instance ;ns=5;i=40")
	response.write "</BR>"
	%>

everything is working fine, as should be.

But i try with the following row, at customer site server
Response.Write "Test OPC-UA = " & Client.ReadValue("opc.tcp://192.168.1.50:4840", "ns=2;s=CurrentJobs.CurrentJob1.Counters.Production.Good")
I got the following error

error '80131600'
/CustomerServer/test-UA.asp, line 18

where line 18 is exactly the above istruction row

The main difference is that NodeID is in the following format "ns=2;s=CurrentJobs.CurrentJob1.Part.PartName" in the not working row (real environment)
instead of NodeID "ns=3;i=1011" in the working row (simulated environment)

Thanks for any suggestion you could provide.

BR
Alberto
