OPC Client Problem

[mimran]

Hi

I am having problem in configuring opc client. The way I configure OPC Client is given below

Create a New Project

Creat a New OPC Client I/O Server.

Select the appropriate server from the list.

OPC Server will be created.

Right click on OPC Server and select Deploy all.

Right click and then select create bound variables.

I have tried this procedure but no success. Once I managed to view the Tag names of Channels present on the server but values were never transported to opc client from the server.

I have also tried distributed System Managment for the removal of variables before creating any new opc server.

Moreover OPC QuickClient works perfect which shows that OPC Server is right. So now there are some settings in Labview. PLease help me out in solving this problem. Have a look in the attachment picture.

Thanks

Is the OPC Server on local computer?

You can configure a diagnostic log file in OPC Client's property. Deploy the library and a opc communication log file will be created. post the log file here.

I also suggest you to post your problem in LabVIEW forum.

There are some errors when validating items. It's not sure if the problem is in DSC or OPC Server.

Do you know where I can download the OPC Server? It's good to have an evaluation server.

Hi Ryan,

I am using OPC server of Third Party and treating Labview as an OPC Client. NI OPC Server works OK on my system .But that third party server has given me those errors.

Thanks

I tried to get something more from the log file, but it just tells me the errors. I cannot figure out which one has the problem, DSC or OPC Server, and why.

It looks like a problem in OPC Server. DSC gets the data ID from OPC Server, and immediately use this data ID to validate and got the data ID syntax error.

So I want to know if the OPC Server has an evaluation version that I can test with DSC on my computer. I can also use the OPC test tool from OPC foundation to test the OPC Server. What's the name of the OPC Server?

Hi Ryan,

That OPC server is dongle protected having no evaluation version. I have attaced a picture in this reply running OPC Free Client in background AND LABVIEW running at front. You will notice that Free OPC Client  shows good signal quality and Labview showing error.

OPC Free client is shiped by NI.
