Kepserverex Failed To Create File Install The OPC

If you cant browse with a commercial client you can be sure that there are issues with the server or with Windows configuration.

It basically says that you are free to redistribute the binaries.

If you copied and pasted my code you should check why writeValues array is null (not initialized).

I mean that before this line: writeValues0.ServerHandle group.Items0.ServerHandle; you must have somewhere a code like: List valueList new List (); initialize the List ItemValue itemValue new ItemValue(itemToWrite); initialize the item at index 0 valueList.Add(itemValue); add the item.

Is it an error on this line writeValues0.ServerHandle group.Items0.ServerHandle; Because this line is needed only when you write to your items.

Also did you test the OPC Server with a Test client Could you read your items with the OPC test client provided by your OPC Server.

But I am not trying to write,I am trying to read the data from opc server.

But, even after configuring the aliases and items in the opc server, I am unable to read any data.Kindly help me regarding this.

If you can browse the OPC server through the OPC Test Client and you can read the values, i can check and correct your code, but i will post it corrected in this site so it will be useful for all people.

If you think that the problem is in the code that you wrote, just mail me to solution at michelecatta at gmail dot com.

To solve the problem, please uninstall the OPC core components (if they are already installed) and then reinstall them.

I mean a connection string made like this: server.Url new Opc.URL(opcda:192.168.0.10RSLinx OPC Server); instead of server.Url new Opc.URL(opcda:localhostRSLinx OPC Server).

For what i know, its needed only the IP of the remote PC to connect to a remote OPC Server; you should also configure the DCOM settings on both PC and configure both firewalls.

Again, if there is a port to be open, is the OPC Server vendor that should tell you what port it is.

To check the DCOM settings run a search on google on how to configure DCOM for remote OPC server.

When you are able to browse the remote OPC server from your test client, you can try to connect to the server using my example.

An easier way to connect to a remote OPC server is using an OPC Xml client, but i dont have any example at the moment.

Check if this post helps you, or try to google the error for an answer.

Have you ever tried Because, I heard that OPC Da is not allowed to access by the Internet (DCOM constraints).

The configuration is far from easy, but both OPC foundations forum and Microsofts papers can help you with this.

I suggest you to test the connettivity with an OPC Test client, better if it comes from your vendor.

Once you could access to your server through internet, you can start develop your own client.

Googling for it shows that can be caused by a bad installation (so you should try to stop the service with regsvr32 u name of BR dll; repair or reinstall the OPC server then restart the service with regsvr32 name of BR dll).

I think that you should contact BR anyway, because the support is free for their products, and you can ask them why a common OPC DA client doesnt work.

Another test that you should do is also to browse the OPC server through an OPC Test Client from the PC that you are using the application (like in this article ).
