But when I try to connect to another computer \\Anod\\RSLinxOPCServer\TopicName\Something[0] I have info: "Access Denied!". How can I resolve the problem?

Thanks.

Yes. And I have the same problem with excel when I am trying to connect by DDE. Access Denied! In excel when I write =rslinx|topicname!itname then everything is working good. But when I try =\\hostname\rslinx|topicname!itname then no connection. Meaby something wrong with network settings but witch one?

Exacly message is:
"Error: Can't connect to OPC Server.  Registry access denied."

When I am trying to connect by LabWindows OPCClient.

Hi prepond,

I'm not expert in how to work with this OPC server, but it looks like problem in permissions settings. You can have a look at "RSLinx VB Remote OPC" for some inspiration where the problem could be (I know, it is about VB, but in general, this kind of problems should not be language dependent). You might check if DCOM is set correctly (you can find some informations in "Using OPC via DCOM", page 6). Maybe you can find some information about access violation in Windows event viewer, and you can then set proper group or user permissions.

Regards,

Martin
