Connection with OPC client

Hi,

I would like to access to my shared variables using an OPC client. (a free software called powerOPC or any other one)

When I use it locally, everything goes well, I can access my shared variables, but when I try to access from a distantr PC, I cannot connect and get some errors. I've tried to open port 135 on the firewall, I've read the following post: http://forums.ni.com/t5/LabVIEW/opc-dcom-access-denied/m-p/822246/highlight/true#M373884

But I still can't access my variables.

The NI Distributed System Manager can access to the distant shared variables, so I don't know what's wrong with other clients.

Does anyone knows how to do?

 

Both PC are running win 7, one is 32 the other 64bit.

Hi toto26,

 

thank you for using National Instruments discussion forum.

 

Could you detail the way you use to communicate with your OPC server thanks share variable? Are you using datasocket like in this document or are you using DSC ?

 

Could you tell us more about the errors you get? Have you already seen this KB document and its first related link?

 

Thank you in advance

Regards,
