networked VI

The following VI runs on a local PC connected to our company network and to an Omron PLC through an additional Ethernet card.

We use OPC server to allow the transfer of data from the PLC to the labview.VI. 

We try to make the VI visible on the network. We use therefore Application Builder to make an executable file loaded then on another PC on the network.

This remote PC could never find the data. As we were being told, we changed the addresses of the data from "opc://localhost/..." to opc://IP address (on the PC running the VI and connected to the PC)/..." without any better success (see the attached VI, the last variable at the bottom of the block diagram)

What are we doing wrong? Thanks for your help

Hi,

There are in LabVIEW DSC a tool called OPC Quick Client. Have you tried connect to OPC server from the remote machine with OPC Quick Client?

I think you problem is DCOM security settings and there are some things that you can do. I recommend you visit the site www.opcti.com to get

articles that help you to configure DCOM.
