Connecting to remote HDA Server

Hello folks,

We are trying to connect an Ignition Gateway (8.0.10) to a remote OPC-HDA server (Proficy Historian).

I know it can works. But you know… DCOM nightmare.

Could I install a local gatewayon the historian server and connect locally using the OPC-HDA module then create a remote tag connection between the “main” gateway and this “secondary” gateway to have access to the tags in the proficy historian?

Thanks

We’ve run into the same issue with a one of our customers, but for an OPC-DA server. We ended up taking the same approach that you’re suggesting and it has worked out quite well.

We finally have been able to create the connection trought the DCOM object. So we did not have to install a local gateway on the Historian machine.

Now our problem is we cannot see any data . We can browse the tags that are in GE historian, but when we drag one thge tags on an easy chart, no data is displayed.

Any ideas?
