Can RR communicate through an OPC bridge ?

A customer has a vision system using Ni Vision builder. This communicates variables via an OPC bridge to a GUI written(compiled) in Delphi. This is fixed and the vendor has vacated.

I'm thinking of installing RR to develop an alternative GUI. The camera is a Point Grey device to a PCI card using firewire, so I can't mess with that.

I see OPC and UDP comes up blank in the forum..

That looks like something we can incorporate. Give us some time to review that spec and I'll post an update here probably sometime next week.

Does the image get communication over OPC or is that something you'd communicate with via the PCI card?

Does the Delphi GUI implement an OPC server or client? I.e. what side do you need in RR? The client is a lot simpler to create whereas the server will take a while longer.

Hi STeven

I have not been able to explore the system in depth yet. It's mostly in use and I can't play with it much. I'll need to build a picture of all the programs running and see what was written and what is commercial.

It's a long term project and I'll probably only get into it in depth in November, when I can give you better info and more direct questions.
