Foxboro connection to ignition

Hello,

I am in the process of changing my AB Vantage Point to ignition. But I have a couple Foxboro PLCs that I am currently mapping through PI. How would be the configuration to connect Foxboro directly to ignition? I understand Foxboro lies in a gateway.

But I have no idea the communication path I should be using. Anyone that has integrated Foxboro with ignition?

Thank you!
