1420 Gateway OPC to DeltaV

I am working on intergration between 1420 gateway and DeltaV. I have one wirelessHART Power Meter with 24 auto burst variables reports to 1420 gateway. I would like to feed these 24 varaiable into DeltaV via 1420 gateway OPC protocol.

The problem is how to set up/ configure DeltaV system to pull the data from 1420 gateway? Is anyone done this before? Do I need to set up a OPC server to pull the data from 1420 gateway and feed into DeltaV as a bridge?
