I would like to add a device to the gateway -OPC UA. I am trying to add a red lion HMI to access the tag data. I am not sure how to set it up. It was recommended to use modbus tcp. The HMI has an IP that is reachable. sample tags image attached

Hi Dan,

You are correct that it is recommended to use Modbus TCP. Here is a link from our user manual that goes through how to connect. [Connecting to Modbus Device](https://docs.inductiveautomation.com/display/DOC81/Connecting+to+Modbus+Device)

There is also a nifty Inductive University video to supplement the information in that linked document on the right side.
