Node-Red using Node OPC UA communication to access services from 61499

Hey Guys,
I have a control application in IEC 61499, which controls a Node.js process simulator using OPC UA.
Now, I am trying to connect Node-Red using Node OPC UA communication to access services from 61499.
In Brief: 61499 Function blocks exposing functionality as OPC UA services (control of valve, pump, etc.) and accessed through OPC UA Client implemented in Node-Red.

Some helpful ideas will be really appreciated.

Thanks.
Br,
Shaan
