Fernhill Connection Using OPC UA for Two AB PLCs (Master and Slave)

Hi All,

Has anyone had the experience of connecting two Fernhill Scada units using an OPC UA? 

I am intending to use Fernhill Scada on my Master PLC to read tags from my Slave PLC's Fernhill Scada. Then, displaying local tags (Master PLC, "Fernhill SCADA Unit 1") and read/scanned tags from the Slave PLC, "Fernhill SCADA Unit 2".

In the meantime, I am trying to use both of my Fernhill SCADA units interact with each other (one unit to read tags from the other unit) by using Internal Digital Tag on the Fernhill SCADAs. 

Any help would be appreciated.
