We need to connect Ignition to a Pi server using OPC-HDA.
I have 2 redundant gateways (8.1.3).
How would you proceed?
1- Install the Pi OPC-HDA bridge on both Ignition server. No need to configure DCOM since the OPC-HDA server and client are on the same machine. Simpler but need to install OPC-HDA twice.
2- Install the OPC-HDA bridge on a dedicated VM and connect both Ignition’s gateway on it.
