Hi

We have a requirement to connect Yokogawa ExaOPC-DA server to ignition server. We are planning to install ignition historian along side our Yokogawa centum vp DCS to improve trends and alarm . Our plant security guidelines suggests to use OPC-UA to communicate. Since yokogawa only supports OPC-DA right now.  
The inductive supplier suggests to install Windows software for wrapper  
OPC DA Client and OPC UA Server. I think this may work for alarms and event listing , but i am not sure if this will also extract trend data... kindly advise.

Thanks

It will only work for the trend data, not the alarms and events. Ignition does not support OPC A&E.
