Wonderware Siemens

[Athina Dollison]

Whywould you put the wonderware historian in the middle?

Just point at the OPC items that the historian is collecting instead and send those out.

Unless you are looking to do aggregates from history, then you could always create a database connection pointed at the Runtime database on the wonderware historian and execute queries against the datasource.

wonderware has several stored procedures you can use to query history data.

So not overly familiar with Wonderware historian (2012) so your saying the historian links between intouch and the historian using OPC??. I assume the is OPC DA? So how do I point Ignition edge at the OPC DA server when Iginition Edge looks like it only support UA.
