I don't know of anyone using AIM*OPC HDA Server, but it was created to do what you are proposing.

While we are discussing this matter... What is your opinion for having OPC-HDA setup ? i.e.: PI API for OPC <- AIM*OPC HDA Server <- AIM*API <- OM API > Are you aware of anyone using OPC-HAD for PI (or any other plant historian) ? > If so, what is the experience so far ? > Any tips/tricks ?

Why? Simple - fewer layers of code are better. PI API for OPC <- AIM*OPC DA Server <- AIM*API <- OM API Or PI API for OPC <- FoxAPI <- OM API Fewer things to go wrong.

Sent: Thursday, April 26, 2012 2:16 PM To: Foxboro DCS Mail List Subject: [foxboro] OPC or API on Windows box and AIM Historian We will be upgrading our historian sometime in the next year to three years. Are there advantages to using OPC rather than the API to the beloved PI historian? Or are there nightmares waiting to make some bad days and nights. Just curious before any jump is made. Or this may be the Ford, Chevy, or Dodge discussion.
