Just wondering that how to activate PI interface for OPC DA license.
1) First Step, request to check if OPC DA interface is added to your site in my.osisoft.com.
2) Once OPC DA is assigned to the site, download PI license file by uploading machine signature file of PI server.
3) Place the license file in dat folder on PI server and license manager approx take 10-15 min to reflect the change. In general license manager restart is not required.
Note :If you are using PI Collective then rename temporylicense.dat to pilicense.dat and copy to all collective(secondary members).
Once license is applied, always check PI SMT message logs on all PI members for any issues with connectivity or license.
