      Hi Osi Team,

       

      I want to ask something about our PI Vision, after we updated PI Vision to R2 SP 1 we got communication error notification in PI Vision Display.

      All of the display was disappeared, what should we do? we hope all of file (.piw or .svg or other) could appear in PI Vision display.

      before updated, we have a problem that all image can't appear if the file format is .PIW. if format .svg image appear. so we update the version.

       

      Thank you for your response.

       

      Best Regard,

      Dede

          Hi Dede

           

          Communication error is related to "AF attribute or PI point" unable to get data from PI server with in the time interval. In some cases it is specific to IIS (Web Server) communication to PI system. If worker process is idle without any action you generally see "Communication error". REquest you to check communication from PI Vision server and more especially logs on PI vision server and event viewer.

           

          In SMT request you to check w3wp.exe in the message logs to understand in case of any issues with PI server connectivity during the time period.

           

          Thanks
