Check Xenta Trend Log impact on Vista performance


Trend logs that are stored in a Xenta Programmable must be uploaded to the Vista Server at certain intervals/when certain capacities of memory are reached. If there are many Xenta Trends all trying to upload to the server simultaneously, it can bog down the network and cause communication problems. This utility will help diagnose these situations by providing a summary of all trends and flagging any areas of concern.


  • Vista Server
  • Xenta Programmable controllers
  • Xenta 280, 281, 282, 283, 300, 301, 302, 401, 401:B
  • Xenta Trend Logs


  • Setting a Xenta trend to log values too frequently
  • Setting a Xenta trend to upload at too low of a memory capacity


This utility was created by Benjamin Roswall at Schneider Electric Denmark. It is not an official release, nor is it supported by Schneider Electric. While it has been tested and used successfully, it should be used at your own risk.
