Tags ->PItoPI

Discussion created by marco.zoccoli on May 8, 2014



we have a problem with the timestamp of some tags connected to a PItoPI interface.


We need to configure some tags on PI Concentrator such as they show the same values and TimeStamps of the PI Source.


On PI Source,

  1. some of the tags (to be configured) are acquired (exception and compression enabled) and they have same value&timestamp on PI Source and PI Concentrator
  2. some others are Calculated (exception and compression enabled) and sometimes there is a misalignment between the timestamp on PI Source and timestamp on PI Concentrator ->KO

Is the issue due to the exception and compression enabled on PI Concentrator? Should I take into account some other parameters?
