Is it possible to dynamically change PI point attributes based on events

point attributes eg

compdev , exdev , compressing

 

For some processes there are times (event frames) when you would like to collect as much data as possible for a tag

(smallest resolution , no compression or (basically) all values from the source system) , while outside those times you only need to collect data at an increased resolution and with compression.

 

 

Example : for a sterilization process, I want all the values of the temperature (+/- 0.1 deg  , no compression) during the sterilization phase , however out side of that phase (heating , cooling , not in use)  I just want to have a rough idea of the temp  (+/- 1deg , compressed)
