Trend of Event Frame Attributes in PI Vision
We would like to make the trend of some attributes belonging to the event frames generated for a particular AF Element. For example, we consider the value of the conductivity at the end of the washing phase as an important parameter. We can easily register Event Frames for washing phases and each one with the value of the conductivity at the end, but we would like to put in a PI Vision trend such results for all event frames in a period (referred to the same Unit, i.e. AF Element). As a trend line I imagine an event frame search criteria and an attribute name.
