Folks, We have a PI system where PI Data archive and PI AF Application and Notifications installed on three different servers. Based on solution requirement we need to read data directly from multiple plant pi servers to perform AF analytics/Notifications. We have established trust between PI AF server and Plant Pi servers which works fine. Notification rules are to be configured based on event frame generation(analysis output). My questions is , notifications to work properly does PI notification service needs read access to individual Plant PI data archives. I believe since PI AF has read access the plant pi data archives, it may not be needed. Kindly clarify how it works.
