Hello, I work with HVAC data and am trying to find an efficient way to model my buildings in PI.    The challenge I have is that I'd like to use templates but there are slight differences or features that some units have and others do not. For example, we have 300 Air Handlers and there are probably about 40 different configurations of those… (Show more)

Hi, I'm calculating the efficiency of a hydro block using Outlet flowrate/ Inlet flowrate. However this hydroblock is not running 24 hours, the efficiency returns 0 if it is not running. If I wana plot a trend of the efficiency against last 300 days in PI Vision, this 0 value will be disturbing. So I'm looking for an expression or formula to… (Show more)

Does anyone have experience exporting event frames from a previous version of AF Server and Importing them into the newest version?.   I find myself needing to perform this task and I'm trying to get ahead of possible compatibility issues.

Hello PI world,   I am interested in the specifics of event frame security.   Where does an event frame inherit its security settings from? Is it from the element that it is referenced to? Is it from the event frame template? I thought the security of the template relates to user access to modify that template. Are there different settings to… (Show more)

Is it possible to configure Indirect References in a PI Point Array Data Reference? The documentation clearly defines how to configure an Indirect Reference (that is, an explicit or relative attribute path) for a (non-array) PI Point Data Reference. The documentation seems to imply that this is not possible for PI Point Array Data References,… (Show more)
