I have multiple windows with components that need to reference the value of a single gateway tag via indirect tag references. Does Ignition recognize this (and retrieve it only once from the gateway when the value changes) or does each binding incorporate its own overhead in retrieving a separate copy of the value from the gateway?
Would it be more efficient to link a client tag to the gateway tag and have the window components bound to the client tag? One benefit that I can see is that it would reduce the number of indirect tag bindings that one has to configure (or update in the future if needed).
Thank you for the response pturmel but your answer doesnât address my questions. Maybe I didnât phrase my questions clearly. I am not trying to determine whether Ignition is doing it right or wrong. There are usually several ways to handle a particular operation in Ignition and Iâm simply trying to determine which would be the most efficient in this case. My application uses Ignition Edge on a standalone controller so there is not an infinite amount of resources available (as compared to a server). It may not even matter from an efficiency perspective, but I would rather ask the question up front rather than risk running into issues down the line after the project structure has been solidified.
And, regarding whether a client tag is âmore efficientâ - no, not really, although it does, as you pointed out, potentially reduce future maintenance burden, which is its own selling point.
