I am attempting to have a permissive to start a sequence that requires a temperature PV stay within 10 Deg C of itself for the last minute.
Is there a way to constantly write a value 60 seconds in the past to an intermediate tag which can then be used to compare the present value? I'm thinking this would require moving 60 seconds worth of values into something like a FIFO register?
Any help from someone who has done this before would be greatly appreciated.
