  1. That's exactly what I am trying to do, but I am afraid it's not possibly as you say. I have already tried to create different reference profiles and splice them together in a single formula. It works, so for now I guess I will have to do that. It will be just a matter of keeping everything organized when creating that large amount of signals. Thank you so much Andrew!
  2. Thank you so much for your answer. What you mention about creating a reference profile and then splicing the different reference signals together is the way I found suitable to do it. The thing is that I would need 2 reference signals for each variable (pressure and temperature), and that multiplied by the different grades make quite a lot of signals per Reactor. I wanted to avoid creating too many signals, but apparently that may be the only solution. Regarding the "splice" os conditions, the issue I found is that I do not manage to found a way to do the next logic: If Grade = A; { ReferenceTime = AAAA //Reference Time for grade A ; if Grade = B; { ReferenceTime =BBBB //Reference Time for grade B ; else Reference Time =CCCC //Reference Time for grade C }} Something Like that (not an expert in programming as you see 🙂 ). The option that you mention are useful to identify the capsules and manipulate them, but not to chose between already identified capsules. Again, thank you so much!
  3. Hi! I am trying to create a formula which accounts for different reference times depending on the product to be produced. It would be like the Splice function, but for conditions instead of signals or scalars. My objective is to create a pressure reference profile which is modified depending on the product which is produced. For this matter, I need: - A formula with different reference capsules (input condition in the reference profile tool). - A formula with different conditions depending on the product ((Apply to condition in the reference profile tool). What I would like to do (if it was possible), would be the next: condition(capsule("2021-06-27T07:15+02:00", "2021-06-28T10:50+02:00" .splice(condition(capsule("2021-06-27T07:15+02:00", "2021-06-28T10:50+02:00")),$GradeA) .splice(condition(capsule("2021-06-27T07:15+02:00", "2021-06-28T10:50+02:00")),$GradeB) .splice(condition(capsule("2021-06-27T07:15+02:00", "2021-06-28T10:50+02:00")),$GradeC)
