Makro wyrażenie w opisie event-u

Postby Patryk » Mon 04. Nov 2019 6:46:25

Witam,

Chciałbym mieć możliwość informacji o wartości poprzedniej w opisie eventu jaka była przed zmianą wartości. Więc w PmaData mam utworzoną zmienną i jako rozszerzenie danej w Event->Opis eventu (desc) dodaje makro
wyrażenie w postaci: $.join("Zmieniono wartosc MIN z ",$.expr("Pm.Item("alarm_min").ValueBeforeChange"),"na",$.expr("pDE.Var.Value")). Makro wyrażenie zwraca błąd formuły, która zapewne jest związana z odwołaniem się do "alarm_min".
W jaki poprawny sposób powinienem się odwołać do danej zmiennej? Próbowałem różnych odwołań, lecz dalej jestem z błędem formuły. Dziękuje za pomoc.

Pozdrawiam,
Patryk

Witam,
niech Pan spróbuje w tym makro wyrażeniu zamiast Pm.Item (to odnosi się do "innej zmiennej") zastosować podobny zapis, jak odniesienie do wartości, czyli pDE.Var.ValueBeforeChange.
To powinno zadziałać.

Pozdrawiam
