I'd like to use a reference with a variable in a trigger of an event frame..
But i'm not able to convert the string to a valid reference of a tag.
Exemple : the trigger i'd like to have is : '.\OA01|OA__Bal_Alim_al_Vit'=1
Value type of OA__Bal_Alim_al_Vit = double
But i want to use a variable to define the number 1 of "OA01".
Actually, i put this formula in a variable of the event frame.
Element = Concat("'.\OA0",Mid('CODE_TAG_BODY',6,1),"|OA__Bal_Alim_al_Vit'")
The result of Mid('CODE_TAG_BODY',6,1) is 1 or 2 or 3...depend of the element.
Start trigger :
Element = 1
It doesn't work.
is there a formula for converting a string to a tag reference ?
