The sequence is relevant for formulas executed at the same evaluation point. For example, formulas 1, 2 and 3 presented in the following figure are processed before sending message /CAN0/CanEasy/Datapacket in exactly this sequence. Formulas can be sorted using drag & drop editing.
The Checkboxes in the column “Active” specify if the formula is evaluated when the evaluation point and the dependency are met. By unchecking this box (entry no. 4 in the figure), formulas can be excluded from evaluation without having to remove the expression or the complete formula. The columns “Evaluation event” and “Dependency”, are explained in the chapter formula editor.
From the context menu, formulas can be added, edited or deleted.
If formulas become invalid due to incorrect, deleted or changed signals/messages, they are highlighted and identified by a warning triangle symbol.
