    Default Activate variables based on new structure elements

    Hello,

    we are working with structures which are imported from the PLC programming software. When we are updating this structures there are some new entries. When we have some variables which are based on this structures the new entries are inactive.

    In the editor it is possible to go to the new entry with right mouse button and select "Activate all variables based on that".

    But I want to do this in VBA, because there I know which entry is new!

    Is there a possibility?

    regards
    Wolfgang

    Default AW: Activate variables based on new structure elements

    You can do this with the method of the variable object called "ActivateSubItem"
    -> check out the help documentation of the programming interface at
    -> Object model -> Variable -> ActivateSubItem

    So if you have new entries in the datatype structure you need to loop through all variables, check if the variable bases on the new entry of the datatype structure (SubItem) - if so activate the variable with the above mentioned method.

    Doing this via the zenon Editor (with option "Activate all variables based on that") the same algorithm is used.

    regards,
    Herbert
