Initial Value


List of Group Membrs




Contains the references (Input References) that define the members of the group. These group members are referenced during a transaction. The list of group members consists of two parts:

  • Object ID

  • Element

All members of the group are objects that reside in the same device that maintains the Group object. Nesting is not allowed. This attribute is only shown in the Snapshot view.

Present Value


Lists the values of all the attributes specified in the List of Group Members. This is a read-only attribute; it cannot be used to write a set of values to the members of the group. The Present Value list reconstructs each time the attribute is read by fetching the member attributes. This attribute is only shown in the Snapshot view.
