     If the variable on the other side of the \lstinline!connect!-equation is \lstinline!input! or \lstinline!output! the new component will be either \lstinline!input! or \lstinline!output! to satisfy the restrictions in \cref{restrictions-of-connections-and-connectors} for a non-expandable connector.

     The general rule ensures consistency for inside and outside connectors, and handles multiple connections to the new component.

+    For the simple case of no other connections involving these variables it can be explained as follows.
     If the existing side refers to an inside connector (i.e.\ a connector of a component) the new variable will copy its causality, i.e.\ \lstinline!input! if \lstinline!input! and \lstinline!output! if \lstinline!output!, since the expandable connector must be an outside connector.
     \end{nonnormative}
     For an array the \lstinline!input!/\lstinline!output! property can be deduced separately for each array element.
