Title
(EN) Method and apparatus for network variable aliasing
Abstract
(EN)

A method and apparatus for resolving connection conflicts in a network is provide. A network connection point on a node cannot be added to a first network connection when it already belongs to a second network connection. When a particular configuration would otherwise violate this rule, a network connection point on the node is established as an alias to the network connection point. The alias network connection point is added to the first network connection. A correlation is established between the alias network connection point and the network variable that is associated with the network connection point. If the network variable is an input network variable, then the value of the network variable is updated responsive to messages received on either the first or the second connection. If the network variable is an output network variable, then messages are sent over both the first and second connections when the network variable is updated. The correlation between the alias network connection point and the network variable may be established through tables in the apparatus, or through the use of an alias variable defined in the same application as the network variable.
