Abstract
Aspects of the invention provide apparatuses, systems, and computer readable media for supporting redundant network management. When the primary device () fails, its Ethernet IP address is transferred or controlled by a backup Ethernet device. System information is provided to a network adapter so that programmable logic controllers are in agreement about the mode of operation. A central processing unit () determines a calculated mode of operation from the operational statuses of the programmable logic controller and the mated programmable logic controller. The central processing unit provides an address indication () based on the calculated mode of operation and a selection indication () that is indicative of a selected address criterion. The corresponding network adapter determines the assigned network address from the selection indication and the address indication.
