| description | Methods and apparatus to provide redundancy in a process control system are disclosed. An example method includes receiving, at a first network host, first integrity messages transmitted from a second network host over a first network. The method includes detecting a network failure over a first communication path between a first network interface of the first network host and a second network interface of the second network host via first network when a first network interface of the first network host fails to receive one of the first integrity messages expected from a first network interface of the second network host. The method includes automatically establishing a second communication path between the first network host and the second network host in response to the detected network failure. |
