  • Gateway supporting transparent redundancy in process control systems and other systems and related method
    Patent number: 8756412
    Abstract: A method includes synchronizing a first gateway with information from a second gateway. The second gateway operates in a primary role with at least one primary network address. The second gateway communicates with at least one wireless device that uses at least one encryption key during at least one secure communication session. The information includes the at least one encryption key. The method also includes detecting a switchover event at the first gateway. The method further includes, in response to detecting the switchover event, switching the first gateway to the primary role, communicating using the at least one primary network address, and maintaining the at least one secure communication session at the first gateway after the first gateway switches to the primary role.
