Abstract: A method and systems for a redundant server automatic fail-over system is provided. The system includes a plurality of client devices communicatively coupled to a network wherein the plurality of client devices each includes an active server identification location. The system also includes a first server system communicatively coupled to the network that is configured to operate as the active server on the network wherein messages sent to the first server system are addressed to the first server system using the active server identification location on each client device. The system further includes a second server system communicatively coupled to the network that is configured to operate as a standby server on the network and is configured to switch to being the active server on the network when it is determined that the first server system is unable to operate as the active server.

Abstract: A method for synchronization of data stored in redundant servers of a process control system is described. The redundant servers include an active server and at least one standby server, in communication with a plurality of applications. The method includes generating a memory snapshot of information stored in a plurality of active server memory locations at a predetermined time. The information stored in the plurality of active server memory locations includes application operating data for the plurality of applications and the memory snapshot includes a data structure that includes a copy of the information stored in the plurality of active server memory locations. The method also includes transmitting the memory snapshot from the active server to the at least one standby server, and storing the memory snapshot at the at least one standby server.
