An industrial automation system employing a mesh topology of input/output allows flexibility in pairing field devices and controllers though the I/O mesh. Field devices can be connected to the geographically closest I/O module channel without regard to the location of the necessary controller. Modular prefabrication and deployment of the I/O modules becomes less complex and less time consuming thereby reducing costs.

I/O mesh architecture for an industrial automation system

An apparatus includes a first distributed control system (DCS) node. The first DCS includes at least one interface configured to communicate, over a network, with a second DCS node. The first DCS node also includes at least one processing device. The processing device is configured to exchange a security association policy with the second DCS node. The processing device is also configured to exchange public keys with the second DCS node using the security association policy. The processing device is also configured to send a public key of the second DCS node to a field programmable gate array of the first DCS node. The processing device is also configured to receive a shared secret from the field programmable gate array. The processing device is also configured to generate a hash of a message using the shared secret.

Embedded security architecture for process control systems

A method includes obtaining current structural information describing a current structure of a process control system and retrieving from a checkpoint file stored structural information describing a previous structure of the process control system. If the current structural information matches the stored structural information, current configuration and operational information of a controller in the process control system is conformed to previous configuration and operational information stored in the checkpoint file.
