Embodiment Construction

[0015] Discussed below Figure 1 to 4 The various embodiments used to describe the principles of the present invention in this patent document are merely illustrative, and should not be construed as limiting the scope of the present invention in any way. Those skilled in the art will understand that the principles of the present invention can be implemented in any type of suitably arranged device or system.

[0016] figure 1 Illustrated is an example industrial process control and automation system 100 according to the present disclosure. Such as figure 1 As shown in, the system 100 includes various components that facilitate the production or processing of at least one product or other material. For example, the system 100 is used here to facilitate the control of components in one or more factories 101a-101n. Each plant 101a-101n represents one or more processing facilities (or one or more parts thereof), such as one or more manufacturing facilities for producing at least one...

Abstract

A method includes establishing (408), using a connection policy at a first device (202, 204, 302, 304, 306), a security association with a second device (202, 204, 302, 304, 306) of an industrial process control and automation system (100). The method also includes, once the security association is established, activating a process data policy at the first device. The security association is established during first and second types of negotiations (406). The process data policy is activated during the second type of negotiation (412) without the first type of negotiation. The second type of negotiation is faster than the first type of negotiation. The connection policy defines a communication channel between the devices using a non-process communication port of the first device. The process data policy defines a communication channel between the devices for real-time industrial process data. The first type of negotiation could include an IKE main mode negotiation, and the second type of negotiation could include an IKE quick mode negotiation.

Description

[0001] Cross-reference and priority statement of related applications [0002] This application claims the priority of U.S. Provisional Patent Application No. 61 / 943,806 filed on February 24, 2014 in accordance with Section 119(e) of Section 35 of the United States Code. This provisional patent application is hereby incorporated by reference in its entirety. Technical field [0003] The present disclosure generally relates to industrial control and automation systems. More specifically, the present disclosure relates to devices and methods for establishing seamless and secure communication between components in industrial control and automation systems. Background technique [0004] Industrial process control and automation systems are often used to automate large and complex industrial processes. These types of systems conventionally include various components such as servers, clients, sensors, transmitters, and field devices, which are used to control and automate entire industr...
