Abstract
In an industrial automation system, a control device adapted to a container-based architecture has been developed. The control device may comprise one or more containers instantiated with control execution application, communication application, and or redundancy management application.
Claims20
A high availability industrial control automation system comprising:
- a. a set of nodes wherein each node comprises a processor configured with a platform supporting container architecture;
- each node comprising one or more containers instantiated with at least one application function selected from control execution, communication, and redundancy management;
- and
- b. a high availability management network connecting the platforms of the nodes in the set of nodes.
1 more element
A high availability industrial control method comprising:
- a. providing a set of nodes, each node comprising a processor configured with a platform supporting container architecture and each node comprising one or more containers instantiated with at least one application function selected from control execution, communication, and redundancy management, wherein each node is connected to a high availability management network;
- b. detecting a failure state of one or more nodes by communications though the high availability management network;
- c. identifying the containers assigned to the one or more nodes detected in a failure state;
- d. determining available capacity in the remaining nodes by communications though the high availability management network;
- e. redistributing the containers previously assigned to the one or more nodes detected in a failure state to one or more remaining nodes based on the determined available capacity;
- and
- f. automatically starting the redistributed containers.

- b. detecting a failure state of one or more containers by communications though the high availability management network;
- c. identifying the failed container assigned to the one or more nodes and identifying the capacity requirements of the failed container;
- d. determining available capacity in the nodes by communications though the high availability management network;
- e. redistributing the one or more failed containers to one or more nodes based on the determined available capacity and the capacity requirements of the one or more containers;
- and
- f. automatically starting and synchronizing the redistributed one or more containers.
