Abstract

A controller and module for an industrial automation system is provided. A logical module employs resources and logic to expose functionality of the module while providing generic interfaces to external components of the module. A controller is operable with the logical module to provide interactions with components that are at, above, or below a layer associated with the controller.

Claims

1. An industrial automation system, comprising:

a plurality of modules, comprising;

at least one equipment resource control module, comprising;

a common interface that includes one or more attributes and input/output capabilities that are standard among the plurality of modules; and

logic of a first platform that controls a state of at least one equipment resource in the industrial automation system;

at least one material resource control module, comprising;

the common interface that includes one or more attributes and input/output capabilities that are standard among the plurality of modules; and

logic of a second platform that controls at least one component in the industrial automation system that manages at least one material resource; and

at least one resource module that coordinates the at least one equipment resource control module and the at least one material resource control module, wherein the at least one material resource control module is subordinate to the at least one equipment resource control module; and

a controller that executes at least one of the plurality of modules to facilitate interactions between one or more components of the industrial automation system and at least one of the equipment resource or the material resource of the at least one of the plurality of modules via the common interface.

2. The system of claim 1, wherein at least one of the plurality of modules is an enterprise module that interacts with a Manufacturing Execution System (MES) layer of an enterprise.

3. The system of claim 1, the controller communicates with at least one other controller and associated module to form a control application.

4. The system of claim 1, wherein at least one of the plurality of modules is a device module that interacts with input/output (I/O) devices.

5. The system of claim 1, the common interface includes public interfaces and attributes based upon a common data model.

6. The system of claim 1, wherein at least one of the plurality of modules is implemented as at least one of a class or template, the class or template are included in a library.

7. The system of claim 1, at least one of the plurality of modules includes one or more attributes accessible via the common interface, the attributes include one or more properties, the properties include at least one of a fault property, a status property, and a module availability property.

8. The system of claim 1, at least one of the plurality of modules publishes one or more verbs via the common interface.

9. The system of claim 1, the at least one of the plurality of modules executes as part of a scan cycle for the controller.

10. The system of claim 1, the at least one of the plurality of modules employs local data mapping for functions resident on the controller and message data mapping for functions remote to the controller.

11. The system of claim 1, at least one of the plurality of modules interfaces to at least one of the controller, a third party device, proxy logic, or an MES application via the common interface.

12. The system of claim 11, the common interface supports remote web language applications.

22. The system of claim 1, wherein at least one of the plurality of modules hides details of interfacing to the plurality of components of the industrial automation system.

13. A method to facilitate module and controller interactions, comprising:

identifying a resource that performs one or more actions in an industrial automation system from a plurality of resources to wrap in a first module, the plurality of resources includes at least one of a machine resource, a personnel resource, an equipment resource, a device resource, or a material resource in an industrial automation environment;

defining logic to control the one or more actions performed by the resource, wherein the logic controls a state of the resource;

determining at least one standard interface exposed by the first module independent of a platform of the logic;

associating the at least one standard interface with at least a second module;

deploying the first module, comprising binding the first module to at least one runtime process that utilizes a hierarchical common data model; and

executing the first module on a controller.

14. The method of claim 13, further comprising linking the controller to layers that are common to a layer associated with the controller.

15. The method of claim 13, further comprising partitioning the first module into one or more routines.

16. The method of claim 15, further comprising configuring an order of execution for the routines.

17. The method of claim 15, further comprising configuring one or more rules that specify when the routines execute.

18. The method of claim 15, further comprising configuring one or more groups, the groups specifying one or more routines.

19. The method of claim 15, further comprising reading module inputs, reading configuration data, reading interlock conditions, executing control algorithms, triggering alarms or events, or writing to output modules.

20. The method of claim 19, further comprising executing at least one state sequence.

21. A modular system for an industrial controller, comprising:

a processor coupled to memory, the processor configured to;

encapsulate at least one resource that performs one or more actions in an industrial automation system from a plurality of resources of an industrial automation environment in a first module, the at least one resource includes at least one of a machine resource, an equipment resource, or a material resource in the industrial automation environment;

incorporate logic particular to the at least one resources, the controls the one or more actions performed by the resource;

expose, by the first module, a standard interface independent a platform of the logic independent a platform of the logic;

associating the at least one standard interface with at least a second module;

deploying the first module, comprising binding the first module to at least one runtime process that utilizes a hierarchical common data model; and

executing the first module on a controller.
