Resource view for logging information in a modular control system

A computer device comprising:

• a memory to store instructions;
• and
• a processor configured to execute the instructions to:
• receive a request to define a primary resource, wherein the primary resource enables access to a primary domain object handler that corresponds to a logical entity that controls a device or a port, or corresponds to a logical entity that controls another resource;
• identify a primary domain object for the primary resource in a domain object database, wherein the primary domain object maps the primary resource to the primary domain object handler for the computer device, and wherein the primary domain object represents a state of the primary resource;
• identify an interface for the primary resource, wherein the interface specifies one or more commands associated with the primary resource, and wherein the interface is configured to receive the one or more commands through a link from a client;
• identify a state request associated with the interface for the primary resource, wherein the primary domain object handler is configured to send a state message indicating the state of the primary resource in response to the state request;
• receive an event request associated with the interface for the primary resource, wherein the primary domain object handler is configured to send event messages associated with the primary resource in response to the event request;
• receive a request to define a logging resource, wherein the logging resource enables access to a second domain object handler that corresponds to a logical entity that views the state of the primary resource;
• and
• identify a second domain object for the logging resource in the domain object database, wherein the second domain object maps the logging resource to the second domain object handler for the computer device, wherein the second domain object represents a state of the logging resource;
• receive the event messages associated with the primary resource and storing the event messages as the state of the logging resource in the second domain object.

A non-transitory computer-readable memory device storing instructions executable by a processor, the non-transitory computer-readable memory device comprising:

• one or more instructions to receive a request to define a primary resource, wherein the primary resource enables access to a primary domain object handler that corresponds to a logical entity that controls a device or a port, or corresponds to a logical entity that controls another resource;
• one or more instructions to identify a primary domain object for the primary resource in a domain object database, wherein the primary domain object maps the primary resource to the primary domain object handler for a computer device, and wherein the primary domain object represents a state of the primary resource;
• one or more instructions to identify an interface for the primary resource, wherein the interface specifies one or more commands associated with the primary resource, and wherein the interface is configured to receive the one or more commands through a link from a client;
• one or more instructions to identify a state request associated with the interface for the primary resource, wherein the primary domain object handler is configured to send a state message indicating the state of the primary resource in response to the state request;
• one or more instructions to receive an event request associated with the interface for the primary resource, wherein the primary domain object handler is configured to send event messages associated with the primary resource in response to the event request;
• one or more instructions to receive a request to define a logging resource, wherein the logging resource enables access to a second domain object handler that corresponds to a logical entity that views the state of the primary resource;
• one or more instructions to identify a second domain object for the logging resource in the domain object database, wherein the second domain object maps the logging resource to the second domain object handler for the computer device, wherein the second domain object represents a state of the logging resource;
• and
• one or more instructions to receive the event messages associated with the primary resource and storing the event messages as the state of the logging resource in the second domain object.
