Abstract

A system is described herein where an embedded computer method for (‘router’) is provided for full-duplex (two-way) communication between devices and/or instruments and TCP/IP-based networking. This system uses a process development component, which configures the router to communicate with a range of devices. A controller is described that can manage a collection of routers. This controller layer can reside inside the hardware or within the data-publishing layer. Each router is physically connected to devices using physical communication ports. This method offers significant improvements over prior art with respect to open architecture process, control protocols, graphical icon usage, process development, validation, execution, monitoring and messaging. The result data from the device control protocol functions are available for named complex processes and/or inter-device communication in real-time based on data decision algorithms in various formats. This method also describes a secure distributed method of using private networks for the devices.

providing a user interface through which a user defines one or more device classes, and creates one or more device instances of the device classes, wherein each device instance represents a device configured to communicate with the computer system via the network;

displaying a plurality of graphical device icons in an available devices display region, wherein each graphical device icon corresponds to one of the device instances;

enabling a user using a user input device, to select one or more of the graphical device icons, drag the one or more selected graphical device icons into a process definition region, and drop the one or more selected graphical device icons at corresponding selected locations in the process definition region;

displaying the one or more selected graphical device icons at the corresponding selected locations in the process definition region;

enabling the user to define a process to be carried out by one or more devices represented by the one or more selected graphical device icons; and

transmitting data representing at least a portion of the defined process to one or more routers associated with the one or more devices represented by the one or more selected icons.

2. A method as recited in claim 1, wherein the user selects and drags two or more graphical device icons into the process definition region, wherein enabling the user to define the process comprises enabling the user to draw a graphical connection between two of the two or more graphical device icons, wherein the graphical connection represents a physical or virtual connection between two devices represented by the two graphical device icons.

3. A method as recited in claim 1, further comprising receiving a unique name for the defined process, wherein the name is received through user input.

4. A method as recited in claim 3, further comprising associating the user with the named process.

5. A method as recited in claim 4, further comprising saving the named process.

6. A method as recited in claim 5, wherein saving the named process comprises securely saving the named process, wherein the named process is accessible only to the associated user who originally created the process.

7. A method as recited in claim 4 further comprising assigning, by the associated user, the named process to one or more additional users so that the one or more additional users can execute the named process.

8. A method as recited in claim 1, further comprising enabling the user to preset one or more parameters associated with the plurality of devices represented by the plurality of graphical device icons.

9. A method as recited in claim 8, wherein the parameters comprise a device name, a router Internet protocol (IP) address, a router port, and a priority.

10. A method as recited in claim 9, further comprising validating the preset parameters to determine whether one or more of the device name, router IP address or router port have previously been set.

11. A method as recited in claim 10, further comprising prompting the user to change one or more of the parameters if the validation fails.

12. A computer-readable medium having computer-executable instructions causing a computer to implement a process, the process comprising:

displaying a plurality of graphical device icons representing devices available on a network for carrying out one or more defined processes, wherein the one or more devices are in operable communication with a router that is in operable communication with the computer;

receiving user input comprising parametric data associated with a selected device;

validating the parametric data by determining whether parameters defined by the parametric data have been previously defined for a device class associated with the selected device;

if the parameters have been previously defined for the device class, prompting the user to change one or more of the parametric data;

if the parameters have not been previously defined for the device class, saving the parametric data.

13. A computer-readable medium as recited in claim 12, the process further comprising repeating the receiving, validating, prompting and saving steps for each of the plurality of devices.

14. A computer-readable medium as recited in claim 13, the process further comprising:

defining one or more steps in the user-defined process.

15. A computer-readable medium as recited in claim 14, the process further comprising transmitting the user-defined process to a router associated with the devices selected to carry out the user-defined process, wherein the router is configured to cause the selected devices to carry out the user-defined process.
