摘要:
A method and system for communicating and controlling remotely devices in an automated facility exchanges electronic messages (“E-mails”) between a server that controls the devices and an operator having a client device that has E-mail capabilities. An automation controller overseeing devices and stations within the facility is configured to send and receive over a network, such as the Internet, E-mail messages containing instructions and information. Accordingly, an operator may be alerted to alarm information, fault codes, and other operational parameters via E-mail, and after correcting the fault code or other problem, the operator may send an E-mail message to the automation controller that the situation has been corrected. The operator may also send and receive other information to and from the devices within the facility. Thus, not only human-to-machine and machine-to-human E-mail communication is facilitated, but also machine-to-machine communications via E-mail.

In order to reduce computation time and cost involved with detecting and diagnosing a fault in a system, simplified representations of components of the system are used to estimate valid intervals for state variables at the components. Generic failure rules are configured to compare the estimated valid intervals to related intervals for the same state variables, from either observations or propagations, for overlap. Failure output vectors are generated based on the comparison, and the failure output vectors are compared to diagnostic matrices to determine a source of the fault.

Systems and methods are described that provide a Heat Flow Model (HFM) graph modeling methodology. Embodiments automatically translate formal HVAC system descriptions from a Building Information Model (BIM) into HFM graphs, and compile the graphs into executable FDD systems. During an engineering phase, a user interface is used to enter parameters, conditions, and switches not found in the BIM. During a runtime phase, real-time data from an HVAC control system is input to the generated FDD system (HFM graph) for fault detection and diagnosis.
摘要:
A system and method are provided for the collaborative charging of electric vehicles. The collaborative charging manages the disbursement of power from a neighborhood transformer so as to increase the efficiency of electric vehicle charging at the residences without significantly altering the existing power distribution and residential infrastructures. Time-flexible loads are shed in order to efficiently allocate energy distribution without compromising the comfort or security of the user. The identities of individual residential power demands can be concealed to protect the user's privacy or made available to further optimize power allocation. The power allocation negotiation may be performed in a residential local demand management client separate from the residential charging station.

Methods and architectures are described that provide function block mobility between PLCs. Each PLC configured with Mobile Function Blocks (MFBs) may forward and execute MFBs from each other. To enable MFB mobility over a communication bus, each PLC having one or more configured MFBs requires a Communication Function Block (CFB) and an MFB directory data block. Each PLC maintains an MFB directory data block to store its MFB directory which is used when other PLCs send requests to check the availability of MFBs they need to run new tasks.

A method and system for generating programming code and/or configuration data for programmable controller and the networks on which they operate is disclosed. In one embodiment, programming code is generated on a centralized server having a web-enabled engineering tool. The engineering tool operates on client devices that are in communication with the server over a network, such as the Interntet. Preferably, the engineering tool runs in a browser application (or other network-interfacing-application) on the client device and a user generates the programming code on the server with the aid of the client device. By centralizing the engineering tool, which may contain a configuration editor and a configuration management tool having version management functionality, a new business paradigm for providing engineering tool services to customers having programmable controllers. In addition, new methods and tools for collaborative engineering of programming code are enabled.

摘要:
A supervisory control system and display client are disclosed. The supervisory control system generates a graphical display representative of an operational status of operational components in a plant, facility or process being supervised. There are typically several types of operational components in the plant, facility or process. The system includes a server in communication with the operational components via a network. The server maintains a plurality of equipment unit objects, each of the equipment unit objects having one or more parameters representative of the operational status of the operational components. A display client is in communication with the server. The display client stores one or more equipment symbol objects, each of the one or more equipment symbol objects defining a graphical representation of one of the one or more operational components in the graphical display. The display client also stores a picture object that describes a location of each of the one or more operational components in the graphics display. The display client requests an update of the graphical display and receives equipment unit objects from the server. A processor in the display client generates the graphical display by processing the one or more equipment unit objects with the picture object and with the one or more equipment symbol objects.
