The invention provides improved methods and apparatus for control using field and control devices that provide a virtual machine environment and that communicate via an IP network. By way of non-limiting example, such field device can be an “intelligent” transmitter or actuator that includes a low power processor, along with a random access memory, a read-only memory, FlashRAM, and a sensor interface. The processor can execute a real-time operating system, as well as a Java virtual machine (JVM). Java byte code executes in the JVM to configure the field device to perform typical process control functions, e.g., for proportional integral derivative (PID) control and signal conditioning. Control networks can include a plurality of such field and control devices interconnected by an IP network, such as an Ethernet.

The present invention relates to a system and methodology facilitating automation security in a networked-based industrial controller environment. Various components, systems and methodologies are provided to facilitate varying levels of automation security in accordance with security analysis tools, security validation tools and/or security learning systems. The security analysis tool receives abstract factory models or descriptions for input and generates an output that can include security guidelines, components, topologies, procedures, rules, policies, and the like for deployment in an automation security network. The validation tools are operative in the automation security network, wherein the tools perform security checking and/or auditing functions, for example, to determine if security components are in place and/or in suitable working order. The security learning system monitors/learns network traffic patterns during a learning phase, fires alarms or events based upon detected deviations from the learned patterns, and/or causes other automated actions to occur.

Connection objects or other such data structures facilitate establishing and configuring connections between objects that model components in a process control system. A first set of data structures (e.g. the object connection type structures) identify valid types for component-to-component pairings and the respective roles of each component in the pairing (e.g., parent or child, source or sink). A second set of data structures (e.g., the parameter connection type structures) supply similar information for parameter-to-parameter connections. Together, these data structures can be used, for example, to validate component-to-component connections suggested by the user and to automatically configure parameter-to-parameter connections. Actual connections, both at the component or parameter level, are reflected using parameter overrides within the parameterized object model—with which the connection objects are constructed.

The method defines a user environment based on detected motion data and/or ambient noise data. The user environment is then used to apply an appropriate audio adjustment mode. In one embodiment, the user environment definition further includes location data. In one embodiment, the location data is obtained from one of: a global positioning system (GPS), and network triangulation.

The disclosure provides systems and methods of use of an HVAC graphical interface dashboard. In various embodiments the dashboard includes a weather tab, wherein invoking the weather tab advances to a weather screen. The dashboard also includes an indoor humidity tab, wherein invoking the indoor humidity tab advances to a humidity screen which displays at least a current indoor humidity, wherein the humidity screen interprets a percentage of humidity for a user. A programs tab and a home tab are also provided. A button of the dashboard turns a color, such as an inverse color, when it is touched.

A control system has blocks or other components that facilitate validation of their own replacements, e.g., downloaded via e-commerce transactions. The system includes first and second process control components. The first component is coupled to a third process control component, with which it transfers information, e.g., as part of an active or ongoing control process. The second component can be, for example, an update or other potential replacement for the first component. The first and/or second components can effect substitution of the second component for the first. More particularly, they can effect coupling of the second component for information transfer with the third component and decoupling of the first component from such transfer with the third component. Preferably, such coupling and decoupling occur while the process control system remains active.

Process control system and method with improved distribution, installation and validation of components

A system and method for remote monitoring and control of a Foundation Fieldbus process network utilizes an applet/servlet pair, the applet residing on a remote node on a wide area network such as the Internet, the servlet residing on a node communicably linked to the wide area network and to the process network. The servlet is operative to collect data via the FMS layer from one or more process devices such as field devices residing on the process network and to have translated the collected data and to transmit the translated data via the wide area network to the applet residing on the remote node. The information is displayed to the user by an appropriate interface such as the graphical interface of a browser running on the remote node. The user may initiate communications by instantiating the applet via a hyperlink in a web page or otherwise, and may input and receive information via the browser's graphical interface.

A control system has blocks (30) or other components that facilitate validation of their own replacements, e.g., downloaded via e-commerce transactions (11). The system includes first (30) and second (30a) process control components. The first component is coupled to a third process control component (32), with which it transfers information, e.g., as part of an active or ongoing control process. The second component (30a) can be, for example, an update or other potential replacement for the first component. The first and/or second components can effect substitution of the second component for the first. More particularly, they can effect coupling of the second component for information transfer with the third component and decoupling of the first component from such transfer with the third component. Preferably, such coupling and decoupling occur while the process control system remains active.
