An electronic module including an electronic component is adapted to be comnected to the chassis. An uninterrupted thermal pathway thermally connects the electronic component of the module to the heat input region of the chassis. The thermal pathway comprises a chimney, a heat channel thermally connected to the chimney, and a heat output block thermally connected to the heat channel A first electrically insulative non-metallic layer thermally couples the chimney to the electronic component. A second electrically insulative non-metallic layer thermally couples the heat output block to the chassis heat input region.

Systems and methods that can enhance protection of alarms and events within an industrial control environment are provided. An alarm security component employs cryptographic mechanisms and techniques to encrypt alarms and/or events related to field devices of an industrial controller system. The specification also discloses two-way mutual authentication using cryptography, thereby ensuring that an alarm is a valid alarm and that the clients using the alarms are authorized alarm clients. Effectively, the innovation can regulate access to alarms and events by unauthorized external entities (e.g., monitors and/or users) by employing cryptographic mechanisms.

A method for identifying memory modifications includes designating a first portion of a first memory as read-only. An abort condition is identified responsive to receiving a write instruction having a target address within the first portion. In response to the abort condition, a second portion of the first memory including at least the target address is flagged as being modified. The write instruction is executed.

A system and method for programming a plurality of agents onto a distributed control system are disclosed. The system includes a terminal that displays a graphical user interface having a plurality of images. The plurality of images includes a first image showing a plurality of selectable templates and at least a first mechanism by which first user input signals can be received concerning the templates, where the templates include agent-type programming, and a second image showing a representation of controllable devices and at least a second mechanism by which second user input signals can be received concerning associations between the templates and the representation. The system further includes a processing device that generates executable programming to be performed by the distributed control system based upon the templates and the associations, where the executable programming at least partly governs agent-type behavior of the distributed control system.

A process controller a procedure module that includes instructions for executing a procedure, and a plurality of supplemental procedure modules, each of which includes instructions for executing one of a plurality of supplemental procedures. The process controller also includes a process monitor processor configured to receive an input electronic signal indicative of a status of a process feature, apply logic based on the input electronic signal, and generate an output electronic signal in response to the input electronic signal. The process controller also includes a sequence engine processor configured to execute the procedure, receive the output electronic signal, apply logic based on the output electronic signal, select one or more of the plurality of supplemental procedures based on the received output electronic signal, and execute the selected one or more of the plurality of supplemental procedures.
摘要:
A system for troubleshooting control programs employs an event log that captures the values of inputs to outputs from the control program only at event times determined by changes in input or output data. The program allows the event log to be reviewed in jumps to only events which cause a change in output value of an instruction or particular change in output value of a particular instruction, greatly simplifying the troubleshooting process. The event log records a particular instruction instance associated with the event permitting the operation of the program to be studied in reverse order. The event log may also record a timestamp of the event allowing time stamped data from different devices to be synchronized with the review of the events.

A radio frequency identification (RFID) component receives a data stream from at least one RFID tag. A controller can integrate and/or embed at least one of the following, 1) middleware that filters the data stream associated with the RFID component, 2) RFID software that provides RFID component software functionality, and 3) a smart component that connects to the RFID component.
摘要:
An alarm provision system comprises a recognizer component that receives an alarm/event and recognizes the alarm/event. A provision component analyzes hierarchical relationships associated with an industrial environment and automatically provides a subscribing entity with the alarm/event and at least one other alarm/event that is related to the received alarm/event, the provision of the at least one other alarm/event is based at least in part upon the analysis of the hierarchical relationships.
摘要:
Systems and methods that efficiently simulate controlled systems are presented. A simulation management component (SMC) controls simulation of a controlled system by controlling a desired number of nodes, each comprising a controller (e.g., soft controller) and a simulated component or process, which are part of the controlled system. The simulation can be performed in a step-wise manner, wherein the simulation can comprise a desired number of steps of respectively desired lengths of time. For each step, the SMC dynamically selects a desired clock (e.g., currently identified slowest clock) as a master clock for the next step. The SMC predicts a length of time of the next step to facilitate setting a desired length of time for the next step based in part on the predicted length of time. As part of each step, components can synchronously exchange data via intra-node or inter-node connections to facilitate simulation.
