120 Instantiation Some FOUNDATION fieldbus devices support instantiation of function or transducer blocks in the device. This means the device allows a command to be sent to it that will create (instantiate) additional function or transducer blocks in the device. After instantiation, these blocks operate like any other block in the device. The 475 Field Communicator supports the commands to instantiate and to delete function and transducer blocks in a fieldbus device. Internal Flash Non-volatile memory that stores the operating system, application software, internal device configurations, Event Captures, fieldbus statistics, and user generated text files. Intrinsic Safety (IS) Circuits that are designed to limit the amount of energy consumed or provided to devices to levels below those that are required to ignite specific types of hazardous materials under fault and no fault conditions. Also a method of providing safe operation of electronic process-control instrumentation in hazardous areas, such as flammable environments. IS systems keep the available electrical energy in the system low enough that ignition of the hazardous atmosphere cannot occur. Intrinsic Safety barrier A physical entity that limits the current and voltage into a hazardous area in order to satisfy Intrinsic Safety requirements. IrDA Infrared Data Association, a non-profit trade association that establishes standards for infrared communications between devices such as personal computers, printers, and handheld devices. The 475 Field Communicator can use an IrDA adapter to communicate with the Field Communicator Easy Upgrade Utility or AMS Device Manager. Lead set A cable with two 4mm banana plugs used to connect to a device. Link Active Scheduler (LAS) The bus arbiter for the segment. The LAS recognizes and adds new devices to the link, removes non-responsive devices from the link, and distributes Data Link (DL) and Link Scheduling (LS) time on the link.
