E Event An occurrence on a device that causes a Fieldbus entity to send the Fieldbus event message. A number can use the digits 0—9 and the letters A—F. National Instruments will pay the shipping costs of returning to the owner parts which are covered by warranty. Any action against National Instruments must be brought within one year after the cause of action accrues. Importing Device Descriptions If your Fieldbus device uses manufacturer-specific device description files that shipped with the device or are available from the device manufacturer, you must import them. Object description Describes data that is communicated over the Fieldbus. With Concurrent Mapping checked, all selected devices are mapped in parallel to speed up the mapping process.

Erase Conflicts and Perform Mapping 6. After you set target addresses, click Map to begin the mapping. O Object An element of an object dictionary. Configurafor variable A common Fieldbus function block parameter representing some value in the process being controlled.
A model for remotely viewing data described in the object dictionary. M Macrocycle The least common multiple of all the loop times on a given link, or one iteration of a the process control loop.
Channel A pin or wire lead to which you apply or from which you read the analog or digital signal. Linkage object An object resident in a device that defines connections between function block input and output across the network. All Class A products display a simple warning statement of one paragraph in length regarding interference and undesired operation. You can open additional specialty windows in the middle frame to configure your ni-fbud block applications, change parameters, and update the schedule.
Confogurator protects you and your computer from large ni-rbus spikes and makes sure the measurements from the devices are not affected by differences in ground potentials.

The best solution is to increase the macrocycle time of the loop that contains the other block s for this device. Function block execution schedule A list of times in the macrocycle when the function block will begin to execute its algorithm. This font is also used for the proper names of disk drives, paths, directories, programs, subprograms, subroutines, n-ifbus names, functions, operations, variables, filenames and extensions, and code excerpts.
Data link time synchronization A time distribution message broadcast on the Fieldbus so that all devices have exactly the same data link time. The ISO is composed of national standards organizations in configurayor countries.
With it, you can set device addresses, clear devices, change modes, and read and write to the devices. National Instruments believes that the information in this document is accurate.

Select the link or links ports on your Foundation Fieldbus interface you want to include in your project in the Added link s checklist. The device list windows show the devices in ni-fbux and group the devices from the same vendor under a folder.
Function blocks are the core components you control a system with. Add Virtual Devices 1. Boolean Logical relational system having two values, each the opposite of the other, such as true and false or zero and one. A macrocyle generally must be at least 10 ms.

It's a community-based project cobfigurator helps to repair anything. Block tag A character string name that uniquely identifies a block on a Fieldbus network.
A technical standards organization that creates international technical standards for computers and communications. Underneath this layer of directories, you will find the individual device description files and capability file.
To avoid this error, convert the project to the latest version when you open the project. A device that is responsible for keeping a link operational. Use macrocycle times that are integer multiples of each other to correct this problem. Fieldbus An all-digital, two-way communication system that connects control systems to instrumentation.
