Equivalent to a record in Pascal or a struct in C. Cluster ponents may be of different data types. Examples: Error information—Grouping a Boolean error flag, a numeric error code, and an error source string to specify the exact error. User information—Grouping a string indicating a user?s name and an ID number specifying their security code. All elements of a cluster must be either controls or indicators. You cannot have a string control and a Boolean indicator. Clusters can be thought of as grouping individual wires (data objects) together into a cable (cluster). 3. Demonstrate how to create a cluster front panel object by choosing Cluster from the Array amp。 Cluster palette. This option gives you a shell (similar to the array shell when creating arrays). You can size the cluster shell when you drop it. rightclick inside the shell and add objects of any type. Note: You can have a cluster inside of a cluster. The cluster bees a control or an indicator cluster based on the first object you place inside the cluster. Create a cluster constant on the block diagram by choosing Cluster Constant from the Cluster palette. This gives you an empty cluster shell. You can size the cluster when you drop it. Put other constants inside the shell. Note: You cannot place terminals for front panel objects in a cluster constant on the block diagram, nor can you place “special” constants like the Tab or Empty String constant within a block diagram cluster shell. 4. You create a cluster constant on the block diagram by selecting a cluster constant on the Functions187。All Functions187。Cluster palette, placing it on the block diagram, and dragging a constant into the cluster shell. If you have a cluster control or indicator on the front panel and you want to create a cluster constant containing the same elements on the block diagram, you can either drag that cluster from the front panel to the block diagram or rightclick the cluster on the front panel and select Create187。Constant from the shortcut menu. 5. Elements are assigned an order based on the order in which they are added to the cluster. For example, if you have two Booleans and you want to update one of them, you need to know which is which. You can change the order of the elements by popping up on the edge of the cluster and choosing Cluster Order. A small number appears next to each object. You can then change the order. (Hint: Click on each object in the order in which you want the cluster order. This will renumber the objects as desired.) Demonstrate how to create a cluster with two Booleans, a numeric control, an 北方民族大學(xué)學(xué)士學(xué)位論文 基于虛擬儀器的超聲波測(cè)厚儀 35 array, and a string. Show that if you change one object to an indicator, all objects are changed to indicators. Modify the cluster order. Emphasize how to easily make clusters using the Create Constant/Control/Indicator options on the block diagram, and by copying/pasting clusters on the front panel. This will save the students significant time when working on a program, and prevent possible bad wires due to incorrect cluster order. 6. One advantage of clusters is that you can use them to group information together to pass into and out of subVIs. Clusters overe the limit of 28 terminals for passing data between VIs. If you have a great deal of information to pass, group it into logical units using clusters, pass a single cluster into the subVI, and then unbundle the cluster in the subVI. Clusters can reduce the number of wires in diagrams, so there are fewer wires going into and out of the subVIs. Explain the diagram on the slide. 7. Bundle function—Forms a cluster containing the given objects (explain the example). Bund
