It will be explained further in the explanation portion. Data at the input tunnels of a sequence structure is available to all the frames of a sequence structure, as we have done in case structures, no matter whether you are using a flat sequence or a stacked structure.
We can take out the output from any of the frames of a sequence structures. Unlike case structures, there is only on data source available at the output tunnels of a sequence structure. Whenever you use a sequence local variable, you break the left-to-right data flow paradigm, with sequence structures. It is preferable to use sequence structure sparingly because they hide the code. I will data flow in detail in upcoming tutorials. It is preferable to reply on data flow rather than sequence structure to control the order of data execution. In LabView sequence structure is categorized in two major types: Data dependency determines the order of execution of a sequence within each frame of a sequence structure, as in the rest of the block diagram. One or more small portions of a block diagram are included in a sequence structure, or frame of a sequence which needs to be executed sequentially.
Any number of actions can be predefined in a sequence structure but no action can be skipped from a sequence structure.
Giving predetermined order to an action event which leads it to the next event is done in a sequence structure. We have already discussed case structure the other structure that is used in LabView is Sequence Structure.
