As you can see: 1/ In the producer loop, I read data from two LV2: Wafer Map and Current DUT 2/ In the producer loop, these LV2 are used as output of a sub-VI called "Wafer Map Change". This sub-VI, allows the user to modify the picture indicator "Wafer Map" located in the consumer loop, by double clicking on it. 3/ When the sub-VI has run, it outputs the modified picture indicator (Wafer Map) and the new "Current DUT" coordinates. 4/ The two variables are bundled and converted into a variant. 5/ The variant is subsequently enqueud in the "Main" queue. 6/ This variant is converted back inside the consumer loop, and the picture indicator is unbundled. 7/ Finally, the LV2 of the Wafer Map is written and the modified picture indicator is displayed. This kind of data flow worked a while ago, but now I am faced with the following error (this is my translation from french): Error 1 occurred at: Add an element at the end of the queue in Automatic Test Bench GUI.vi Possible reasons: Labview: One input parameter is not valid. For instance, if input is a path, this one may contain a character forbidden by the operating system, as ? or@. NI-488: The command requires a GPIB co
Only) Owning Palette: Queue Operations Functions Requires: Base Package Adds an element to the back of a queue. DetailsExample queue is a reference to a queue. Use the Obtain Queue function to obtain a queue reference. element is the element you want to add to the back of the queue. This data type changes to match the subtype of queue. timeout in ms specifies the time, in milliseconds, that the function waits for available space in the queue http://forums.ni.com/t5/LabVIEW/error-1-at-enqueue-in-a-producer-consumer-architecture/td-p/2686481 if the queue is full. The default is -1, indicating never to time out. If the function waits timeout in ms and the queue remains full, timed out? is TRUE. error in describes error conditions that occur before this node runs. With the following exception, this input provides standard error in functionality. This node runs normally even https://zone.ni.com/reference/en-XX/help/371361J-01/glang/insert_queue_element_vi/ if an error occurred before this node runs. queue out returns the reference to the queue unchanged. timed out? is TRUE if space in the queue did not become available before the function times out or if an error occurred. error out contains error information. This output provides standard error out functionality. Enqueue Element Details If the queue is full, the function waits timeout in ms before timing out. If space becomes available in the queue during the wait, the function inserts the element and timed out? is FALSE. If queue becomes invalid such as when you release the queue reference, the function stops waiting and returns error code 1122. Use the Obtain Queue function to set the maximum size of the queue. Example Refer to the Queue Basics VI in the labview\examples\general\queue.llb for an example of using the Enqueue Element function. YourFeedback! Poor|Excellent Yes No Document Quality?

LabVIEW Very much like notifiers, queues allow the user to send data from one http://enableintegration.com/blog/labview-tutorial-35-queue-topics/ loop to another. In the case of queues, we can send multiple commands, while notifiers can only send a single command. The key point is that a user can “queue” up multiple pieces of data in a FIFO (First-In First Out) manner. Queues also have built-in wait and error 1 error handling. This video illustrates the 4 functions associated with Queues: Obtain Queue, Dequeue Element, Enqueue Element, and Release Queue. They can also be used to separate the user interface from actions. This video is an excerpt from Enable’s LabVIEW Mastery online video-based training series, originally released in error 1 occurred 2008. There have been several revisions of LabVIEW since then, and although the interface may not look exactly the same, the content of this video is still relevant and applicable. ~Ben Ben Zimmer is a Certified LabVIEW architect who has been programming since 1994.
