• Some performances are not completed to help put an end to everything in the model of parallel processes

  Hello

  This question confued me recently, I would use a parallel process of model and to finish running at the same time.

  If there are action steps in order, it seemed that will put an end to the execution of all.

  However, I put a wait instead of steps of the action function, there are a few executions not interrupted while I pressed the button finish everything in the toolbar.

  Hope someone can give me help. Thank you very much.

  PS. the number of testsockets has the value 9 in my teststand.

  I ran your sequence again, and I have reproduced the issue.

  It seems the action of the polls Test for success/failure of the VI at full speed.

  It will consume your CPU resource to 100%.

  So I add some delay in the VI to prevent election full speed.

  Please see the following block diagram.

  

  I tried and it seems resolved the problem.

• Closure of a state machine in queue event with several parallel loops

  I am trying to find the best way to stop a program that consists of an architecture of State machine in line waiting for event with several parallel loops. Can anyone recommend the best way to achieve this in my attached VI? (To browse the forum, this seems to be a frequently asked question, but I have not found a solution that works for me.)

  I look forward to any comments on my as well code, if someone is willing to offer it.

  My program needs:

  If the user press the 'Stop' button, the program should prompt the user with "are you sure you want to stop the program?" and then return to a State of rest or move forward to stop the program. In addition if there is an error, the program should prompt the user to ' clear the error and continue, or stop the program. Then back to the idle state or move forward to stop the program.

  Architectural details:

  The program consists of 3 parallel loops: (1) a loop of event management that places different States of a queue of the State, (2) a State Machine that enters the State that is removed from the queue of the State and (3) a loop error/Shutdown, which deals with errors in the error queue management.

  During normal shutdown, where running handling loop in the case of event 'Program.Shutdown' and 'Shutdown' and the 'Idle' States are added to the queue of the State. In the state machine, the State of 'Stop' is invoked. Special "5000" error code is added to the queue of the error. In the loop of error handling and stopping, "5000" error triggered a prompt that asks the user if they want to stop the program. If the user chooses not to stop, a notifier StopNotif is sent to the State of 'Stop' and 'Program.Shutdown' event case with notification 'Go '. If the user decides to stop, the Notifier sends the notification "Stop". Loop and event management State Machine ends when they receive the notification "Stop".

  In case of error, the program behaves in the same way: If the user chooses to clear the error and continue, the program returns to the status "pending".

  HOWEVER - if the user chooses to stop the program, the program crashes. The author of the notification that is sent to stop the loop of events and State Machine management cannot be read because event Program.Shutdown and the stop State (which contain the function "Waiting to notify") are not active.

  I was able to activate the stop State by Queuing in the loop of error/Shutdown management. But I don't know how to activate the "Program.Shutdown" event by program and thus access the function "Waiting to notify" inside.

  I tried to put the function "Waiting to notify" outside the structure of the event, so the event-handling loop never ends. Placing timeouts on the "wait for declaring" and the structure of the event makes the programme of work, but I want to avoid using timeouts because I don't want to turn my event program into a program of polling stations. I would also avoid using variables or nodes property to stop loops, because that requires the creation of a control/indicator for something that the user does not need to interact with.

  Thank you!

  First of all, close the notifier outside loops with your queues.  Second, you must use a user event to send the message to the event structure loop so that it stop in the case of the stop on an error.

• FDM batch Loader - error 5: Invalid procedure or augument - parallel process call

  Hi guru FDM.

  I am using FDM version 11.1.2.1. I try to use the function in the FDM of FDM batch workbench and received the following errors:

  -Lot controls in the FDM workbench are as follows:

  Batch type - Standard

  Level of process - import

  Process method - series (I tried both serial and Parallel)

  Filename delimiter - _ (underscore stroke)

  -Batch file names follow the instructions in the Administrator's guide - < version > _ < location > _ < category > _ < period > _RR.txt (e.g. 1_TESTING_ACTUAL_Q1 - 2012_RR.txt)

  -J' also checked and the FDM data in the shared drive folder comes with a complete access control (read/write).

  -Batch files have been moved to another file sibiling as OpenBatch with a unique name, but the data could not import into the locations.

  -J' also created and launched the script from a web client and the batch workbench.

  I look at what has gone wrong... I want to ask you expert advice. Any help would be appreciated, thanks in advance!

  Hi all

  Thanks a lot for all your response. This issue is resolved as soon as possible and I want to just share what we have done and close this post.

  By my team, the FDM Task Manager has not been configured properly for the loader commands to run. Therefore,.

  1. to configure the FDM Task Manager

  For the file name, such as we would use the description for the period (e.g. T1 - 2012), so

  2. we need to enable the setting "Allows a description custom period." (in the Admin--> Configuration); and

  3. put the spaces between Q1-2012 in file naming for batch loading (for example, we cannot put ___Q1 2012.txt, must be ___Q1 - 2012.txt)

  The batch charger works fine now.

• can perform us two actions with a single button in two clicks, one after the other?

  Mr President.
  
  can perform us two actions with a single button in two clicks, one after the other?
  
  I want that when I click on the button Add once it add data to the database and when I click again on this button it clears the form data to the empty fields.
  
  Concerning
  
  Tanvir

  In the code, it should be easy.

  The following code adds that a button called butman with text 'ADD '.
  It then registers a listener that will be called if the user clicks the button.

  This listener then calls the runAddData method if you clicked butman while it contained the text of "ADD" and it calls the runClearData method otherwise.
  That's why he will swap the functionality of the button between ADD and CLEAR on each click.

  final Button butman = new Button("ADD");
  butman.setOnAction(new EventHandler() {
            @Override
            public void handle(ActionEvent t) {
                      if (butman.getText().equals("ADD")) {
                                butman.setText("CLEAR");
                                runAddData();
                      } else {
                                butman.setText("ADD");
                                runClearData();
                      } // END IF-THEN
            }});
  

  I hope that's what you wanted.

  Further reflection.
  You might want to run the ADD and CLEAR methods in their own son so that it can run in the background without slowing down your user interface.

  I also reuse rather a single button for several features instead of to apply with hundreds of nodes used only rarely with masses of code to show and hide as needed.

• Implementation of the synchronization steps without using batch or parallel processing sequences

  We use a model of customized integrated process based on sequential process model.

  I have to call the Synchronization Manager in order to use the steps of synchronization when you do not use batch or models of parallel process?

  All operations (locks, Rendezvous, Notifications, queues, etc.) and the steps of synchronization works in any model or a model, with the exception of the synchronization of the lot.

  If you need batch synchronization, your model must use synchronization > advanced > step type specification of batch processing to specify what threads are in the batch. Since you are not from the model of batch processing, I doubt that you have to worry about this.

• What happens when two parallel process call the same VI in an FPGA?

  Hi all

  I was wondering, what happens when say two parallel processes call the same Subvi in an FPGA? I think that the FPGA would create two instances of the Subvi, not sure. Any point of view?

  Thank you

  Altras

  I don't know if the FPGA adds any ordinary special, but in LabVIEW rule and in LabVIEW Real-time, a VI by default is not reentrant.  Therefore, a process that is called when it is already in use is blocked and must wait.

  If the VI is reentrant, however, then you have two (or more) for the VI dataspaces, so that each can run independently.

• Prompt the user for a parallel process

  Hello

  I am developing a software where I constantly read data from equipment. There is a command that requires a password to enter in this software. I tried to use the query the user entry to receive the password for the user. However when the guest user screen opens, my software stops the reading of data from the equipment until the user enters the password. I don't want that. I want to read the data coming from the equipment, while the user inserts the password again.

  Is it possible to run the query the user entered a parallel process during execution of the read data part? Is there another way to request a password from the user?

  Thank you for helping!

  Hi Ariyoshi,

  LabVIEW is based on DATA streams. When there is no dependence on the data between segments of code, and then they run in parallel.

  Put your password dialog box in a parallel loop...

• Multitask single-button

  Hi guys, I'm Kinni. I am correctly with my mission and I fight with my Labview project. Can I ask for help from you guys?
  The question is, I do a single button to perform different tasks. Simply put, the button must execute the task as below:
  One click = LED 1 = T LED 2 = F LED 3 = F

  Click new = 1 LED = F 2 3 = LED LED T = F

  Click new = 1 = F 2 3 = F = T LED LED LED

  Click new = 1 LED = LED 2 = 3 LED F = F T

  and so on...

  Also, this will get done.
