How relabel case designated enum in the state machine

• For the State Machine logic makes me Mad, ideas?

  Hello

  I am a complete newbie to Labview and up to the help of kind people on the forum and tutorials tips, State where I implement a state machine.  However, I can't it behave using logic.

  What I try to do is to test the relay using an automated test procedure.

  The procedure takes the following measures:

  1. a card reader and transistor NI9472 DO turns the relay power via the power of the coil (needs of the variable time period). (It's OK)

  2. account of how can cycles the relay contacts worked, it will easily exceed 100,000 cycles. (It's OK)

  3. every 10 cycles (new variables), the contacts are held closed, load circuit "15A in the state machine" (the current relay is switching, which will be 15 a at 30V) is turned off.

  4. While the State of 15A is off, I need to switch to 'State of 1' and the 'State of the measure' , that it allows the measure to take.

  5. Finally, the "State measure and the"State of A 1"must be turned off and the"15A State switched back on .

  6. this process continues for another 10 cycles and repeats.

  I tried to do by using the States and the logical selection function for different States, where she part works, it does not seem to flow completely.  I'm I missing logic.

  Hoping someone may be able to help, thanks

  I really didn't thing you want to be returning this Boolean value in all States.  You should probably also have a different evolution register for each line of output.  Then you simply adjust those that you need to.

• How can I control a .vi another State machine?

  I've written a VI which is an event focused on the state machine.  Events are operator actions that take place on closing buttons on the front panel.  Each event features one or more state names on the queue of the State.  A state machine then takes the name of the State off of the queue of the State and use them to open the case, containing the functions to be performed... Now comes the desire to interact with this vi programmatically to an another vi.  Given that events cannot be triggered remotely because the keys are of type lock and cannot be manipulated by the property node (value (signal))... Is it possible to add a name from State to State in Quebec to distance... ?  It would be nice.

  I prefer not to add the buttons 'hidden' for the original vi, or perhaps to change the structure of the event.

  Is there a better way...?

  Hummer1

  You use 'Get in line' with the same name in the other VI or using a functional Global Variable to pass the reference of queues for the other VI.

  Then you write the State via 'Element of the queue' names as you would in the VI containing the state machine.

• Buttons does not return to the early state in the state machine.

  Hello

  I downloaded a program that is used to back up data. I used a machine to States with different States. State 1 is initialization, where it moves automatically select the State, which allows to select one of the remaining States to copy the data. The selection is made by command buttons. Once u pressed a button, it goes to that respective State and in this state when you press the backup, the backup of data occurs. Once the backup is located the program goes back to the selection state. So far, it works fine. The problem then. Once he returned to the selection state after that copy was made, then none of the buttons are working properly. Then when it goes back to select State and I tried to select a State, nothing happens, not even the stop button works. I don't know why this is happen. Please help me solve this problem. Thanking you in advance.

  You have many States where you have the event structures ("All data" "given more older that '" young data that ' 'Defined Data') (worse there are two of them in "Data set")

  Each of these event structures are for a "Backup" mouse event down.  A singularity is now why you use a mouse event down on a button.  This really should be a value change event.  But this is not the big problem.

  The big problem is that all of these structures events are set to lock the front until the end of the case of the event.  Well, when you click the mouse down on this button, all 4 of these structures tail event this event.  If you are luckly, one of the event will execute and process the event.  Others, that you will never run because the state machine will not get through these cases.)

  You have multiple structures of event you VI and certainly not buried in the event.

  Reading guard and recommendations when using events in LabVIEW

  Then fix your VI architecture.  You must limit the structures of the event or a separate parallel loop, or to a single case of your state machine that your code will frequently return to, without any other user interaction, in order to service the structure of the event.

• How to create a button in the State with two different images?

  What I mean is... I have a picture that is conveyed as a button that has not been pressed, and I also have an image that expresses the same key but this time it is pressed. Is there a way to ensure that when the button is normal I seized the image of the button upward and then make sure that when I roll on or press the Enter key, the image of the button down?

  Thank you, Ben Charter

  Hi Ben,

  Just create a Menu and with the Normal State is selected, use the fill options to fill an image in the Menu item. Select the rollover / the mouse to the bottom of the State in the States Panel, then assign an image by using the options to fill again. This is a swap of base image using normals and States of Muse down mice.

  Kind regards

• How to hold a button in the State of hitbox in flash

  Hello.

  I created an image with a dozen irregular buttons. Everything works perfectly. Now, I want to edit my file in flash cs5 in a way so that when clicking on a button, the last of the 4 States (the State of hitbox) remains visible until another button is clicked. Now its back to the fist State loop. I'm sure that there must be an easy way to do this, something with a stop code perhaps?

  .

  Thanx.

  Juggling has to do with, if you use SimpleButtons (as you are now... things with 4 frames) and AS3.  Juggling in... If you set the upState to match the downState, and you want to reset back later, you must have that stored upState somewhere, otherwise, he is gone.

  If you use AS2, the approach of movieclip is your only option.

• Race conditions manifested in the state machine in queue

  Hello

  I ' am developing a vi in which I use a design of producer-consumer model.
  the producer s enqueue States for the consumer. but at a certain point in execution of I want to enqueue the next state of the statemachine consumer, within the State of the consumer himself. This causes a problem?
  in other words I have given queue in the loop of consumer can also. so the man the next state of consumers will depend on the data in queue

  Thank you

  I make extensive use of Handleres of Message queue where the "producer" and the consumer enqueue for the same queue.

  A "Firinstance" of work today: here are two screenshots of a part of the same code

  

  

  The top loop controls the State of a semi autonomous process where data is collected.

  1. an event is detected, triggering the start of the measuring cycle
  2. Data are being gathered
  3. Another event tells the top loop that it's time to stop collecting data and "Analize" is sent to the end opposite to the consumer
  4. The buffer empty analize, formats the data and continues to the State of "Log".

  The thing to remember is to use a priority queue.  Enqueue to place free and flush properly, in front of end control.  See also 'A trip to Grandma's House'.

  It is a very powerful technique for applications where you want abstract on the 'what' and 'When' the how and just leave a "do".

  And Yes, if I had chosen a unrestricted data (string, var) rather than an enum type and built the lower loop as a child class, you have a "player".

• Problem adding values to a table with the state machine architecture

  Hello

  I currently have a problem that I have to build a program using state machine architecture and now I want to add a value in a table whenever you press a button, but I would like the table to add the new value, rather than deleting the last value. I can't seem to figure out how to make this work without using while loops and similar. It doesn't seem to work properly.

  It is in the case of measurement.

  The idea is I draw several lines then it records the length of the lines in a table and then I'll take one average this so I can convert pixels into real life SO units. But right now I can't seem to add the information in the table.

  There is a little screw Sub, but I think that they should not be important for this question please!

  What's the problem with just the table help build?

• Elapsed time delay does that once in the state machine

  Hello.  I have problems using the delay to show the seconds remaining on an expectation not in a simple state machine.  I have a front panel countdown indicating the time remaining for the step.  I thought that the delay of elapsed time was the way to do.  The problem is the vi work correctly the first time.  But then after that the calendar does not seem to reset at the time I had put.  If I remove the delay and just stick a waiting time in the State, the vi is exhausted because I expect.  This is just to give the user an idea of the time remaining.  What I missing when using the passage of time, or it's just the wrong tool for the job?

  A small question, is that I would like to move the tasks, in this case the LED outside of the loop, so I don't have to repeat the code.  But when I tried moving them outside with only allow constants within the State, they do not work as I expected.  If you have tasks such as operating a set of Boolean values that you are used in several States, what is the the cleaner way to do it without repeating the code?

  Thanks for the help.

  See how it works for you.

• Helps the state machine

  Hello everyine,.

  I'm working on a state machine. I saw a few videos of the same thing and I need help.

  I have attached the code below.

  My problem is that I can not jump since the first case at the last.

  After the execution of the first case I want LabVIEW to check fot the Boolean control attached to the function select. I used an operator oux during the operation. If the condition of "TERMINATE" is satisfied that I want him to be the last case of local variable is used to turn off the START light.

  at the moment I can't go to the latter case. I want the code to keep control of the State, and whenever the user presses the button END the LED should turn off little matter the time of execution.

  PL suggest ways to accomplish a task... am still a beginner

  Concerning

  Jalashwa

  Hi Sindhurakshak,

  You are welcome. I think that the problem still resides on the Structure of the event to the State "WBS". I can suggest the following (say that everything always ends by WBS what I understand of your current code):

  Remove select it and create a new case event for Boolean switch «end». Location of the enum to cancel in this case, as shown below:
  
  The above change means that if the value of "end" Boolean switch is changed (assuming that this will change to true), the case of the event will be held event 'end', which will then the enum value 'End' to the transition of change. Let's say that if the Boolean key 'end' has not changed (which means that has not been pressed), it should run the rest as shown below:
  

  

  

  I'll leave the enum value 'WBS' in the time-out period, assuming you want the State to always run the "WBS" idle state, unless you press the key 'end' to trigger the transition "Terminate".

  It may be useful

  Warm greetings,

• How to disable auto-start for the virtual machine at the start of merger?

  Hi all

  I use Fusion 2.0.4 to run different OSs and have 4 different virtual machines that are installed. But whenever I start the merger, regardless of the previous state when I stopped him, he starts a specific virtual machine. How to avoid this? I want to start just merge and then choose which machine to start.

  TIA.

  Hello

  Welcome to the VMware Forums!

  In the virtual machine library, there is a star in the list of your virtual machines that you can click and she acts as a toggle to start the virtual machine on the opening of Fusion.

  It is somewhat a weird UI design choice, don't know me either until someone reminded last week.

• Use the state machine to fill cluster

  Hello

  I am trying to create a state machine that is running two States, each State has two items up to a Bundle function and in the cluster. I want the two elements of the State first across, then the second State should run and pass the last two items. Currently, I get only the data of the final State. I have one the vi attached.

  Thank you

  Chris

  You don't actually have a state machine.  What you have is a simple loop, and nothing of what is happening in the previous iterations of the loop is spent in later iterations.

  You must create the cluster in the loop itself and maintatin into a shift register.  Use the bundle by name to update the respective elements of the cluster in each picture of the structure of the case.

  

• Tips to remember when using the state machine in queue

  I was able to work through the convert my architecture of State Machine for a BAU, thus eliminating the use of nodes of property/local variables to send data values to my machine of the State, but rather to send through queues.

  I would like some advice/tips on taking to serve perfectly. Especially, "is not to make" things with queues and how to effectively release a queue, etc.. What is the convention when using queues? Thank you!

• In the state machine loop counter

  Hi all

  I have a state machine, and one State in particular is very busy.  I want to State in a loop several times.  I thought about that, but I don't like them.  Let me know if you have a better idea.

  1 Add a registry to offset as a counter for the State.  The State will keep looping to himself, while decrementing the counter.  If the counter is reset, it will go to the next State.  If this isn't the case, it will keep the loop.  I don't like this, because I'll have to add a register to offset.  If I have a little more State requiring a different number of iteration, I'll have to add a counter for that State.  My main VI will be too shift registers.

  2. Add a loop around the code in my case for iteration.  I do not, because too many wires will be going in and out of the loop.  I don't want to do cluster either.

  With precision.  See this example, each State 5 times before moving earrings.  Beats having 5 shift registers and all of these threads passing through other cases.

• string does not update in the state machine

  Help

  I'm pulling my hair out on this one.

  I have a control over the channel I want to get the value that out of the front at a certain point in a type of State machine architecture, but the value contained in the string of LabVIEW not updated during the enforcement program for the purposes of the block diagram.

  I checked that the VI is not corrupted by creating this simple VI to illustrate what I'm doing. (otherwise empty)

  The length of the string, or the indicator related to the local variable, or updated a probe on a wire connected to the string if during 2 seconds after the start of the VI, something is typed in the control of the chain.

  This could be and OS related issue? -J' I normally use XP not Windows 7 with 2009 and I've never noticed this before.

  Any quick feedback this weekend would be greatly appreciated

  Thank you

  Try setting the chain control to "update the value while typing". (right click...).
