• 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?

• 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.

  

• Need help to stop stop button on my machine of the State system

  Hello

  Can someone help me understand please why my STOP can't stop the state machine, I want to stop the program, that the program is running... and it's sad to say, on my side, that, when I pressed the stop button it won't stop until the loop ends. and what I really want to stop it even the loop runs. I have attached here for your reference my vi...

• 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

  Andy

  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.

• 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!

• 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.

• 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.

• 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

  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

• problem with the state machine

  Hello! I have a VI to monitor a storage tank. I tried to do by creating a simple state machine that changes the value(on/off) of some faucets based on 2 conditions:

  -When a certain temperature reaches a predetermined value AND its derivative is<0, the="" state="" must="" change="" from="" on="" to="">

  -When some time passes, the State should change from off to on.

  Unfortunately I can't get this working as it never changes state (by example, if I start with him always stay on 'on' and vice versa).

  Could you please tell me what I'm doing wrong? I enclose the screenshots of the 2 States.

  Thank you!

  Sounds like your shift which could not not be wired properly.

• 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 use time with the State in MODE Lab machine

  Hello

  I tried to use the state machine with function elapsed time so sequentially, start and stop my code. The arrangement is to start the code for 1 minute then stop for 5 minutes. I have attached the code, the problem is when I place the function elapsed time, exit the while loop it does not, on the other hand when I place it inside the loop it does not work, but it does not give the right signal to move to the next State.

  Could you please take a look at my code and help me solve this problem.

  Ok.. I have modded the example to stop after 2 cycles. Also recommend that you take the free online tutorials of LabVIEW.

  1. run the vi. case statement goes to 'initialize', shift registers are initialized to their constants. GoTo 'wait '.
  2. "start" = false, stay in the current state. If true, switch to the "1 min" case
  3. "Reset timer set off with True of the shift register (counter starts at zero). time elapsed "= false, stay in the current state (1 min). If true, goto "5 min" case
  4. "Reset timer set off with True of the shift from the previous case register (counter starts at zero). time elapsed "= false, stay in the current state (5 min). If true, goto "1 min" case. Also, bool crossing is the search for "true-false" function compares '5 min' to add the number of cycle.
  5. Once the number of cycles reaches 2, stop all loop...

• Unable to get the correct rules table result when the State is unknown

  Hi all

  I use OPA version 10.4. I'm writing a rule by using a table of rules. Requirement is such that when the State is unknown then conclusion should evaluate to 'Others' (for example). Now, I have a condition (text) attribute and attribute of conclusion (text). Now when the condition attribute value is "abc" then attribute of the conclusion must be "xyz" but when the condition attribute is 'unknown' or anything else then attribute conclusion must be 'other '. I tried to implement this in the two table rules in word doc and also in excel table of rule but failed to get the desired result. It assesses the 'unknown' conclusion when the condition attribute is 'unknown '. Please suggest.

  Thank you

  Mounia

  

  

  Hi Pascal,.

  As the table of treaty rules the rules in the top-down approach, so the 'unknown' State should be written before the value condition.

  If she meets the condition of value firstly she neglects the unknown state and gives the value of the conclusion as 'unknown '.

  Hi Sean,.

  Want your comments on that.

  See you soon,.

• Select the column in a table that is defined in the select previous in the statement

  Hello

• Snapshots - how to save the State of the machine before deleting

  Hello

  We have a production VM on a cluster host ESXi5, which was taken earlier (nearly 2 years?). Of course, I want to get rid of the snapshot that he shouldn't have spent so long, and after some research, I'm pretty sure deletion will do what I want (I want to keep the virtual machine, as it is now with all the changes since the snapshot).

  However, I also want to take every possible precaution before to do this because if the changes are cancelled (i.e. if returned to the State of origin before the change), it will create a good amount of work, and I want to keep the virtual machine, as it is currently before deleting the shapshot.

  Is this possible? I read cloning will not clone the snapshot of the files themselves, but the cloned VM will contain changes since shapshot has created or will it be the VM before the snapshot? If the clone itself is a copy of the current computer running (changes since snapshot included), this could be an OK option.

  I don't think another solution could be to stop the VM and copy the VMWare real files somewhere - would this work?

  I am probably being a little cautious with this, but I'm a little nervous about snapshots and I want to make sure that I have all the bases covered... just in case...

  The virtual machine is saved so as a last resort I can restore from a backup, but I would rather avoid this path if possible.

  See you soon,.

  Tim

  This snapshot that one is associated with your virtual machine, which is 2 years old?

  what you think is right about removing it. If you just run this snapshot delete operation, it will merge delta with basic disk (since you instant is very ancient, the size of your delta is probably very much, in this case, this operation may take up very much time to complete) and resulting VM will be your last VM with all changes made after this snapshot was taken too.

  At the time of the snapshot, Deleting, you must also remember that there should be enough space available in your data store where you VM resides, if possible to reach downtime, then make the deletion of the snapshot while VM is powered off, or try opening the process during off-peak hours.

  I'm sure you might have encountered following KB already as you have done enough research on the topic

  VMware KB: Delete all snapshots and consolidate Snapshots feature FAQ

  I read cloning will not clone the snapshot of the files themselves, but the cloned VM will contain changes since shapshot has created or will it be the VM before the snapshot? If the clone itself is a copy of the current computer running (changes since snapshot included), this could be an OK option.

  Cloning will also do the job. Yes cloned VM will be for blocks of basic disk and disk from Delta and merger while then resulting VM cloning will be having only basic disc with all changes that you made after the snapshot.

  I don't think another solution could be to stop the VM and copy the VMWare real files somewhere - would this work?

  The virtual machine is saved so as a last resort I can restore from a backup, but I would rather avoid this path if possible.

  Keep copy of all the files in this virtual machine a safe, desirable for you, but at the same time if you have the frame of this virtual machine already successful backup made so nothing to worry. Your virtual machine can be restored from that successful return. If you want to test the restoration, why not restore you this virtual computer on an isolated network and not little a test for your complete satisfaction before proceeding to deletion of snapshot.

  Note: Do not operate upgraded, this will put your VM around 2 years back State at the time of the creation of the snapshot.
