• best method to transmit the PPM (servo control) in series-wireless transmitter? (how to combine binary + whole in a single series byte)

  I'm pulling my hair out here... I hope someone can help to guide me in the right direction.  I'm just learning binary and hex, so please forgive me (and correct me!) if I say something wrong.  I have to give credit when it is deserved, because I use info from a post on theautochannel.com to drive this development.

  I try to control a small indoor RC helicopter using LabVIEW and a USB joystick.  I communicate with a transmitter wireless via rs232 (TTL converted), the Protocol is 125000, 8n1. Each image is 14 bytes 2 bytes of header.  I would like to transmit data PPM (pulse position modulation) which is actually just a 10bits (1024 possible measures) range that dictates the position of the servo, for each channel.

  Byte 3 & 4 are channel 1, byte 5 and 6 are channels 2, 7 & 8 CH 3,... and so on until the bytes 13 & 14 which is CH 6.

  Each pair of bytes begins with "00" (binary).

  Byte 3 & 4 should look like "00 00 00 xx xx xx xx xx", where the first "00" is the header, then "00 00" is the identifier of the servo, and 'xx xx xx xx xx' represents the position of the servo. The identifier is actually integrated in the position of the servo, the bits serve a double purpose.

  That's why it all will look like this:

  CH 01:00 00 00 xx xx xx xx xx (position has a valid range from 0 - 1023)

  CH 02:00 00 01 xx xx xx xx xx (range 1024-2047)

  CH 03:00 00 10 xx xx xx xx xx (range 2048-3071)

  etc... If you convert the binary range, you can see how the second half of the bits ID servo are provided by the range of servo.

  I intend by entry VISA to send every byte to constitute the entire frame, and then I will pause ~ 10ms between frames. However, my question is how the hell should I code this? !!  I think I need to write, take 1 CH for example, bytes 3 and 4 together into a string and then split them back hand to be sent as two distinct bytes.  However, I do not know how to mix my header and the first two bits of my ID servo, which is binary '00 xx', with my servo position (which I know I can write in decimal form, as entry VISA will convert it in binary). Any thoughts on the best way to do so, given all this?

  An empty string character likens to a binary "0"?

  Has totally confused everyone?  I really hope not, but I'm pretty tired so let me know if I need to simplify my question.  I hope someone can enlighten me as to the best way to combine the binary constant w modification of decimals (or hex).  And if anyone has thoughts about a good way to organize my vi together, I understand that too!  Right now I'll just use the structures of sequence... I post my code but at the moment, there is not much to look at

  Thank you very much!!

  No, you do not confuse everyone, but I think you might have confused yourself.

  You basically need to do is to create the array of bytes that will be sent, and then use the array of bytes to a string, so you can send it to the serial port. The creation of the byte array can be done in several ways. You deal with 6 16-bit numbers, of which the lower 10 bits are the values of the position of the servo. I don't know what you want on the front panel to look like, but if you have 6 separate (one for each servo) controls with each set having a range of 0 to 1023 (for 10-bit), then you just have to OR each value based on the number of servo. Put all this in a table, add the bytes of the header and the array of bytes to a string allows to get a string that you can send via the serial port. You can also do this in a loop. Joined a VI to show the two concepts. You have not indicated what version of LabVIEW, is 8.2 you use.

• Resampling in the free transform control

  When I take pictures on internet to change or use em for the inspiration, I often need to resize them. Using Image > Image tool size work if I have the image I'm resizing in a separate window.

  Then I can choose resampling: Bicubic Sharper. However using the tool free to reduce processing an image gives me none this option, causing the image degrade in quality over the free transform.

  Is anyway to resampling for free transformation?

• DC motor control - axis of movement back

  Hi all

  I am currently (trying) to design a control of a servomotor system.

  I use a cRIO 9082, NI 9514 C-module, a servo-drive Kollmorgen AKD and a Kollmorgen servo.

  My main goal is to make the engine during continuous running + 15 deg to-15 degrees and with varying frequencies.

  I checked my system using the 'straight axis' operation - example, that comes with LabVIEW.

  How do I start making a model more sophisticated movement?

  I modeled the DC motor in MatLAB using PID control. I can do something similar in LabVIEW?

  See the image as an attachment to the model of behavior, that I want to accomplish.

  Thanks in advance.

  Best regards

  Hi JZaulich

  You will need to use the NI Control Design and Simulation module to perform the simulation and model of different systems.

  http://sine.NI.com/NIPs/CDs/view/p/lang/da/NID/209850

  If you install this kit there are a good example called "DC speed control Cascade" engine that can show you how to model the motor and continuous control (both speed and current ". There are also examples of servo control.

• Custom control with couple or the input voltage system

  Hello

  I'm relatively new to LabVIEW and this is the first time that I'll use for an application of movement. I have a controller/chassis cRIO-9074 with a few modules NI 9514 IO, servo motors and drives, and I'm trying to do is to use a custom control in my system (a sliding mode control law) to generate the signal for the movement of the engines. I was able to produce a movement OR softmotion but so far I've been able to produce with position, speed and acceleration as inputs and to optimize PID gains. What I want to do is to send commands to torque or tension from the entrance of my right to command control is torque for motors. What I was wondering is if it's possible with the components that I use now and if someone could direct me to useful articles or books that can help me.

  Sorry if is a noobie question but I only worked theoretically with systems of control far and I didn't simulate the results with matlab before that. It is the first time that I had to get the experimental results to validate my proposed control right. Thanks in advance.

  Hi,.

  This may be possible, but since sending the commands of torque or tension directly don't are not supported in scan mode, you can use your 9514 FPGA mode.

  This link describes the components needed to run the FPGA device.

  You should be able to find examples in the Finder for example NEITHER, but here is an overview of the use of FPGA that can be useful as well.

• Servo motor RC directly from sbRIO e/s digital

  Hello

  I would use a Committee sbRIO to fly a RC servo.

  A RC servo control is usually reading a signal modulated TTL level pulse width.

  Calendar will be no problem in using a sbRIO, for the FPGA can manage that.

  But I am concerned about the level of output voltage of the output digital sbRIO; High level, it is specified as being > 2, 7V (max 3, 3V). It seems to be ok with the high level of TTL level requirement, but I wonder if anyone has tried this.

  Thank you very much for comment, that you will have on this subject.

• servo

  Hello.

  I need to educate yourself on the hydraulic servo control with Labview. I have the card DAQ 6024. Can I control the servo-valve with 6024 map and Labview 6.1 and also for the position of the hydraulic cylinder, I will use a lineer potantiomater.

  For example I thank you for your advise...

  Hello

  The 6024 will be able to send and read voltage signals, but you will need to implement the control algorithm in LabVIEW. There is no specific toolkit or a set of functions that NEITHER offer hydraulically controlled. If you have design control tools, you should be able to use it to implement some control algorithms. This application of closed-loop speed will depend largely on the PC that you run it like any process consuming RAM on this PC. Please send any specific questions that you have implemented your control application.

  Hi Lisa,

  From what you say it sounds as if your hard drive is certainly u/s, so there is no point in allowing the CHKDSK to continue further. I think that you need to replace the hard drive (or have an ASP to do for you if you prefer) and then reinstall your system from the recovery CD.

• Qosmio X 70-A - performance cooling fans

  I can say with joy that this laptop is very well done and to make happiness perfectly but it would be very nice if you could either give free fan control or correct.

  Laptop computer quickly becomes too hot and this would be fine if it could be refined a bit so that 60 degrees would be almost fan begins to rotate faster and 70 degrees completely fast.

  The fan gets only at full steam 90 degrees which is abnormal and I think that this could lead to damage part

  Message has been modified: translation has been added

  Each laptop model has some cooling system designed for the hardware platform of the laptop and it is tested, so I think there is no reason to panic.
  Is that Qosmio laptops have the best material on the inside so it is possible that the system is set to cool with the performance of the fans more.

  I don't know what objectives do you need your Qosmio, but if use you it for daily activities such as internet office and write emails, you can use the power saver power plan and change advanced power settings. I think that this will reduce the cooling fan activity and your laptop runs much quieter.

• using the reference find send me modal autoguiding errors

  Hello

  We have an NI PXI-7354 controller not to not/Servo control a player Primatics PN 0-7205-0012 2-axis, 2 rotating turntables Micos DT-120 running.  Recently we know modal errors during autoguiding'-70119 (NIMC_limitSwitchActiveError), move the desired can not be completed, because the entry limit is enabled in the direction of the market. »

  This system has worked for years, a dthi sjust began to appear on homing which occurs once a day.  This happens when the move to find reference goes to the opposite limit, because it is programmed and configured for this purpose.  It then performs a small movement to the front, and then this error occurs.  Now, I understand that this is part of the command search referrer.  It seems as if grace to carry on the switch, or perhaps in the stadium itself when it moves forward to the switch in an attempt to approach of the reverse switch slowly with specific accommodation, that is not actually the switch, and the movement fails.  It is not easy for me to change the switch on the scene, but it can be done.  I wish I could say find reference go further forward, then he actually gets the switch before it he comes again.

  So, I guess that's supposed to happen

  1: the reverse of the race during the domiciliation

  2: switch hits

  3: small forward

  4: move in the opposite direction

  5: Press the switch - success home

  Step 3 moves a pre-programmed amount?  If so how can I change?

  Alternatively, step 3 move until the limit becomes inactive, in which case I'm having bounce or noise on my switch entry.

  I tried to adjust the position of the switch House, there is a small amount of adjustment possible.  I also changed the speed of the stroke finding reference to 50000 c/s 25000 c/s and I have yet to see another failure, but I am not convinced that this is the best and most permanent action plan.

  Any help would be greatly appreciated.

  Have you had a chance to watch http://www.ni.com/product-documentation/4190/en/ ?  Your thoughts sound than the limit switch is always on even after step 3, which must turn off the switch.  Looks like that means to get around this issues is perhaps to change the direction of final approach or the speed of movement.  From this page on the limits to find: http://zone.ni.com/reference/en-XX/help/372134F-01/ni-motion_help/findforwardandreverselimits/ it seems that any direction final approach should work, because in step 3, he should see the switch disable before approaching again, but maybe give changing the final approach response to try.

• 9516

  Hello

  Currently, I am controlling a Newport plate using a cRIO, controller of Servo of Maxon and one NI Servo Drive Interface module. My configuration is:

  • LabVIEW 2011 SP1
  
  
  • F1 OR SoftMotion Module Premium 2011 SP1
  
  
  • cRIO-9074
  
  
  • NEITHER 9516 Servo Drive Interface
  
  
  • MAXON 4-Q-DC Servo control LSC 30/2
  
  
  • Newport Platinum: UTM150CC1HL (engine: UE404CC)

  After looking through the books, I wired the linear step, controller of servo and 9516 module as follows:

  

  (Wiring diagram .doc attached as well)

  Note: the only difference between the pattern of wiring and I install, is that I disconnected the 9516 'Drive turn on' the Maxon "say in." That's fine with the LSC Maxon as if 'say IN' is not connected or to ground potential the power stage is activated.

  Before wiring this configuration, I used the LSC Maxon and the scene of the UTM of Newport with an external power supply and controlled the step with internal potentiometer of Maxon. This succeeded.

  Now I'm trying to control the scene with NI SoftMotion and am following the "Getting Started with NI 951 x series C Modules and LabVIEW" manual. I followed the manual and an axis of configuration and coordinate space in the Project Explorer and then tried to test the scene with the interactive Test Panel. After this step, it's where I run into problems. I can get the scene to move when changing the Position of the target, but any value I enter the Position of the target, the step will be only a small amount. If I put a positive value, it will move a sense, a negative value, it moves in the opposite direction. No matter if I put rev 10 000 or 100 rev the scene moves the same amount.

  In my view, that the encoder works because when I move the scene manually the value of the current Position on the interactive Test Panel changes accordingly.

  I'm a novice at this type of control so am not sure how to make sure my installation works correctly. I don't think that this is because the scene shifts only in small increments. Any help on what I should check/adjust to get my system working properly is much appreciated.

  Thank you

  Kyle

  (Manuals for Maxon Servo controller and Newport Platinum are attached)

  Usually when you have no control of the position and the axis continues to operate, then there is an inversion of the order.  This usually results in a complete couple runaway.  I would lower the position limit back to where is was and Exchange A and / not son.  Try to run it again and see if you have the control.  Don't forget that you have a way to stop the axis(E-stop) in case this new wiring translates into a real runaway.

• Cannot run Simulink DLLs at the same time that the execution of the target time real VI

  Hello

  What I try to do is run a dll created in the Simulink model to control some servo through a CompactRio 9014.

  For the moment, I managed to create three screws

  (1) in the FPGA target that performs the PWM channel desired

  (2) which takes the value of a variable that contains the desired position and network that feeds to the 1st VI

  (3) a VI that is running on the host computer that changes the value of the network variable to change the position

  I can get these three work screw and the servo controlled, but when I try to update the value of the network variable using simulation, by deploying to the target of RT simulation and running, he said:

  ' Access denied: this objective is already used by another host or project. »

  I guess that's because the project is already connected the cRio, so I unplug and am able to deploy the model files.

  However, when I try to run one of the screws in the Targer RT as well as simulation I get the error:

  "This VI is downloaded to the target, but is not present in the project you are trying to deploy.  All the screws on the target will be closed unless you choose to add the missing project VI. »

  With a large number of missing screws...

  I'd do this wrong, i.e. is there a simpler way to control inputs FPGA using the simulation, or is there something I have missed?

  Thank you

  Geoff

  Hi Geoff,

  I think I understand what you're trying to do and what you've done so far.

  If I'm not mistaken you have passed through the SIT connection manager, set your target RT (select DLL, mappings and hardware i/o) and this is his 'magic '.   If this is the case of look for the project pilot LabVIEW which was created by the SIT connection manager.  This should live in the same folder where is your DLL.  Open the pilot project, search for VI driver and open it.  Then go into the Sub - VI # 5 has with the name of the loop rate Base.  It's the Subvi who reads/writes on the material and the reads/writes the data to the DLL/OUT model.  If you want to read the output of your model and then manipulate the data that is where you need to add your code.

  Inside of this Base rate loop VI there is a Subvi with number 4 and called SIT take model Timestep.  This VI is the one who makes the call to the DLL model.  The output of this VI is your data from the model.  This data goes into slot - VI # 5, which is responsible for the drafting of these data to the material.  Since you want to manipulate that data from the model, you need to recover data from the wire coming from the Subvi 4 (SIT take model Timestep) before it gets to the Subvi # 5.

  In this VI of Base rate loop, you will see that there are a few empty block structures.  These images are for you to put any code you want.  The reason is that any changes you make to the driver VI and subVIs that aren't inside of these frame structure will be lost if you decide to go in the connection manager to sit DOWN again and make some changes.  The VI pilot gets new script whenever you do something in the SIT connection manager.  Whatever it is inside these frames will not be erased.

  So, if you have a code you want to run in parallel to the simulation you just have to drop it inside this driver VI.  Very probably within this Subvi 5 (Base rate loop). To add your code just drop the VI in one of these settings and make any changes that him so that he can read the data in the model.    Furthermore, the model (Subvi 5) data in a table.  For the index of each element in the array and its meaning look for a file in the same folder where the DLL is named readme.txt ports.  This file has a description of the inports and small ports and their indexes.

  This VI driver is called when run you the host VI so you won't have to run sepearately.

  Kind regards

  Ricardo
