  2. I've got some weird stuff going on with a cRIO project I'm working on wanted to get some opinions on it. The basic architecture is a set of classes that do some process. That process registers with a server. The internal data of the process is held in a DVR and the server get's access to that DVR. Clients use TCP to ask the server to do something, the server makes a call against the classes DVR and returns a response to the client. To simplify the issues I'm seeing I created a class that internally just increments an integer every 500ms. The client asks the server what's the current count
  3. I use crio-9014 with 6 of NI9505 module to control RM-501 robotic arm. but i have some problem to design suitable architecture: 1.Some component need synchronous. 2.Need to store configure,it can change online. 3.If possible, improve control rate. 4.Some of Data is needed for many component.(Joint Position, Joint Velocity, Cartesian Position, Cartesian Velocity) I decide to use QSM in this application,is this good choice?
  4. Hi. I would like to have the digital trigger high for user input time in seconds. Any help is much appreciated. Data Acquisition Final.zip
  5. Hello everyone, I’m not sure which forum is the right one which is why I created two new topics with the same content (one in Embedded and one in VI Scripting) – so sorry for the spamming. I have two questions: How can I generate a cRIO project programmatically? How can I start the “Discovering Devices” tool of the Project Wizard automatically? At first I will describe a bit more what I really want to do: I’m about to write an auto coder which should create a complete new FPGA project on my cRIO system without any user input. In the

  7. Hello everybody, I'm about to write an application that can create a complete new FPGA-Project for the cRIO-system automatically without any user Input. Before I ask my question directly, I will give you a few Information about the system and how it works at the moment. I'm working with a cRIO-system that can have different modules in different slots (max 8). That system should be universally usable which means I can replace one module with another one at the start up and create a complete new project with a different name. Most of the project works (I can find out in which slots wh
  8. I have my CLED practical exam next Tuesday and I'm not sure if I should try to use one of the cRIO example projects that ship with LabVIEW. I have been looking over the sample projects and I can see an awful amount of local and global variables. I want to use an example to save time because I think the exam will be similar to the sample projects but I'm worried I would get penalized for using to many local/global variables. Has anybody had a look at the shipping examples for cRIO like the LabVIEW FPGA Waveform Acquisition and Logging on CompactRIO? What are your thoughts on them?
  9. Hello! I'm trying to use AMQP protocol to send data from a CRIO. I've tried using LabbitMQ and zeroMQ libraries, and when I test it from my computer (windows), it works with no problems. But when I try to put the code on CRIO, there's a lot of errors caused by broken wires. It looks like a .dll or .NET incompatibility. Is there any compatible library for CRIO or some clues about how to make it works?
  10. Hello, I'm currently encountering a problem when accessing FPGA indicator with "Reading/ writing a control" node The FPGA part acquires data every 10µs The RT part Read the indicator every 2000µs But when Running the VIs, I see that the elapsed time between 2 Readings of the indicator change from one iteration to another Can someone help me?
  11. I have a cRIO-9064 with the desktop stand accessory to sell. Where do people sell these things to one another?
  12. Hello i am using cRIO-9066 to produce few analog voltages. I am running crio in scan mode and after i stop running the program, the analog output is still present at the pin. Does anyone know how I could reset the cRIO? Thank you Regards Shravan
  13. Hi all, I am designing the control system for what will be a fairly large machine and I considering the ways the overall system can be architected. I have created systems with a cRIO master and a single cRIO 9144 EtherCAT slave. However I have not tried using multiple EtherCAT cRIOs and/or 3rd party EtherCAT devices like servocontrollers. Has anyone used more than one EtherCAT slave with a cRIO? How many slaves can you realistically daisy chain off one of the newer "value" cRIOs like the 9068? I know this answer will depend on number of scanned variables and the scan engine period. At 10ms sca
  14. Dear all, I am trying to test the remote panel with web server on LV2015 but it always shows "Server does not support Remote Panel". I have already researched some similar topic but still can not find out the solution for my situation. Now I will show the software system as well as my procedure to make my project. First is the system: Now I shows my steps And this is the disappointed result I am doing the thesis with this. so I need y
  15. Hi everyone, I am perceiving some strange behavior in my UDP connections. Every time I re-start my cRIO 9063, the UDP Write block outputs ERROR 66 (LabVIEW: The network connection was closed by the peer. If you are using the Open VI Reference function on a remote VI Server connection, verify that the machine is allowed access by selecting Tools>>Options>>VI Server on the server side.) and it does not transmit. The most bizarre thing is that if I simply stop the execution and re-launch it again (given that I am executing the code of the cRIO in Debug mode from a Windows
  16. Still learning about the cRIO, but thought I'd share some of what I've learned recently. Some background on what was going on... We had a driveline failure on two test stands out at customer site. There are sheer pins in the driveline designed to fail rather than send massive torque through a gear set in ways that is just BAD as it can lead to dynamic testing of the hard guarding (which is always fun!). Long story short, there was a failure more of the sheer pins that required detection of the sheer pins breaking. Worst case conditions is the break occurs at 6000 RPM and the only thing tha
  17. Hi, My company has been developing and maintaining its own SCADA software in LabVIEW for a few years. It is fairly comprehensive: datalogging, graphing, alarm monitoring, automation, loops for equations and PIDs, and so on. It is a PC-based solution and communicates with many different kinds of hardware through the COM(RS232), USB, and Ethernet ports of the PC. This solution works well and allows keeping the costs low for most of our customers. Most of the loops run around 10Hz (100ms). However, more and more we are running into customer specifications that require high control rate (f
  18. See the attached screen shot. This crashes compilation. "some of the compilation steps were not executed. refer to the Xilinx log†The xilinx log is what looks like hundreds of pages. I see many warnings, but nothing that looks like a critical failure. If I replace the sine wave with the square wave function, the code will run fine. I am running a cRIO-9067, with an NI-9269 module. All I am looking for is a simple output sine wave VI. Freq and amp variable going in, and a waveform out of the RIO. Any help would be greatly appreciated. I have been using NI's examples (
  19. Hi all, I am trying to get images from a GIGE camera connected to the secondary ethernet port of cRIO 9082. I cannot see my camera in MAX. I have installed NI IMAQdx, NI Vision RT in cRIO. I cannot see NI IMAQ server as an option to install if I go to the custom installation page. Is that the problem? If so how do I get it? P.S: I can see that LabVIEW Real-Time 2013 Support for NI-IMAQ 4.9 is installed in my PC Regards, Prabhu
  20. Hello! Is there anything similar to "DMA MEMORY" that behaves like DMA FIFO, but without the FIFO part? I would like to transfer 1000 bytes of data from the FPGA to the cRIO host and 1000 bytes of data from the host to the FPGA and I don't care about old data - I only need the latest data. Ideally I would like to have two pieces of memory, each 1000 bytes long. One piece that can be written from the FPGA and read from the host and the other piece that can be written by the host and read by the FPGA, so that the first byte of data is always on the address 0. DMA FIFO is not a viable
  21. I'm working with a contractor on a cRIO-based test system, and we are arranging a shared version control scheme so I can work on the code as well. One issue is that there are 2 different cRIO systems operating in completely different network environments, and there are currently 3 different locations where we have to change the IP address between environments: 1. RT controller properties in project 2. A front-panel control on a UI vi that connects to the RT controller 3. A constant in an RT Main vi to set the target for the FPGA BitFile I'd prefer to make this more portable and more eas
  22. I am looking to get some design consideration for developing a cRIO motion control application. My questions are 1. Is Softmotion advisable to be used for motion control where the data rate can is upto 20KHz? Not sure if SoftMotion only works with scan engine and according to cRIO developer guide, for rates >500 Hz FPGA should be used and not scan engine. What are the limitations of using Softmotion? 2. In one application can FPGA be used to do I/O with one module and scan engine be used to do I/O with another module? Just wondering how long does it take to develop a LV application with
  23. Hi everyone, I will be presenting TS1360: "Implementing an Efficient Moving Average Filter in LabVIEW FPGA" on Thursday 1-2pm. Room 16B. These techniques are relevant for developing any sort of code on the FPGA, not necessarily filters. Many of the findings are a bit counter-intuitive for someone used to developing regular LabVIEW code or even Real-Time LabVIEW code. Hope to see some of you there or bump into you in the corridors of the Convention Centre! Cheers, Neville.
  24. Just recently I bought the cRIO Profinet IO C - Series module, it came with a CD so first thing I did was install whatever necessary from the CD into my computer. Next thing I did was follow every single step provided from http://download.ni.com/support/softlib//embedded%20networks/NI-Industrial%20Communication/profinet/GettingStarted_cRIO_PN_IO-Device.pdf except for Step 3 where it ask me to import my GmBH file into the native software of my other controller (the example uses Siemen S7 HW config) which I want to communicate to because that other controller is still not available for me.
  25. Hello there! I'm currently working on the control of a machine that does a specific measurement while the sensor (composed of several strain gauges) slides along a sled. I would like to acquire the sensor Data and to relate it to the position of the sled. The machine also has simple User inputs as Buttons and simple outputs as LEDs. The motors are controlled by relais which are connected to DOs. I wanted to use the cRIO Wfm reference library for my project because it seems to be great at this task. My current problem is that whenever I try to start a measurement, I get the erro
