  1. In a few days my team and me will start a project and I'm a little anxious because I've never work with PXI Systems... If anyone want to tell me a tip, recommendation or something about your experience with this systems, you'll welcome. I'm one of the developers in the crew!. I've experience with cRIO and cDAQ. OG
  2. Hello fellow LabVIEWers, I am trying to get a self developed PXI chassis up and running - with some problems. As this is this my first time developing a chassis, some general questions about 3rd party chassis: If I want to get a 3rd party PXI chassis up and running with MAX I just need to add the right description files into the right folder? otherwise the chassis will be recognized as "undefined"? but will still work - except triggers? Whats my status right now? Chassis is connected via PCIe 8361 - PXIe 8360 and the Connection seems to work
  3. I have an AIT MIL-STD-1553 PXI card, and I am trying to control it using LabVIEW. The card shows up in MAX, and a Test Panel is able to communicate with it, as shown in the attached images. Further, if I open a VISA session with the instrument, it seems to be okay. (I have only tried doing a VISA Open and VISA Close, resulting in no error. Since I don't know any other VISA commands to this instrument, and since it does not seem to speak SCPI, I have been limited to simply opening and closing the VISA session.) However, when I try to do a simple Initialize using the AIT LabVIEW vis, I get an er
  4. 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
  5. Hello, I am developing a PXI system and thought I would use OOP to do all the DAQmx calls for all the different cards in my chassis. It all looks nice and neat and works a treat when running in LabVIEW 2013. All my Network Shared Variables are updated on my host application and the host can happily control the PXI chassis. However, as soon as I try and create an executable to run at startup the code stops working, it simply appears not to deploy. There are no errors or warnings, the PXI executable simply no longer works. I presume I am missing something simple, like a missed che
  6. Hi! I've got a new PC with Win7 and a PXI-Chassis (connected through MXI) with a PXI8231 Ethernet card inside. Everything seems to be correctly installed (no yellow signs in the hardwaremanager) the ethernet card appears in the Network Connections, has a static IP, notices if there is a cable pluggen in, but has no communication (0 packets send, 0 packets received). the card is 'supported' out of the box from Win7, so there are no drivers from NI or Intel. With WinXP everything worked fine. I've already changed the card, but still have the same issue... I tried several days to get it
  7. Hello everyone, Basically i have 2 VIs, one running on a PXI, lets call it PXI.vi and one on the pc, GUI.vi I started testing my application some days ago and after 3 hours of running i got the error in the picture. Error -1073807339 occured at VISA Write in PXI.vi Reason: Timeout expired before operation completed. Then immediately also this error: Unable to locate variable in the shared variable engine. Deployment of the variable may have failed. I restarted the PXI and started the test and it happened again after 2 hours. The third time even sooner. It is always 2 variables that ca
  8. Kello everyone! I have some instruments which i controll over VISA. the software has two parts: one GUI running on a computer and the program running on the PXI to which the instruments are connected. I would like the user to be able to choose the GPIB address of each instrument on the GUI, so i created a cluster of GPIB controls. My problem is that while the same cluster on the software of the PXI gives the posible addresses from the instruments connected to it, on the GUI it does not. One easy solution is the user to write the number of each instrument and manipulate the string but i
  9. Dear List Members, My Boss has asked me to look into new Agilent PXI Chassis and compares it with NI Chassis. The Agilent Salesman provides a list of "superior" performance items, such as: - All slots are hybrid (not like NI that some of them are hybrid) - two 4GB paths (effectively 8GB) for data transfer (as opposed to 2.5 GB for NI Chassis) - Existing of Timing card? and Trigger line? that is more superior than NI? - Better cooling methodology - "Free" Agilent Test Exec Software module I have not had a chance to test this Chassis yet and would like to ask independent opinion of the
