• Waiting for data on serial port

  Hello everyone.

  I'm trying to figure out how I can solve a problem on LabView. I programmed an Arduino board to read and send a data table of the accelerometer on the serial port. I want to LabView to receive the data and graphs it. My problem is that Arduino send data on an ongoing basis and sometimes LabView can not cope with traffic and read some values "0".

  Is it possible to wait for the data and solve this problem?

  I joined my current vi.

  Thank you much in advance.

  Once again, thank you very much.

  Given that you send ASCII characters, change your Arduino code to send a character to end of line (10 byte value) at the end of each transmission.  Your code is already configured to use it.  Then you need not use the bytes to the Port at all.  Suffice to say the VISA of reading to read a large number of bytes.  Playback stops when it finds the stop character (value 10).  Your code will get a lot easier from there.

• A time waiting for data acquisition

  What is the best way to increase the time of settling on measures Visual C++ of the PXI-6255 A to D? We needed to make some changes of material which gave rise to a measure by a voltage divider high resistance (24.7 k and 100 k) with secondary action on a voltage close to the ground. Switching between the two sources leads to images ghosts/crosstalk effects. We don't have a way to make changes to the material at present. Reduce the frequency of sampling is useful up to a point, after which the voltage reading is still low.

  I tried to use the daqmxsetswitchdevsettlingtime function, but have been unable to find documentation on the first parameter, char deviceName []. What is the name of device?

  If this function is deprecated, there's a replacement feature for this?

  Switching functions of NOR apply only for NI Switch hardware. What you want is to change the clock to convert to change the time channel inter.

• Waiting for data

  OPERATING SYSTEM: AIX
  DB: 11g
  
  
  In a physical configuration of the standby database, I had to perform incomplete recovery to my primary database and because of that I had to open my primary database with resetlogs option.
  
  What should I do with the database of the previous day, I need to create another as the orde of my primary is reset with the LSN 1?
  
  Concerning

  When STANDBY_FILE_MANAGEMENT is set to manual on standby and you add a data file to the primary, then the data file is created in Eve DB under the $ORACLE_HOME/dbs location when the redo data is shipped from primary to standby mode. And finally, the MRP stops.
  You can check the link I gave in my previous post.

  If redo data are not delivered before primary and you do not get to see the data file newly added in the standby database using the view v$ datafile, then you will need to place the tablespace in primary DB in backup mode, copy the data from database pending file and update the controlfile ensures.

• GSS stuck "waiting for configuration data.

  One of my clients have 2 GSS 4900 running ver 4.1 (1)

  I can't get the ESG service works properly in a secondary gssm running. Gssm service looks like it starts but if I check "gss status" och "Show System State" that it is awaiting configuration data

  MNT - GSS - 002.nt.se #show - system status

  Standby GSS - 4.1 (1) GSSM - Cisco [Mar 12 Nov 16:10:21 UTC 2013]

  Recorded in primary GSSM: 10.16.0.15

  Ping works fine between the GSS: are and there is no firewall involved (both are located on the same ip subnet).

  I did stop gss and then start gss. Waited for 24 hours, but the situation is the same.

  If I'm running tcpdump on the secondary, I see TCP traffic and UDP between the primary and the secondary, although all UDP packets have a warning of incorrect checksum.

  I have no idea on how to t-shoot, that. Should I do gss disable, remove this gss of the primary gssm and enable gss again in the secondary?

  Notice to lovers?

  Hello

  There seems to be a communication problem. You can do the following and see if the GSS is going to runmode = 5.

  On the standby: gss stop gss disable Then, go into the GUI of the GSSM and delete the standby GSS from the resources tab Then go to standby: gss enable gssm-standby x.x.x.x (IP of primary )
  
  Then in the GUI of primary GSSM, you will again see the standby in the resources tab. Click on it, and check on the activate button, then hit submit. Make sure the standby goes to runmode 5 under "gss status" output.
  If this doesn't work then you can try the below:
  Go to the GUI of the GSSM and delete the standby GSS from the resources tab. On the standby: gss stop restore-factory-defaults Make sure you have a console connection so you can do the initial config on the Standby GSS (add IP, etc). Once done, enter standby:
  
  gss enable gssm-standby x.x.x.x Then in the GUI of primary GSSM, you will again see the standby in the  resources tab.
  Click on it, and check on the activate button, then hit submit. Make sure the standby goes to runmode 5.

• How to wait for HTML when ADF Application sends a 'work' screen while Looking Up data space reserved

  Hello world

  I am trying to write test scripts in Openscript for an ADF application that uses Business Intelligence and support partial-Page rendering.  While it generates data, it sends HTML says his 'work', and then re - makes the area after the SQL call to the database ends.  The script passes after receiving the 'work' page and errors because it cannot find the variables that should have been created.

  How can I make the script wait for the actual page?  I looked through the documentation and looked online but I couldn't find anything relevant (or do not know what I'm looking for).

  Any help appreciated.

  Thank you

  Roy

  OK - problem solved.

  OBIEE sends the page indicating that it is looking up until the actual data returned.  There is an option on the Weblogic OBIEE server in the {WEBLOGIC_HOME}/instances/bi_instance/config/OracleBIPresentationServicesComponent/coreapplication_obips1/instanceconfig.xml file that can be defined (for test/debugging) to delay sending the screen holder place 'research'.}

  This should be added to the file XML between the tags.

  600

  True

  The value indicates how many seconds the OBIEE server waits until it sends to the screen "search.

  I hope that this information will prevent hair pulling episodes by others.

• Storage VMotion - a general error occurred: could not wait for the data.  Error bad0007.

  People,

  I searched through this forum and have not found an answer that works in many positions out there, I say to myself that I would ask him once again.

  Here's the context:

  We have 12 identical Dell M600 blades in 2 chassis with 16 GB of Ram, 2 x Xeon E5430, they are all connected to an Equallogic PS 5000XV iSCSI SAN on a separate iSCSI (vswitch1) with 2 cards network dedicated network and dedicated switch, console svc iscsi dedicated, dedicated VMkernel port for iscsi access. Net access (vswitch0) contains port groups VM for our various networks and a console port and vmkernel svc for VMotion with 2 separate NETWORK cards as well.

  We are running ESX 3.5 U3 and VCenter 2.5 U3 on Win2k3 R2

  VMotion works between all servers, Storage Vmotion works for most machines, HA works and the value 2 host failurs with no monitoring of vm, DRS is set to manual for now I have a few machines on the local stores that I complete my rebuilt LUN, there is no set of rules for DRS and VMware EVC is enabled for guests of the Intel. However, I'll just describe one machine to do svmotion below.

  Here's the problem:

  I'm trying to Svmotion via svmotion.pl - interactive, a Machine to Windows 2000 with a virtual disk and a virtual RDM. I am aware of the requirements for the RDM and required parameters for svmotion, independent is not selected for the RDM, and I also have svmotioned several machines linux and win2k3 with the same configuration without problem. In the interactive session, I choose to individually place the disks and I chose the virtual disk to only the virtual machine to be moved, essentially, as I saw it move vdisk virtual machine and then copy to the pointer of the RDM.

  The use of the processor in this machine is about 25% average. but I try to run migrations at the time the lowest. and The Host it itself shows only about 5.5 GB of the 16 GB of RAM used. so I think we're good on the RAM. the volume/datastore that I'm migrating from has 485 GB free and the volume/datastore I migration towards a 145 GB free. the VM virtual disk is only about 33 GB.

  I run the script the windows version of the RCLI svmotion. and when to begin the process, I get the following error at around 2 percent of the progress:

  "Since the server has encountered an error: a general error occurred: could not wait for the data."  Error bad0007. Invalid parameter. »

  After searching around, I found the following hotfixes to the U2 release notes

  • Migrate.PageInTimeoutResetOnProgress: Set the value to 1.

  • Migrate.PageInProgress: The value 30, if you get an error even after the setting of the Migrate.PageInTimeoutResetOnProgress variable.

  I've made these changes, and I still get the same error.

  When I dig in the newspaper, I see these entries in the journal of vmkwarning:

  At this point, I'm stuck... What is Windows RCLI? the vcenter Server? or the service console with not enough of RAM? We have already increased all our consoles service 512 MB...

  Any help would be greatly appreciated...

  Thanks in advance.

  The vmkernel on out of memory error, I had that before. And vmware support recommends setting 800M Max service console memory. And I did it and have no problems after that.

  See if that helps the issue.

• Still waiting for the new Satellite U840T-102

  We sent the laptop in the subject to support Toshiba in Italy on 5 May. File n. 73040100. After a few emails June 20, we received the proposal to change the product and sending us a new.

  We have NOTHING yet. Our clientele is more waiting for two months for a WARRANTY SERVICE.

  Is this right? It is the policy of TOSHIBA?
  CAN WE HAVE A CERTAIN DATE?

  I understand you very well buddy.
  It s always pity if the laptop is not working properly and if something needs to be replaced.

  I think there is a reason for the delay and I recommend you contact the ASP in Italy once more in order to clarify this matter.

• Should I buy a MacBook Pro now or wait for the WWDC

  Hello

  Well, I want to buy a MacBook Pro (my first one ever). However, I have read on some sites there is a new version of the MacBook Pro this year (at WWDC).

  Now I'm totally confused. I want to use a MacBook Pro 15 "(8 Go de RAM et 552 Go SSD) to work on large data / Business Intelligence technologies and programming."

  But I don't know if I have to wait for these new features or go ahead and buy this one now. And if these new features will be most useful for what I want to do.

  Thanks in advance.

  Apple has specifically discourages discussions on these forums about what and when the new products will be introduced and what changes there may be.

  The best advice is, what your needs are and this current model meets the.  If so, buy it, if not, don't buy it.   My observation of past changes in the introduction of new models is that the changes are incremental, not radical.  My primary MBP is a 2011 model (with 16 GB of RAM and an SSD hard drive) and I still do not feel outclassed by the current culture.

  Ciao.

• "Waiting for in time (RT PXI target) real answer" error when the program is waiting interruptions

  Hello

  I developed an application to detect interruptions generated by an electronic card and act accordingly. The program was developed in labview, but she calls a dll; created with labwindows. The dll is scheduled to open the visa communication, select the events and install the interrupt handler and when an interruption is detected, it reads the value of the different registers of the map and returns to labview to view.

  The problem is that when the program expects an interruption, a prompt appears with the message "Waiting for real-time (RT PXI target) real answer" and the only option I have is to click on the button to disconnect the pxi or just wait. If I wait and I generate an interrupt, the prompt disappears and the application view data as it was planned.

  To wait for the following code the interruption has been programmed into the function:

  While (flag == 0)

  {

  Sleep (1000);

  }

  When an interruption occurs, the value of flag set to 1 and function continues without any problem. I am not really sure, but here is probably the problem and it probably isn't the best way to wait for a break because the sleep function suspends the thread to the configured time, but at least the load calculation in the PXI is between 0 and 1%. I was wondering if anyone knows how to wait for a break without 'lost' communication with PXI and if there is a better way to do it.

  Any response will be welcome and thank you for them,

  Jaime

  Hey there.

  You see problems with connectivity it's because the thread by DEFAULT CallLibrary nodes running in is the UI (UI) thread - UI thread manages also the important things like, say, communications (especially all the connections for the VI server) and other things that you could run all the time.  A CallLibraryNode is not, by default, intended to be used to execute code that runs for a long period of time.  If you want to do this, you assign the execution of the CallLibrary node to run in the context of a LabVIEW run-time engine thread (by selecting to make it work "in any thread") and not the UI thread.  This can be done through the properties of the CallLibraryNode.  By selecting "run in any thread" the call DLL will be generally in the context of the thread running in the run LabVIEW, which is usually what is meant when even.  The VI CallLibraryNode color change of Orange (UI) to blue (LabVIEW thread) so that you can quickly tell what context the appeal will be in.

  The reason the interface thread user is the default thread is because most often DLLS calls need to be serialized (because of functions is not not thread-safe) and so it serves to protect the integrity of the system.  However, if you know your threads are thread-safe, or you will use these threads for a while, it is best to program the CallLibraryNode to use a Thread of LabVIEW execution rather than the UI thread.

• Run VI GUI, don't wait for it

  Hello. I'm using Labview 9.03f. I have a loop of events that deals with the interaction of the user. When the user selects a menu item, I want to run a VI that has its own UI, but I don't want to wait until she finishes execution (to be held until all of the interaction of the user). Basically, I want the new VI floating on top, but the user to always be able to interact with the main GUI.

  I'm looking by using a reference of VI with the RunVI method, and wait until a parameter set to false. What is the right way to go on this subject?

  Thank you!

  psssttt...

  Ref call will wait for the vi calng to return.

  You can use the invoke node ctrl val.set method to pass data before starting.

• Waiting for VISA c# on QR

  I am trying to write a simple program in c# (.NET 4.0) to control a Keithley 2400 SMU by VISA GPIB and I'm unable to switch to the program to wait as the demand for services which the Keithley send at the end of the scan.

  The scan is a scan of simple linear voltage controlled internally by the unit Keithley. I have the device configured to receive a ServiceRequest signal at the end of the scan, or when compliance is reached.

  I am able to send orders to the SMU and read data buffer, but only if I manually enter a timeout between the scan start command and the command to read data.

  A question that I have is that I'm quite new to c# - I use this project (some parts of my code LV Portage) to learn it.

  Here's what I have so far for my c# code:

  using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading;using NationalInstruments.VisaNS;
  
  private void OnServiceRequest(object sender, MessageBasedSessionEventArgs e){    Console.WriteLine("Service Request Received!");}
  
  // open the address
  Console.WriteLine("Sending Commands to Instrument");
  instrAddr = "GPIB0::25::INSTR";
  mySession = ResourceManager.GetLocalManager().Open(instrAddr);
  // Cast to message-based session
  mbSession = (MessageBasedSession)mySession;
  // Here's where things get iffy for me... Enabling the event and whatnot
  mbSession.ServiceRequest += new MessageBasedSessionEventHandler(OnServiceRequest);
  MessageBasedSessionEventType srq = MessageBasedSessionEventType.ServiceRequest;
  mbSession.EnableEvent(srq, EventMechanism.Handler);
  
  // Start the sweep (SMU was set up earlier)
  Console.WriteLine("Starting Sweep");
  mbSession.Write(":OUTP ON;:INIT");
  
  int timeout = 10000;             // milliseconds
  // Thread.Sleep(10000);          // using this line works fine, but it means the test always takes 10s even if compliance is hit early
  // This raises error saying that the event is not enabled.mbSession.WaitOnEvent(srq, timeout);
  // Turn off the SMU.Console.WriteLine("I hope the sweep is done, cause I'm tired of waiting");
  mbSession.Write(":OUTP OFF;:TRAC:FEED:CONT NEV");
  // Get the data string data = mbSession.Query(":TRAC:DATA?");
  
  // Close session
  mbSession.Dispose();
  

  All the foregoing is supposed to imitate this LabVIEW code:

  

  So, any ideas on where I'm wrong?

  Thank you

  It turns out that I need to activate the event as a queue rather than a Manager:

  mbSession.EnableEvent(srq, EventMechanism.Handler);
  

  Must be:

  mbSession.EnableEvent(srq, EventMechanism.Queue);
  

  Source: the documentation under the heading "remarks". It was a pain to find documentation about it... NEITHER needs to make it easier :-(.

  With this change, I also don't need to create the MessageBasedSessionEventHandler.

  The final, labour code (with fluff like the namespaces and classes deleted) looks like:

  rm = ResourceManager.GetLocalManager().Open("GPIB0::25::INSTR");
  MessageBasedSession mbSession = (MessageBasedSession)rm;
  MessageBasedSessionEventType srq = MessageBasedSessionEventType.ServiceRequest;
  mbSession.EnableEvent(srq, EventMechanism.Queue); // Note QUEUE, not HANDLER
  int timeout = 10000;// Start the sweep
  mbSession.Write(":OUTP ON;:INIT");
  
  // This waits for the Service Request
  mbSession.WaitOnEvent(srq, timeout);// After the Service Request, turn off the SMUs and get the data
  mbSession.Write(":OUTP OFF;:TRAC:FEED:CONT NEV");
  string data = mbSession.Query(":TRAC:DATA?");
  mbSession.Dispose();
  

  I hope this helps future programmers.

• Wait for activity on front panel

  Hello

  I have a while loop with a counter (shift register), in which Im can choose how many times its going to count. This loop is used to allow a data in a economy another loop via a local variable to activate it on the VI "write to messurement.

  Now, I wish that my loop counter to count the selected number and then stop, until I press some activate button on the front panel.

  My idea is to use the "wait for activity of façade" in the loop of the meter, to "stop" the loop when the number cunted is reached and then continue, if a key is pressed.

  But I can't really understand how to operate :-(
