• Problem when the PWM signal combinning and analog signal TOGETHER!

  Hello everyone,

  first I DAQmx 6212, and I need to run the water pump small (9V - 16V) that should be driven by a PWM signal; I also have a motor (5V - 13V) for a water supply which must be controlled by an analog signal and it has built in a force feedback potentiometer, I logged onto this potentiometer correction + 5V the DAQmx and used the output voltage of the third extremety as a value to diagnose to know the position of the engine.

  My VI shows:

  1 is a normal meter production to create my PWMout signal.

  2 is an analog input, I use it as a PWMin to the LabVIEW to diagnose what is happenning in my pump water through the cycle and frequency.

  3 is an entry of the third extremety of the analog potentiometer.

  4 is an analog output that I used as power supply of the motor valve and I used an AC/DC amplifier for aplify signal the DAQmx and the motor road, between the two (3. 4.) I made a comeback with a few calculations, I had a P-controller to know the real position of the engine valve.

  My problem:

  When setting to 1. and 2. in the same VI only, I get an own PWM output with no problem.

  also with 3. and 4. in the same VI only i can control the motor valve without any problem.

  but when I put all these 4 set found in the attached VI, I have a problem as the engine valve turn continuously without stopping even if I change the position of the valve between 0 and 100%, I should mention that I see a PWM normal outside a signal on my oscilloscope, another thing to delete one of (1 or 2)  and run the engine valve VI works fine without any problems.

  so this my problem, if you can think of any solution please let me know.

  Thanks in advance for your help.

  Kind regards

  Caliente

  Here's your VI, slightly modified so the two analog inputs belong to the same task.  This if only for purposes of illustration, I him have not tested.  You will still need to do some debugging.

  While changing your VI, I noticed another potential problem with your original configuration.  You have configured the two tasks of AI for the same frequency, but read you 10000 samples of one of them and only 100 samples from the other (and throw it most of it).  Data acquisition data are buffered, and if you read as fast as you acquire, the buffer fills eventually.  If you read 10,000 samples of a channel, and the other channel acquires at the same rate, then when you read from the second channel you will get old stale data or an error full buffer.

• Network problem between the machines Win XP and Win 7

  I have 2 machines, a desktop and a laptop.  The office is currently running Windows 7 Pro (installed on 2010-01-01) and the laptop is running Win XP Pro.

  The desktop (Win 7) can see the laptop (XP) on the network and can access the shared folders.

  However, the reverse is not true.  The laptop can detect the office as a computer on the network.  I can double click the icon and see the files of office that are shared.  But when I try to access the content of the files, I get a message that says I don't have permissions and contact the system administrator.

  I also have a problem with the shared printer (connected to desktop Win 7).  Before the upgrade both machines can print, after the upgrade, the laptop (Win XP) stopped printing.  I installed the XP drivers for the printer (using the functionality of additional drivers) on Win 7, deleted the printer on the XP computer connection and he still added.  The XP machine was able to find the printer on the network, but when I try to print, I get an arror message saying that "(l'imprimante peut être désactivé, pas branché ou les pilotes ne sont pas installés)."

  I think that the two problems are related, but I can't understand where is the problem.  Print and file sharing is 'on' on both computers, the firewall is configured to allow printing the file and shares, folders are set to 'share', with "everyone" under permissions and both machines have the same network name.

  Any ideas? Am I missing something?  Is it possible to reset all default values so I can set up the network again from scratch?

  Thanks in advance a lot.

  Probably, you have a misconfigured firewall and/or do not have matching accounts/passwords user on both machines.
  Here are the steps of general network troubleshooting. Just cannot apply to your situation, so just take the bits that are. It may seem daunting, but if you follow the steps in the links and suggestions below calmly and consistently, you will have no difficulty to implement your sharing.

  Problems sharing files between computers on a network are usually caused by 1) a misconfigured firewall or a firewall neglected (including a dynamic firewall in a virtual private network); or (2) inadvertently run two firewalls such as the firewall of Windows and a third-party firewall. and/or (3) do not have accounts to the same users and passwords on all computers in the workgroup. (4) tries to create actions where the operating system does not.

  In Windows 7, go to control panel > everything in Control Panel > network and sharing Center. Click on "change the advanced sharing settings. You don't want to use the residential group unless you have all Windows 7 machines. If you do and you want to use the homegroup, see Windows 7 Help & Support. Otherwise, in sharing advanced:

  Discovery of plug in the network
  Open the files and printers sharing
  Turn on the sharing section Public folder sharing
  Plug the password protected sharing

  A. configure the firewall on all machines to allow traffic to local area network (LAN) as being approved. With the Windows Firewall, turning on window file sharing and printer as the above will take care of that for you. If you are not running a third-party firewall or you have an antivirus/security with its own firewall component program, then you're fine.  With a third-party firewall, I usually set up the allocation of LAN with an IP address range. E.g. would be 192.168.1.0 - 192.168.1.254. Obviously you would substitute your correct subnet. Refer to the safety of any third party program or the user forums for how to correctly configure its firewall. Do not run more than one firewall. DON'T STOP FIREWALLS; CONFIGURE THEM CORRECTLY.

  (B) to facilitate the Organization, put all computers in the same workgroup. This is done from the System applet in Control Panel, the computer name tab.

  C. create the counterpart of the user accounts and passwords on all machines. You do not need to be logged into the same account on all machines and assigned to each user account passwords can be different; accounts/passwords just need to exist and to match on all machines. DO NOT NEGLECT TO CREATE PASSWORDS, EVEN IF ONLY OF SIMPLE. If you want a machine to boot directly to the desktop (a particular user account) for convenience, you can do this:

  Start > Search box > type: netplwiz [Enter]
  Click continue (or provide an administrator password) when you are prompted by UAC

  Uncheck "users must enter a user name and password to use this computer". Select a user account to connect automatically by clicking on the account you want to highlight and press OK. Enter the password for this user account (when it exists) when you are prompted. Leave blank if there is no password (null).

  XP - set up Windows to automatically connect (MVP Ramesh) - http://windowsxp.mvps.org/Autologon.htm

  D. Si one or more of the computers on your network are XP Pro or Media Center, turn off Simple file sharing (Folder Options > view tab).

  E. create share as you wish. In Windows 7 I usually share the Desktop of the user and the Public directory.

  F. you have the job of file sharing (and tested by exchanging a file between machines), if you want to share a printer connected locally to one of your computers, share of this machine. Then go to the printer mftr Web site. and download the latest drivers for the correct system. Install them on the target machines. The printer must be collected during the installation procedure. If this isn't the case, install the drivers and then use the Add Printer Wizard. In some cases, printers must be installed as local printers, but it is outside this response.

• Will I activation problems after the upgrade my motherboard and memory?

  new mobo and the new memory chips

  I just got rid of my old motherboard and old slow memory and got new its all good, but I want to know if im going to have a hard time to activate because I already tried the online activation thing automates and it did not work I got a message saying my product its already in use wich key is logical because I activated with my other motherboard I have the thing of activationg phone tho, I got apreciate any comment on the subget, thank you.

  If your copy of Windows is a retail one, simply use the Activate by phone - and speak to an operator.

  If it's an OEM copy (the key is on a sticker on the case of the machine - is it from OS preinstalled) so it can be transferred to a new machine.

  Activate by phone

  Click the Start button
  in the search box, type
  SLUI 4
  and press the Enter key
  Follow the instructions - but when asked which service you need the ansafone phone, don't answer - it should oblige the operator to answer, who can deal with you.

• Facing many problems on the creation of directory and an external Table

  Question:
  
  The strange thing is that if you look at the question 10-b page 3-41, it says:
  (page 3-41 "Oracle Database 10g SQL Fund. II Vol.1")
  
  Merge the data into the EMP_DATA table that is created in the lab last in the data in the table emp_hist. assume
  EMP_DATA external table data corresponds to the EMP_HIST of table, update the email column
  table EMP_HIST to match the row in the EMP_DATA table. If a row in the EMP_DATA table is not
  match, to be inserted in the tables of EMP_HIST lines are considered as corresponding whenever his first and
  family name are the same.
  
  For me, this issue is built wrong. First of all in the last lab we have not been asked to create EMP_DATA. Secondly, EMP_DATA is empty.
  Thirdly, this question asks us to merge into the table EMP_HIST while EMP_DATA is empty.
  
  Table EMP_HIST currently copied data from the employees table. Structure EMP_HIST:
  
  FIRST NAME VARCHAR2 (20)
  LAST_NAME NOT NULL VARCHAR2 (25)
  EMAIL NOT NULL VARCHAR2 (45)
  
  Anway, I did the merger as follows:
  
  merge into e emp_hist
  with the help of emp_data d
  on (e.first_name = d.first_name)
  When matched then
  game update
  Select = d.last_name,
  e.email = d.email
  When not matched then
  Insert values (d.first_name, d.last_name, d.email);
  
  I get this error:
  
  Error report:
  SQL error: ORA-29913: error in executing ODCIEXTTABLEOPEN legend
  ORA-29400: data cartridge error
  KUP-04040: file emp.dat in EMP_DIR not found
  ORA-06512: at "SYS." ORACLE_LOADER', line 19
  29913 00000 - "error in the execution of %s legend".
  * Cause: The execution of the specified legend caused an error.
  * Action: Examine the error messages take appropriate measures.
  
  On the other hand, I said I'm going to try this:
  
  merge into emp_data d
  using e emp_hist
  on (d.first_name = e.first_name)
  When matched then
  game update
  d.last_name = select,
  d.email = e.email
  When not matched then
  Insert values (e.first_name, select, e.email);
  
  I get this error because the external table is final once its creation is as far as I know:
  
  Error report:
  SQL error: ORA-30657: operation not supported on external organized table
  30657.0000 - "operation not supported on external-organized table".
  * Cause: User attempted on the operation on an external table which is
  not supported.
  * Action: Don't do that!

  I'll mention all the steps that I made it clear...

  I gave scott the following grants:

  grant create any directory Scott;
  grant read on the directory emp_dir to scott;

  -----------------------

  1. create a directory and its been created successfully:

  create or replace directory emp_dir
  like 'F:\emp_dir ';

  Then I made just to make sure that my directory is recognized the following:

  SELECT *.
  OF dba_directories;

  I found the drive among the results...

  OWNER NOM_REPERTOIRE
  ------------------------------ ------------------------------
  DIRECTORY_PATH
  --------------------------------------------------------------------------------
  SYS EMP_DIR
  F:\emp_dir

  SYS SUBDIR
  D:\oracle\product\10.2.0\db_1\demo\schema\order_entry\/2002/Sep

  SYS XMLDIR
  D:\oracle\product\10.2.0\db_1\demo\schema\order_entry\

  ----------------------
  2. I created an external table emp_data (the script is given by the text book): successfully done

  drop table emp_data;

  CREATE TABLE emp_data
  (first name VARCHAR2 (20))
  , last_name VARCHAR2 (20)
  , email VARCHAR2 (30)
  )
  EXTERNAL ORGANIZATION
  (
  TYPE oracle_loader
  Emp_dir default DIRECTORY
  ACCESS SETTINGS
  (
  RECORDS DELIMITED BY NEWLINE CHARACTERSET US7ASCII
  NOBADFILE
  NOLOGFILE
  FIELDS
  (first name POSITION (01:20) TANK)

  
  , last_name POSITION (22:41) TANK
  CHAR POSITION (43:72) by email)
  )
  LOCATION ('emp.dat'));

  --------------------------------

  3. I went to drive F:\ to see if emp_dir file exist or not! I did not see it. I checked the files hidden, nothing. Anyway, I ignored and did step 4.

  "Anyway, I ignored him... "

  and so the rest of your problems. I do not see in the steps you told that acually you created a directory ("folder") named "\emp_dir" on your f: drive. Anything that you create the database will actually create this directory on the operating system. Uttering a directory in Oracle, uttering an external table in Oracle, don't create pointers to Oracle objects will assume just actually exists.

  Hi guys,.
  
  I have the following problem.
  
  1. I have a multi selection prompt where you take 2 years.
  
  2. I have the following columns. Year, month, Exp, calc YEAR (max), calc (min)
  
  3. I need to get the months max and min across all lines. So far, I tried MAX, MIN, RMAX and RMIN without success. However, it is not picking up along all lines. For example,.
  
  2001 1 100050 2001 2001
  .....
  2002 1 244005 2002 2002
  
  I'm sure it has to do something with my aggregation in the computed column, but not quite sure where exactly.

  c max (max (year)) and min (min (year))

  Hello

  You can activate AutoCAD, through activation and the recording interface, you can activate your product 24 hours a day, seven days a week, through the Internet or by e-mail. Or the other option takes only a few steps to complete and requires your product serial number and registration information.

• Reading from the sensor to LabView via rs232 or Subvi problem

  I'm quite new to LabView and not too experienced with instrument control so I was wondering if someone could help me to solve my problem?

  Currently, I'm using LabView 2011 and I'm trying to read pressure DualGauge of Pfeiffer (TPG 262) pressure sensor and display the readings of two pressure on LabView.  However, when I run my program, the pressure readings are not displayed - what is displayed are default 0.00 if same mBar pressure reading a reading of the display of the DualGauge probe.  To connect the sensor, I use a RS232 cable and have managed to find the device on my device manager, so I don't think that the connection is the problem (I've also seen the port appears in the Device Manager, when I connected the sensor via RS232 and USB in my computer).  I also use Subvi Pfeiffer in my code, and I suspect that the problem may be in there.

  Attached is my code and here are links to the manual of the DualGauge and the driver of the software LabView of Pfeiffer

  Double manual gauge - p. 23 and 68 are probably the only things related to the RS232 connection.

  Any help is very appreciated!

  You have not tested really do anything. Devices and MAX Manager displays only the com port that you added to the computer. It does nothing to verify that an instrument is truly connected. You might have the wrong settings of com or the wrong type of cable serial (null-modem is required). I suggest that you start with program such as hyperterminal, PuTTY or MAX and try something simple. It seems that you will receive an acknowledgement returned by the instrument when a correct command is received. Make sure that this simple step that happens.

• Black spots on the sensor of the camera? Same problem as Xperia z

  My 1 week old Xperia m4 double aqua has a problem on the sensor of the camera, I never removed the screen protector back, never dropped my phone, I tried to remove it and persist to test if the problem again, but yes the problem, I tried submerging the phone to clean the phone, still, can someone help me?

• Satellite A200 - problems with the AC adapter / CC

  Hello

  The problem concerns a Satellite A200 (PSAF6A-02H01N).

  Recently, there was problems with the laptop, taking several attempts to boot to Vista, it would lock up while loading or just hang and freeze just after loading Vista.
  But once it was up and the laptop running would be happy working for hours with the AC adapter is plugged in.

  The problem got worse now and the laptop will not load Vista end without crashing.
  We have now reduced the computer down to have only a problem when the power adapter is connected.
  The laptop battery will charge normally with the AC adapter is plugged in and the laptop on standby or off.

  The problem persists with the AC adapter is plugged in and the battery removed.
  The laptop will start and run perfectly with battery and no power adapter plugged. Once the AC adapter is plugged in the laptop indicates that the battery is charging and then after a few seconds it crash or freeze and the only escape is a full stop.
  The laptop will not work under the battery power for 30 minutes max.
  I checked the output voltage of the AC adapter and this seems to be a consistent 19.4 Volts.

  Is this only a problem of AC adapter or the problem with the laptop?

  Thanks in advance...

  I lifted the previous discussions on this problem and found one that was very similar, but unfortunately the user decided not to find the problem of the road, save money and buy a new laptop instead! Hmm. !! .. seems to me like this might be a prob. material. Maybe a new motherboard?... anyone have an idea of what are the costs for that perhaps? .. an ASP or decent technician backstreet?...
