• Calculation of power using Rogowski coil

  Hello

  I am trying to decide if I should build a VI or if SignalExpress is capable of calculating power based on my selection of transducer.

  I'm trying to calculate the three-phase power of a system using a 2-wattmeter method. I have a NI cDAQ-9178, Rogowski and a winding module NI 9215.

  Since the output of the Rogowski coil voltage is 90 degrees out of phase from the real wave, I can't simply multiply the voltage and current waveforms for the real power. I need to integrate the signal of the Rogowski coil and then multiplying two signals together.

  Is there a SignalExpress option which allows me to integrate the signal or phase change the output voltage of Rogowski?

  Thank you.

  Hi Jcesar,

  I think that the best way would be to incorporate them into LabVIEW, if you have this option, other wise, a way to do in SignalExpress could also be to add a step in LabVIEW on your SignalExpress project, here you can find a guide who has something similar with a numerical integration.

• How to operate DC 5v USB 6008 relay coil?

  I'm operating relay 5v using LabVIEW and USB as DAQ 6008.

  The voltage maximum o/p of DAQ is 5v. Requires relay + 3.4V and - 3, 4V on the coil (min).

  Since generating a negative tension using data acquisition is not possible. How to trigger the relay using a simple switch on the front?

  Or use a CI for the conduct of the relay, as a ULN2003...

  a leg of the relay to + 5V, the other leg at the end of 2003.  The 2003 ground and hang the lines of data acquisition on the appropriate on the 2003 server entry.  The output digital drive low to activate the relay.

• Modbus Ethernet slave coils and discrete

  Hello

  I have serious problems in the communication more of 16 bits for coils or entered discrete.

  In this forum I read some post little bit about this, tried the possible solution but nothing works.

  Suppose that there is some sort of limitation or error in the ModBus modules available to NI Labview Web pages.

  The idea is very simple:

  I want to sent to 32-bit reels of ModBus Ethernet master to slave and sent 64-bit discreet entrances to the ModBus Ethernet master slave.

  Can someone please give me a helping hand? IM' a sort of beginner with the Labview and would apreciate if someone who has had this problem solved could guit me a hint.

  Best regards, Jorge

  I already solved the problem. After all, the issue was the same and all I had to do was reboot the Modbus slave in one of the PC.

  Thanks anyway for the time.

  I have just a sugestion for people of NOR. Once the bug is known by the community and has resolve, why not make available a version of 'clean' of the ModBus.vi for download?

  It would avoid many post about this same problem and help other developers.

• Calibration of the coils of the signal

  Hello

  I have a pretty complex issue... at least I think it is. I solved this time way back in LabVIEW 7. But when I look at my old vi I don't remember what I did.

  The problem: I have a large set of data Let's say 4000 samples, my data are expected to 10Volts to-10Volts but my saved data passes of 12, 8Volts to-6, 4Volts, I can use a calibration of coils, with a gain calculated and offset:

  Offset = (12.8 + - 6.4) / 2 = 3,2
  gain = (10-10) / (12.8 - 6.4) = 1 041

  applied to the max value: 12.8 - 3.2 (offset) * 1 041 (gain) = 10
  applied to min value: - 6.4 - 3.2 (offset) * 1,041 (gain) = - 10

  See the example:

  But now, I know there is a way to make a non-bobines with more data points calibration Let's say 5, I thought it was something with a polynomal to adapt, but I can't rember...

  Does anyone know how to do?

  Best regards

• MB Ethernet coils fail

  I have

  I have the same problem with the Ethernet MB.
  I need 40 exits.
  The first 16 work perfectly. The next 8 coils do not work, next 8 work, 16 next do not work, then 8, next 24 do not work and work for the last 8. Finally, to activate the outputs 40, I needed 88 coil.

  Because 48 coil, do nothing. Can someone help me solve this problem?

  There is a known bug in Modbus Library of NOR. Here is a corrected version.

• UB12: When I create a part, how can I give the 3D appearance a ring shape (coil)?

  Hello

  My circuit uses a custom coil: 12.13 mm outside radius, inside radius 11,13 mm, height 1. 00 mm.  I tried to make this shape in UB by drawing a circle of radius of 11.63 mm with a thickness of 1 mm.  Then in the 3D settings, I did the height of offset 0mm and 1 mm.  This gave me an object round solid with good height and diameter.  I figured out that if i select Create hole, it will create a depth in the center of the diameter of the circle.

  So, I did a turn on the 3D layer with the same RADIUS as the inner radius of the coil.  I put that to create holes.  The I made another circle on the 3D layer with a radius of RADIUS outside of the coil and solid to define.   Then I selected the two circles and looked at the tab 3D of the Properties dialog box.  I again had a solid object.  How can I be subject to smaller radius with the hole in it the RADIUS substitution more large object without a hole in it, then it is combined a form of ring?

  Or, there may be a better way to make this form of ring?  Of course, this reel surrounds a bunch of components on a PCB, so when you are finished, the 3D view of the coil to "reveal" details on the circuit board in the center of the coil (components, printing, etc.).

  Hi,

  I don't know if that's what you want to do, but take a look at the attachment.  I placed two circles on the 3D layer, 12.13 mm and the other for 11,13 mm.  The inner circle, I put the size equal to the outside circle and I checked the option box 'hole', also on the "Hardware" tab, I did the color of the inner circle that is different than the outer circle.  When you look at the 3D preview, this part looks like a ring.

• XPS 15 9550 coil Whine

  I was hoping that this would not be a problem with models of the latest generation, as it is my understanding that this problem has been fixed by the end of the previous generation. Unfortunately, I don't have sound reel whining on my new XPS 15 9550 when it is connected to the power adapter. When it is disconnected from the adapter, the groan is much less visible. It is particularly visible to me when scrolling in Chrome, for example. Backlight KB makes no difference. It does get a little better when the battery is fully charged, but is still quite audible to me.

  Someone else knows that with Skylake models? I am extremely disappointed at this point, I like everything on this laptop except the whine of the coil and the webcam at the bottom of the screen (which I can live with, unlike the whine of the coil).

• Brother MFC-7420. Usually, it works on Windows 7, it will not print and I have to unload the coil and switch off the printer before Relighting.

  I use a Brother MFC-7420. Usually, it works under Windows 7, but from time to time (maybe 1 in 20 times) he will not print and I have to unload the coil and switch off the printer before Relighting. It is not always the case, but it is enough times to be a nuisance.

• Coil a CSV without scientific notation?

  It gives me a headache! I can't wrap csv files, where the length of the number field is greater than 11 digits. For example 1.23832E + 11 should be 123831961495

  I'm just open in Excel itself, the problem is that when you import the csv file into Access, it pulls in the format of scientific notation and not the full value

  This is the point people are trying to do.  That's why Roger said to open the csv file in a TEXT Editor.  Excel is not a text editor.  Access is not a text editor.

  Your csv file is nothing more than a plain text file.  Open in Notepad and you will see exactly what was written about everything that created the file.  Any difference between that and what you see in Excel or Access, or anything else is the result of the way in which these programs attempt to interpret the file and is beyond the control of Oracle.  MS products are (in) famous for trying to be smarter than the user and the interpretation of entry of how Bill thinks it should be rather than what you want.

• Utl_File or standard coil

  Hi all

  I have a table that contains data of round 1, 11, 23, 456 files I need to export to a flat file (.txt) with a ' |' delemiter.

  Please let me know which is the best way to use utl_file mechanism or standard coil (in terms of performance).

  Thank you

  UTL_FILE is an operation of e/s side server on the server's file system.

  COIL is a SQL * more the client operation I/O on a file system of the client.

  Two very different things.

• the coil does not return the result of the query

  Hi people, I just my adventure begins with oracle sql basics course and I encountered the first problem.

  exsample:

  Employees;

  spool off;

  all advice?

  You said "after the execution of the statement.

  What you posted is NOT a statement; It is a script.

  I select Run Script (F5) and the file contains the query and the result set.

  If you use "Run the statement", you will get a file.

• All files generated by a coil in sqlplus receive ownership of oracle: dba instead of the user of the BONE started sqlplus and run the script. There's a file with users owners of BONES of the coil.

  All files generated by a coil in sqlplus receive ownership of oracle: dba instead of the user of the BONE started sqlplus and run the script. There's a file with users owners of BONES of the coil.

  Script launched in until OS user 'A' on the 'A' server which launches sqlplus, then connects to a remote database through a service of tnsnames.ora as another user of the database and the results of this script are spoulées on the server "A".

  The file queued on the old server is written with rw-rw-r: read write user, group read the writing, reading and possession header that is the user of the OS. The file queued on the new server is written to rw-r-r user: reading writing, reading group, public reading and ownership oracle: dba.

  "" The user then has no privileges to modify the file and continue the process of transmitting the file, editing and deleting the file for the next set of commands. This allows us to keep the possibility to migrate to the new server we are unable to process orders.

  $ORACLE_HOME/bin/sqlplus - s user/password@prd1 @./script/CustomScript/R12_OM_UFPC-oracle.sql

  Background: old server running 4.8, Oracle 10.2.0.4 OEL

  New server running OEL 6.5, Oracle 11.2.0.4

  Tested so far:

  File and update umask to 0002 instead of 0022 is now generated as rw-r-r. However, the property is still oracle: dba.

  Update of ownershipt of $ORACLE_HOME/bin/oracle.exe of oracle: oracle (edi added the user to the oracle group) and chmod 6751 oracle.exe. This created several problems where crucial scripts, that is to say of sqlplus failed to run.

  Added! chmod 755 output.file.name - OS user 'A' is not allowed to change to mod.

  Added! command cp MV output file and that generated the file as a user of the operating system: oracle. It is a potential work around in case of emergency, but the developer would have to rewrite the countless scripts.

  Any ideas?

  I have reproduced the behavior of the old server and am able to spool a file via sqlplus under OS user. No changes have been made on the remote database server. All the changes have been on the new server hosting a small 11.2.0.4 database on a server running OEL 6.5 32 - bit OS.

  (1) removed the sticky bit $ORACLE_HOME/bin/sqlplus using chmod u-s, g-s, o - s suggestion of Billy ~ Verreynne

  (2) modified the main group for the 'oracle' user match the user operating system applications, while maintaining membership in the groups 'oracle' and 'dba '.

  -We are dealing with here EDI processes, so the Group was called edi.

  (3) modified property of the files tnsnames.ora and listener.ora for oracle: edi

  (4) restart the receiver

  (5) disconnect / reconnect

  Script runs as expected, the output file contains the correct ownership and permissions.

  Thank you all for taking a look and offering options.
