TCP - LabVIEW (Client) to Arduino (server)

• LabVIEW TCP/IP Client and server, I need to send commands and receive comments side server from the client regarding the command sent.

  Hi all

  I can configure my two PCs, one as a client and a server very well. I am able to send commands from the server to the client. However, I am trying to determine how I can get feedback from the client to the server that something has changed, or a CQI that the command has been received. How I can do this in LabVIEW with the box to TCP/IP tools, or is there a better way to do it?

  Thanks for your help!

  Best regards

  Once the connection is established, TCP does not care which end is the 'server' and the 'customer '. Data can be sent in both directions using the same read and write functions. So, if you are already able to send data to the client and read on the server, you should be able to do the same to send data from the server to the client, using the same TCP connection.

  If this is not clear, please your postal code so that we can provide more specific advice.

• access licenses client license Clarifications + Server 2012

  Hi all

  I need some clarification in licensing to provide the solution that is right for my customer.

  One of my clients purchased Dell server with preloaded Windows Server 2012 OS (Standard Edition) us (from my company) to replace the
  existing server that has windows Server 2003.

  Now, the thing is customer want to transfer/migrate their client access licenses Server and Terminal Server CALs for Server 2003 to 2012 server.

  But is it possible to transfer/migration of CALs client Server 2003 to 2012?

  In the case of is not possible.
  May I suggest Windows server 2003 to install as a virtual operating system in Hyper-V
  to use their existing CAL?

  And is it as additional permit is required to use Server 2003
  Hyper-V?

  Waiting for your valuable response/solution.

  Thanks in advance.

• Problem with Labview communication with Arduino Uno

  Hello

  I tried to run a simple program in labview through my Arduino Uno R3 all morning and keep running into the same problem: no response from my Board of Directors. I'll catch you up on what I've done so far:

  -flashed LIFA Base to my Arduino
  -Downloaded the driver update of VISA

  written-a the block diagram (I hope) for a led on off function

  When I run the program in labview, the RX flashing intermittent, continue for 30 seconds before stopping. The led on pin 13 is not turned off as it should, and I have no control over the power function light. I also tried a program of control of servo with no response and the same flash of RX. Never the TX flashes.

  I am quite stuck, so any help is greatly appreciated. Also I'm not a comp sci guy, I'm just an engineer in mechanics with a half of C++ so keep pg when it comes to the language of the computer.

  I've attached a picture of my diagram of LED, see if you can spot a problem.

  Thanks in advance!

  SOLVED: Reset the Arduino card after that labview had sent his orders (while the RX light was still flashing). Works like a charm.

• "There is a time difference between the client and the server"

  Unit 4.0.3

  Everything worked very well, and all of a sudden, I'm not able to connect to the server unit using any domain account. When I enter the domain/name username/password, I get this error message:

• Python client for the received string of the server TCP Labview unflatten

  How do decode you, unzip a string flattened in Python which was sent by a LabVIEW TCP server?

  I want to Exchange data via loopback. That's why I take a sine wave and flatten it to string and sent on the network through ServerSine.vi. So I have to decode the incoming data in a way that I have good numerical values as when I draw in LabVIEW. I did so far in python_client.py, but the values are wrong.

  Does anyone know how to decode this correctly?

  
  

• TCPiP betwenn QT-Server und Labview-Client communication

  Hello all,.

  IAM new in network programming with LabVIEW.

  I have a problem of communication of data via the TCP/IP protocol. I created a simple Client.vi that connect to the QT C++ server. If the connection is established, Client.vi sent a simple string "Hello" to Qt-server.

  the problem is: Qt-Server receives an empty string with size 0!

  Client.VI

  

  QT-Server

  QT-feature receive data :

  

  Help, please

  Of a possible problem you have, is that you look for a size of qint16. I'm not familiar with QT or used in the syntax of C++, but the duration of LabVIEW is an int32 and so 4 bytes. LabVIEW Typecast also creates big endian data stream, which means that the length of the string will be-> LSB MSB ordered, do the first 3 bytes in the flow of a 0 byte, causing your routine determine that there are 0 bytes to read.

  You have read 4 bytes for the length parameter, change the byte order for your local boutien, more likely to have to share the big endian to little endian number and think of it as the number of bytes to read for the string.

• How to send data from the client to the server using tcp

  1. as I am new to watch I need help with sending data from client to server. I went through various examples of labview, but each of them also explains transfer of data to the client server. But I need help regardng send data from the server to the client.

  2.i would use the data type variant for sending my data.

  Can someone help me please. Thank you

  Regardless of the meaning. Once you have a connection each end allows it to send data to another. Just create what you want to look like interaction.

  Do you want the client sends a command that request data?
  How do you think the response data to look like?

  You can send variants, but probably not worth the effort.

• How can I implement two TCP/IP servers (on two separate computers) and a TCP/IP client (on the third machine)

  I have an application where I need to send data via TCP/IP from two separate machines to a third machine. The machines are on a local network connected via a network switch. The data are produced independently through data acquisition by two independent machines before are sent to the client on the third machine. Each machine has a network card. Thank you.

  Each server listening on a port separated.  On the client have two loops, each loop tries to open a connection using the IP address of one of the servers on the respective port.  I have this work currently, including the ability to reconnect automatically if a connection is lost.  I could put together a disassembled low example for you if you need.

  It is based on the framework of the STM, you find on the site of NOR and download it.  It includes excellent examples.

• Oracle on Linux and Windows Client question database server: NetMgr Windows and Linux NetMgr

  People,

  Hello. I have installed Oracle Database 11 g 2 server in the Oracle Linux 5 Starter PT853 Instance of database virtual machine. Then I installed Oracle Database 11 g 2 client for 32-bit Windows XP 64 - bit Windows virtual machine. Now I face the problem of connection of the VMs 2 as below:

  
  In Manager Net Linux Server Machine:

  Service name: PT853
  Connection type: default database
  "TCP/IP Protocol".
  Host name: localhost
  Port name: 1521

  Listener: LISTENER
  Protocol: TCP/IP
  Host: localhost
  Port: 1521

  
  I test the Service PT853 with "SYSADM" username and password "SYSADM". The connection is successful.
  In the Windows XP Client computer, the information in the Net Manager is the same, but the connection is not successful. Its details are as below:

  
  NET Service Name: PT853
  Protocol: TCP/IP
  The database Machine host name: localhost
  Port number: 1521
  Name of the Basic Service: PT853
  Connection type: default database

  
  I have test the Service using "SYSADM" UserID and password to 'SYSADM' which are the same with Linux, but this error: TNS: listener does not currently of service requested in connect descriptor.

  
  I followed this tutorial http://www.vmware.com/support/ws5/doc/ws_devices_serial_2vms.html to configure 2 virtual machines in Windows 7 host machine.

  In Windows XP Oracle database Client Installer directory, the "tnsnames.ora" file has an entry that matches the name Service in Net Manager. Directory of database server installation Oracle Linux, the file 'tnsnames.ora' has no entry because I installed the server of Oracle database with the instance of database startup PT853.

  
  I tried to test 2 virtual machines in the way as below:

  In Linux, [user@localhost ~] $ping WindowsXP_HostName
  Release: Unknown host WindowsXP_HostName

  
  At the Windows XP command prompt:
  C:\ping localhost.localdomain
  Its release: ping localhost 127.0.0.1 with 32 bytes of data...
  Reply from 127.0.0.1: bytes = 32 time = 2ms TTL = 128

  
  He meets a few times and then disconnected by itself. It seems that Windows XP is ping itself and not Linux server. The host name of the Linux server is 'localhost' as well. It is a kind of confusion for me.

  
  From the information above, we can see that 2 VMs cannot connect between them. Net Manager in Windows XP Oracle Client unable to connect its Service PT853 with the Oracle Linux database server.

  My question is:

  Can any folk tell me how to connect Oracle Client in Windows XP with the Oracle Linux database server?

  
  Very grateful in advance.

  In the Windows XP Client computer, the information in the Net Manager is the same as below:

  I test the Service using the "SYSADM" username and password "SYSADM" which are the same with Linux and the connection is successful as well.

  IP 192.168.196.102 is Linux. This means that oracle database Client in Windows XP may log into Oracle Database Server under Linux. Don't you think I'm not mistaken? If so, I'm very happy and very grateful to you.

  "Do you think I'm not mistaken?

  By definition, if you can establish a connection, then you are correct.

• Install PeopleTools 8,53 Linux question: Windows Client and Linux Server suite

  People,

  Hello. I install PeopleTools 8,53 Internet Architecture. Database server is Dabase Oracle 11 GR 1 material. Operating system is Oracle Linux 5. I installed successfully JDK7, WebLogic Tuxedo 11 GR 1 material and PeopleTools 8,53 10.3.6, in Oracle Linux 5.

  I've been setting up of database PeopleTools8.53. Because the Wizard installation problem, I created PeopleTools 8,53 database manually using Starter named PT853 Oracle database instance. I have run the following scripts:
  (1) utlspace.sql
  (2) dbowner.sql
  (3) ptddl.sql
  (4) psadmin.sql
  (5) psroles.sql
  (6) connect.sql

  Then, we perform Data Mover script in a Windows Client computer to fill the PeopleTools PT853 database machine Linux Sever instance.
  I have installed Oracle Database 11 g 2 client for 32-bit Windows in my Windows XP 64-bit. The installed directories are below:

  Server Linux machine:
  Oracle_Home: / home/user/OracleDB_Home
  ORACLE_BASE: / home/user/OracleDB_Base
  PeopleTools 8.53: /Linux/PT8.53

  Windows XP Client computer:
  Oracle_Client: /OracleDB_Client_Install_Directory
  PeopleTools 8.53: /Windows/PT8.53

  
  What machine installed PeopleTools 8.53 in customer Windows, it is a step:

  Select the location of the connectivity program directory:

  What directory to select? We select the directory ' / home/user/OracleDB_Home "on Linux?
  Oracle Client tools in Windows XP "Start" menu is used to connect Windows XP with Linux?

  Thank you.

  The answer is «Yes, they use the tools of the Oracle Client installed on Windows XP.» The longer answer is that these client tools communicate with the Linux using TCP/IP database, etc., and exclusive Oracle TNS 'protocol '. This network communication usually occurs on port 1521, but you can configure your server to database for listening on different ports. Alternatively, you can do all kinds of fun things with forwarding port, tunnels, VPNs, etc. for the use of different ports and security protocols. There is much more than that, but basically these Oracle client tools provide utilities communication (drivers) used by PeopleSoft to connect to the database on Linux via the network.

• LabVIEW / TestStand ignores license server settings

  Hello

  I see a rather odd behavior on my computer. We received a new license file to our license server. Once it has been imported, TestStand and LabVIEW used of temporary licenses... I ignored it for a day, but became suspicious.

  The Manager of License tool on my computer detects only the license server and properly displays the access rights for my Suite of Dev (incl. Automated test). LabVIEW and TestSTand can check a property...

  Instead, I get the error message

  LabVIEW development system

  License attempt 1:
  All the available licenses on 'xxx' are currently extracted. (NILM13)
  If you have any questions, contact your license administrator.

  Shows available licenses however License Manager. I already tried to reinstall software of NOR (took awhile...) manually remove, add license server information. I'm getting a little desperate / annoyed.

  Any ideas?

  See you soon

  Oli

  Fixed a problem.

  After the stop & a few reboots of license server, my license works again.

  Seems, it was a "personal matter" between me a license, since only my license server refused to work...

  Enjoy the weekend!

• Problems using Modbus TCP accessible by NI OPC Server

  Hello

  I use OPC OR server to access a module of measure. The accumulation is pretty easy, my system with NI OPC, modbus door and the module connected with RS485.

  There is a thermocouple to provide me with some examples of data.

  But there is the point. I know, my data is in the records to be kept and I can access, but each type of data, I'm train does not bring my outgoing, any other (sometimes huge with e34, sometimes very small as e - 13...) my data sort, I do not understand.

  The type provided by the module must be single precision.

  The address used to be lookout is 41000 Labview in is just 999 and in the 'target' - OPC Server I get some values to 401000 but not useful.

  I also get the same results to access the 301000 into different types.

  Read/write or read-only is equal.

  I tried to tell my mutual FUND values are strings, floats, words, BCD, and all other possible means what mutual FUNDS offered to me, but nothing results in a usable temperature.

  I hope that I missed something and it might suggest.

  Cateros

  Finally, the issue is resolved.

  We tried a few others setting for the device in NI OPC modbus Modbus function 06 use simple written record. Using the Modbus 05 functions for single coil written and use default Modbus byte order.

  These parameters were not default and I tried some combinations but bad not these.

  As the tag data type, we tried anyway and got the content of the Register Holding data [0].

  Now it works, and the value is the casting of Holding register [0] and [1] Holding and I got the temperature.

  Already you are quite right, thanks again.
