Hi friend, tks your help, but I don´t know which IP used for communication of arduino... Which do you indicates me using: the LIFA or LINX? I tried using the LINX, but I know the IP... I need a exemple for know better.

LIFA [officially] does not support and never will support ethernet. LINX supports ethernet for select versions of chipKIT microcontrollers. Check out the LINX documentation at http://www.labviewhacker.com/linx. Post on the LINX forums if you have any questions about LINX.
Ethernet support for Arduino does not yet exist in LINX but it is in the future plans.

este Lifa não woks, someone have a lifa 2011 ethernet that work?

hey all,
@ Uke88 great modify with the Ethernet Interface...
I know aktivity is long ago at this thread... but maybe somebody could find it for help
I tryed also to get the ethernet work... and I checked the protokoll response of Send/Recive funktion at labview.
After some tests i found that the send and recive protocoll is ok but the "checksum_Compute" funktion not work fine in the LIFA_ethernet firmware for Arduino. This means that Labview never could get a positve "Sync" response to work with the arduino.
At first i verifyed the funktion of LIFA_ethernet with original LIFA_Base and found no issues or changes.
in a second step i analyse the funktion "checksum_Compute" and test some basic c programming rules and modifications...
after initalising the checksum variable to zero Labview get a positive "Sync" and comunicate with arduino.
Change at the LIFA_ethernet firmeware in the file LabVIEWInterface.ino
// Compute Packet Checksum
unsigned char checksum_Compute(unsigned char command[])
{
unsigned char checksum = 0; //add the zero initialising to checksum
for (int i=0; i<(COMMANDLENGTH-1); i++)
{
checksum += command;
}
return checksum;
}

HEY TO ALL!! SINCE 2 MONTHS I WAS TRYING TO CONNECT THE ARDUINO VIA ETHERNETH AND CONTROLLING FROM LABVIEW AND ALL MY INTENTS HAVE FAIL............ LAST NIGHT I FOUND THIS FORUM AND I TRIED ALL THE STEPS THAT UKE88 SHARED TO US, BUT I HAD A PROBLEM WITH THE SUB.VI AND THE ARDUINO IN, THE PWM PORT........ I DONT KNOW WHY, SO SEARCHING TO HOW CAN I CONNECT THE LABVIEW VIA ETHERNET SO I FOUND A SOFTWARE CALLED "TCP-COM" THAT IS A PROGRAM THAT CONVERTS THE RS-232 TO TCP/IP PROTOCOL. I JUST HAVE TEST IT AND ALL MY PROBLEMS GET RESOLVED!!!
Thanks for the tip! However, used another software that transfers RS-232 data over TCP

Hello,
I wasn`t able to access your code via drop box, it says error 404 not found. Is it possible for you to reupload or send to my email? I am attempting to establish modbus TCP/IP communcations with my arduino due as a slave and Crio-9057 as a master
