Hello there !  
  
I want to use OPEN command and read an TXT file. Offline mode is working like a charm ( txt file contains coordinates) , but when I uploaded the code to the real robot is writing an error on the pedant :

Error 41676 Device access error , and write the path that containts the \*.txt files.

Its a simple code of lines :  
PROC Reading()

VAR iodev file;  
VAR string text;

Open “HOME:” \file:= “1.txt” , file \Read;  
!TPWrite ReadStr(file);  
Rewind file;  
!text := ReadStr(file\Delim:=“,”);  
Runnable:= ReadNum(file);  
Close file;

ENDPROC

the HOME folder the default one.I did not change it . Its on my laptop hard drive

C:\Users\Hanokri\Documents\RobotStudio\Systems\IRB140\_6kg\_0.81m\_typeC\_28\HOME\1.txt

Maybe I need to calibrate the controller somehow, to see my laptop folder ? I connected the robot via Ethernet cable.

I welcome any answer , please : )

Do you have a copy of the txt file on the robot or is it only on you laptop?

It is only on my laptop. But I realized I can not used this methode , the robot is checking its on hard drive only, not on my laptop harddrive .  
Can I use Socket Messaging to get the same result? I mean my rapid code is already upload on my robot and Its in run mode, waiting for 1 value to begin reading incoming X and Y coordinates from my labview TCP/IP connection. I get the string(coordinates) from like this  
…  
SocketReceive socket1 \Str:=received\_string;

…  
then received\_string: = VAR NUM Y\_coordinate . Could It work ?
