VISA question GPIB - SOCKET - INSTR

[hugoc]

Hi,

I am trying to comunicate with a YOKOGAWA OSA through TCPIP::xxx.xxx.xxx.xxx::INSTR and I am having an error.

First I have tried to  use GPIB which works fine. After this I was also trying to use ethernet connection but I am not having success.

I have used  TCPIP::xxx.xxx.xxx.xxx::ddd::SOCKET that estableshes comunication...

I have also created this in Measurement and Automation and the comunication works fine.

But with this I don't know how to sen the queries, because when I use this no action is taken in the device (YOKOGAWA).

I have also tryed the TCPIP::xxx.xxx.xxx.xxx::INSTR, and this returns an error : -1073807343.

Firts I thought that was because of the port that was not specified, but I realy don't know what is the error.

From my search in the forums and the notes available by NI, I thought that I could use VISA with any of these strings:

1) GPIB::1::1::INSTR

2) TCPIP::xxx.xxx.xxx.xxx::ddd::SOCKET

3) TCPIP::xxx.xxx.xxx.xxx::INSTR

and the result is:

1) OK

2) Comunication OK but no action on the device

3) Error

Can you please advise me?

Thank you.

Best regards,

Hugo

Hi,

Can you get a communication with your device using VISA Test Panels under MAX?

 If the device is configured in MAX, you can use the device name visible under VISA TCP/IP Resources in MAX.

Hi,

If I use the instructions below, I can communicate VISA Test Panels under MAX

GPIB::1::1::INSTR

TCPIP::xxx.xxx.xxx.xxx::ddd::SOCKE

But if I use TCPIP::xxx.xxx.xxx.xxx::INSTRI can't comunicate with Max.
