connect to Agilent 34410A via Ehternet cable and VISA interface

Hi,

 

I have a question regarding setting up the "VISA reference source" with an IP to collect the readings from the Agilent 34410A!

 

I just downloaded the driver via NI side for that multimeter:

https://www.keysight.com/de/de/lib/software-detail/driver/34410a-34411a-digital-multimeter-labview-i...

 

Unfortunatelly the code using the VISA interface instead of the TCP VIs in labview. But using the text "TCPIP0::[IP Adress]" I get contact with the multimeter and my code does collect the data as wanted! For information: I use a labtop with NI 2020 installed and I tested all first running the VI itself and also as builded application. But the labtop has only ONE ethernet card on board!

 

Now I wanted to use the builded application on another computer in our measurement room that has THREE ehternet card included .. and here I am not able to set up the VISA interface!

In the Labview help it is stated, that the "0" is the indentifier for the used ethernet card. So I tired "TCPIP1 .." and "TCPIP2 .." etc, but without any success.

 

Does anyone has expierence with using TCP/IP via VISA and with more than one networks inlcuded to the system?

 

Many thanks and best regards

Thomas

Are the VISA drivers installed on the other host computer?

Granted I have not used that exact instrument but... I have used VX11 (Ethernet) based instruments with VISA on systems with both an Ethernet and Wi-Fi adaptor

 

A VISA resource string for an IP based instrument should look something like this TCPIP0::192.168.0.7::inst0::INSTR

 

One thing that might help is to put your instruments on a separate subnet then your LAN (or Wi-Fi in my case) 

 

LAN 192.168.0.xxx 

Wi-Fi 192.168.1.xxx

 

The Windows routing tables should then route the IP traffic to the proper network adaptor.

Many thanks for your comments!

 

I just attached a picture in how I set the VISA reference .. and it worked on the used labtop pretty well! I did not post the whole code as that doesn't matter

However - I will follow the hint from "P27" and will install the drivers on that "other" machine. Maybe that helps.

 

@RTSLVU

All three network cards using a different subnet: So the mulitmeter is in the subnet 192.168.150.xxx and the others are like "192.168.151.xxx" etc! Including the laptop to that network everythinks works well! But just on the other machine (that is always a part of that network) it does not work. But maybe the installing of the VISA drivers will help.

 

Many thanks and best regards

(Facepalm) Um....Yeah you have to install VISA for any program that uses VISA to work!
