I was thinking of getting 8 data rows for 8 different channels which will runs with 8 specific command 😅.

Read the manual of your device!

When it only offers the WF8readall command then you need to use exactly that command.

When it offers a command to read specific channels then you should use that…

Yes I know that.  But how do I arrange or which function do I use in labview to do that 8 rows or send specific command to do that 8 rows? I think, I can’t just use just 1 visa write function to write 8 different commands  to 8 different row. And which function to use to make 8 rows and send 8 different commands continuously.

Sure you can use just one VISAWrite to send different commands! Just use a loop to iterate over an array of commands!

Additionally your loop will also create an array of responses just by employing autoindexing!

This is very basic LabVIEW stuff: it seems you should take those "Training resources" offered at the top of the LabVIEW board!

Ok thanks. I will check and let’s see how does it go. I am currently stuck in sending ASCII to the device but the device is not responding. I tried send command using visa write. But no response from the device. Am I doing something wrong?

The answer is "Probably yes!"…

As you didn't show your VI we cannot tell you, if and where you went wrong!

[InternlABVIEW]

I am currently using this VI to check those command to device but no luck so far. It is one of the example from Labview.

Hi Intern,

have you tried to change the TermChar, maybe to 0xD (aka CR aka \r)?

Which commands to you try to send?

[InternlABVIEW]

I tried to send command in normal window and Hexa and \n. In the manual it’s says I have to send ASCII uncoded command into to string format. 

[InternlABVIEW]

Any modifications  need to do in Visa Write to send command to device which need to be ASCII encoded command in string format to the device.

Hi,

I am currently using USB-RS232 to get data from the instrument device. However all the data are coming as a

26/07/2021 2:43 PM CH2,RTD,-1809.400

26/07/2021 2:43 PM CH3,RTD,-1809.400

26/07/2021 2:43 PM CH4,RTD,-1809.400

26/07/2021 2:43 PM CH5,pH_,0.000

26/07/2021 2:43 PM CH6,pH_,0.000

26/07/2021 2:43 PM CH7,pH_,0.000

26/07/2021 2:43 PM CH8,pH_,0.000

How do I put those data according to the channel number every time in different rows. For example, 8 channel data in 8 different rows every time.

The code, I am currently using as follows.
