Hi drek,

 

a table is a "2D array of strings" in LabVIEW. You don't create such a 2D array of strings in your whole VI…

 

- Create such an array and keep it in a shift register.

- Replace the elements you like to write to with the strings you receive.

 

More hints:

- Don't use BytesAtPort with serial communication. It is (nearly) everytime the wrong command…

- Right now you try to set element [0, 1] in your table with either a numeric value or an empty string. Do you really want to delete the element when "Set Value" is FALSE?

 

We talked about creating tables in your other thread. I thought you already know how to build up arrays/tables…

Best regards,
GerdW

Hi drek,

 

like this:

Initialize the array and replace the elements as needed. Then display the array in your table…

Hi drek,

 

in the Array functions palette. It's named ReplaceArraySubset…

 

(Didn't we talk about replacing array elements before?)

Best regards,
GerdW

You need to find Replace Array Subset.  It is in the top-middle of the Array palette.
