Write to spreadsheet command limits 20 columns

[cgy5002]

Hello,

I am using LabView 8.5, and an SCXI-USB for data collection. 

I am working on a program that reads in four temperature channels and 20 voltage channels using two seperate loops, then I concantenate the two signals in order to write the data to a spreadsheet file with length 24 columns.

However, LabView is cutting my data up; it will post the four temperature data points followed by 16 zeros, and the next line will be my 20 voltage readings.

Is there a limit to the number of columns that can be written to a spreadsheet via LabView, or is there another issue here I do not know about?

No, there are no limitations. You are concantanating the arrays incorrectly. You should be getting a 1D array out of your Build Array function and you probably did not right click on it and check 'Concantanate Inputs'.
