indicator control

[Mathan]

Dear all,

Let's confine to another query regarding indicators and write to text file.

I have 4 indicators (2 arrays and 2 integers) and i need to write these values to a text file till the program stops. I used "build array" to convert all these 4 values to a 1D array and gave as input to the writetospreadsheetfile.vi

But the output in the file was in decimal values and actually my indicators will show hexadecimal values.

How to achieve hexadecimal values to be written in the text file as such the indicator is displaying?

Thanks,

Mathan

I concur that variables are indeed a powerfull tool. But since LabVIEW variables behave different from variables known through textual ADEs, they are the most misused tool ever in LV i asume....
And that is, why they are evil......
I have to confess that i use variables myself from time to time, but i always double check for possible race conditions and even then have some kind of bad feeling in using them. And that is, what i try to achieve: That everyone programming in LV gets the same "sensibility" as i have regarding variables!

Dear mike,

I studied the use of arraytospreadsheetstring function from your example.

I need the output in the text file like this format. How it was possible?

Date,Time                 name1(constant)                   indicator value1 (in hex)
Date,Time                 name2(Constant)                  indicator value2 (in hex)

Example:

   -   Doctor        3B,6D,14,23.....(Like this) some 17 values

   -   Patient       12,43,ac,f7.....(Like this) some 17 values

   -   Doctor        3B,6D,14,23.....(Like this) some 17 values

   -   Patient       12,43,ac,f7.....(Like this) some 17 values

   -   Doctor        3B,6D,14,23.....(Like this) some 17 values

   -   Patient       12,43,ac,f7.....(Like this) some 17 values

Thanks,

Mathan

Dear mike,

That quick example shows ur in depth knowledge. Thanks.

But still i had two problems.

1) I need to insert the current system date and time in the first column of each line as i mentioned in my previous post.

Date,Time                 Doctor(constant)                   indicator value1 (in hex)
Date,Time                 Patient(Constant)                  indicator value2 (in hex)

2) Everytime the values are getting overwritten in the text file rather than get appending. (Am using a while loop outside and i stops the vi after some particular iterations).

Please update me asap. Look at my attachment.

Thanks,

Mathan

I wish they would include your statement in Labview courses and within the on-line tutorials.  But then again, how many people actually take the time to study the language 😞

Dear mike,

I worked it out fine. So much thanks and stars for you.

P.S. I used this for date/time

Thanks,

Mathan

Mike,

You can directly wire the HEX array to the Number to Hexadecimal String converter, no need for FOR loop.
