Error 85 occurred at Scan From String

[Sena_Scott]

Hi,

      Below is my attached Vi.. Its was kind of working randomly, cause the timing of this error "Error 85 occurred at Scan From String (arg1)" Pops out randomly. Hope someone can tell me roughly where is my mistake.. Thanks...

Hi Sena,

this error pops up, when:
- you provide "wrong" data for your scan string
- you don't wire the error cluster coming from ScanFromString - as you should do when you aren't sure your string data has always the same format...

I'm getting the same error and I'm not sure why. I've attached my VI

In your code, the function 'Scan From String' expects a string input that contains data in some specific (numeric) format.

If its not the case, it gonna throw this error (85).

You need to include additional code to handle this error in your program. While running your program, keep a probe at this input wire (string) and observe the data whenever you get this error (85).

Do you know what kind of code I would add?

[priyadamico]

I'm actually trying to read the data through a DAQ but I'm not sure how to write that into a VISA function. I'm not sure if this code makes sense or not

[moderator1983]

When you're reading from DAQ card (device) then what is the purpose of Serial communicaiton.

Also in your code:

The circled node (function block) makes no sense and on execution, this code will definitely throw an error... reason being, the task is configured for Analog Input and cannot be used for Analog Out...!!

[priyadamico]

The reason I'm using both serial and daq communication is because i need to communicate through serial to give the device commands but i'm reading data through the daq. I cannot issue commands through the daq 

[priyadamico]

It has not given me an error yet though...

I took out the VI you circled and the code seems to be working
