My data format is: 
T, 2021,04,02,15,03,23\013

 I can see the data comming inthe comm monitor but I am getting error:  C1000 Channel or function not found: Line 7 

The code I have written to parse this data is:

global String datain

device.Neph.Purge()

While(1)
 
try
   
datain = device.Neph.ReadUntil(13)

switch
   case(left(datain,1) == "T")

      Yr.AddValue(StrToDouble(Parse(datain,1,",")))
      MM.AddValue(StrToDouble(Parse(datain,2,",")))
      DD.AddValue(StrToDouble(Parse(datain,3,",")))
     
      HH.AddValue(StrToDouble(Parse(datain,4,",")))
      MN.AddValue(StrToDouble(Parse(datain,5,",")))
      SS.AddValue(StrToDouble(Parse(datain,6,",")))
     
     
    endcase
   
    catch()
  
    endcatch
   
   
     

EndWhile

What could be the possible error?

Thanks!

FYI, when I change the channel I/O type to special, the data started parsing but the output is not a correct 32-bit floating number. 

The settings of my channel are set to:

channel name: myChannel1

device type: test

D#: 0

I/O type: Special

I am not getting the correct values. Is there something I am missing?

P.S. I am Sujan from Baylor and have been working with Jimmy and Sergio from the UH as well to make it work. 

Hi Guru,

When I run the sequence (in an earlier post), I do not get any error message but neither the hexadecimal part of the data line gets parsed into the channels. When I run the code for query (like ? "myChannel" + c + ".addValue(floatValue)" or ? floatValue ) in the Comm Monitor, I get the error message saying "C1000 Channel or function not available".

Sorry for the typo here. But the addition of parenthesis is not helping.

I have been relying on you a lot to solve this issue and thanks for being so helpful so far.

Here is the complete code:

global String datain 

device.TapB.Purge()

While(1)
  
try 
   
datain = device.TapB.ReadUntil(13)

      Record_type.AddValue(StrToDouble(Parse(datain,0,","))) //This is parsing properly
      Active_spot.AddValue(StrToDouble(Parse(datain,4,","))) //This is parsing properly
      Flow_rate.AddValue(StrToDouble(Parse(datain,5,","))) //This is parsing properly
      Sample_volume_active_spot.AddValue(StrToDouble(Parse(datain,6,","))) //This is parsing properly
      Case_T.AddValue(StrToDouble(Parse(datain,7,","))) //This is parsing properly
      Sample_air_T.AddValue(StrToDouble(Parse(datain,8,","))) //This is parsing properly
      
      for (private c = 0, c < 40,c++)
         for (private i = 0, i < 4, i++)
           fdata = evaluate ("0x" + mid (datain, 62+c*10+i*2,2)
          endfor
        private floatValue = to.rwFloat(fdata)
        execute ("myChannel" + c + ".addValue(floatValue)")
      endfor
      

    delay(1)
    catch()
    endcatch      

EndWhile

? floatValue; ? "myChannel" + c + ".addValue(floatValue)"; or ? fdata would give an error message saying:

"C1000 Channel or function not available"

The problem now is that nothing is getting stuffed to the channels. Any guess why?

I tried to edit the code and run, but I am not getting the float value pursed in its channel. The other question is with the looping command you have in an earlier post, I will have to create private for every 8-dit hex individually. But I have around 40 of the 8-digit hex integers that I have to convert to a floating-point value. 

Here is an example of one of the data lines:

03, 0002, 00003ef7, 0018, 01, 1.996, 0.00142, 37.00, 34.22, c343ef6c, 48b09b55, 4834423c, 486dc150, c3423a45, 48758f3c, 48011951, 4827deac, c2bd6321, 487189bf, 47fc6640, 48213bd4, c2ab3f0d, 48756a90, 480020b0, 48250060, c2c627a3, 486fdf58, 480007a6, 4828f8c7, c2f23422, 48702856, 47f488a6, 481fa9d0, c38221db, 4883722d, 480480a7, 4830920e, c3893305, 4881ff54, 47ff16d0, 48289c3b, c3301adc, 48880fb4, 4806eb88, 4833d955, c358a903, 48a4f341, 48246cf4, 4857f0f1

(Bold datapoints are in 8 digit hex values which needs to get converted to floating point integer)

My instrument gives one dataset every second. With the individual lopping it will get really tedious. Please help me convert 8-digit hex and purge the data to its individual channel.

FYI, I have created the channel for each data point and the data points which are in the string format are getting purged. Please let me know if I can provide more information.

Thanks!

the additional command lines helped me know what actually was going on. 

I have additional questions for you.

My data line is in the form: 

03, 0002, 00003ef7, 0018, 01, 1.996, 0.00142, 37.00, 34.22, c31a0953

When I run the command:

? mid(datain, 62,8)    // I did 62 as this data is at the 62nd position including commas as space

I get: c31a0953

(This is the actual 8 digit hex that I want to convert to 32-digit floating number. So it's good until here.)

Now to do so, I ran the command:

? evaluate("0x" + mid(datain,62,8))

I get: 2147483647

However, this is not what I want. I am looking to get the 32-floating digit answer: -154.036.

Can you please help me with the syntax. 

Thanks!

Hi, 

My data column has 10 fields consisting of a combination of ASCII text, 4-digit hex and 8-digit hex numbers separated by a comma. I am trying to parse the data by am not successful. However, fixed-point decimals are getting pursed easily. 

For instance, in my data line separated by commas, the fifth data field is an 8-digit hex integer ("4857f0f1"). To purse that data I'm using the following script.

global String datain

device.Instrument1.Purse()

While (1)

try

datain = device.Instrument1.ReadUntil(13) 

Data1.AddValue(evaluate("0x"+(Mid(datain,5,9))))

delay (1)

catch(1)

endcatch

EndWhile 

Hi,

I have a very similar case as described in the labjack support section 7.2 (https://labjack.com/support/ud/df-lj-app-guide/7.2) for sending a warning email when the pressure is higher than a certain value. The only edit I need in the example code is that I want DaqFactory to send me an email when the pressure reading is above 80 for more than 10 minutes.

Thank you!!!
