Sequence Not Starting

[meerooo80]

We are using the sequence below to log a TOC analyzer to DAQFactory. However, it is giving me an 'uncaught error' in line 4.

 

device.TOCOutput.purge()

while(1)

   try

      private string datain = device.TOCOutput.ReadUntil(13)

 

      // Modifying string for IC

      private string vIC = delete(datain,1,32)

      vIC = delete(vIC,5,17)

 

      //Modifying string for TC

      private string vTC = delete(datain,1,36)

      vTC = delete(vTC,5,13)

 

      //Modifying string for TOC

      private string vTOC = delete(datain,1,27)

      vTOC = delete(vTOC,5,22)

      delay(1)

endwhile

The sequence doesn't compile because you have a try but no catch.  The indenting should give that away.  At the end you skip back 6 spaces instead of 3 to the endwhile which tells you you missed something.

[meerooo80]

Oh thanks, it works now however I do not get the correct numbers because my guess I should manipulate this code for a serial connection since it was written for an ethernet connection?

[AzeoTech]

DAQFactory treats serial and ethernet the same.  If you are getting the wrong numbers, you are probably parsing the data incorrectly.

[meerooo80]

yeah exactly, I am not sure how to do that!

[AzeoTech]

I'd need to know more about the format of the data stream to help you.

[meerooo80]

How do I get the string from the Command Monitor?

[AzeoTech]

What do you mean?  Do you mean copy it to the clipboard?  Select and right click and pick "Copy"

[meerooo80]

No I mean how do I get DAQFactory to generate the string on Comm Monitor?

[AzeoTech]

What string?  If you want to output something, type it in the area at the top of the comm monitor and hit enter.  In order to use the comm monitor, you have to right click and select the desired port.

Here you are:

 

Rx (16:16:38.243): \084\117\114\098\111\044\049\048\032\074\085\078\032\050\048\049\052\044\049\054\058\049\053\058\052\049\044\049\053\049\044\050\051\052\044\051\056\053\044\050\046\048\044\050\046\048\044\078\047\065\013\010

[AzeoTech]

Can you please repost with the "Display all ASCII chars as Codes" unchecked?  Its obvious from those numbers that you have an ASCII string, not a binary protocol, and having that checked gives us binary numbers.

Here you are:

 

Rx (15:03:16.220): Turbo,11 JUN 2014,15:02:31,-2.45,151,149,2.0,2.0,N/A\013\010

[AzeoTech]

OK, delete() is not the function you want.  You want parse.  I don't know which number is which, but, for example, to extract the -2.45 you'd do:

 

vIC = parse(datain, 3, ",")

 

for the 151 just change the 3 to a 4, etc.

[meerooo80]

So I am using the following right now but not yet creating a logging file on the computer.

 

device.TOC.purge()

while(1)

   try

      

      // Modifying string for IC

      vIC = parse(datain,4,",")

 

      //Modifying string for TC

      vTC = parse(datain,5,",")

 

      //Modifying string for TOC

      vTOC = parse(datain,3,",")

      

//Adds Channels for each output

      IC.AddValue(StrToDouble(vIC))

      TC.AddValue(StrToDouble(vTC))

      TOC.AddValue(StrToDouble(vTOC))

   catch()

      ? strLastError

      delay(0.01)

   endcatch

endwhile

 

while(1) 

   logging.TOC.strFileName = "c:\DAQFactoryData\TOCOutput.csv_" + formatdatetime("%m.%d.%y",systime()) + ".csv" 

   delay(1) 

endwhile

[AzeoTech]

Does the channel show the proper data?

 

If so, then is the logging set running and does it include those channels?

[meerooo80]

Yes the channel is showing the proper data.

 

The logging sequence is running and it does include the three channels for IC, TC and TOC.

[AzeoTech]

Try just deleting the logging set and creating a new one.  Its possible you changed one of the settings that is causing it to appear not working.  By creating a new logging set you'll get the defaults which work.  Alternatively you can post your .ctl file.
