• Error 85 has occurred at the level of analysis of chain (arg4)

  I am trying to scan in hexadecimal numbers and convert decimal values to a text file.

  The file that I'm scanning consists of linessuch as

  DSDS = 00002B5D S1 S0 = 00002AD5 S2 = S3 = S4 00000003 S5 = D2BF3769 00001050 = 00001C9E

  I'm trying to convert decimal values S0, S1, S2, S3, S4 AND S5. But I get "85 error analysis of chain (arg4)". I don't know what I'm missing here. I have attached the vi below.

  
  

• Analysis of chain to get the Timestamp, LV 2012 problem

  I have a VI I wrote in 2013 LV where it works very well.  But with the same VI in LV 2012SP1, analysis of string to get a Timestamp does not work.  Attached is the VI recorded in LV2012 SP1.

  Background:

  I work with an FPGA where I am synchronizing pulses using the clock of 40 MHz.  I connect these impulses in a file on my host PXI. To correlate the clock on the FPGA with a log file and real life someday, I named the file with a timestamp, and the meter 64-bit encoded hexadecimal string.  Now, I have a pretty good correlation between when the 64-bit against him and the time of day to facilitate the search of the data file.

  Now, I try to analyse the file name, so in my analysis of code I can reassociate the value 64 bits with the time of day using the string functions to separate the file name.  With a few regexes (which I've never used in real life before), I've broken down the chain and got the base time as a timestamp, and the counter value as a 64-bit integer.  The VI works very well in 2013 LV.

  But when I saved it to the LV 2012, analysis of string to get the timestamp fails.  No error, but the timestamp shows 19:00 12/31/1599 (I am GMT - 5).  I have no idea why.  A bug in the parsing of the string that was set in 2013 LV?

  Please run the attached VI in LV 2012.  Confirm if it fails for you.  Then open it in 2013 LV and see if it works for you.

  I am trying to make it work in LV 2012 because this project is locked in this version of LV for now.  I can probably do something to reorganize the time string to get something that will scan a digital time stamp if I have to.

  Hi Bill,

  Sorry to be a bit late on this point, I just came across this thread after the hunt for the CAR for a separate issue. The fix for 300375 CAR is what causes the difference in behavior between versions of LabVIEW. It appears on the list of known issues of LabVIEW 2013, although the description focuses more on the fixed number than other possible differences between the versions.

  The thoughts in this thread died on what happened in the difficulty. LabVIEW 2013 now pick up the string of year 2 or 4-digit number when you use the %y or %Y tags, respectively. Previously, the behavior was more forgiving in the year format, leading to incorrect behavior that you have observed strings of 4 digits in the year the %y tag. The original problem, you pointed out (2012 incorrectly string manipulation of tagged %y (2 digits) 2-digit year is precisely what has been fixed in the CAR.

  Regarding your strange result over the years with the tag %Y-2 digit, this is a limitation of the type of data Time Stamp itself. The year will always be converted to between 1600 and 3000. So no time extreme travel journaling. Yet.

  See you soon,.

• Analysis of chain for the chips to generate errors

  Hello!

  I program who receive channels of the ports series, split into 2 separate strings and write in separate tables. Everything is fine, but sometimes Scan string for chips generates strange values.

  For example: if I send strings like this:

  23.14 67.00

  23.18 68.00

  23.18 66.00

  and after the separation, I'm getting values such as:

  23.14, 8, 23.18

  67.00, 0, 66.00

  It sometimes seems that last figure is increased.

  Here's my VI

  (data in "serial port" are correct)

  

  And output values:

  

  I guess it might be something with delays, because if I'm reducing the time of waiting inside the loop, the errors appear more often. If so, are there any other (quicker) way to split a string into two? I already checked search/Split string with offset adjustment, but it did not help.

  (I use LV2010)

  Yep, use the termination character.  I was in a hurry so don't quite understand why.

• Analysis of chain incompatible jacquard

  I need to analyze a name string that contains: surname, name, first name (optional) and suffix (optional). Like this:

  You might consider doing a real table of possible suffixes.

  Where there is a comma, it can be any number of spaces before or after the comma.

  Since you have Oracle 11, I used version Oracle 11 of REGEXP_SUBSTR, with 6 arguments. If someone wants to do something like this in 10 Orace, use REGEXP_REPLACE instead of REGEXP_SUBSTR.

  First name is assumed to be a single word (i.e. any combination of characters except spaces). If there are 2 or more words after the comma (last), then all but the first part of the middle_name, until the release of your sample data is:

  LAST_NAME  FIRST_NAME MIDDLE_NAME  SUF
  ---------- ---------- ------------ ---

  ROLLINS    JOE        ALAN

• search string and convert whole real or 8-bit 32 bit

  I was hoping to get some advice on how I could search for the following string and convert it to a real number or an integer.  The following data is output as a device ascii characters and I would look for both in each line (starting with 7699,72 seconds in this case) and convert each one to a real number.  Furthermore, I would like to get the integer values in each row (0, but could be 1,2,10,12, etc.) and convert them to an 8-bit integer.  I think that using the template Match followed by analysis of chain would screw that I need, but am not sure how to match in each case. Thank you!!

  What are the characters in the white space between the and the numbers?

  Scan chain can probably not what you want.  Note that in the image space characters include spaces, return carriage, line breaks and tabs.

• String to number conversion problem

  I have a VI that pulls in data from a device using VISA, and I got it on another computer to work a few weeks back. I had to transfer the VI to a laptop computer to run a few tests, and now I can't make it work. I am unable to put my VI because the laptop on it's is unable to access the network companies, I will do my best to explain it all, I apologize for the inconvenience! My problem is not however with VISA, it's with an exit VISA number conversion chain.

  I have attached a painting drawing of VI to better explain it.

  I use the block series Visa football match in baud rate and all that many good things to the unit and port settings set of device management. Then, a while loop is entered. The loop will run until you press the stop"" button. The next block of visa is the writing block, he asks for a reading of the device. The next block of visa is the first block of reading, he returns playback in the form of "NA-XXX. X' where x are numbers. The next block of visa is the second reading block, this block just echoes back the command sent to the device. Playback of the first visa read block, "NA-XXX. X' is going exponential/fractional chain to digital converter.

  When you perform a run/debug to highlight run, the release of visa reports the correct value, is the value of the device reading - however the string to number converter generates a 0,000, no matter what channel number is. I am at a loss as to what may be wrong because it's the EXACT set up I had to work very well a few weeks ago!

  I'm using Labview 10 on the laptop, the old computer was labview 7. I'm guessing that this is perhaps the rub... I Redid the VI from scratch, although I have not opened the old VI in labview 10.

  Any help would be appreciated. Again, sorry I am unable to attach the VI.

  Would it not have been easier to just post a screenshot? You might also have used the Tool of Capture of Code. (Which reminds me that I need to install it to my previous versions of LabVIEW, as evidenced by the screenshot I took. )

  As to the question: you probably either:

  • employee analysis of chain initially and when you rewrote the VI you used the regular string conversion functions.
  • Wired an offset value in the string to the number function.

  

• Basic visa write and read the example

  I use basic visa read and write example to control my temperature controller in fact it works perfectly, but I want something else. First of all, I like to read the value of continuous temperature and it can be read on the read string section but I want to do but digital indicator to see the temperature value is it possible? And what is the function I should use for this? In fact I used the analysis of chain to do but I have not checked but it works or not?

  Second, I have to set temperature sometimes on the controller actually I can do writing tset = 025,0 to set the temperature F 25, it works when I write this command in the Panel (string to write), but I want to do like DIGITAL controller or something like that instead of writing the command for each setting is possible. I want to increase or decrease the temperature by pushing the increase or decrease button instead of write tset = 0.250 / a. could you help me with this?

  Thirdly, I want to run some parts of the program permanently a part when I want to run, as possible, now I have while loop and my example works permanently. I want because when I set the temperature which must not operate continuously, because it is a time command to read the temperature value this section runs continuously as the temperature on the experimental set-up is changing one I have to see this change, for example I set temperature 100 F and the peripheral controller 100 F heat , but this order is an order of time, but read temperature command should run continuously because the temperature is changing and I need to read the temperature for every 60 seconds and I can be a part.

  

  Make sure that you concatenate text constants "code view".

• Interact with a CGI web page

  Greetings OR Forums,

  I am developing a telescope pointing control system that needs data ephemerides generated from a Jet Propulsion Laboratory web site:

  http://SSD.jpl.NASA.gov/horizons.cgi

  The main interface of their horizons system is via Telnet which is precarious and is no longer supported by LabVIEW.  I was hoping that someone could advise me on how to start using LabVIEW to interact with the web page of cgi based at the above address.  If I can do it, I can retrieve the necessary ephemeris data and analyze inside LabVIEW using the commands of the base string.

  Is there a kit of basic tools that you can point me to interact with web pages or any code sample?

  Thank you
  Scott

  Use screws of HTTP Client:

  

  VI GET is the standard demand 'give me this web page' - give it the URL of your ephemeris data session and the release of 'body' will give you the web page content - if you use the raw text of output, then this should make analysis easier chain (without tags html etc..).

  (In addition, you can use Telnet in LabVIEW, it is not a library group for her more - you should be able to use the TCP screws to roll and you can also if interface with other libraries/applications Telnet for example PuTTy... it might even be something in .NET)

• Based reading Serial and example of writing used in a graph

  Reading and writing labview example I get responses like '250 v' and "v 3000".  How to make just the "250" and "3000", as the right type of data, put in a table or a chart?  All opinions are appreciated.  Thank you!

  Best solution is probably to use an instrument for any device driver you contact.

  The other method would be a simple analysis of chain.

  

• drawing table 1 d of time vs channel

  Hello

  I want to draw the hour data (table format - string 1) vs. The time should be the time where playback is recorded (not seconds), I want to say I can record an array of time data in the similar to the current loop being saved to a file or even a plot of real time will do.

  Thank you

  You will need to find time with the get time in seconds and also convert your string read a digital (e.g. analysis of chain). You can use a table inside the loop as long as you do not change the timewhile wait the because the loop runs. Look at the example Char real-time call.

  You have other problems. Do not use the insert into the Array. In fact, the use of the shift register is completely useless. Just the data out of the loop of the wire. Your entries in the loop are not wired for the shift register and the shift register is not connected to the write VISA function.

• Installation of RHEL 6.5 kit HIT

  I "m trying to do an installation of the kit Linux HIT (1.2.0) on a server of RHEL6 fully updated (patch level 6.5). While the HIT kit installed, I "m having problems with the demon ehcmd crash on startup, due to a non supported ' iscsiadm - version ' revision.

• Number of evil which used chain analysis

  Hello

  I know there are a lot of discussions about string to a number. But none would really help me.

  I use 'analysis of the chain' in my vi for a number. Noramlly which still works, but I have a problem, this time.

  As you can see on the hands of the attached picture 'analysis of string' wrong number.

  Prob 45 shows a string with the 30th 30.0300 + 3 but after analysis of the chain is just a 2. What I am doing wrong?

  Thank you for your help

  It's to find the 2 in Chan2.
