Analysis of the chain: entry Boolean

• What is the analysis of the chain model for "fits all"?

  Hello

  Using scan chain for a while, I know that %s corresponds only to chain up to white space. And I also thought % [^] matches everything, including spaces. But it turns out that it stops at the closing brace square.

  So what's the real scan pattern match everything including spaces?

  Want you that the Scan of chain at the end on?  Or are you typing just the rest of the chain?  If this is your scenario, then simply use the output 'remaining chain.  It might be useful to give a complete example of a normal input string and all WHAT you want as output.

• Analysis of the chain, insert. in a string

  HelloW LV'ers

  Simplified example

  I have a string with 3 digits for example of entry of 789

  I would like to use scan string to place a "." between the numbers.

  entry exit 789 7.8.9

  How to configure the scan station to do this?

  Thank you

  Of course, a general solution must be scalable. I don't think we can assume that there are always exactly three numbers, because it has been given only as a "simplified example.

  Here's a solution that works for any length string (containing numbers decimal only)

  

  (of course you must ensure that the entry is healthy and that it does not contain any characters illegal. not shown, but look at lexical class)

• ANALYSIS OF the CHAIN fails with empty quoted strings

  I'm scanning a long text with the STRING SCAN line.

  

  "[My problem in the first place of this part: " [^] "]"

  The string I'm scanning a quotes in it - I want to extract the string in quotes as a single item.

  I can't use %s because the string can have spaces that it contains.

  The format string works fine except if the quoted string is empty ("").

  "[I interpret " [^] "]" a number of things that are not a QUOTE, QUOTE, QUOTES.

  Apparently, 'any number' does not include zero, as it fails (error 85: data not matching format) when the quotes are empty.

  What Miss me?

  This confusion arises as well in RegExes, but you hit on the answer: in the Simpsons "Zero is one percent", but in the analysis of String Nothing is not something.  You asked to match something that's not a quote, and there is nothing here that is not a quote, so it complains.

  In this situation if I really wanted to keep the convenience of analysis of string I would generally use Search & Replace to replace "" with "\00" before scan and then process a string that only contains null as empty.

• analysis of the chain of the serial port to retrieve data

  Hi all

  It is a problem of beginner. I have two sensors sending data to a same wireless serial port. In order to distinguish which is which. I coded each sensor to send data with a unique address UoL 000 X, then followed by two values, I want to read. These two values are in the float with format fixed impression (decimal fixed after the third bit). The format string of the first sensor should looks like UoL 0001 123,45678 876.54321. I use the Scan of the String function, unfortunately, it doesn't work that way. Could you please check the VI for me? Or a better solution for this application. Thank you very much.

  S.G

  It does not because what you have set is not different from what you have joined earlier.  Have you tried something?

  See this amendment attached to your VI.  The format strings work with the examples you gave, and sends the data to the appropriate indicator.

  Also, I cleaned up the mess that the inner loop where you were waiting for 1 or more bytes.  Which means most of the time that you would probably get an incomplete message.

• Numerical analysis of the chain of extended precision

  I'm looking for a way to parse a string to an extended precision floating point digital. The Conversion of Numer/string "Scan value" built-in LabVIEW 2013 function returns a double. How can I get a JOB?

• analysis of the chain

  Hello

  I want to display values that I'm playing an instrument via a serial port to a xy graph based on the real time... But I do not know why it shows only the last value not drawing the entire curve.

  

  the program is attached

  any suggestions?

  It seems that your problem is your line at the moment.  You are dividing by an array with 1 element.  Therefore, you will have only 1 value of X.  Instead, divide by a digital scaler and this divider will apply to each element of the array.

  But a better way is to calculate once per iteration, only (instead of the item once to always each iteration).

  

• Is there a way to parse a string containing % (percentage symbols) using the function 'analysis of the chain?

  I am communication in series with a mirror device and the syntax of the input string contains this text: "% hr ="

  I was not able to find a way to say to the function that the percentage here is not a format specifier. Is it possible, or should I just try to use a different function?

  Thank you.

  Use %% in your format string for what he knows to use the percent literally.  So % RH = %f

  

  EDIT: Darin has one here in front of me.  It seems to be-% and % both work.

• analysis of the chain does not recognize the AM/PM indicator

• The good examples of the construction and analysis of the data in bytes?

  Hi all

  Very soon, I'll have to find a way to build messages to bytes to send to a serial port and a serial port to receive and review to the basis of events out of...

  However, before I delve into the complexities of the serial port communication and VISA, etc... I would just like to see some examples of working mainly with data of bytes.

  I found how to get a digital constant the byte value... the binary representations signed and unsigned, etc..

  However, if I could find a simple example or tutorial just to see how to assemble the byte-code... and how to analyze it, it would prove invaluable for me to study.  I've never really worked at the byte level / binary front... and a few examples with LV would be very practical.

  Anyone know of any good links out there something like this?

  I'll eventually be sending 5 bytes out I need to build... and will receive 9 bytes in, each of which I need to parse out and respond...

  Links or information GREATLY appreciated.  I'm pretty decent analysis of the chains, real expressions, etc... but never worked with the construction and analysis of the data in bytes.

  Thank you in advance,

  Cayenne

  If you are comfortable with binary data, you can use the Boolean charts. Look at the number of table Boolean and array Boolean functions numbers. Instead of masking with an AND, you can easy to use array index to check a bit particular.

• The analysis of the non-numeric characters in a string

  Hello

  I am communicating a robot to LabVIEW (2013) via TCP/IP and sockets. The robot is the server, and LV is the customer.

  I start with the target data in this format (in a string):

  "[0 ~ 100 ~ 0] ~ [0.96593 ~-0.25882 ~ 0 ~ 0] ~ [1 ~ 0 ~ 0 ~ 0] ~ [150 ~ 50]."

  [X, Y, Z], [Q1, Q2, Q3, Q4], [C1, C4, C6, Cx], [TCPVel, OrientVel] except replacement ',' (comma) with a ' ~ ' (tilde) because I load the target data in a spreadsheet which is a comma-delimited file.

  In LV, I take this string, the analysis of the chain and split individual items. I then pulled the singular elements as unique, 32-bit of real numbers. I take each one and convert them individually to a string, concatenate them and send them to the robot. The robot decompresses these raw bytes individually and converts them to a target of robot (position in space).

  I train (BT) check if the user has sent a bad character (non-digital) in the target data. Example of this is:

  [- 50 ~-150 ~ 0] ~ [0.96593 ~-0 ] [B2has5D882 ~ 0 ~ 0] ~ [1 ~-1 ~ 0 ~ 0] ~ [150 ~ 50]

  Now in BT, when I'm scanning the chain, these bad character becomes the entire element to zero and everything else then to zero as well. See attachment for example screen similar.

  My question is, my VI, I can analyze all non-numeric characters (that are inside the parentheses and characters that are NOT a ' ~ ' (tilde))? In this way, I can always get this item numbers and do not have this element or other items turn to zero?

  Thanks in advance for any help!

  Sorry for the question of the test

• Analysis of the error in normal mode string

  Hi all

  Suddenly, my analysis of the chain has stopped working and started giving me this error. The read string ends up being something like 2.86E - 4 or similar. When I run mode highlighted everything works fine and it interprets the number very well but when he's not in highlight mode it returns an error. Not sure why since it is just a number to convert. Any help? I have attached the error and the highlight mode version. Thank you!

  First guess: synchronization problem. Especially since you said it works in highlight mode. Specifically, when you run culminating point mode you expect probably not long enough before trying to read, and the loop will immediately detect any byte on serial port. This delay function there will not guarantee a delay of 1 second between writing and reading. There is no dependence on the data - a rookie mistake. Use an image sequence or time to late VI to have clusters of error wiring through establishing the data dependence.

• Switching between the two entries of automatic chain

  Hi guys, I have several entries of chain on the front panel, which everyone should take an entry of a code scanner barcode.

  What I want to do VI meet is, jump to the next string available, entry, once one of the string entry receives an entry of the barcode scanner. (as shown in the transition between the photo 1 and photo 2).

  Is this possible?

  See you soon!

  You can use a structure of the event with a value change event. When the value of the control changes, which means that you scanned, you can set the focus to the control, depending on whether you want to enter your data analysis.

• Using a control of the chain with the Enter key, return * and * allowing repeated identical entry

  Hi all

  There must be a simple solution for this, but it's Friday afternoon, and my brain is not cooperating.

  I create a simple terminal through which a user can interact with an instrument. My question is about the only query string control. The button send and the Terminal Table are here for reference.

  

  Here is my desired behavior:

  (a) the user types a command in the field of the query, tape input or return. An event is triggered, and the request is sent to the instrument. The focus remains on the field in the query.

  (b) with any other action the interface user, the user types Enter or return again and again, by triggering an event that sends the request to the instrument every time Enter or return is typed. The focus remains on the field in the query.

  Here's what I have:

  

  This allows for one), but fails to b). The reason is, because the value of the field in the query has not changed, change value event does not fire when the user starts to spam keys enter or return. There is a way around this, as suggested by this post. Here is the solution in a few words:

  

  Instead of looking for the change in the value of the query command, the event fires for each key event to the bottom of the control and resembles a pressure of enter key or return. What attracts the user action, even if the content of the field of the request have not changed. The problem with this approach is that, when this event fires, I need to read the value of the query string order and send it to the instrument, but the value I get via the local Variable query is the old value, probably because the key down event fires before the value of query is saved as changed. Is there a way to programatically "enter" the contents of the control channel so it is recorded as a change in value, until I have the question via a local Variable? Is there a different way I should go about it? I'd rather not do anything that bound the input keys or return to this particular area, since I have many other UI elements that need these keys in my program.

  If not, is there a way to make the control of the fire 'Change of value' query string event when the user presses enter or return even if the value has not changed?

  Thank you for your comments!

  I thought about it.

  (1) control of the string (query) a value of update while typing.

  (2) save the key event down to the control of the chain. If the entry or return was pressed, send the state machine to the State 'send request '.

  

  (3) in the application 'send' State read control channel via the local Variable value.

  

  This is the desired behavior to allow the user repeatedly hit entry or return to regularly send a command, and the user can also type in a new order and send it by pressing enter or return.

  Thanks to all who have helped me this something to think about!

• The analysis of the Variables of e/s channel properties

  I have a situation in which I would like to configure the Daq on a cRIO since an interface of configuration on a Windows host. In particular, I would like to get IO addresses Variable for all analytical engine channels configured on the cRIO. The Setup program runs on the Windows host and impossible to deploy any demon on the RT which could question the material. He needs run as if the cRIO is not present.

  The configuration program is part of the same project as the cRIO, so my thought was to analyse the project to find corresponding topics. Here's a post that does something very similar:

  https://decibel.NI.com/content/docs/doc-16630

  However, this has several problems. This example was written in 2011. I am using 2015. Apparently, the properties have changed since then. Children' find' (it is no longer named "children []") does not give me the chassis on my 9068 reference. Instead, I could use the property "Items Owned []", which gives a bunch of things, and then I search the TypeString of these things until I have find one that is "Chassis". Fair enough. Then the ref chassis gives me the Modules and the Modules of give me the channels. Seems pretty good. But all I get are the names of channel. I can't find all the properties that define the type of module or the direction of IO. For example, I would like to know if a variable is a Boolean or real, and if it is a path of entry or exit. You can deduct that the names 'standards', if the project has not been changed to allow giving them a meaningful name to create or. But it looks like there should be a way to find these properties directly.

  Any ideas?

  TIA,

  DaveT

  I think that the analysis of the project tree is a quite fragile strategy that you should know already. AFAIK the OR sanctioned for this sort of thing for a few years now is to use the API of the System Configuration. Yes, it's a pretty involved API and need you a little time to learn how to get the specific information you are interested in. Fortunately there are some examples that you can use to start with.
