• control the flow of a HPLC L - 6200A Merck - Hitachi pump

  Hello

  I'm trying to control the flow of a HPLC L - 6200 A Merck - Hitachi pump. I already found a VI in this forum in the post below:

  http://forums.NI.com/T5/LabVIEW/HPLC-pump-feedback-control/TD-p/1612428

  I put the pump switches according to the manual as I changed the pump in remote mode. Also, I adjusted my COM port settings in windows system manager according to the pump and LabView. The problem is, that the pump doesn't make any signal sent from the computer. I used "free serial port monitor" to ensure that a string is sent througt the COM port. Does anyone have an idea what could be the problem here? I would really appreciate the help. Thank you in advance,

  Greetings,

  Hey,.

  Thanks for the reply. It was in fact the indicator in the right direction. I used RealTerm trying to send a signal to the pump. Apparently, the problem was the type of string, I sent to the pump. In the discussion above, the string of space was sent as "\s", but apparently it can directly be sent as "". "" Yes, it's always the small details... In any case, thanks for your help.

• How to change the value of string clustered, to implement using the node value of property instead of writing directly on the flow of data or using the variable

  new to labview :-) and I have a problem when I want to change the value of a string in bunches, and I want to implement this using the node value of property instead of writing directly to the stream or by using the variable, enclosed is the picture.   No matter, I have change in cluster (control) or value of Popery out (indicator) cluster, the value (sensor 7) dataflow keeps unchanged even I gave the new value by value of property node. Thank you to give me some advice about this.

  

  Hi GerdW

  Thanks a lot for your answer. The reason I'm stubbornly tring to break the flow of DATA is: we have a test system that have about 100 screws, they have a few connected flow, some of them will be unbundling a cluster dataflow chain to check the value in order to make the different cases.  Now I want to insert user event by changing the control and influential cases during run time.

  As I initially uses a global variable (to control cases) instead of unbundle string data flow, it works well.  But then, I found there are a lot of screws that are using the string unbundle.  One of the 'lazy' means, I tried is to change the value via the property node (because that way, I did not need to find all the places where using the unbundle string and replace them with the global variable), then I noticed a problem with "dataflow", the value in the stream of cluster in fact will not be changed by changing the value of the property node.

  I did a test with VI simple (like the picture in last post), and after reading your advice, I tell myself that I need to understand the concept of "DATAFLOW" in labview, it seems that my "lazy" way can not work in this scenario.

  I have attached the criterion VI here, have you furthur suggestions on what I can do in this case?

  Mant thanks!

• How do the flow of text in a field to another. It cannot be a multiline field.

  I am creating an interactive form that must also be the possibility to be printed and completed manually. How can I get the text is flowed by a field with one below when two text fields are not the same width? For this reason, it cannot be a multiline field. I have attached a screenshot to illustrate my attempt to continue the flow of text in the text field text field 22 to 23. Thank you.

  

  "Not good" means that you lose at least one character during the movement of the raw material to the second, and you also cannot come back in the second field of the first when you use the BACKSPACE key.

  I would advise against trying it. If you can, re-design the form so that the two lines start at the same position and then use a multiline field. If you are unable to do this, simply leave the fields being independent of each other. The user will be able to tab between them.

• Cannot create indexes on the flow table

  Hello

  I'm new to ODI.

  The problem is that during the execution of an interface, I get the error of the "IKM Oracle Dimension to slow variation"

• Is it possible to see the animation of the flow of electrons?

  I am a beginner and e-learning on my own.  I have Multisim v13 and I was wondering if it is possible to display the flow of electrons led thanks to a circuit?

  Something like this-> http://www.falstad.com/circuit/

  Thank you!

  Multisim is not a way to animate or electron current flow in the circuit. You can use sensors in different sections of your system to see the current within a particular section while the circuit is running, but there is no real way to see this animation.

• Help explain the flow meter VI

  After a lot of tinkering, I seem to have developed an effective VI for use with a type/pelton turbine flowmeter. The flow meter outputs a stream of pulses which

  can count on the counter of my 6501 line. Unfortunately this eureka moment happened somewhat by chance, and I'm hoping someone

  could be kind enough to explain step by step or in terms very simple for beginners (me) works of VI, thank you.

  Kind regards

  GER

  GER,

  Welcome to the Forums and LabVIEW.

  If you don't the have already made, please work through the tutorials online to get started with LabVIEW. The answers to some of the questions you may have are probably there.

  A brief description of your VI:

  1. the overall structure is a loop For. It works for the number of iterations that is connected to the Terminal in your case 5 N.

  2. the calendar of the loop is determined by the longest time required for any part of the code inside the loop execution. On the first iteration, the DAQ Assistant configures the counter and starts measurement. On all subsequent iterations, he reads everything simply an indictment. On these iterations, the 25 les 25 ms ms expect will dominate. This VI runs approximately 40 iterations per second (for 5 iterations).

  This means that the program will take place on 5 * 25 ms = 0.125 sec and then stops. If you run for more 1/8 of a second to help run it continuously button, STOP. Which is intended for certain types of troubleshooting only.

  3. the table of waveform and the flow rate meter only shows the last value of the five iterations. (This suggests also that you use run continuously)

  4. the registers at offset in this VI nothing do. The upper shift register calculates the cumulative number of the flow meter, but the result is never used. The underpass registry has nothing connected to the Terminal inside the loop on the left. It could be replaced by a terminal.

  Suggestions:

  1. in order to avoid using run continuously, replace the loop with a while for loop. Add a stop button on the front panel and connect it to the stop it real terminal in the loop. Move the graphic terminals of waveform and flow inside the loop.

  2 check your pulse to the algorithm of flow rate. The time for the count interval must be considered.  For example if the meter registers 25 pulse in 25 Member States, which represents 1 000 pulses per second. This isn't which will show your VI.

  3. see examples of code that uses counters.

• How to trace the signal acquired against the clock all the time fixed by using Graph XY?

  Hello

  My goal is to trace the signal acquired against the clock all the fixed time dynamically. In General, it is like trace the waveform of the signal against the clock in a graph, but don't keep the recent 10 min waveform. My current approach is to get the timestamp by a VI and the express VI to use XY graph to make the plot. The result keep all data in the history which is not what I want. My question is that how to achieve my goal?

  Thank you very much

  Hao

  One way to show the last ten minutes of data is to use a graphic instead of a graph. Set the size of the history of the ranking for the number of samples you acquire in ten minutes.

  If you want to use the graph XY, you will need to manipulate the data yourself. If you don't want data from the last ten minutes and you want to throw all the old data, set up a circular buffer sized to hold the ten minutes of data. Once the buffer is full (after the initial ten minute break) adding a data point removes the oldest point. Make the buffer of a 2D with X data table in a line and the data Y in the next line. A queue with loss can be used in recent versions of LV to implement a circular buffer. In older versions, a driving force would be a good choice.

• Controlling the flow of data

  Hello

  I'm working on a program in which I have to control the flow of data on the wires.

  The task is that the data should not pass until a given value is generated. And the program remains the playback thread until this value is generated.

  While the value received, now the passage of data to all loop regardless the data that is generated on.

  That's why I created two loops while we research this value and the other is the principal who must perform processing when the specified value is generated (taken in the first loop).

  It could also say that "wait until the reception of a certain value.

  

  The first loop is created just to wait until a value of 3.

  The second loop is the principal who must deal with.

  
  

• force the flow of execution

  I'm a newbie has arrived from VEE, so please be patient.

  Vee, I always sequence input pins and output sequence on any bow that allow me to force the execution of a box.

  In labview instead I'm not, so I guess that the execution order is always driven by data, correct them?

  Now, I just created a few local variables where I want to store internal information, so I have the objects in the front panel, and the 'local' connect to them in the chart:

  

  (as you can imagine, I'm changing a complex program, I didn't write it...)

  Now, since these couples: 'Acq length', 'timeIntensity', 'Acq Start time', in whole isn't all input/output, I don't see how to impose their execution. In fact, they are never executed...

  what I am doing wrong? Thank you for your help...

  Thanks for the suggestion...

  I am already tracking at least 3 manuals/tutorials in parallel,

  but nowhere I found an answer to this question.

  From what I've seen (Please correct if I am wrong), the execution goes according to:

  (1) the data flow

  (2) the error in / error on pins

  ... Since my case is not available, I'm really at a loss to know what to do.

  P.S. just in case my using local variables deemed not necessary: I transfer data using son whenever that is possible, but in this case I use inhabitants because I set a few values within a species a case structure, and I do use them in another case.

  If the transfer of data by wires between the cases is possible, I will be happy to hear!

  Alessandro

  You are on the right track, except that the error in and out is just another example of data flow.

  LabVIEW data flow can be summarized in two sentences:

  A node will not run as long as all entries are filled.

  A node will not produce output until the node has executed completely.

  When you boil everything down to basics, those are the only things that determine the flow of data.  If you take these two instructions literally, all cases where it seems that the execution order is ambiguous are really ambiguous - and you'd better fix it if a node is run before the other.

  It's really a case of 'easier said than done. "

• How can I analyze the flow on SF302 - 08 p

  Hello

  I have a SF302 switch - 08 p and I'm looking for an option to analyze all streams on it. I tried to enable netflow, but it seems that the product does not support because I can't access the stream ip like here: http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/netflow/configuration/12-4t/nf-12-4t-book/cfg-nflow-data-expt.html

  Thank you for your answer

  Hi Emmanuel, this product does not support anything like Netflow. Your next bet is SNMP and who would probably not do what you want, if you are specifically looking for the Netflow feature sets.

  One thing I have a question, when you say "analyze the flow of all", does that mean that you want to capture all the traffic, you can record and read it again? The closest you can do with is doing a session on the monitor for a VLAN integer and launch wireshark there to capture the data. I'm not sure that's what you want, but if you want to capture all packets and save it somewhere, it's a way to do it, but a bad way to do it.

• Understand the flow of appeal through VCS c/e

  Hey Geeks,

  I write this to understand "how to work things. Here's the design.

  I have a VCSC configured with the name of the domain example.com SIP (we have internal DNS server to resolve)

  I have a VCSe configured with the name of the cisco.com SIP domain (we have external DNS server to make globally routable)

  I create a link bw VCSC and VCSe course.

  How the call will flow between the Ep A and B Ep

  Scenario a.

  My Ep A is [email protected] / * / dials Ep B Jabber client (user) recorded on VCSe [email protected] / * /

  How call flows; I understand that the flow of the beginning IE Ex 90 will send a register message to VCSC etc etc.

  Scenario B:

  If Ep A [email protected] / * / call a 3rd party (distinct) = (inter appeal cases) End point ie [email protected] / * /

  How runs the call.

  Please excuse me for asking layman explanation:

  Thanks in advance

  Vikram

  Hi Vikram,

  First thing to note is in most of the customer scenario prefer same sip domain on highways and control so that they can avoid transform and simplify the numbering plan.

  Happens to your scenario.

  Scenario a.

  EP A VCS-contrl<--traversal-->VCS - Ex <--SIP--><--sip-->Ep B (points of termination assumptions made using the SIP protocol)

  EP began with the sending of a guest for VCS-cntrol SIP message, which gets transmitted to VCS - by VCS-cntrl exp, hope you're installation rules research properly on vcs control.

  VCS - exp send this appeal to Ep B and call connect. You can google for SIP call flow, so nothing different happens in this case.

  Scenario B

  EP A VCS-cntrl<--traversal-->VCS - Exp<-->public cloud<--SIP--><-->Ep B (dell.com)

  A DNS zone, which uses the dns configured on exp do query srv records to the external field like "dell.com" is now required to apply for external part VCS - exp

  in this scenario again Ep began with the sending of a message to the VCS-cntrl invitation gets sent to the SCV - exp rules-based research. VCS - exp begins looking for new address based on the rule of the research and since it does not find the URI ending with exp and "dell.com" starts to send query record srv for the domain "dell.com". DNS configured on exp in the SRV company A sends question and get an answer for this domain with the company B VCS - exp - ip address, and then vcs - exp in company A starting configuration of the call to the remote ip address.

  now in the present, you can have several scenarios and I recommend you consult the guide deployment for VCS-control and traversal solution VCS - exp.
