• Access a dll with a table as argument in Teststand

  Hello

  I did a dll with the following function call:

  __stdcall __declspec (dllexport) int FSCOM_ModbusQuery (int nComport, ucAddress unsigned char, unsigned char ucFunctionCode, unsigned char ucTxData [], int nTxDataLength, unsigned char ucRxData [], int nRxDataLength)

  I want to access this function call in Teststand 2010 SP1. I did table 2 in Teststand and gave addresses to the function call (as you can see in 'Capture.png' and 'Capture1.png').

  When I try to run the sequence I get an error on the ucTxData and the ucRxData with the message "number expected, found the table of numbers.

  How can I solve this problem

  Thanks in advance

  Wissam

  I think you have misunderstood what I wanted. In the specification of the Panel Module tab, you can change the type of data that the function expects. You probably set on the wrong thing. It must be set to an array of numbers where the elements are unsigned 8-bit integers.

• Use the type of data "table of container" in teststand

  Hello

  I have a problem with data type "table of container" in the TestStand.

  I defined an empty local variable in the form "table of the container" with the name "array_of_container1" and also a local variable as 'container' with a name "container1".

  The problem is, I can't insert the container1 in the array_of_container1 table.

  In the end, I want to get a picture of x items containers

  array_of_container1 [0] .container1,.

  array_of_container1 .container1 [1],

  ....

  array_of_container1 [x] .container1

  Thank you very much!

• How to store the results in several digital Test

  My VI returns two double individual (not in a table), output power and frequency

  I am configuring a multiple digital test in TestStand but struggling to store readings.

  Using the following, I get an error.

  Output power of VI: Step.Result.Measurement ["Measurement 0"]. Data

  VI output frequency: Step.Result.Measurement ["Measurement 1"]. Data

  Would appreciate some advice.

  Thank you

  Got, it works

  Results were to be stored in Step.NumericArray [0], Step.NumericArray [1] and not Step.Result.Measurement ["Measurement 0"] as I've had.

  Thank you

• Table of indicators clusters

  Hello world

  In my program, I have an array of clusters with controls and an array of clusters with indicators.  I created nodes of property for each table that updates the number of columns.  Each column represents a channel that is monitored on a DMM scanning.    My program works as I want to, with the exception of the battery of indicators.

  I have a VI sub which checks the value measured by the DMM and determines if the device measured by the channel complied or not.  In a cluster of indicators, I have three indicators: one for the measured current, one for the time elapsed and a boolean that indicates if the device has reached a limit.  The problem is that on the screen, I don't see the values entered in any of these indicators?  I'm newish to the use of tables of clusters and which do not.  Can someone please help me to see what I'm missing?

  I have attached my Subvi (LabVIEW 2015).  I know that nothing is connected to the elapsed time indicator.  I'll go to that in a bit.

  Thank you.

  What indicators are not see all values on? The Output channel indicator shows correctly it seems. Output display will always be no element in the table because you start at zero and then use the Replace table VI subset to add items. This will not work because if your table has a size zero, there is no element to replace. You can use an array to initialize (initially to match the size of the array strings) or use a different method of the edition of the scoreboard.

  Edit: I just noticed you do not use a very useful tool with loops: automatic indexation. This is something short of those. You can get rid of your shift registers and table manipulate nodes.

• empty fields of digital painting

  Hello

  I am creating a table digital indicator that contains blank fields for all the odd index. For example, (i = 1, 3, 5, etc...) Currently, I have a case structure to determine if the index is odd or even. For a same index, I pass the appropriate values in the function "insert table". For the odd index, I'm not sure what to plug into the 'new items/sub-table"Connector component to generate a value not intialized. Right now I'm wiring the constant infinite to use as an example. Ideally, I want the empty field. Thanks for the help!

  A digital cannot be empty.

  If it's just an indicator, you would simply substitute one string instead. It is possible to look the same. Here's a code option.

  

  Of course, if half of the elements are still the same (empty), it does provide all useful information to the operator. You can view both the items even without gaps. This saves you space in the public Service.

• Rotating table with 6 test stations. How to track the results data at each station to a machine of rotating table with 6 test stations?

  I would like to know if someone has worked with table Rotary testsystems and want to share an idea of how he dealt with follow-up of the results of each test result data in all the test station is in the table of rotation, so at the end of the cycle the results of good data by each DUT. There's a kind of technique used in arrays or clusters?

  Any comments would be grateful.

  Hi shada

  There are many ways that you can store your results, such as Matthew commented that you can use an array of Clusters. I would recommend this table of cluster storage in a Global Variable that is functional to make data transfer safer and easier to climb. There are many examples on how to use them on the community.

  There are a few tools in advance that you can also use to store your results as Of present value Tables (CVT).

  TestStand parallel model with the "Result of processing" option enabled stores automatically all the results of your Tests.

  Hope this information is useful.

• Sort of a group of numbers

  Hi all

  I am reorganizing my digital signals by the presence of a front panel control that allows the user dynamically set the channel.

  On the front panel, I have composed a set of unsigned integer typedef.  I want to sort this cluster in numbers and be able to exploit the case of the label.

  I understand how to assemble digital waveforms with digital subset and add digital signals, but I do not know how to sort the data structure I created.

  I do not know there is an easy way to do this and she escapes just me.  I'm on the right track with my data structure?

  You can use a Cluster for the Array function to get an array of the values cluster.

  You can create a table 1 d of channels where you hardcode the labels.  (There should be ways to get programmatically the labels in a script, but I don't think it's worth the effort).

  If you bundle up your array of numbers with your array of strings so that you have an array of clusters (each element of the array is a grouping of the value and the string), you can then sort the table 1 d.

  Even simpler.  It is not necessary to get the names of the elements of script.  I've added an example VI.

• String to number or array of spell

  I have 2 generators of different traffic from the entrance of the source address and destination.

  I need to read a .txt file that you want addresses and then set up the generators. I want the addresses entered in the .txt file will be in the same format that you can display in the interface generator (this is what I can't change)

  The problem is that each of them is using tables formats as input to the function, and I will read the string .txt file.

  For the first time in this moment I do like this:

  

  and as I lead and he's right, I have the 0-0-0-0-0-3 table:

  

  For the second, when I type directly in the generator of the 00-00-00-00-00-22 address, I will do a 0-0-0-0-0-34 table, that I am converting on Labview as below:

  

  as a result:

  

  So, how can I convert a , which will be written in the .txt file, in the table above?

  Thank you and I hope to be able to understand what I need

  OK, so to see if I understand you correctly.

  What you want to do is take the MAC address strings 12-digit (that you've already drawn your .txt file) and convert them into tables digital 6-members?

  If so, this will make that (once for each MAC address):

  

  Now, there may be (probably is) otherwise and this may not (probably is not) the most effective way to do it, but it will work.

• Increase the speed of this VI?

  It is a simple question - is anyway to increase the speed of the VI below?  Parallelize the outer loop, I'm given the sequential nature of the loop inside, I don't know if there is anything else I can do.  The problem is that I'm trying to eat a large amount of data - every second I'm producing about 1.25 MECH. / s and any attempt of this accumulate more than 10 s (Data In) to perform the calculations below on several periods of integration (iTime; currently 0.001 0.01, 0.1, 1 and 3 s) - and it is causing an overflow on some other loops.  Any help is appreciated.

  Hmmm... isn't using table subset incur a calculation that does not remove the table?  I'll have at least one node of multiplication (I * chunk size) to add to the inner loop that was not there before to keep the appropriate place.  On the other hand, which gets rid of the shift register.  Is there a significant difference in performance between the subset of table and delete...?

  Looks like you're right about single-precision calculation - can be significantly faster.  I will consider this.

  Thanks, Darin.

  You must test in LV12, in previous versions, remove that table is a dog, even when the end of the table is deleted.  I did a simple test, create a table of random numbers 50000 and take the average of the consecutive blocks of 400 items by using the two methods.  I even added a reverse table of subset test to match the behavior of deleting the table.

  Results:

  Delete: 2.7 msec

  Subset: usec 200

• access to an id in a subselect

  Hello

  I have the select...

  Select x.obj_id

  ,(Select b.class_id)

  from (select a.*

  ROWNUM rnum

  of (c.obj_class_id select class_id)

  of obj_class2 c

  ) x

  As you can see, I get an ID called x.obj_id which I want to use in a subselect. The subselect statement returns multiple values, and I want to extract the value 2. But if I try to say c.obj_id = x.obj_id, said oracle x.obj_id is an invalid identifier.

  If have tried a lot of things, but in the end I still get the same error. Any suggestions are welcome... of explanations too.

  Thanks in advance for your efforts.

  Hi chris227 and Chris Hunt

  Thank you very much for your explanations and suggestions, see the following select statement for a good solution.

  As I saw on your answer of my explanations when a little lacking. So, my main selection is, think I catch an obj_id and a large number of attributes of the obj. table a subset other attributes are on other tables that I'll go with the Subselects. It's why I can't do your solutions with the join. But, as you can see it works with the row_number() (c.obj_id of partition by c.obj_class_id order).

  I can name this statement of subselect with t and set the condition t.obj_id = x.obj_id which is located on the first level, so I can pick 1, 2. or 3. value, all that I need.

  Thanks again for your efforts!

  Best regards, Konrad

  ===================================

  Select x.obj_id

  x.whatever

  .

  .

  -Subselect for exactly numbered attribute fetch another table, which returns many rows (attributes!). The id on that other table is identical to the id of the main table.

  ,(Select t.class_id)

  of (c.obj_class_id select class_id)

  c.obj_id

  row_number() over (partition by order of c.obj_class_id c.obj_id) rn

• Database of learning TT

  Hi all

  I'm new to this ten times in memory database.

  I'm analyzing the scope of use for our web application.

  I went through demonstrations at the search of OLL , but always I have a few questions in my mind.

  1. my Oracle database implemented VPD (virtual private database). Only the TT a SPV?

  2. my Oracle database size is almost 5 GB which I want to keep in Cache database ten times. I understand that using Cache Group, I can be cached set of tables in the Oracle database in the database of TT. These tables must have a foreign key relationship. I have some tables in the Oracle, who are rarely updated database (say, my_customer_names, my_product_list etc.) even if there is no relation ship master detail, I CAN HIDE THESE TABLES in the database of TT?

  3. I do not understand that we provide a refresh interval during the creation of this group of Cache. How can I recover my data in the database of TT if TT database blocks in 2-3 seconds after you refresh. ?

  4. should I manually copy each stored procedure written in pl/sql in my Oracle database to the database of the TT? or there is a utility?

  5 are supported in TT database triggers?

  6. If there is a database of TT performance problem, how can I identify the neck of the bottle and the same tune?

  Bottom line, it is that I have an Oracle database for an application, I size almost 5 GB. I want to migrate because it is the database of TT (because I heard it's much faster) to make my web applications has everything in the cache, but finally it is written data in my original Oracle database. What is the best way to achieve this.

  Please tell me some docs for complete beginners.

  Thank you very much

  1. what should be the criteria for objects Oracle be cached in TimesTen?

  CJ > usually one puts cached tables, or subsets of the table, you have determined are a bottleneck access data for your application and that you have evaluated the benefit of their caching in TimesTen. As part of this evaluation you must take into account the differences between TimesTen and Oracle database and the impklications from a unique architecture of two database database architecture (stat in two different databases maintained in sync).

  2. I don't understand TimesTen is a different database altogether. What is the advantage of having Timesten between Oracle database and Application?

  CJ > for applications suitable, where TimesTen has been properly integrated into the architecture, performance improvements can be made. In addition, overall availability of applications can be improved as well.

  3. can we get rid of the Oracle himself and keep everything in TimesTen only (for faster response times). If so, why not all Oracle users migrate to TimesTen?

  CJ > in some cases, this may be possible, but it usually isn't. TimesTen is an another Oracle database, and while presenting many similarities there are also many differences. Oracle database has many features and features that are not supported by TimesTen. TimesTen is capable of supporting very large databases in memory (multi-TB), but these require huge amounts of RAM and can be difficult to manage (long start and stop times). TimesTen is best suited for specific applications that require the very short response time provided by TimesTen and which have been specifically developed, or modified to work well with TimesTen.

  4. I was under the impression that in TimesTen, entire database is in there before RAM, it is faster compared to the Oracle database. As you mentioned in your previous answer " simply migrate the entire database to TimesTen is unlikely to be a viable business or managed.", I think it's the entire database cache imprudent in TimesTen. We can be cached objects in Oracle as well using KEEP_BUFFER. What is the advantage to introduce TimesTen between Oracle database and the Web server for caching of ten COURSE Oracle KEEP_BUFFER times tables?

  CJ > these are totally different things. The pool KEEP_BUFFER in Oracle is just another area of cache in the CMS where you can place objects that are frequently referenced. But there is still no guarantee that these objects are always kept in memory; the contents of the pool can be aged just like for any other cache pool. Even when the objects are in memory, it is still very different from TiemsTen because:

  1 TimesTen stores and manages all the data using the formats of memory optimized storage, techniques and algorithms of indexing access. As a result, using much less CPU cycles to perform SQL operations compared to access in memory of the floppy based in a database of disc based data. It's the principle of the actual performance of all of the databases in memory; not so much exploitation of data in memory, but the use of storage memory optimized formats/structures and algorithms of access.

  2 TimesTen is usually deployed on the same computer as the application. Therefore, the application can use TimesTen link 'direct' extremely fast and highly optimized mechanism in order to avoid any inter-process (or network) communication between the application and TimesTen. Largely, this increases the efficiency of the interaction of the application/database and translates into improvements in important performance, especially for OLTP-type workloads.

• TestStand table average

  Hello community,

  Using 32-bit Teststand 2014

  I have a one-dimensional array with a size ten (Array [10]). I want to be able to take an average of this table in Teststand. Using an expression of the statement, I am able to do digital = ((Array [0] + tableau [1] +...)) Array [10]) / 10), but this is tedious. Especially, if I have a table for more than a decade.

  In Teststand, is there a mathematical operation or another way to get the middle range?

  I don't think it's possible in a single expression.  Consider the attached example that does it in a single step.

  Hope this helps,

• generate the subset of the decimal table to an array of Boolean

  I have a decimal table 1 2 3 4 5 6, and I have a boolean with the same table size 0 1 0 1 1 0.

  How can I retrieve the subset of the decimal table of the corresponding "1" position of the table of Boolean (in this case 5 4 2)?

  The value of the Boolean table are editable (casting either 1 00100), so the size of the array decimal subset is not fixed (1, 4).

  (I assume you mean digital Board. "Décimal" is just a specification of formatting and irrelevant for this)

  Try something like the following (the FALSE case has just wired table in the whole unchanged):
