Linking a Varable shared several MODBUS registers

• writing multiple modbus registers

  Hello

  I am communicating to my labview program controller using modbus RTU and the controller has 16 bits in modbus registers.

  To send the float as '1.23' values, I write two registers to store the hex value that number in comma floating 32 bits.

  I use the modbus driver provided to this end by labview and use labview 8.2.1

  I have the following doubts in this regard.

  1. The "Modbus master series query. VI"has the command Modbus that records an entry which I use to set the registry values in the controller unit modbus. To send the above, mentioned in floating-point registers 501 and 502 (contains the full value of the PID parameters), use the same vi, whose value should be registered first... is the high or low, to be written to 501 and 502.
  2. The function code to write to multiple records in the modbus driver is 16. But my document that is specific to the Controller explained in the section "writing to multiple records" with the code of function like 10. And I see that feature codes 'writing in the single register' as well as the driver for modbus producing the same type of message frame as discussed in the document. But I see no similarity in the function "write multiple registers" in the document and the modbus labview driver.
  3. "Even if I write records 501 and 502 one after another will use"write in the single register"function code when these registries implement floating-point single using 2 registers ' 16 - bit '. If this method is possible, then I will come and do it the same way I did it for the entry in the single register. While writing data in records one after the other with a gap between the two as small as 4 ms scriptures do good?

  I suspect a confusion between 16 decimal and hexadecimal 10

  Two successive registry entries are not equivalent to a double entry: during the period between the two scripts your controller will be loaded with a false parameter. It is perhaps not necessarily a source of problems. It depends on your application. Writing the MSB should first reduce the problem.

  The order of Hi-Lo is dependent on the machine control. Some use the Big Endian, other Little Endian. But this choice should assign unique register values (U16) as well.

  If it is not documented, you should read the records and see if the result is logical. If this is not the case, invert the byte order and verify that the problem is resolved. Good luck

  Also, I assume that you know how to use the conversion feature to convert a single (32-bit float) 2 U16?

• Using NI MODBUS - reading of several distinct registers

  I'm using LabVIEW 8.6, with the NI MODBUS 1.2 VI library. I have a device which serves up to 50 records, all keeping the same format. I want to read about 20 of them, however they are not consecutive.  (40010, 40015, 40017, etc.)  Read Holding Registers VI gives me the opportunity to read consecutive registers beginning at a given address.   On the other hand, writing several registers VI seems to me to write in an array of distinct registers. Is it possible to do it for the reading of records?

• Several Modbus with shared serial port

  I know that Lookout lets do you cool things like have several protocols series that share the same serial port hardware.

  I asked where I might like Lookout to simulate a network of Modbus Devices for some tests. In this case, I want to implement multiple Modbus slave, all with different node addresses Modbus objects and have all listen to the same serial port. Would this be possible? Each received Modbus message will include the number of slaves in there. Multiple objects can listen on port and only the selected one respond?

  Thank you

  Max

  Yes, slave modbus Lookout can work this way.

  But the ethernet mode does not support.

• Read MODBUS registers

  Hi all

  I have been more manuals/son using the Modbus Library to communicate through series. However, I'm not sure what exactly I am doing wrong. If I use a program like Modbus Poll and send 02 03 00 02 00 02 65 F8 I get a response: 02 03 04 39 20 90 D5 F9 3F. Looking at the manual for the device that I'm communicating with (a pressure transmitter), the application is in the following format:

  02 - address

  03 - function

  00 - StAdd H

  02 StAdd L

  00 - reg #:

  02 # reg L

  65 CRC16 L

  F8 - H CRC16

  The answer is in this format:

  02 - address

  03 - function

  04. # of bytes

  39 data:

  20 - data L

  3F - data:

  90 data L

  D5 - L CRC16

  F9 - H CRC16

  So, in LabVIEW, this is how I have it Setup:

  

  I put the 'Start' address to 1 because I have read, there must be in LabVIEW 1 less than what the actual starting address is (n - 1). I expect the same reply as above using Modbus Poll. In the diagram above, I get the following registers, starting at index 0: 256, 661, 63490 33538

  Obviously the answer is not in hexadecimal as above, but it is nowhere near what it should be.

  Thanks for the help!

  
  

• The SharedObjects sharing several .swfs

  Relatively simple problem; I have a project that I think may be easier to manage if I break upward into several .swf files small rather than having a gargantuan mega .swf.

  Now, I know I could use a .swf root and load the data of others, but I think it will be much easier to debug and to update if I use separate autonomous .swfs, so this is the direction I look at currently.

  However, the .swfs really won't work unless I have persistent user data between them, so I wonder if I can load a SharedObject saved by another .swf file? Are there any major caveats that I need to know?

  In particular, can someone give me example of code that would allow me to do this with a copy of the files. both online and offline IE - if I run the same set of haravikk.com .swfs, and locally, I want to still be able to share data with one another. In this case although I won't need to worry about the sharing of data between a local copy and haravikk.com, as long the files themselves can pass data in whatever the field, be they charged it should be good.

  No magic! Just read the data in another swf file. give it a try. But he will recover it where you've stored, means, another swf file will retrieve the content of the PC even not on another pc.

• creating a linked css that affects several Div in the HTML

  I create a css file to attach several html documents.

  within these HTML is a set of regions Ap Div with the text of the hyperlink in them.

  in the css style box, they are named

  #apBttnAbout

  #apBttnAbout:hover

  #apBttnContact

  #apBttnContact:hover

  I took the apBttnContact: hover # (has a colored background) and turned it into: hover so that it would affect all the #apBttn.

  but he ended up making all my Ap Div regions including my #mainLayout

  Basically, how to create a style #apBttn:hover can I use it for everything with the beginiing #apBttn title?

  In this example, you will find that links are exacerbated specific divs that are nested inside other DIV tags This allows you to have a particular style applied to a specific area without applying it to the entire site. Obviously, you'll need to set up a div for outerWrapper, one for contentWrapper and leftColumn1 to work. So what happens, it's whenever you create a href in the leftColumn1 div, the style is automatically added. If you did not compose as I showed, and then links the entire site would be affected by this css. The following creates a red box with white text, which when twitch, it turns into a grey area. Basically you take control of the

  #outerWrapper #contentWrapper #leftColumn1 a {}

  background-color: #c6402f;
  padding: 3px;
  Width: 50px;
  color: #FFF;
  make-weight: bold;
  text-decoration: none;

  }

  #outerWrapper #contentWrapper #leftColumn1 a: hover {}

  background-color: #666;
  }
  These are the classes that you apply manually (note the point before link3px) but once applied they are controlled by these few lines of css code.
  .link3px a {}

  background-color: #c6402f;

  padding: 3px;

  Width: 50px;

  color: #FFF;

  make-weight: bold;

  }

  .link3px a: hover {}

  background-color: #666;

  }
  Simple!

• Reissue of links binary Oracle and several houses of Oracle

  Hello
  
  My question is related to the reissue of Oracle binary links in the following scenario:
  
  In the largest migration project, we are moving all the databases from one server to another. Old and new server operating system is the same: HP - UX 11.23i. There are 5 databases on the source, each with its own Oracle Home (and binary Oracle) server. All binaries for all Oracle databases are version 10.2.0.3.
  On the new server we have some of the migrated databases already in production. Now our DBA wants to move another data base, and given that for each binary database are also moved from source to the destination server, it must create a link to the binary files on the target server. We must stop all databases on the server target to re-edit it for that one DB, even if they all have different Oracle Homes (binary)?
  
  Thanks for your replies
  Maciej

  If each database has a dedicated ORACLE_HOME, just stop the database in the ORACLE_HOME you are re-binder. Other databases on the server that have their own dedicated ORACLE_HOMEs can be left running.

• A link to a shared image... help

  I'm trying to set up a page that contains a right column of thumbnails, which, when the clickedon opens an expansion in another region. I did it using swap image. It is all set up, but now I would like to than the bigger picture and a link to another page... one with zoomify to view large details. I can't find anything in DW cs4 to make... the only way that image exchanged appears is in mode Live View and live according to the image is not selectable.

  Thanks for any help.

  It works very well.  Click on the thumb and the bigger picture and is available in.  Click on the enlarged image and you go to my site.  Was not what you wanted?

• writing in shared variable published network hosted on rt (defined as slave modbus for crio) problems

  Hello Forums or

  This is my first post on this forum and I've been using labview for about 8 months now

  I have a problem about writing data in the modbus registers through a server of e/s defined as a slave modbus for my hardware 9074. Once I finished the project of construction and deployment of the variables and by following the instructions here , he reports no results but a row of zeros. I have the DSM nor opened and configuration modbus master to see whether the data is actually read or written on the respective sides that give the same line of zeros so.  What I am actually trying to write is a single-precision floating data table. The registers are structured F40000-F46534 runs from 10 items or have them for range AF40001L1-AF46534L1 of the AF40001L10 point where it's an array of length 10. (Referenced beaches here)

  I know 1 thing for you, the modbus connection works and is ready for data requests, I tested cela NI DSM and set manually the data for and received my master.

  Image of data written in scheme-block rt variable

  Short version of the problem: why is the e/s no variable writes in with the converted correctly data?

  Okay, Yes, it's that I was the one proposed. Regarding the news of the error, if you look at the bottom of your image to DSM, you see a little commfail and an error code, but it seems that those are OK.

  The only thing I can think is that DSM (or another function) is written for a range of values that includes 400004. I suggest you to put into service 4-going to a range of 3. 3 s are entered only (perspective control), then you can be sure that the master is not trampling on the data. Once you have checked that, look at DSM and any other code running to make sure q EU not accidentally write 0s to the same reg.

• Need help with shared links

  I need help understanding the shared hyperlink option when creating hyperlinks in InDesign CS5 (Mac) and how to change a hyperlink target shared.

  I want to build a document that contains links to files on the server from the client. The final use is to make a PDF file in which the customer can click on a hyperlink and the opening (for example) a Word document or another PDF file on their server. When I started the project, I thought I would create shared links because a single server document will be returned by several links dispersed throughout the InDesign document, that I was building.

  In the hyperlink palette dropdown I chose the new hyperlink, then Link To: file in the drop-down list, and I clicked on the hyperlink and then sharing option on OK to close the window. I export the InDesign file to PDF print, and hyperlinks work.

  Now, I need to change the paths, because the customer moved their files to a new location. When I re - open the hyperlink in the hyperlink palette by clicking twice on it, change the hyperlink window opens but it shows my link as:

  Link to: Destination shared (rather than File)

  And the area of destination below shows:

  Document: [my name of the document]

  Name [the path of the file I put in]

  However, this link is not editable. I do not understand why InDesign is doing on its own.

  

  I realize now that it was not necessary to check the shared option when I built the hyperlink. Is there a way (a script? another method?) that I can remove the nature shared hyperlinks so that when I go to change them, they show that links to files (link to: file, no link to: shared Destination) with a live box Destination path where I can change the link?

  (If someone tries to help him with a script, note that my document also contains the other hyperlinks to websites and emails that I don't want to bother).

  Thank you for your consideration.

  Well. I feel kind of bait and switch, but...

  I want to get links to the point where double clicking on the name of the (number) hyperlink in the hyperlink palette opens a dialog box change the hyperlink where the destination's link to: file and the path to the file appears in the box path as an editable string. Just the way I had them in the first place.

  It is good that you are comfortable the IDML of edition.

  If you compare the links made in two ways in the IDML, the only distinction between the Shared and non-shared seems to be the hidden attribute of the tag.

  Would have been impossible to change this in Javascript (although you could, I suppose, create a new HyperlinkURLDestination with all the same properties and then chang each hyperlink points to it).

  But by changing in the IDML works very well. Open designmap.xml and replace the Hidden = "false" Hidden = "true". Of course, you want to only do that in the tags...

  Something about this seems fishy to me, then you want to check yourself in a single case before putting too much effort in. But I think it's good.

• several registers with shift in loop For

  I use several shift registers to find the number of different string to an array of strings. However, the shift register got updated whenever he finds another string and returns to 0. How can I have the registry remember its previous value, after that he meets a new string value?

  Tunnels unwired in the structure of your case are configured by default so Unwired.  The default value is zero.  The answer is to wire the tunnels.  An easy way to do this is to click on each of the tunnels out and under related entry Tunnel, choose Create and wire Unwired case.  You then click the corresponding entry tunnel.

• SQL or PL/SQL to display several links of BLOB in the column of the IR

  I have a need in an IR or a standard report to provide a link to view/download several BLOBs. Basically I have a function that, for a given record, will focus on a relational table and get a list of all the associated files and it has a list of output HTML. List the files is great, however, I would like to take a step further and actually have the names of files as a link to view/download the actual file. Reading the API on GET_BLOB_FILE_SRC it doesn't look like it can do what I want, because it requires a valid page for the file element, and I have 0 - x files associated with a row with a given number of lines per page.

  Basically, what I have is...

  Select

  some_pk

  some_data01

  some_data02

  custom_function_get_files (some_pk)

  my table

  order that either;

  It produces something similar to...

  PK	Data 1	Data 2	List of files
  1	Something	Something	File01.txt File02.txt File03.txt
  2	Data	data	Image.PNG
  3	xxx	xxx	(NULL)

  .. and so on.

  Of course, if I did only 1 file I can format the column of type BLOB and APEX type takes care of everything. Any ideas or suggestions?

  I know I could create a list of files as a link to another page, passing the key document and that the 'view' file using this page. Even if it's a little more messy.

  apex_util.get_blob_file_srcis indeed what you are looking for. The parameter item page is simply a shortcut used to get information about the BLOB of metadata associated with items to upload files and ARF process used to load the images. If these elements do not exist because the images are not loaded in this way, simply add the upload queue and ARF process that would be used to do this to a page, the conditions never set on them so that they are not displayed or executed and reference the element in the apex_util.get_blob_file_src call.

  The list of files can be generated in the query using SQL/XML to eliminate the need for a custom function:

  select
      t.some_pk
    , t.some_data01
    , t.some_data02
    , xmlserialize(
