Does Labview support comms with a q-series PLC

Hi
Does anybody know of a opc driver that allows comms to a Mitsubishi Q series PLC from Labview
Thanks
Paul

Paul,
There's nothing for the Mitsubishi Q series PLC's in the NI Lookout Protocol Drivers.
There may be something from the manufacturer of the PLC, or a 3rd party, which can talk to the PLC and also communicate OPC, which LabVIEW could then read. That's a common solution.

How does Labview support redundancy?

I have a control system and Labview will act as the means of control/monitoring. However, I want to have a primary and secondary computer with duplicate system setups. How does Labview support this type of redundancy such that if the primary goes down, the secondary will take control seamlessly.

Hi,
LabVIEW has many capabilities that can be combined to create a very robust redundant system. Some of these features include the following:
Archiving databases periodically
Monitoring a process on a remote machine
Executing an application on the backup when the primary has failed
The most straight forward method of implementing the monitoing is to use discrete memory tags to create a heartbeat. When the heartbeat on the Primary machine has stopped, the backup should take over and begin execution.
If you have specific questions about how to implement this, feel free to call support by going to www.ni.com/ask.

Mike

Does LabVIEW support the SNMP (Simple Network Management Protocol)?

I looked at LabVIEW 2014 online help for some info on SNMP.
A problem was posted in 1996 and updated in 2008.
Does LabVIEW Support the SNMP (Simple Network Management Protocol)?
http://digital.ni.com/public.nsf/allkb/4CD3625A939A77DE852564050047D3BD
This was addressed to LabVIEW version 4.
What version are we up to now?
Version 14?
One solution offered was to get the SNMP VI from Viodia.
Why should I have to spend another $1,000 for a VI from Viodia after spending $5,000 for LabVIEW Professional?
Come on National Instruments, offer up SNMP to go with your professional package.
There seems to be a lot of chatter about SNMP on the forums.
I’m sure a lot of customers would be happy to have an official LabVIEW VI for SNMP.

I find it unreasonable to expect that LabVIEW supports out of the box every network protocol that has ever been invented under the sun. You may find SNMP to be the most important protocol on the world but for most programmers it is a niche protocol that they may have heard of but never will happen to come across in their applications. It's in fact pretty low level for a very specific purpose of managing network connected resources.
On the other hand it is not rocket science either so can be implemented by someone with enough determination on top of the native network interface functions in LabVIEW. Is it a lot of work? Yes, you bet! Is it worth 1000 bucks! If you really need it and your own work hours cost anything more than a few cents per hour, most probably too! If you can live with an implementation that is supporting many but not all features of SNMP, the link on LAVAG is a very good and nice one.

HELP!!! Does LabView support a thin client or dumb terminal (diskless workstation) type of deployment

Hello,
Does LabView support a thin client or dumb terminal (diskless workstation) type of deployment? I have a need to run LabView on some sort of dumb terminal / diskless workstation. If someone has deployed LabView in this matter, please provide me all the details on how this was accomplished (software, hardware, etc.)
Thanks

Sorry, can't call you.
My first suggestion has nothing to do with LV. It is simply connecting as a remote client to the windows server and controlling the windows session on the server.
My second suggestion involved writing a program which will contact the PLCs directly using Modbus and get the data from them. As mentioned, you can find some Modbus client implementations for LV by searching the web (or, if you have LV 8 and the DSC module, I think it should come built in).
My third was writing 2 programs - one would run on the server and one on the client\s. The server program would be responsible for sending the data to the client and the client would be responsible for interacting with the user and sending the appropriate messages to the server. I already gave you pointers on what to search for (the example finder can be found by going to Help>>Find Examples and the site can be searched from the box at the top of the page, but make sure you don't search just the forums).
In both cases, you would need to design the program and the interface for the user.
Wi-Fi also has nothing to do with LV and is simply a way to form a wireless network. Any mobile device would almost definitely have support for it and buying an access point to form the wireless network is easy and cheap.
To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. Here, here, here and here are a few you can start with and here are some tutorial videos. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).

Does LabVIEW support Mobile and Wireless Protocols?

Does LabVIEW support these protocols;
3G     GSM        PHS
4G     HCSD        TACS
CDMA     HSDPA        TDMA
CDMA2000     iDEN        TD-SCDMA
EV-DO     Mobitex        UMTS
FDMA     NMT        WCDMA
GAN     PCS        WiDEN
GPRS     PDC        WiMAX
If it does (some or all) of these protocols, what do I need to install to get VIs supporting these protocols (I mean which packag/ toolkit etc contians supporting VIs/ functions etc)?
Thanks for your help!
Have a very pleasant day!

Most of these protocals are OS-supported. LabVIEW doesn't have lower level interface VIs.
For instance LabVIEW doesn't build a TCP/IP stream with header and stuff, the OS TCP/IP stack deals with that stuff.
For testing the quality of such network there are special hardware (most PXI) and software solutions.
What is it that you want to achieve?

Does LabVIEW support Multi Document Format

Hi
I had a doubt that does LabVIEW support Multi Document Format like Microsoft Word, execel etc.
please reply me with some solution if anyone has
With Regards
Avni

Yes, I know very well what MDI is, I just don't know what Multi Document Format is
Programs like word, excel, etc support reading/writing of files in multiple formats (e.g. *.doc, *.rtf, *.txt, etc. for word or *.xls, *.csv, etc. for excel), so the question could be along these lines. I guess we have to wait for the original poster to come back to clarify.

Does HSSF support Excel with Picture?

The following code works fine if the Excel File "test.xls" does not contain picture.
It also runs without error after I have added a picture to the Excel sheet, but when I open the excel file "test.xls", I got an error message "Unable to read file".
Does HSSF support Excel with Picture?
POIFSFileSystem fs = new POIFSFileSystem(new FileInputStream("test.xls"));
HSSFWorkbook wb = new HSSFWorkbook(fs);
HSSFSheet sheet = wb.getSheetAt(0);
int r = 10;
short c = 10;
HSSFRow row = sheet.getRow(r);
if (row != null)
if (row.getCell(c) != null)
row.getCell(c).setCellValue("testing");
else
row.createCell(c).setCellValue("testing");
FileOutputStream fileOut = new FileOutputStream("test.xls");
wb.write(fileOut);
fileOut.close();

If it must be dynamically embeded, you're SOL AFAIK. You can embed images in a template, then open that template and add data. POI will allow images and pivot tables to be in the original document and it will save them undamaged, however you cannot create images or pivot tables from within POI (HSSF).

Does LabVIEW support USB 2 interface?

I need to transfer data from the USB port 2 but I'm thinking of using LabVIEW for interfacing. Does LabVIEW support USB2?

Yes, you can talk to USB devices using the LabVIEW 7e VISA VIs (see the attached image of the VISA USB Function Palette).

Metaprogramming - does LabVIEW support reflection?

Does LabVIEW support reflectivity in metaprogramming?
By this I mean, can LabVIEW programatically generate LabVIEW code? Can one write a VI whose output is other, new VIs?
I think this amounts to a question of whether there is a way to create data having the same type as VIs do, for example by writing binary files. I've looked at .vi files in a text editor, and there is not much I can make sense of.

Definitely not the first. NI created scripting so it could be used (for the vision builder, if memory serves) and use it they do. When you use LVOOP, for instance, you use scripting every time you create an accessor VI. I'm sure there are other places where it's used and it looks like NI is making it more organized. 8.6 has a folder of VIs which seem to translate XML into scripting commands. I haven't looked into this, but I assume this was done because it's used somewhere, not because NI felt like playing around.
What can I say?
Yep!

Does Labview Support a Hierarchical VHDL Instantiation into Labview Clip Nodes?

Hello,
Does Labview Support a Hierarchical VHDL Instantiation into Labview Clip Nodes?
I followed the available help, and called out the top-level VHDL in my XML file. Unfortunately, my lower level VHDL components are being read as a Black Box and I am getting an error during compile. So, what must I do to instantiate hierarchical VHDL code into a clip node?
Solved!
Go to Solution.

Yes, but you need to include the paths to all of your VHDL files in your CLIP XML. This tells LabVIEW which source files to copy into the compilation directory. Here is an example (which assumes the source files are in the same directory as the XML):
<CLIPDeclaration Name="NI Example CLIP">
<FormatVersion>1.0</FormatVersion>
<CLIPVersion>1.0.0</CLIPVersion>
<HDLName>ExampleClip</HDLName>
<ImplementationList>
    <Path>ExampleClip.vhd</Path>
    <Path>SubComponent.vhd</Path>
    <Path>Fifo32.ngc</Path>
    <Path>ExampleClip.ucf</Path>
</ImplementationList>

Does it supports writing with stylus .

I have a windows tab on which I have installed thunderbird, but it does not support writing with stylus. Pl advise. The MS outlook supports stylus.

yea same question here, I mean they are supposed to be supporting adobe line and sketch by the end of this year ish I think. But adobe draw is just a much better app imo.
If there will not be support soon I will have to buy the adonit Jot Touch instead of the Creative Stylus 2

Does labview support dll which has sub functions that are static functions?

Dear all,
I wrote and compiled a C function into dll to be called by labview. The function calls a sub function. It works fine if it is a normal sub function. However I see that if I declare the sub function to be static, labview will crash. So is it that labview does not support static function in dll?
Best,
Miao

A static function simply means that it is local to the C module that defines it and can't be seen from other C modules in a library. It should not change anything else about how it works.
So in conclusion it should not make a difference in if it crashes or not but only create possible problems in linking the library. It seems extremely likely that you have another problem in your library that gets somehow triggered more easily when you compile your code with the static functions, but it should not have to do anything directly with the fact that you have static functions in itself.

Does LabView support RS232 Z-Modem Protocols?

There is the possibility to send Files with z-modem transfer protocol via the hyper-terminal. Is it also possible to do the same thing with LabView?
Thanks for answers.

Hello Suttema
I think Labview does not support zmodem directly. You will have to use a dll or an Antivex.
The one from adontec (www.adontec.com) looks interesting. You can google for more.
Hope it helps

Does Oracle Support Searches with Sentence and Paragraph Proximity?

I have successfully used SENTENCE and PARAGRAPH special groups and the WITHIN operator to search for terms contained within the same sentence and/or paragraph. However, I also need to search for terms that are located within a variable number of sentences or paragraphs of each other. For example, I could search for the term 'dog' and the 'cat' located within 3 sentences of each other. Is this possible in Oracle Text? I have searched the documentation and I can only find the 'near' operator for searching based on word proximity. I cannot find any mention of sentence or paragraph proximity. This is a very important requirement for the system.

Good question. We are trying to duplicate the functionality of an existing system. It was written into the requirements for the new system. I've asked how important this functionality is to the actual users, but we don't have the answer to that question yet. Knowing that Oracle Text does not support this out of the box, we will certainly need to evaluate the importance of this feature and determine whether it warrants some custom development or switching to another search technology.
I've thought about using regular expressions to implement this feature, but I'm guessing that the performance wouldn't be that great and it wouldn't integrate well with other Oracle Text searches. Has anyone else used regular expressions combined with Oracle Text to implement more sophisticated searching capabilities?
