What application is limited in labview?

I want to know what is limited in labview..,and also I wish to know that which application v can perform using labview..
Thank u,

As Norbert indicated your question is rather vague. To date, I haven't really found anything I couldn't do in LabVIEW with the exception of selecting it as teh language to develop the embedded firmware for a product which is not using an NI board. I haven't followed this recently but perhaps NI is supporting the use of a generic board using an ARM processor. Other than that, just like any other language you can write code to do basically anything. The results and outcome are directly related to the experience of the developers and the quality of code. You can write really good applications in LabVIEW or fail miserablely. This is true for any language though.

What are the limitations of using labview 8.5.1 developers suite verses a real-time module in field point applications?

What are the limitations of using labview 8.5.1 developers suite verses a real-time module in field point applications? Can an exe. be loaded onto a field point controller or does the controlling program have to reside on a PC for example?

centerbolt is correct, you can't load a .exe or even run a program on the fieldPoint controller unless you have the Real Time module. However, that does not mean you can't use your FieldPoint bank without the Real Time module.
From LabVIEW for windows you can make calls to the fieldpoint IO using the fieldpoint read/write functions.
This program runs on the PC not the FieldPoint controller. If you loose network connection to the fieldpoint, your program will loose connection to the IO. For many data logging applications this type of arrangement can work just fine. However, if this is the only type of application you are ever going to run, then you may as well not buy the Real Time controller for your fieldpoint but the network controller only.
If your application requires more reliability, and/or greater determinism than can be achieved by running a program on windows, then you should use the LabVIEW Real Time module and develop a program that can run down on the FieldPoint controller independent of windows.

The limit to imagination for what we could achieve using Labview

Hiya
I would like to create a user interface by customizing front panel so it could be used as an oscilloscope. This oscilloscope allows user to do following selections.
Analogue or digital signal
which channel
raw binary data or scaled measurement
enter mathematical formula
and then it displays the signal. There are some knobs which could be used to zoom in or alter display to ficilate analysis. This is just imagination, Is it possible to achieve this on Labview. What are the steps please??
Your help is much appreciated.
Ta

You can download and install the NI-SCOPE driver, which includes the NI-SCOPE Soft Front Panel, an oscilloscope application written entirely in LabVIEW. This will give you an idea of what is possible (essentially anything even vaguely reasonable, plus a lot more, limited only by your imagination and skill). Unfortunately, the driver is very large. If you want a picture, check this out.
The underlying architecture of this application is virtually identical to the architecture given in this post. However, you would probably be better off following Ben's suggestion to hone your LabVIEW skills, then dive into the xylophone example.

I have trouble in building stand-alone application, "you must intall Labview run-time engine on any computer on which you want to run this application"

I have installed the LabVIEW 7.0 run time engine and checked all in the advanced setup on the installer setup slide. but I still get such a message saying that the target computer needs to have LabVIEW 7.0 run-time engine. What I want is a real stand-alone application even without having labview ... I used to think that's due to my program contains MATLAB nodes. But this is not true, since even without Matlab, it's still wrong. Please help, thanks!!!

As was stated elsewhere, you have the option of building the runtime engine into your application when you build it. However, you can also create a "runtime engine application" by simply opening the application builder and doing a build without adding any source code files. The result is a small program (named lvrt.exe) that can run any LabVIEW code--whether or not its built into an executable.
Such an application can be helpful if you are wanting to install several LV-based applications on the same computer in that it reduces the amount of redundant code on disk. All you have to do is make sure that Windows on the target computer associates the llb and vi file extensions with the runtime engine program.
It can also be helpful during testing to run test code that isn't built into an executable.

What is the limitations of an Openhub

Hi
When we use openhub what is the limitations.
Is there any limitations of an Openhib
shankar

Hi BI,
The Open Hub service enables you to distribute data from an SAP BW system into external data marts, analytical applications, and other applications. With this, you can ensure controlled distribution using several systems. The central object for the export of data is the InfoSpoke. Using this, you can define the object from which the data comes and into which target it is transferred.
No real technical limitation if you are looking for bulk transfers
You may have to manipulate a datamodel to suit the scenario as the OLAP processor is not used
SO if you have complex requirements you may have to create a query to APD into a DSO then open hib from there
And naturally if APD starts to have memory problems then you use the infoprovider read function module to do have an ABAP to read data then into a DSO and open hub out
I dont really use open hub off standard cubes as there is always a OLAP requirement in the extraction fo data
Naturally if you require just to dump raw data out then you could open hub of the cubes - but in that instance your global IT architects may ask why you are dumping data to a third party tool where they could come in on OLAP BAPIs etc at run time to access BW ie extra front ends
The functionality will work with extraction to a database table.
In BW 3.5:
The assignment of Open Hub Destination and InfoSpoke is an one to one relationship. One InfoSpoke
should not be used in more then one process chain. For the extraction, the database table must
contain the technical key. This option must be set.
An InfoSpoke should be a used at most in one process chain.
In NW2004s:
It is possible to assign one Open Hub Destionation to more then one DTP.
One DTP can be a process step of more then one process chain.
In the runtime only one request can be loaded into the Open Hub Destination. The next load can
started, if the status of this request is set to u2018Greenu2019.by the 3rd party application.

What are the limitations of remote API?

Excuse me,
I am new to Oracle BPEL, and going to customize the worklist application using remote API.
I read the Sample Worklist Application for learning the remote API.
When I learning about task attachment's API,
I saw a thread
RemoteWorklistServiceClient -- attachment
Suddenly, I found that there is different between local and remote API.
Would anyone like to tell me what are the limitations of remote API?
By the way, could there is any API for retrieve process list?
The reason is I am trying combine some feature of the console into my worklist application
such as list process with details, deploy/undeploy process, active/retired process lifecycle and turn on/off process state.
I only found how to start process:
Locator lLocator = new Locator({Domain}, {Domain.Password}, {Properties});
IDeliveryService lDeliveryService = (IDeliveryService) lLocator.lookupService(IDeliveryService.SERVICE_NAME);
lDeliveryService.request({ProcessName}, {OperationName}, {NormalizedMessage});
Thank you very much ^^
Roy

Excuse me,
I got the answer by testing the remote API
And I have another question about the BPEL API which used in the console
I have success construct the class com.oracle.bpel.client.Locator
It providing a set of methods for invoking Oracle BPEL
However, the methods always using WhereCondition as parameter
therefore, I need to know about the database.
1. Could anyone tell me where can I found the database schema?
2. There are some deprecated APIs what is the preferred APIs of them?
- IDeliveryService.SERVICE_NAME
- IDeliveryService.request({Process}, {Operation}, {NormalizedMessage})
- IDeliveryService.post({Process}, {Operation}, {NormalizedMessage})
Thank you very much ^^

They assume changing the file ending actually changes the format?

What application(s) would you suggest?

Hi!
I am totally new to dynamic web pages. I see that many applications exist but I am unable to find which one could help me achieve what I want for my web site.
Here is my situation. I have a list of local farmers and food producers and I want my web site visitors to be able to search that database with the options that suit them the most, regarding their needs. My list is in Excel and I am able to sort the data in many useful ways using Pivot tables. I would like to find a way to get the same kind of sorting in my web page.
My web site is promoting local farmers and food producers. I would like my visitors to be able to search my database in two ways. First, choose "including" criteria by clicking a check box (only organic products AND only products avalaible directly at the farm, for example). Then, sort the results by product category, or by producer, or by city...
Any idea how I could do that? What application I could use? If you give me a hint, I could then search the Web to learn how to do
Thanks!

You would be looking at using a database, something like mySQL and a server side scripting like PHP.
As far as I know, there really isn't anything out there that would allow you to do this type of thing in a dialogue window driven "click here for x setting" type of interface like DW's Design View. You're pretty much limited to hand coding.
Both of those technologies are very worthwhile to learn though and what you want to do isn't terribly complicated for them.

What communications protocols does LabView support?

A customer of mine is using LabView. He has asked me if I can communicate to it using a PLC. Either GE Fanuc or Allen-Bradley. I need to know what methods of communication that LabView has available to talk to these PLC's.

The short answer is: whatever protocol you want to talk...
I have developed applications talking to AB stuff, modbus (which will cover most PLCs) and even TI's old proprietry PLC protocol. There are lots of tools for making the connection in lots of ways.
What are they specifically needing--or do they know yet?

To invoke an application exe built using Labview from python.

I am trying to invoke an application exe built using Labview from python.
I am able to invoke labview vi, send and receive data. But if I change the vi to exe, it doesn’t work.

This is more of Python. I can suggest you another way, if you can do those changes to your existing code.
This is what I do: If I have to communicate between 2 different platforms I use "File" as a communication medium (Simple method). So if you want to pass data to the LabVIEW code from python, write the data to the file from Python and read the data in LabVIEW and vice versa. I generally use *.ini files for this purpose.
The best solution is the one you find it by yourself

What are the limitation of the 4 Port Gigabit ethernet Security Service Module (4GE SSM)?

I was wondering if anyone can help me out. I am trying to create a redundancy topology which require several connections to an ASA 5510. I am looking at extending the connections to my ASA 5510 appliance with the four port gig ethernet security module (4GE SSM). I am trying to find out what the limitations are on this particular module.
I have heard that there might be limitations to the 4GE SSM. Such as the interfaces on this module might process data separately from the ASA 5510 appliance. My question is does the ASA four port gig ethernet security module (4GE SSM) interfaces act as a extension of the ASA 5510 appliance or does it process and filter data separate from the ASA 5510 appliance ?
My concerns are that the 4GE SSM does not utilize all the security features of the ASA 5510 appliance, and that it just separates traffic into security zones. I interpret that to mean that each interface can be placed in a separate security level in which case has a separate security algorithm and uses the security level to force security policies. Nothing more.
My second question if relevant would be what are the limitations?
Thank you for your help on this topic.
mike

The 4GE SSM just gives you the four additional ports. It doesn't increase the processing capacity of the 5510 (a relatively low end box whose replacement - the 5515X - has been out since this past spring). It works off the same configuration script and CPU as all the built-in ports.
The only limitation I can think of off the top of my head is that members of an Etherchannel cannot span the SSM and the built-in ports.

What application will allow me to play movies with an external disc drive?

What application will allow me to play movies with an external disc drive? I recently purchased an external disc drive and when testing it discovered that it only played the audio of the DVD, not the video. Very frustrated.

Are you referrring to a commercial DVD movie, or a disk with digital movies, such as mpeg files?

What are Azure limitations for Websockets in Cloud Services (web and worker role)?

A WebSocket Server should be built on Azure platform with OnPrem connections and have questions regarding limitations for Websockets in Azure Cloud Services - web and worker roles.
Websockets can be configured for Web Sites and limitations are understood, but Azure Websites is not an option.
Nevertheless it is planned to run a web service (without UI - no web site) as a Cloud service which has secure websocket (WSS) connections to OnPrem machines. Websocket protocol is enabled for IIS8 on Cloud services web and worker roles. Azure Service Bus Relay
is not an option.
Questions:
1) Are Websockets supported for Azure Cloud services web and worker roles? we assume yes
2) What are potential limitations from Azure side to support concurrent Websocket connections? We are aware that CPU, memory etc are limitations, but are there additional limitations from MS Azure side?

Hi,
As I know, azure cloud service web and worker role support Websockets, users can connect to the role via the special endpoint, if we use Azure cloud service, I think we can monitor the metrics such as CPU, memory, etc... and scale our cloud service via these
metrics to keep the websockets working, refer to
http://azure.microsoft.com/en-us/documentation/articles/cloud-services-how-to-scale/ for more information about how to scale a cloud service.

How do I determine what applications are communicating using SMB?

I would like to try to determine if there is a way to determine what applications are using SMB to communicate to the network. Any thoughts?

Thanks Kurt. We are attempting to find the cause of the notorious two-minute spinning beachball delay. Not sure if you are aware of this problem, but it holds up Finder, Adobe InDeisgn, and other applications for two minutes while it is waiting for a response from a windows server. It shows in the log as:
1/4/12 3:29:25 PM
kernel
smb_iod_sendall: Timed out waiting on the response for 0xa0 mid = 0x3b
Very frustrating. While Lion seems to have fixed the issue for some users, EMC is telling us that Lion will not play nice with the Celerra share we use.
