Real-time and Developement System

I have a very premitive question. what is real-time OS? what are differences between real-time and Developement labview.

Real-Time in general is not about speed, it's about guaranteeing, that a specific function will be executed within a specified time window.
Imagine a car with some sort of fieldbus. You want the brakes to be working at any time within a time limit (say, 1ms). That's Real-Time.
Windows for example uses some sort of scheduler to distribute CPU time to the different threads with a granularity of - i think 1 ms. So each thread gets 1 ms, then it is interrupted and the next thread gets its 1 ms. Of course there are priorities which thread gets a little more time (or more "slots") and which thread gets less. BUT: You cannot tell in Windows, that your application will execute in a specified time window - at any time, it can be interrupted and therefore delayed and theres nothing you can do about it.
Real Time OS make sure, that - if some specified event happens - it will be executed within a specified time window.

Read data in real time and save as an excel file

Hi,
I want to write a LabVIEW progarmme which able to read data in real time and save it as an excel file from Varian Vacuum muli-gauge.
It is using RS232 port.
Can anyone give me some examples or point me in the right direction?
I am a beginner of LabVIEW. Hope anyone can help me.
Thank you very much!!
Joanne

Thanks for your reply.
I just use MAX to verify that the rs232 port is operational.
However, there is an error (please refer to the attachment).
One possible reason is in MAX I am trying to do the default command *idn? ...but it doesn't work.
I read the vacuum multi-gauge manual but I don't know which command should I use...
I attached the manual and can you tell me which command should I use?
Or can you tell me other possible reason for this error code?
Thank you very much.
Joan

Service product replication for test and developement system

Hi Experts,
In our scanario service product is created in production system and later manually created in test and developement system.
Is there is any standard function module avilable to replicate the product master data into test and developement system
Or Is it possible to use the middleware functionallity to replicate the service product details.
Please advice on this issue.
Thanks,
Senthil .R

You can use the FindFile method in the TS API:
FindFile Method
Syntax
Engine.FindFile ( fileToFind, absolutePath, userCancelled, promptOption = FindFile_PromptHonorUserPreference, srchListOption = FindFile_AddDirToSrchList_Ask, isCommand = False, [currentSequenceFile])
The function itself returns a boolean which indicates if the file exists or not.
Then just use a Call Executable step to run command line string to delete the file.
Hope this helps!

Synchronize system time and set system time zone in SAP

Hi,
How to Synchronize system time and set system time zone in any SAP system?

Nabarun -
Setting of the system time may be different depending on your enviroment and systems. (Windows, AIX, etc)
Windows enviroment you can use a time server or net time command, I believe its simialr with UNIX but I do not know that command.
Setting the time zone in SAP is done through the IMG in client 000. You can get there with transaction SPRO.
Once in the IMG, navigate to:
SAP Netweaver
General settings
Time Zones
Maintain Time Zones (here you can define the time zone settings/rules)
Then go to:
SAP Netweaver
General settings
Time Zones
Maintain System Settings
There you can change the time zones for the system.
Hope this helps.

Labview real-time and simpowersystems toolbx from matlab

Hello,
I have a simulink model built with SimPowerSystems toolbox. I want to run this model on a RT target which is a desktop ETS in this case. I follwoed the instructions on how to create and deploy the DLL. There are two problems I am facing--
1. The host screen grays out even though the mapping is correct. (This is verfied by using a similar working file.)
2. The RT target hangs and then the connection is lost. I don't get any error message and after some time as there is no communication, I get error 66/63 etc network related error.
The questions are:
1. Is SimPowerSystem toolbox supported in SIT? ( I read that the SimMechanics is not supported.)
2. Is there any limitation on how many nodes I can use so that the RT system can run the model without getting hung up.
The versions I'm using are:
LabView 8.2, SIT 3.0.2
Matlab R2006b, SIMULINK 6.5, Real-time workshop 6.5
microsoft visual C/C++ 6.0
Please let me know ASAP if anyone has faced this problem before or if someone can answer my questions.
Thanks,
Gayatri

Signals also can be removed when the code is generated and compiled due to optimizations. Right clicking on a signal and making it a testpoint forces RTW to include that signal in the compiled code signal list. The appropriate discussion is posted below.
Models Using Signal Storage Reuse, Block Reduction Optimization, or Virtual Blocks
Mappings might appear invalid if the model uses either Signal Storage Reuse or Block Reduction Optimization. These items are options you can set in the Simulink application software to reduce the memory footprint of the model. Disabling these options for the entire model makes all signals available for probing but increases the memory footprint of the model. You can mark individual signals as test points to maintain a reduced memory footprint while keeping certain signals available for probing. To make this change, load the model in the Simulink application software and perform the following actions:
For The MathWorks, Inc. MATLAB® application software release 13, right-click a signal and select Signal properties from the shortcut menu. Place a checkmark in the SimulinkGlobal(Test Point) checkbox and click the OK button to save changes.
For the MATLAB® application software release 14 and later, right-click a signal and select Signal properties from the shortcut menu. Click the Logging and accessibility tab, place a checkmark in the Test point checkbox, and click the OK button to save changes.
Note If you previously converted this model to a model DLL, you must convert the model to a model DLL again after marking signals as test points.
Similarly, you might not be able to probe signals from Virtual Blocks such as Mux, Demux, Bus Selector, and so on. Marking signals from these blocks as test points makes the signals available for probing.
Refer to the Simulink documentation for information about Signal Storage Reuse, Block Reduction Optimization, Virtual Blocks, and test points.
Models Using Inline Parameters
You might not be able to manipulate model parameters if that model uses the Inline parameters option in the Simulink application software. This option writes a constant value to each model parameter. You must launch the Simulink application software and disable this option so the Simulation Interface Toolkit can manipulate the model parameters.
Refer to the Simulink documentation for information about inline parameters.
Models Containing Linked or Masked Subsystems
You can create mappings to parameters and signals of masked subsystems. However, if a subsystem is linked, or linked and masked, any mappings to parameters and signals of that subsystem appear invalid. Refer to the Simulink documentation for information about linked and masked subsystems.
Subsystems without Parameters or Signals
If a model contains a subsystem that does not have any parameters or signals, that subsystem appears in the model tree when you create mappings. However, you cannot create mappings to/from that subsystem.

Viewing data in real-time and saving on-demand - USB4000 Spectrometer

Hey,
I am trying to create a program with a USB4000 Fiber Optic Spectrometer to allow the user to view the data in real-time on the front-panel, yet to be implemented, and also be able to save the data to an excel datasheet, or if another format if more appropriate. I am reasonably new to LabVIEW and have limited experience with saving data to excel.
I am currently trying to build upon one of the example VIs given with the drivers. Currently the VI produces data like the following:
Wavelength (nm) Spectrum Data
xyz xyz
xyz xyz
xyz xyz
xyz xyz
I want my VI to continue to append to a new column every iteration but I think due to me inputting an array of dimension size 2 it can't but am unsure how to get around this?
The current VI starts off by creating the Headers and then appending to insert the spectrometer Data.
Any help would be much appreciated, apologies if I am unclear about anything.

Ok, a couple comments. First, it is easier to build a 2D array by appending rows and then transposing the array before saving it. Also it is much more efficient to preallocate the array if you know how many columns the data is going to have.
Second, adding a new column or row isn't a problem because an additional column (or row) doesn't effect the number of dimensions.

LabVIEW Real-Time and Remote Front Panel MemoryManager.cpp line 437 error

Hi all,
I'm using a smartcamera (NI 1742) with LabVIEW Real-Time 8.6.
When I look at the Front Panel with the web browser and I close the browser or I Stop the executable, I always get this error: MemoryManager.cpp line 437. I've checked if someone else had this error, but I guess I'm the only person who got this error. I saw someone who had the MemoryManager.cpp line 406, but mine isn't on this line.
The application works well, but when I got the error, I need to reboot the smartcam to get it works. In my application, I use the Modbus library and I read/write binary file in the hard disk of the smartcam....
Anyone knows the solution?
Thank you very much
Stephanie

Hi again,
Still didn't find the problem on my side. Here's a picture of my code. If I put the code surrended in red at place (1), I don't get the error, but if I put the code at place (2), I get the error. Why oh why....?
I get the error when I close the browser or click Back button of the browser or Stop the application with the red dot or stop the application with the Quit button on my front panel.
This morning I found a post on this forum about getting an error using Property node and Remote panel (http://forums.ni.com/ni/board/message?board.id=170&message.id=252705). I did what they suggest: wire the property output to an indicator and it works (disable "Enable automatic error handling dialod" didn't work... I don't know why)... until I put extra code in my VI.
I really need help please!
Thank you
Stephanie

Labview Real-Time and CompactRIO questions

Hi
everyone! We have new troubles about CompactRio and Real Time module:
-We want to
translate into real-time module a VI we have done with Labview 8 .2. In order
to do that we have discovered an option placed in Project Explorer (Tools->Real-Time
module->Communication Wizard) that seems to translate automatically into Real-Time
language. Is it true?
- If it was
true we would want to do a transmitter VI in CompactRio (RT target) and a receiver VI in the Host. But the
Communication Wizard creates a VI in the Host and a VI in the RT target (in
Real Time language) for each VI we enter to translate ( so we obtain 4 VI’s in
the same project , two of them as transmitter, and two of them as receiver)
-We have
tried to deploy some VI’s to the CompactRio and we get always an error.
CompactRio’s configuration is allright and it is well recognized by MAX. Why
does the error appear, and how can we work it out?
We
need to configure the Serial Port placed in CompactRio in order to adjust some
features, such us bauds value. MAX recognized the CompactRio’s Serial Port, but
all the opctions to configure them are disabled.
I hope you
can answer these questions. Thank you.
