Does labview provide epoch time converter support?

Hi,
My product creates a data log file with time stamp. The time stamp is of the epoch format. The system is based on the linux. So I assume that this time stamp is a unix based format. How should I convert this time stamp data to the UTC format in labview?
Regards
Gopal

LabVIEW's time stamp is the number of seconds since 00:00:00 01/01/1904. Unix (and hence I presume Linux) time is the number of seconds since 00:00:00 01/01/1970, all times specified as GMT. So all you need to do to a Unix timestamp is to add the number of seconds between these two moments in time to obtain the LabVIEW timestamp.
You can generate this number by using Date/Time to seconds, giving the input as Day 1, Month 1, Year 1970, and all others zero. It gives 2082844800
Make sure that you treat the numbers as U32, as the current date/time exceeds the maximum value for as signed 32 but value.

Does LabVIEW under Mac OS X support the PCI-MIO-16XE-50?

Or indeed any PCI DAQs for that matter?
Thanks!

To the original question: No. However, we have written control and
display applications on Mac OS X that access PCI-MIO-16XE-50 cards
from other computers in an embedded configuration. The Mac OS X box
acts as a UI controller interface and also shows the data in real
time. It can also multiplex across several distributed controllers.

How to convert Epoch time to Datetime (YYYYMMDDHH24MMSS)

Hi,
In our Oracle db, Datetime is stored as Epoch time (seconds since january 1st 1970). To get a readable date, I have converted those fields as followed:
TO_CHAR(TO_DATE('19700101000000', 'YYYYMMDDHH24MISS')+((DATE_FIELDS-18000) /(60*60*24)),'YYYYMMDDHH24MISS')
Result ex: 20100830135422
The problem is that the resulting fields are in VARCHAR2 instead of DATE so it causes issues in SAP BW reporting development. BW developpers can manage something to make it eventually work but I would like to correct this at the source if it is possible.
I have already tried to add another "TO_DATE" function at the beginning of the previous expression but I get a date in "DD-MMM-YY" format as a result even if I have forced another date format.
Any idea on how I could solve this?
Thanks a lot
Pascale

Ok, there is clearly a disconnect here.
Oracle stores dates in a DATE datatype. This means that, internally, it will store enough information for a 4 digit year, a month, date, hour in 24 hour time, minute, and second. All that information is stored in the DATE datatype inside the database, but, it's stored in an internal format, that has nothing to do with what it will look like when you print it. When you want to retrieve it, Oracle must have a date format string, so that it knows how to display that information. If you do not provide a date format string via the TO_CHAR() function, Oracle has a parameter called NLS_DATE_FORMAT that provides the default format to use. If you have not set the NLS_DATE_FORMAT, it defaults to DD-MON-YY.
So, having said all that, what are you actually trying to do?
You started with this expression:
TO_CHAR(TO_DATE('19700101000000', 'YYYYMMDDHH24MISS')+((DATE_FIELDS-18000) /(60*60*24)),'YYYYMMDDHH24MISS')How is that expression used? In a SELECT statement? Then you probably want it the way it's written above. In an INSERT statement? If so, then if the datatype of the column you're inserting into is DATE, then you probably need to eliminate that outer TO_CHAR conversion, so that the expression returns a date that can be inserted into DATE column.
Tell us more about what you want to do, and perhaps we can offer further help.

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).

How will the Time Capsule support IPv6 and coop with the new emerging security threats that will emerge due to the new technical possibilities that IPv6 provide?

How will the Time Capsule support IPv6 and coop with the new emerging security threats that will emerge due to the new technical possibilities that IPv6 provide?

Cross your fingers and hope.
Obviously if there is any big or known threat Apple will send out a firmware fix.
But the TC is designed to be end user simple device. It has no firewall that is visible at any rate. I don't know that it truly doesn't have a firewall but it is not part of the end user controls.
IMO if you have major security concerns that go beyond end device firewall, which is where Apple do put most of the security, since firewall in the router is plainly not a stop to anybody deliberately downloading an infected file or website, and most end users.. do not want a firewall that prevents them using the web like a business does, where only certain ports are allowed. Everything else tough luck.. you are not allowed to use it. Then TC is unsuitable for you anyway.. buy a proper firewall appliance.

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 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 DNG Converter support CFA DNG for X-Trans files?

Does Adobe DNG Converter support the X-Trans sensor layout from ie. the X100S? Can converting an X-Trans sensor RAF file to to DNG result in a file that is _not_ in any way demosaiced and/or linearized?
If DNG Converter truly does support conversion of X-Trans to CFA DNG files, how can the resulting files be so much smaller (when not linearizing or ticking lossy compression of the DNGs)? The RAF files are all around 32 MB, while the DNGs are around ~23 MB. Is it only a matter lossless compression, or is the mosaiced data in some way altered?
If DNG Converter does support CFA DNG for X-Trans, at what DNG Converter version did you first implement support for the X-Trans sensor layout and conversion of X-Trans data to CFA DNG files?
These are important questions that I'm having a hard time finding answers for. I'd appreciate answer to any (but preferably all) of the questions.

Converting EPOCH time stamp to time stamp in Oracle

Hi,
I need a help regarding how to convert the epoch Time stamp, to oracle date and time format.
for example,
for epoch time stamp:1204104116656
the time stamp should be :2008-02-13 12:43:00.351
Thanks in Advance
Basil Abraham

Are you sure you've got the right timestamp? Assuming this is a standard unix epoch time stamp with the epoch date starting at 1970-01-01 UTC the interval between 1970-01-01 UTC and 2008-02-13 is 13922 days, but your epoch timestamp divided by the number of miliseconds in a day 1204104116656/(1000*60*60*24) comes out to 13936.390... days a difference of 14 days 9 hours 21 minutes 56 seconds and 656 miliseconds.
Anyway to convert you need to convert your epoch date into an interval and add it to the starting epoch date (as a timestamp):
select to_timestamp_tz('1970-01-01 utc', 'yyyy-mm-dd tzr')+
numtodsinterval(1204104116656/1000,'second') dstamp

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.
Regards,
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.
