Software protection with real time clock

I'm trying get a secure real time clock information for licensing purposes ,I tried hardware dongle like hasp4 with RTC but I was not able not interface the dll and kept coming up with errors.Can anyone suggest a better of getting real time clock information or any available product which I can use.
I even thought of using the system clock but it's doddle to reset the system time.
Help is much appreciated.Thanks in advance

One possibility might be to force the computer to access an external time server of your choice and check the time from there.
This example shows how to read the time from a NTP server using LabVIEW.

Problems with my Mobo - Hangs at "Testing Real Time Clock" - Whats up?

Specs:
MSI K7 Master - MS-6341
AthlonXP 1800+
512 PC2100 DDR
40 gig Maxtor or Seagate 7200rpm, 2mb cache - tried both
Pine 56x CD Rom
eVGA GeforceFX 5200
Generic 420watt PS AND Antec TruePower 430 watt PS - same results
Alright, I can access the BIOS, etc. but after the first startup screen (with ram, processor type, IDE config, etc.) the screen just has a underscore blinking at the top left...and the error system says Testing Real Time Clock - Ive basically narrowed it down to the IDE connectors since I can unplug the hard drives and it gets past that section and asks for a boot drive - anyone have similar problems? I know he board is old but its for the family and Im stuck right now and I got some anxious members of my family wanting to know whats up with the system - any help will be appreciated...
It should be noted that I was able to install/run Windows for a couple of days - then I got stability problems which was from the BIOS overclocking my ram past spec but I fixed that and Windows was fine but now I cant boot back up and it cant be virus or bad hard drive because Ive tried more than one - some people who also have this problem can sometimes boot to their OS but its usually not the case...thanks again for the suggestions..
Things Ive Tried:
Replaced the CMOS battery
Cleared CMOS
Change IDE channels
Tried just the hard drive
Removed jumper from hard drive
Cleared CMOS
Reseated the ram
Reseated Video card
Cleared CMOS
If someone can find a working solution for this, Ill give them something in return - like some DVDs or cash or something, I really need some help..
- Adam/vicks

No problems with the mobo physically - I got it new from a trusted guy on some forums I goto (anandtech) new from an RMA - still sealed...
I have it running....again....it doesnt like that 1st IDE channel for some reason - Ive restarted/rebooted a few times and nothing has happened so hopefully its fixed but still not cool - Im almost 100% sure it will happen again...

Error: 0271: Real Time Clock Error - Check Date and Time settings.

Hello all,
I have lenovo T430s laptop that is configured with Bitlocker encruptions and TPM PIN entry. I don't think that has anything to do with the error msg I am getting but here it is. Error: 0271: Real Time Clock Error - Check Date and Time settings.
Press Esc to continue or F1 to enter setup. I am unable to get into BIOS or even the login screen for Windows 7.
Any advice would be appreciated.

Thanks to everyone for the help. Just want to close this out. I had a IBM/Lenovo technician here today and he replaced the CMOS battery. Upon the change, the computer is fine being reconnected to the dock (the three times I tried it). So it has been resolved with the battery. Surprised by the incompatibility claim because I am not having issues now. Wondering if it's just a USB 2.0 vs. 3.0 thing (and Lenovo trying to sell more peripherals, of course).
Thanks!

[Solved] QJackCtl won't start in with real time.

Hey all,
I'm having a problem with QJackCtl, I got my version from Extra. The problem is that for some reason Jack won't start in real time mode using QJackCtl. Real Time is checked and marked under the set-up tab, but that little piece of info doesn't seem to make it to jackd. If I start Jack through CLI it works with real time, but not from the GUI.
I figured this out by starting JACK from the command line and then starting QJack. When I would do that it would be running in real time just without the rest of my settings (buffer,periods,sampling rate, etc). So in my head there's an issue with QJackCtl. I've tried to find a solution, but I can't seem to find one. This isn't the first time I've set JACK up on a system, but this is the first time I've had this problem.
The rest of the system is set up and ready to go. Rt Kernel, limits.conf and all other tuning is done.
Is there something I missed when setting this piece of software up? Any ideas?
Solved Edit:
Okay, so right after I posted this I got a crazy idea. When you enter setup in qjackctl on the first page there's a box for server path. The path defaults to "jackd". On that line I added "--realtime", so it looked like a basic CLI start-up of JACK and now it works!
So, if anyone else has this problem go to the Setup tab, in the setup window on the line that says Server Path it should look like this:
jackd --realtime
It worked for me and I hope it helps somebody else out.

Which volume? Assuming you're on the most common usecase (single hw audio device) then whatever command line you use (amixer for example) it'll work fine, it'll control the volume of the device rather than the pulseaudio plugin (so other playing apps get affected as well, which is probably what you want). The 'global' volume so to speak.
For multiple hw audio devices it gets tricky though.

X121e randomly wake up from suspended status and real time clock error

Hi all
Previously I considered my x121e suffer from overheating issue and causes real time clock error (RTC). However, after more testing and investigation, I believe the problem is related to other hardware issues and I like to hear people opinion before sending the laptop back to Lenovo.
The machine goes into suspend status either pressing the power button or closing the lid from Windows7 (clean install) without problem. However, it would wake up itself randomly, "beep" twice and screen shows RTC and CMOS checksum error. This happen more often when I am holding the machine (i.e. some movement/vibration). I wonder:
- Is it the RTC battery problem, cause the RTC to wake up the machine?
- Other hardware failure?
The laptop has a clean OS installed/recovered. Latest 1.16 Bios installed. No USB or memory card attached. Ram replaced and not the cause.
Please advise
Howard

Hello,
I am unsure; you would have to contact Lenovo directly and find out how they handle this situation. They may want the ThinkPad X121e back so they can run thorough diagnostics on it, just in case the problem is something else. That way it gets fixed the first time.

RMAN in active data guard with real time apply ON without a catalog DB

I would like to know whether I can take RMAN backups (both level 0 & incremental) in active data guard with real time apply ON without a catalog database. version is 11.2.0.3.2. Will it make difference in the control file of standby syncing with primary? Can I use these backups on primary to restore and recover the database(including control file backup)?

Thank you very much msberg. Could you please answer the below queries as well?
Should I cancel Real Time Apply before starting RMAN?
Will it make difference in the control file of standby syncing with primary? Is it possible to use these backups on primary to restore and recover the database(including control file backup)? If possible, how will I do that?

RAC with real time knowledge

Hi, I'm interested in learning RAC and dataguard with real time knowledge......... please help me finding some training institution or peoples with real time knowledge
Thanks

The term "+real-time+" has a very specific meaning in Information Technology. See http://en.wikipedia.org/wiki/Real-time_computing for the basic details.
Oracle RAC is not a real-time database.. and nor does the "real-time knowledge" make much sense IMO...
Always difficult to get to grips with the nuances of the English language where it is your 2nd or even 3rd language. But it is important that we speak the same language and understand the same terms and concepts, in Information Technology.

B2MML with real time data

Hi All
I want some B2mml files with real time data.
So exact( maintenance infromation and Production) B2MML that is coming from MIS.
So if anyone have some information regarding this please tell me.
Thanks in Advance
Ramshanker

Hi, Ramshanker.
In the cases where the plant system is directly delivering B2MML documents (such as with certain products from Wonderware, Siemens, and some others), using the data in xMII is quite straightforward.
1) If the B2MML message is not "standard" B2MML (be aware that very few plant vendors use the baseline standard - most have a number of specific extensions), you can add the vendors' schemas or B2MML example documents to xMII by adding them to a ReferenceDocument folder on the server.
2) In xMII BLS, create a transaction (let's assume you called it B2MMLHandler) with one input parameter, of type "XML" (let's assume you called it "B2MMLDocument"). Add a "ReferenceSchema" or "ReferenceDocument" action, and configure it to load the vendor's B2MML format. Use the "assign reference document" menu option to assign this format to the transaction input.
3) You can now use the B2MML document to perform analytics or to map from the B2MML document into any RFC or BAPI calls or ESA service calls from within BLS.
4) The plant system system should "post" the XML data to an xMII transaction using the "Runner" URL as in:
http://<yourserver>/Lighthammer/Runner?Transaction=B2MMLHandler&InputParameter=B2MMLDocument
Of course, if the MES system isn't capable of posting the documents and they are available on the file system, you can use the xMII file actions (or remote file access via FTP) to access and load the B2MML documents, perhaps at a scheduled interval.
Hope this helps get you started in the right direction.

Rick Bullotta

Real Time Clock Error - Check Date and Time settings, System CMOS Checksum bad

Hello everybody,
Can help anyone to resolve my problem.
I have an Thinkpad W520 (42823FG), BIOS 8BET60WW 1.4 When I disconect AC power and remove battery and connect again, I see this message on screen:
"Real Time Clock Error - Check Date and Time settings, System CMOS Checksum bad
Press Esc to continue or F1 to enter Setup"
Is this a system board problem or CMOS battery problem ?
Thank you

Hello and welcome,
It's probably (hopefully) just the CMOS battery. The easiest way to find out is to just replace that battery.
Page 85 of the Hardware Maintenance Manual:
Hardware Maintenance Manual
Here's an example of the battery. I'm not recommending (or not) this vendor:

Configuring Vision Builder demo software with real time EVS 1464

whe i tried to configure the Vision Builder to real time EVS 1464 it didnt se the MAC address of the EVS
Solved!
Go to Solution.

Hi Frank Noe,
Have you connected the device and set it up as specified in the manuals? A good place to look to ensure you have taken the proper setup steps is the 1464 RT's getting started guide. Pay particular attention to the steps listed on pages 8-12. If you have everything connected and setup properly, and are still encountering this issue, take a look in the 1464's user manual in appendix D. On pages D-4 and D-5, the manual lists troubleshooting steps for the device not being listed as a target in VBAI. Hope this helps.

Issues with Real-time Playback?

Hello,
I am working on an animated film and I am having trouble getting my footage to playback real time in Premiere 6. It is making it impossible to edit.
It plays choppy. Will stop on a frame. Doesn't catch up on the edits.
Here are my computer Specs:
MacBook Pro
2.5 ghz intel core i7
8 gb mhx DDR3
AMD Radeon HD 6770M 1024 MB
OSX Lion 10.7.5
Sequence Specs:
24 fps
1980x1080
spuare pixels
progressive scan
24fps timecode
48000HZ
Footage Specs
24 fps
1980x1080
h.264
file size between 2MB - 300KB
Sequence length 4:18
I have trolled all of the forums to see if there was anything to change to no avail:
I tried both setting the Project set to MPE with GPU amd MPE with software. No difference either way.
Playback resolution is at 1/4
I've closed all applications.
Optimized my drive.
Restarted.
Updated to 6.0.2
Anyone have similar issues? Any ideas on my set-up?
Thanks,
sasha

I am sorry. I actually posted other questions here and I have always put my
computer info at the end of my questions. Yesterday I was browsing around
and I noticed that under the profile you created a specific place for the
computer info. So I thought that perhaps it would be the proper way to do
it . Apparently I did the vwrong thing. Also to ask a question on the web
is something that we all do without thinking anymore. Everything is free
and we take everything for granted with no intention whatsovere to take
advantage of anyone and neither did I in this instance. My apologies. I
will follow up with my computer specifications tonight when I get home from
work. Thank you.

Compatibility of Pattern I/O with a PXI-6533 card with real time application

Hi,
I use a PXI-6533 card on a chassis with a PXI-8145 RT controller. I want to acquire 32 bits of data with this card at 1,25 kHz. These data are generated by an external FPGA card together with a clock signal. Referring to the 6533 documentation, a simple way to synchronize the acquisition is to use pattern I/O, entering the clock signal on the REQ pin. I tried the LabVIEW example Cont Pattern Input.vi. It seems to go well, but it does not work when I change this .vi priority to Time-critical or any higher priority than normal. Is there an incompatibility between this type of acquisition and real-time ?

Hi,
Sorry for this late answer, I effectively added a �wait until next ms function� in the time-critical loop and it seems to work. In fact, I don�t see exactly how, but it works with 1ms up to 50 ms.
Nevertheless, the next step is to add the content of this example in a more complex system with a communication loop to transfer the acquired data to the Host PC. I already have such an architecture, with a �time-critical priority� .VI to read the data at 1.25 kHz and a RTFIFO to transfer them to a second �normal priority� .VI loaded on the PXI, that ensures a TCP communication with the HOST PC. This architecture works correctly on another application with an internal clock, BUT doesn�t with this example, even with your solution.
In
fact, it seems to work when I put the two .VIs loaded on the PXI in �normal� priority, but with a tremendous jitter (the frequency varies from 1 to 2 kHz) and a scan backlog that gets full very fast. Then, the PXI crashes as soon as I change any priority.
You�ll find attached these three .VIs and I hope this could help to find a solution.
Cordially
PS: Since we started this thread, I�m in relation with NI Support France on that subject. Nevertheless, we haven�t found any solution yet and any new idea is welcome !

Producer/consumer architecture over network variables with Real-Time target.

Hi all,
I am maintaining a producer/consumer data acquisition program to be deployed on a real-time target. The main code is deployed to and run on the real-time target during experiments, but was having trouble because the program was originally designed to write all experimental data to disk on the real time during acquisition, which puts the whole experiment at the mercy of the hard drive. I am now trying to rework the code so that the host takes care of logging, so that my time-critical loops don't have to wait.
I am currently using LabVIEW 8.5
I have two questions:
First, how can I programmatically call the data-logging subvi on the host so that it runs in parallel with the main vi which runs the experiment and collects data on the real-time? I have attached the test code that I have been working with to figure this out, but it does not run the logging vi continuously in the background. I am aware that there is better functionality for this in newer versions of LabVIEW, but I would prefer not to upgrade unless there is no other option. I would like to be able to run my data-generating vi and have it start the data logging remotely.
Second, is there a way in the host VI to read values off the network variable using an event structure rather than polling it for updates?
Any help would be sincerely appreciated!

VI server
Mark the target VI as served on the machine on which it will execute and use VI server Call by reference to invoke the served VI.
This used to be taught as THE way to communicate syncronously with an RT app.
