CRIO loss of cummunication

This is an inquiry regarding Communication fault issue between cRIO and PC
1. We have used cRIO 9047 version with TCP/IP communication and have used LabVIEW 8.6
2. Recently we did PC replacement and upgraded LabVIEW as 2012 version. But still using cRIO 8.6 without any modification.
3. What I want to ask you is, After PC replacement, I’m experiencing disconnection of PC communication between PC and cRIO frequently.
So I'd like to ask any solution regarding this issue in case that you have any warranty experineces to solve this

It's a bit hard to determine the error without further information. How does the error present itself? Does it throw any error? Are you processing the error cluster in any way? What means of communication do you use(network variable, network streams)?

Methods to detect loss of connection with CRIO

I am developing an application with CRIO. The CRIO has an application in real time in which you are sharing a variable temperature. In my host PC I have an application that will receive this temperature and stored in a database. I need to detect the beginning of my program if present the CRIO and prompting a loss of connection and the system can not initialize.

This is the cRIO code. All it does is continuously update a variable that can be read by the HMI. It is important that this loop runs faster than the HMI loop to prevent false alarms.
The HMI code may look something like this. It is reading the variable being written to by the cRIO. If it does not change, the communication code is not running. You would probably want to do something if Comm's Lost goes true other than turn on an indicator.
There are many ways to do this and you may receive some better ideas from the forum.

Deploying cRIO as Shared Variable Engine

I am finishing up a project where a crio will be continuously recording data and the computer is running a program that will download the data once daily as well as comunicate with the program running on crio device over shared variables. Since the crio will be using a cellular modem to connect to the internet, connection loss is expected. For this reason we have made the crio serve the shared variables so that if connection is lost to the PC, the crio will continue to record data normally without problems when it writes to or reads from the shared variables.
The crio will be running headless. I built a real-time application and deployed it as startup successfully on the crio device without warnings or errors. I connected to it via font panel to confirm it started up and is working properly. I will eventually use the application builder to build an installer that will install everything needed to run the program on the PC side. However, when I open the 'Belle Glade System PC' and run it, it attempts to deploy the shared variables on the crio device. It warns me that it will close any applications running on the crio device. This is not what I want. The shared variable engine is already deployed on the crio device and the program is running. All the PC program (Belle Glade System PC) needs to do is run and connect to the shared variable engine already deployed. I am obviously doing something really fundamentally wrong here and I could use some help.

I apologize for not posting the solution to the problem.
Basically what you end up having to do is create two nearly identical shared variable libraries, one on the pc and one on the crio. The library on the PC has each of its shared variables binded to the corrosponding variable in the cRIO Shared Variable library by PSP URL (ip address and variable location). To do this, open the PC shared variable library and go to the properties of a specific variable. Check "Enable Aliasing" and under the bind to drop down menu select PSP URL. Then hit browse and find the variable on the crio. Do this for each of the variables on the pc.
This option does not seem to be 100% reliable as it has trouble detecting connection problems between host PC and crio device. This is because shared variables look for a connection to the shared variable engine. However, both the pc and the crio have their own shared variable engine running as a host so there is always a connection as far as it knows, lol. This solution worked ok for me since I could not find a more relable option.

Using fifos or indicators / varibles on cRio.

I'm currently working on the classical "remote, non-distributed measurement of voltages using the 9205 module" application. I was just wondering if I need at all to use fifos to transfer data from the fpga to the host computer on the cRio-9004. I did start out using a FIFO which I wrote to in the FPGA vi and then read it in a host vi. However extracting the array of data from the fifo using a for-loop seems to be a bit unstable with the values not always being transferred. I'm also a bit uneasy using buffers for a realtime sampling application when the language is so highlevel. So my question is:
Can I insert all my measurement data into an array and then read from the host VI using either indicators or variables, or will I run into throughput problems ?
I'm planning on using all of the 32 channels (at 16 bits) on the 9205 at a sampling frequency of 50 Hz - 200 Hz, plus some additional inputs.
Thanks,
Kevin

Hi Kevin,
You can achieve throughput rates an order of magnitude faster if you use the DMA FIFO transfer method versus front panel arrays. You will also have the benefit of DMA FIFOs taking up *significantly* less space on the FPGA than front panel arrays. Depending on what else your application is doing, you may be able to still do everything you need to through the front panel data transfer, but I highly recommend using the FIFO instead. If you're worried about data loss, just monitor the Full? output of the FIFO Write function on the FPGA to determine if any data is being lost.
FYI, we have a separate board for cRIO questions - this board is meant for the LabVIEW Embedded Development and LabVIEW Embedded For Blackfin Processors modules.

FPGA Reset during power loss? NI 9802 Module

We have recently started using the NI 9802 on a cRIO system. We are getting the error -65550 discussed here: http://digital.ni.com/public.nsf/allkb/BD118434E87B9732862575C8006FD7FB
The article says that the error can be caused by the FPGA resetting while the drive was mounted. "To prevent this error from happening in the future, do not reset the
FPGA while you have an SD card mounted, reset before you mount the card
or after the card is unmounted." Does a power loss reset the FPGA and require you to reformat the card??? We plan to use this as a remote system and power failure is possible. We would not be able to travel hundreds of miles back to the device to reformat an SD card in the event of a power loss. This can't be right. How could they sell a module that worked like that?
Also, does the card need to be formatted with FAT32 or FAT16?
[will work for kudos]
Solved!
Go to Solution.

I would like to submit a suggestion for the next version of this module. It would be awesome if in the rare but possible case of the crio losing power that the card did not become corrupt and you would then not need to travel all the way to the device and pull the SD cards out and reformat them with a pc before your system could be come operational. Like the ability to reformat at run-time would be a decent fail safe function. Even though you would lose all the data you had recorded onto the SD Card, wasting time and money, at least the entire system would not be fatally crippled by a simple loss of power and unexpected device reboot.
As it stands, even with a quality power backup battery as you have suggested, the simple possibility that you could lose power and need to manually perform a format on the SD card makes this module inferior to simply plugging in a big USB drive, both in terms of reliability and storage space. The appeal to this module, even though it could only hold two 2 gig SD cards, was its apparent ruggedness and reliability over using a usb drive.
Respectfully waiting for a new version of this module,

Unmounting USB flash drive from cRIO

Hi all,
I am using the USB port of a cRIO 9012 to save datafiles (using File I/O) to a USB flash drive.
After having run the program, I want to unmount the USB drive. Can anyone please tell me if there is a better/nicer way than just taking it out? Since this might result into losing my data if the USB drive gets corrupt (just like under Windows).
I have searched the forums, but I was not able to find anything on dismounting a USB drive on a cRIO...
Hopefully you can help me solving this (little) problem.
Thanks in advance,
Joep

Joep,
under Windows there are two scenarios that could cause data corruption on a USB-Flash-Drive:
The Flash-Drive is removed during a write operation. This potentially destroys the FAT which results in data loss. There is not much that you can do against this behavior, neither on Windows, nor under VxWorks.
With caching enabled for the Flash-Drive there is a chance that files are not written to the drive completely because some parts of it are still sitting in the PC's memory. When the drive gets removed the data is corrupt.
I don't think that VxWorks uses cache for mass storage devices at all so this issue shouldn't be relevant for a cRIO-9012, but I will double check if this is true.
Best regards,

Deploy rtexe and bitfiles to cRIO without LabVIEW Development Environment

All,
How can I deploy code to a cRIO in the field without the LabVIEW development environment? I think I can make this work via FTP for updates but for fresh installs as I'm at a loss for what files are required. There seems to be a bunch of magic going on here.
Regards,
Ken

Note, a little (good natured)sarcasm here.
No problem. Just connect it to your development system. What, you sent the application to the field? Why would you do that? Oh well, another way is to get your backup controller of the same type, hook it to your development system and load it though max. Then load the application. Then download and use the replication tools to save an image of the RT controller. Note, you have to have the same one as you sent out (you kept a spare of the RT controller, right?). Then send the files and the replication program to the field with instructions on how to use it. If you don't have a spare of the exact type, just have them send it back to you to reprogram or take a road trip, with your laptop with your development system on it.
Needs a little work, don't you think. Hopefully, it will improve. The thing about it is, the hardware is top notch. Just need a little work on distributing it. See this idea on the exchange.

They need a way to, without your development system:
1. Create an installer that will load all the drivers, os, etc that your development system would, with options for different controllers.
2. Installer for the application.

Help needed!! Why do I keep losing the connection to my cRIO?

Hi All,
I've got a real time system with the following setup.
I have got a cRIO out in the field running a real time application that accquires data from various thermocouples and sends the data to the my host computer over a wireless radio link. I am using a wireless ethernet modem with a data transfer rate of 100 kb/sec. The modem is being shared by 12 other radios also transmitting data to the host PC.
So, basically, I've got the host PC on one end and 13 field computers (one of which is my cRIO running a real-time application) on the other end. The 13 field computers are sending data to the host PC over wireless radio links utilizing a single wireless ethernet modem. The data from the 13 radios is placed on a que and the modem cycles through the que enabling the data from each radio to pass through one at a time.
My real time application is sampling the thermocouple data every 1 sec and sending it across to the host application via a shared variable
The host PC is also running an application that acts as the user interface.
My problem is this:
My system runs OK for a couple of minutes and then suddenly I lose the conection to the cRIO. Once this happens, I have to manually reset the cRIO (i.e. cycle the power back on) to re-establish the connection. This is both tiresome and inconvenient as the system needs to be able to run continuously for several hrs.
What could be the possible causes for this loss in connection? Is it possible that a clash between signals causes the modem to drop the connection to the cRIO? If so, is there a way to monitor the connection between the host and cRIO and automatically reset the cRIO in the event of a lost connection?
Any help would be highly appreciated.
Thanks,
Taizoon

Thanks for the suggestions. I think I was overflowing my FIFO so it may be a memory issue. However, it dies hard when I place a probe on my FIFO read data. Since this seems to be repeatable, NI may be able to look into it.
Anyways, I'll try some of my own troubleshooting and your suggestions then if I'm still having problems I'll be sure to check back.

CRIO 1588 Software Sync Error [swsync]

I have 2 cRIO 9074's w/ 9144 ethercat expansions. The cRIO's are 1588 slaves to a PXI-6682 GPS module.
I am getting spurious errors (2147137804 - Master is no longer sync'd with the slave device acting as the reference clock)
that appear as scan engine faults within the Distributed System Manager.

I attached a block diagram that describes the Network Topology. The cRIO is connected by ethernet cable, while sbRIO is connected by WiFi.
Both BAT-C and Open-BAT support WiFi 802.11 b/g/n.
I don't think that the problem could be that the WiFi connection get broken for some reason. Both the cRIO and the sbRIO send a continuous stream of the data to the PC. The stream (6 Mbit/s) coming from the sbRIO, that uses WiFi, arrives correctly without any lost in data also after the loss of PTP synchronization. If the connection was broken, I think that also this data stream would be corrupted.
All the devices in the network are setted with a static IP address.

How to run fsck.vfat for USB-stick during cRIO-9030 boot?

Hi all,
we have a cRIO-9030 with a USB-stick. Sometimes after power loss the USB-stick filesystem (FAT32) gets corrupted and has to be checked/fixed. How can I configure cRIO LinuxRT to do that?
I've checked /etc/fstab, but it looks that the USB-stick is mounted somewhere else. I run mount - here is the line:
/dev/sdc1 on /media/sdc1 type vfat (ro,relatime,fmask=0000,dmask=0000,allow_utime=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,quiet,errors=remount-ro)
It would be nice if I can run fsck.vfat /dev/sdc1 every boot or when an error is detected.
Thanks in advance,
Nikolai

Hi NickViz,
My name is Ed form National Instruments Technical Support, I have researched into the topic and found that it is possible to use the 'System Exec.vi' to complete the command during the initialization of your RT application.
You simply need to input your commands as a string just as you would to command prompt/terminal (depending on OS), you can also execute commands via SSH however this is one way communication between the RT application and the command shell.
I have included some links below to articles which describe the methodology as well as give some further explanation into the NI Linux Real-Time OS.

I hope this is helpful and you achieve what it is you need, do note you will need to enable SSH scripting as described in the article on using PuTTY for your Real Time device.

At a loss with phone line

Firstly I am stating for the record that I have a problem with my phone line. My broadband issues are just a by-product of the phone line fault.
This problem has been going on for several years, although, 2 months ago i made some progress.
The problem with my phone line occurs during extreme weather conditions, heavy rain or winds and as a result of it not being a permanent feature of my phone line. Over the past year, it has got a lot worse (broadband constantly dropping, struggling to be heard when on the phone), and after a lot of arguing with BT an engineer came out. Now bare in mind that the BT line tests came back as perfect and not a problem. engineer took one look at the cable coming in to the house and it crumbled in his hand. He also mentioned that he was picking something "odd" up on the line, but couldn't be sure what it was and seeing as the broadband connected that he would leave it.
Since the engineers visit, I have had an OK phone line, just a bit quiet, until 2 weeks ago. When we had all that rain. The crackles came back that evening, causing crackles and white noise down the phone line. It lasted an hour or so, but enough time to turn my 2Mbps bras profile into a 130k profile. 3 days later and we recover (even though some intermittent crackles persist). The very next day and we're downloading at 2.5Mbps, the phone rings and the crackles are back.
The next day I ring up and complain and receive the whole dialogue about changing me £120 if the engineer comes out and can't find a fault. Funnily enough, the crackles (being intermittent) are not crackling at the time the engineer turns up, however, he states "The is more noise on the line than there should be" and "I'm going to pass it over to the underground team and see if they can find where the fault is". At this point I am now feeling hopeful that finally the fault might be found....
Half an hour ago I have heard nothing, I decide to phone up and see if there is any news... No fault found and expect a bill for £120 is the response, from a very nice Indian lady who did seem to struggle with understanding me or at least hearing me. i protested and asked how could the engineer tell me one story and for me to then be told that a line test shows no fault and that I have to pay!
Where it currently stands, is that I have insisted that the problem still exists and I have been told it will be resolved between 24-48hours.
I will of course wait and see what BT come back with tomorrow, but I am at a loss of what more I can do. I work from home and having an equivalent to ISDN when I pay for broadband because the phone line keeps having a fit is getting a bit of a hassle. If the BRAS IP profile did not take 3days to recover after a bad storm, then I could cope, but I'm now been on a 130k connection for over a week now and am looking at having to pay 3120 just because I am trying to do something about it.
If I turned round to my customers and said I'd look at their issue, but if I couldn't see anything I'd be charging them £120, they'd move else where.
Any advice as to how I can take this forward?
Solved!
Go to Solution.

I thought I had better post an update and I am pleased to say that it seems it has a potentially positive outcome.
First of all the lady I spoke to on Friday got back to me yesterday to say that yet again OpenReach had investigated my issue "outside the property" and claimed to have "fixed the problem". While I am sceptical that they actually did anything (surely the broadband should have disconnected, if they fixed anything like replacing a cable, but as I am not a telcom's engineer I have not authority to make judgement), the lady implied that I had a case to dispute any charge if it ended up on my bill.
The second was a response from a forum moderator who says that after reading my posts, my email and my fault reports, they say that it sounds like this is being caused by "a high resistance fault on your line. These can be very had to get to the bottom of unless the engineer is testing the line when condition are bad" and while notes that the fault has been closed (conversation yesterday with lady from BT), they suspect that if the line does have this type of fault, then it is highly unlikely that the fault has actually been fixed and I should contact them back as soon as the noise starts up again. Oh, and they have requested no charges be applied for the visit on Thursday.
So, fingers crossed... It does seem to highlight quite a variance in the quality of customer service that you get from BT. Plus, no matter how frustrated you get, you should persevere, as there are some good people that seem willing to help and will be on your side.

At a loss. Wiring a possessed house I think! Input needed

Need some help.
I know and have done a lot of networking No pro, but self taught. Did run Ethernet of my whole house (ex wife's house now ) pre wifi days. Running wires, using switches and routers. All worked. Have down a ton of wifi - all Apple gear for myself in my location, friends and family. Good to go. I currently run a bunch in my home for iPhones, computers, netflix, itunes server, Air Video for all devices. Flawless.
So I'm not a dummy at least. So……
To my dads house. My on going project for a year. Great house. Big. Hand built back in the '50's. All plaster. Well made.
1- His office - cable modem to Airport Extreme - named BASE. Across this room, one Airport express (all AX are older g units) for the stereo from computer.
Now when I try to extend this network only for him to use his iPhone with Apple Remote to control music, I have now bought 5 Airport Expresses - the signal will not carry for more than 10 feet at best in this house (it's possessed I swear). NOT KIDDING.
I put an Express 10 feet from the office to a kitchen, why because any further I get no signal connection.
From this Express another one 10 feet for a den.
But the signal is so weak it doesn't work.
The house is plaster - I guess very well plastered and who knows what metal lathering is behind the plaster? It's a ranch.
What could possibly abort wifi signal like this. Oh, I might add, no iPhones work in the house either. We're in NY.Long Island. Major ATT signal. Nada in house. Go outside no problem.
So I'm going to tackle this again this weekend. Start from scratch. Any insight? I'm asking because I'm at a loss and think I'M NUTS! LOL
What would make wifi not carry for any distance? Lot's of windows in the house too.
I'm on the verge of telling him to have cable run another wire and modem to the other side of the house.
I'm stumped. I was going to post a few times but can't imagine why I can't get this working. Feel like a dunce.
Right now he tells me it's no connection in the den. The last AX extender not 10 feet from him.
Thanks in advance.

In addition to metal, water also will cause significant reduction in signal. The higher the frequency, the worse the problem. (One of the reasons why in the past submarines needed to surface to use their radios.) Perhaps the plaster or wood is exceptionally wet or the particular plaster they used has a high metal content. You may want to try using only 2.4GHz instead of 5HGz because lower frequencies penetrate walls better. I'm grasping for straws, but I'm not sure what else you could try short of tearing down walls.
I will tell a story of one wiring job I did. My boss gave a quote and approval sight unseen. He normally didn't do this but due to various circumstances and time constraints, he took a gamble. The job was to install a DSL modem and wireless router for a doctor's office. The modem and router were in the managers office. The reception area in the next room would have two workstations about 15 feet away, connected wirelessly. The doctor's office would get one laptop connected wirelessly, about 100 feet at the other end of the building. The building was all wood construction so no one foresaw what happened next. The manager's computer was fine since it was wired. One of the wireless reception workstations was fine with full signal strength since it was a line of sight through an open doorway to the router. The other reception workstation was working but only had 50% signal strength. (Not line of sight to the router.) The doctor's laptop had zero bars. I moved the laptop next to the router and got 100% signal strength. I walked the laptop next to the workstation with line-of-sight, and still got 100%. I walked to the other reception workstation and got 50%, same as the workstation. I walked out of the reception area turned left and started to walk down the hallway to the doctor's office. I took no more than 5 steps and got zero bars! I walked back a few steps and the meter jumped to 50%. I had to do this a few times to fully convince myself. It was only a chance conversation I had with one of the nurses who recalled that the former occupant of the office was a dentist. So we surmised that the room that the router was in might have had the x-ray machine, so they would have lined the walls with lead or whatever. In any case, we ended up having to pull wires. But we learned that regardless of what it looks like on the outside... But this does sound quite similar to your experience.
There's also the time that my coworkers found that the whole wall was 1/4" steel plate. The walls were covered with drywall so we didn't know it was there until we ruined a half dozen drill bits. It seemed like it was armor plate steel. We think the building used to be a indoor gun range or something. And there was the time that we encountered hardened concrete walls at an office using a former military building. Fortunately neither of those had Wi-Fi but we likely would have had signal problems in both cases. It taught us that we can't assume and needed to do a thorough inspection ahead of time.
So while I don't think the house is possessed, I do suspect that the original builder used some funky local material. Maybe he was a conspiracy theorist and has tinfoil in all the walls.

At a total loss how to export IPhone 4 video To My PC

I've read and posted in various threads and looked all over the net. I admit I'm at a total loss as what I'm doing wrong at this point.
I want to take the video from my Iphone and move it to my PC so I can upload it in HD to youtube.
I've made sure to make sure my phone doesn't sync right away, gone to the my computer and click on my phone (shows a camera), then copy and paste or drag. When it moves it over it say 0 bytes.
I'll even post a link a buddy of mine sent and if you look at step 9 it says the videos should be quick time files. Mine says nothing where it says file types.

Is there something I'm doing wrong? Like I said I'm at a total loss.

I'm not sure if this will help you, but I ran across the same issue. When I tried to pull the videos off the phone in windows, it would hang during the transfer, or not transfer at all. My photos and videos are kept on an external drive and I was trying to copy to that external drive. I copy and pasted the videos into the pictures folder on my PC (instead of the external drive) and it worked like a charm. Once that was done, I just had to drag and drop into the external drive.
I hope that helps!

T500 performance loss and restart issue after low battery shutdown

Hi,
Some days ago I experienced a significant loss in performance of my T500. Unfortunately it seems to be a continuous loss and the games I play, e.g. empire total war that did run ok before are nearly unplayable at the moment.
Additionally, when the computer shuts down due to low battery, it no longer manages to resume windows but always crashs during reboot (black screen and hard disk symbol is moving, no other activity for 10 minutes)
I am working with the standard vista installation and installed all automatic updates, but also every time when I shutdown the computer, no matter how long it has been running (even after 1 minute and after a rebooting 3 minutes ago), the red shutdown symbol in start shows that an update needs to be installed.
any ideas?
Many thanks in advance !

Well, the problem, seem's to have reoccured: Battery ran out (even the indicator leds on the side didn't show any life), Time reset to 1.1.2001, again some rebooting and setting the time again...
Is this a sign of a degrading battery health status?
It looks like reseting the SMC didn't help after all.
