CompactRIO DataSocket error 1181

I have a cRIO 9073 and am trying to read from a web page using DataSocket. I have installed the datasocket for labview real time 5.0.0 to the cRIO but i get the error message 1181 occured at datasocket read Protocol not recognized by LabVIEW. I need to read the online file, I need to pass data to the cRIO. So either i need a fix or a different way to read the web page to a string or array. Thanks
Solved!

DataSocket for Real Time only supports the protocols listed here, which unfortunately does not include http. You may want to look into using LabVIEW’s HTTP Client palette instead.

Datasocket error when network cable unplugged

Hi,
I'm having problems with my datasockets. I have applications running on multiple computers, which publish data to a datasocket on the localhost. Whenever we unplug a network cable, or the network goes down, the datasocket write function reports the following error code: -2147014843 in Datasocket Write.
I can't find any information about this datasocket error code. Can anyone give me advice on how to find more information about this error code?
The result is that whenever there is a network issue, we need to go and resolve it, then we need to log onto each computer (25+) to get the datasockets working again.
Also interesting to note is this problem has only presented itself since upgrading the computers from NT to Win2k & WinXP.
Thanks for any help that can be given.

Hi again,
Just in case anybody else looks here, and have a similar problem...
The error code we saw was related to the networking functions of Windows. In particular, the reason we did not see this problem in Windows NT, but it started appearing in 2000/XP, is the media sense functionality of Windows 2000/XP. In 2000/XP, if there is no connection detected, the OS dumps the IP stack, and with it, the IP address. As a result, when we try to write to a datasocket on the computers IP address, Windows returns an error, since there is no IP address anymore.
To resolve this issue, we turned off Media Sense on the affected computers. We followed the instructions on this page:
http://www.windowsnetworking.com/articles_tutorials/Disable-Media-Sense-TCPIP-Windows-XP.html
Now, when the network drops out, we keep the same IP address, and so the datasocket can continue to write to the local computer, without any problems.

Slade Squire

OPC client using DataSocket - Error 0x80040154

hi everyone,
i am setting up OPC comm between LabVIEW 2010 and SMA OPC Server. they are in the same machine. i have followed all DCOM settings there, and i can view and write data of SMA OPC through MatrikonOPC.
then i start using DataSocket Select in LabVIEW. while i run the vi I can see a pop up window showing all running OPC servers in that PC. but while i double-click my SMA OPC server or other OPC servers, i always get this error -
error code - 0x80040154,
Class not registered
The server is not properly registered on the machine.
Try running <server>.exe /RegServer for an executable server, or RegSvr32.exe <server>.dll for an inproc server.
i tried following the instruction of last line, but never succeed.
Looking for any kind of help. Thank you very much.

Hi Daniel,
Thanks for submitting your question. This error occurs because your OPC server is not registered. For example, here is an article that explains how you can register our FieldPoint servers:
How Do I Register an OPC Server Without LabVIEW?
http://digital.ni.com/public.nsf/allkb/662939B4C756729286256C24005530B9?OpenDocument
Yours might require a different method so it is worth contacting the manufacturer of your OPC server and ask them how you can register your server. Uninstalling and reinstalling the OPC software will sometimes take care of any registration issues.
I also thought you would find these links useful:

OPC DataSocket error 42 in writing negative values

I was playing around with OPC and using the DataSocket pallete. Although I've used it reliably for a while and am content, I was baffled by one error. I was hoping someone could explain why this error occurs or how to solve it.
In the NI Distributed System Manager I've created an Shared Variable of the type single, with Read/Write access.
Problem
When writing a value less or equal to 0 to an OPC URL, I get an error 42. When using the equivalent PSP URL, I don't get it.
Using this VI snippet code.
I get these paths and errors:
This error 42 comes for all values below zero and for zero. For all positive values I don't get this error. What's the reason for this behaviour? In my humble opinion this is not wanted behaviour, as OPC tags should accept the whole value range of the single.

White spaces are allowed in OPC URLs, so that cannot be the issue.
I've tested with another LV2013 computer and NI Distributed System Manager 2013 and got the same errors. However, when I tested it on a LV2012 and NI DSM 2012 it was all working. Quite strange.
Now I'm wondering if it's something local or that the bug was introduced in the 2013 distribution and if it has been solved in the 2014 version ...
Could someone test it on LV2013 and/or LV2014, just to check if the problem occurs for other installations in LV2013 and if the problem has been solved in LV2014? Please indicate LV version and DSM version.

CompactRio software error, safe mode, Staus light 4 flashes per second

My cRio 9204 was running fine for the past weeks. But this saturday it stopped working and Status light showing 4 flashes per second.
I opened MAX, and the cRio was in safe mode (sofeware error)
I tried to reformat the controller and reinstall the software. It did not fix the problem.
After I reformatted the controller, the Status lights were flashing twice per second (The controller has detected an error in its software)
After I installed the software, the Status lights were flashing 4 times per second (The controller software has crashed twice without rebooting or cycling power between crashes).
the Error log showed the memory was mostly free, so it was not memeory problem.
I am using LabView 2013 SP1, Real Time 13.0.1, CompactRio 13.1 Feb-2014, scan mode. The cRio is doing data logging and is running without PC connected. The TDMS file is saved in USB. Everyday a startup Vi will automatically run when there is power. Today when I check the TDMS file , I fould out it stopped recording at Saturday noon, and cRio was in error.
What could the problem be, what tests could I run to figure out the error is? Any idea would be appreciated. I have attached the error log to this message

The problem appears to be something is wrong with the hardware. I recommend that you contact National Instruments about getting the cRIO repaired. Have a great day.

FTP Datasocket Error

I am trying to figure out FTP through datasockets. I have written a very simple vi (attached) that looks like it would work based on what I have read. I am trying to FTP from the ni recommended location of ftp://ftp.ni.com/incoming/readme.txt[text]. I continue to get an Error 1184 : Datasocket path not found, FTP login incorrect, or no FTP write permission. I then downloaded an example datasocket ftp vi and recieved the same error. Any hints? Could a firewall or something be causing this?
Thanks,

The problem is that you are trying to read out of a directory that the outside world only has write permissions on.
(which is sorta' why it's called "incoming" )

Any help?

Sorry but I have a real problem here that I am trying to solve. I have a separate C program. How do I initiliase my labwindows interface server with a function like this. Note that this function is in a separate C program (it is supposed to be running separately from labwindows interface). What am I supposed to do in my labwindows interface for this to work.
Note that my labwindows interface is called PuServer.
int PuServerInit()

char PU_ServerInet[20];
char ipstr[24];
nvramGetIpStr(ipstr);

if (PU_SockFd != 0) return 0;
if (strncmp(ipstr,"10.102.",7) == 0)
   strcpy(PU_ServerInet,"10.102.1.1\0");
else
   strcpy(PU_ServerInet,"192.168.2.77\0");
/* create socket */
if ((PU_SockFd = socket (PF_INET,SOCK_STREAM,0)) == DB_ERROR)
        printf ("failed PuServerInit\n");
        PU_SockFd=0;
        return DB_ERROR;
/* connect to server */
PU_SockAddr.sin_family = AF_INET;
PU_SockAddr.sin_port   = htons(port);
PU_SockAddr.sin_addr.s_addr = inet_addr(PU_ServerInet);
bzero (PU_SockAddr.sin_zero, sizeof(PU_SockAddr.sin_zero));

CompactRIO unusual error status LED flashing continuously

Hi,
I have a cRIO 9014 controller with an error i can't solve.
After re-installing LV 8.5 on my laptop MAX could see the controller but with the VISA and NI-RIO error. I wanted to obtain the IP address from the DHCP server (before i used the static IP address without any problems), rebooted the controller and the status LED started flashing continuously every 1 second. (unrecoverable error or corrupted flash memory card)
I rebooted the controller several times with IP reset but LED is still flashing. Also in MAX i can't see the controller anymore so reformatting controller is not possible.
Firewall is off, crossover cable is connected, IP of host is ok but no cRIO in MAX
Found a similar problem on the forum http://forums.ni.com/ni/board/message?board.id=170&message.id=238333&query.id=24781#M238333 but it didn't solve my problem unfortunately.
Thanks for your help!
Greetings from the Netherlands

Hello TrabW,
Thank you for your post on our webforum.
Can you try to start up the controller in safe mode? Is it possible to ping the controller? Please try the default IP address and the one you entered (in case the controller didn't reset the IP). Please let me know the results,

Datasocket Startup Error

We have a system consisting of four data acquisition PCs running Windows 2000 SP4 (Pentium III,
256MB Ram) which write data via datasockets to a server PC (dual Pentium III, 1.5GB Ram, Raid 5,
also runs Oracle 9i Standard) running Windows 2000 Server SP4.
The system was developed using LabVIEW 6.1 and the Database Connectivity Toolkit 1.0.1 and the
datasocket server ersion is 4.0(377)
On startup a LabVIEW program on the server PC starts the datasocket server. On three of the data
acquisition PCs the LabVIEW program that acquires the data is started, and once all three are on,
they simultaneous begin to broadcast data to the datasocket server on the server PC once a second.
The LabVIEW program on the fourth PC is then
started and also beings to broadcast data to the
datasocket server once a second.
The data, the data acquisition PC are broadcasting is bundled together using the Set Variant
Attribute function and has the following structured
Timestamp Double
Date Acquired once Per Second 1D array of singles (240 items)
50 Hz Timestamp Double
50Hz Data 2D array of singles (empty on startup)
The datasocket from each PC has a unique name (e.g. PC1 one is data1, PC2 is data2, etc.)
The problem is that it usually takes about three goes to start the system, the first two goes
resulting in datasocket errors (63) and if you move the mouse across the datasocket server icon in
the system tray it disappears.
Usually the system starts successfully on the third attempt, and the datasockets stay running for
as long as the system is running (i.e. days or weeks).
Does anyone have any ideas why these problems occur on startup.
Thanks

Ian,
I've got nearby the same problem (but in LabVIEW 7.0 under Win2000SP4).
Symthoms are followings:
DataSocket server crashed after start. I have tried differtent ways for startup - launch by DataSocket Server Control.vi or direct call of cwdss.exe.
It started, then connection established, and then cwdss.exe closed (with exception and record in Dr.Watson log)
I have absolutely same behavior as you described here " if you move the mouse across the datasocket server icon in the system tray it disappears." It means, that cwdss.exe unexpectable closed.
Interesting, that this problem not present on my development computer, but on all target machines (six computers at least) it happened. It happened not always. Sometimes (very rarely) DS Server st
arted properly.
The "best" solution which i have found is starting DataSocket as service. I wrote simple vi, with launch DS Server, then i have compiled this vi into exe, and put this exe as Windows Service. Now at least it works properly without any startup problems. Disadvantages of this - you will not see any more DS Server icon in system tray (but you can check that DS Server is started by presence cwdss.exe in TaskList.
Some documentation about this can be founded here:

Using Datasocket on RT target

I am trying to acquire an image from an ethernet camera using an RT target computer. The camera is attached to the same router as the host and target computer. The camera has to be on a different subnet than the host computer for things to work (host & target subnet 255.255.0.0, camera subnet 255.255.255.0)
I used the Example Grab.vi from the Knowledge Base article "Displaying an image from the Web" ( http://digital.ni.com/public.nsf/websearch/B92648089952CDD386256D0F00792187?OpenDocument ). The code runs fine on the host computer (displays image), but when I move it over to the Target, I get error 1181 "Protocol unrecognised by datasocket". The URL works fine in IE
Anyone have ideas on what I am doing wrong?

Hello RobDekker,
Did you have to download any type of driver to your host computer to get the images to appear? I doubt this is the problem, but it would definately mean that you would not be able to communicate correctly.
I found a knowledgebase that lists the protocols supported by datasockets on a Real-Time system. It mentions logos, file, and dsp. Since http is not one of the listed protocols, this is probably what is breaking the VI.

Problems with Datasocker Error Codes

I am using Datasocket as a means of communicating test status's between 4 systems on a network. The basics are working fine - each system publishes its status onto the LAN while subscribing to the status's of the other 3. So far so good. However I am now trying to build in some robustness into the app to ensure that each system works in a predetermined manner when things go wrong ie if one of the systems is switched off or if the LAN goes down, etc. I've tried looking at the Datasocket error clusters but am not sure what's going on - for example m/c 1 is doing DS reads and m/c 2 is doing writes and the error cluster on the reading app is being looked at:
If the datasocket Server is not running I get error 63
If the
DSS is started but no DS write app is running I get error 42
If the DS write app is now started - no error (this would be the normal scenario and all would be well)
If the DS write app is now stopped no error is flagged (!!??)
If the DSS is now stopped still get no error (!!!??)
But if I close the DSS and leave the DS write app running I get an error 63.
If I unplug the LAN cable from the writing m/c I get errors 0, 54 and 56 on the reading app (can't see any reason why different codes appear).
I don't seem to be getting consistent results. Any suggestions as to how best to handle datasocket errors would be appreciated.
Thanks,
Niel.

I too have complained about Datasocket error codes, messages, lack of ds browser, etc. NI said that they will hopefully have some inproved ds information in 6.1

Probelms Creating a New Predefined Data Item in DataSocket

I am doing a simple test using datasocket between two computers. When I use the "SampleString" predefined data item I can write my string value to the data socket server, which is on the same computer, and read it on a networked computer. When I create my own new predefined data item it doesn't work. I get an error saying that I have insufficient priveleges to read, write, or create items in the datasocket server. I have allowed anyhost to read or write to my new predefined item so I wouldn't think this would be a problem. Any ideas?
Solved!

Bonjour,
Merci de vous intéresser à mon problème.
Les 3 vi joint sont appelés cycliquement, car le programme Labview est "esclave" d'un Automate Programmable avec lequel il échange des commandes par l'intermédiaire d'un mot d'état.
La connexion DataSocket est établie par programme. La version de Labview est 7.1.
Le programme fonctionne, mais le fait de réduire la fenêtre de la face avant semble perturber la connexion DataSocket.
