Error 200428 in linux example code

Hi All;
I'm trying to use the mx daq-base on a redhat 9.0 system. I have a 6031E installed(pci). I've installed the hardware, then the software and compiled the example code. When I try to run the writeDigPort example I get;
Device indentifier is invalid.
DAQmxBase Error: -200428
lsdaq reports:
NI 603E: "Dev2" (PXIO::16::0)
Nay ideas?
Pat

After further looking into the problem I'm getting an error -200220
here is the suspect code
char chan[] = "dev1/port0:1";
error1= DAQmxBaseCreateDOChan(taskHandle,chan,"",DAQmx_Val_ChanForAllLines);
DAQmxBaseGetExtendedErrorInfo (errBuff, 2048);
printf("\nDAQmxBaseCreateDOChan returned %d %s",error1,errBuff);
This gives the following output
DAQmxBaseCreateTask returned 0
DAQmxBaseCreateDOChan returned -200220 Device identifier is invalid.
Data to write: 0x55
DAQmxBaseGetExtendedErrorInfo returned -200428 Value passed to the Task/Channels In control is invalid.
Anyone have any idea?

Error when using example code

Hi all,
im trying to create a program for communication over a LAN network with a spectrum analyser.
when i use a standard example code i get errors like this one:
[Linker error] undefined reference to `viOpenDefaultRM@4'
did i made a fault in linking?

DAV C++ uses a GCC based compiler. The VISA DLL is compiled with MSVC. This will cause a problem with the calling convertions used and expected.
Basiclly the visa DLL uses 'viOpenDefaultRM' but the GCC expects viOpenDefaultRM@4, and thus can't find it in the DLL. You can solve this manually.
The basic steps are:
1. Generate a .def file from the DLL for example with pexports.
2. correct the .def file so all the functions have the correct decorations as expected by GCC.
3. Create a new import library,
For more infomation see this post about the same issue with NI-DAQmx
An other option would be to use the Visual Studio 2005 express editions?
And in some configuration you will need to buy a license to use NI-VISA: http://www.ni.com/visa/license.htm
Hope this helps

Do I have to use an external clock with a cDAQ-9188 and NI 9401 to read a linear encoder? I'm seeing error message that implies that but the example code doesn't show it.

We can set up a task that works on demand but when we go to continuous sampleing we see Error -200303, which claims an external sample clock source must be specified for this application. However, some of the NI linear encoder example code doesn't show that (uses the cDAQ 80 Mhz clock) and the documentation didn't mention that.

It's mentioned in the 918x user manual:
Unlike analog input, analog output, digital input, and digital output, the cDAQ chassis counters do not have the ability to divide down a timebase to produce an internal counter sample clock. For sample clocked operations, an external signal must be provided to supply a clock source. The source can be any of the following signals:
AI Sample Clock
AI Start Trigger
AI Reference Trigger
AO Sample Clock
DI Sample Clock
DI Start Trigger
DO Sample Clock
CTR n Internal Output
Freq Out
PFI
Change Detection Event
Analog Comparison Event
Assuming you have at least one available counter (there are 4 on the backplane), I would suggest to configure a continuous counter output task and use its internal output as the sample clock. Specify the internal counter using an "_" for example "cDAQ1/_ctr0". The terminal to use for the sample clock source would be for example "/cDAQ1/Ctr0InternalOutput".
Which example uses the 80 MHz timebase as a sample clock? It is far too fast for a sample clock on the 9188 according to the throughput benchmarks (80 MHz * 4 byte samples = 320 MB/s). There is also no direct route between the 80 MHz timebase and the sample clock terminal for the counters--making this route would use a second counter anyway.

John Passiak

Error 1092 happened while running the executalbe file from an example code of Simulation Interface Toolkit

With Simulation Interface Toolkit 3.0.1 and LabVIEW 8.0, I built the example code Sine Wave.vi to be an executable file. I made no modification to the code except setting Real-Time Target to be localhost in SIT Connection Manager. Everything was OK during the building process. But when I run it, error 1092 was reported. Here is the error message.

To my knowledge, building an EXE out of a SIT host VI is not supported. The SIT host VI utilizes functionality in LabVIEW that is not exposed in the LabVIEW Runtime Engine (i.e., with built EXEs and DLLs).

Error while executing BBP_UPDATE_PORG Tr Code with ADD Option

Hi All,
I changed the Back end Vendor Master Data - Purchasing View (Example Accounting Number) and run the BBPUPDVD Tr code in SRM. The Business Partner (Vendor) data is updated correctly in SRM System from Back End System.
We have set of purchasing organisations like one local (SRM) Purchasing Organisation and respective Back end Purchasing Organisation (account number). When ever I run BBPUPDVD, the SRM system updates the backend vendor master data with back end purchasing organisation into SRM Standard tables. Then I am running BBP_UPDATE_PORG Tr code to have updated data into SRM Local Purchasing Organisation. I am receiving error message.
Example Scenario:
step 1: Present values in Vendor Master Vendor Number 100250, Purchaing Organisation : 1010 A/c Number: 100250-1010
and I changed the account number as 10025o-test for vendor 100250 and pur organisation 1010.
step 2: I run the BBPUPDVD in SRM System.
Step 3: I checked the values in BBPMAININT - vendor data (for backend vendor number 100250 and backend pur organisation - 1010). The SRM system replicates the values correct.
Step 4: I executed BBP_UPDATE_PORG and replaced the local (SRM) business partner (for local vendor number - 100250 and local purchasing organisation) - REPLACE Option. Then SRM replaces the SRM Business Partner (local) Data with Back end Vendor Master Data and also Back End vendor master data is deleted in SRM System. Now I have updated business partner details in SRM System as SRM Local an no SRM Back End Vendor Master Data in SRM System. This step is working fine.
Step 5: One more time I am executing BBP_UPDATE_PORG Tr code with Add option to have SRM Back End Details (in SRM System) from SRM Local Details (SRM System). Then the system is error message in SM13 Tr code.
Kind Note: There is no SRM Back End Vendor details in SRM System which I want to have with the help of executing BBP_UPDATE_PORG Tr code with Add option.
For analysis I went to ST22 (dump Analysis), the SRM gave an error message like:
Runtime Error          DYNPRO_SEND_IN_BACKGROUND

U530 Touch - Audio DRIVER ERROR - This device cannot start (Code 10) - Windows 7

U530 - High definition audio device - ERROR - This device cannot start (Code 10) Windows 7, please see the picture
Picture link (hosted on photobucket.com)
I got all drivers up to date including the BIOS, everything is working fine (the sound works, microphone works...) but this error is kind of annoying to my eyes so if anyone know how to fix it please help.
I tried to uninstall this and let windows update install it again => not worked, same problem.
I tried to re-install the Realtek driver (uninstall - restart machine - install - restart machine) => same problem
And another probelm which has not been solved yet is the Bluetooth icon keep blinking on battery mode (windows 7), you can see more in this thread

What kind of reinmstall did you perform? If you used the recovery media, then this will be pretty simple. Boot to the recovewry media again and this time select the Reinstall drivers and applications option. Find the audio driver on the list of available drivers, put a tick in the box to its left and then click on the install button in the lower right hand corner of the window. The driver will be installed. Your list will be different than the following one, but this is only an example.

Has anyone got the Comsoft Profinet example code working??

Hello!
I have a cRIO Profinet card and I'm attempting to get the example code working.
I have followed the instructions in GettingStarted_cRIO_PN_IO_Device.pdf
I have created an empty project with just the 9023 and 9113 present, and copied the 3 items from the example project cRIO PN IO-Device (LV 2012) as per the documentation.
When I try to compile I get the error shown attached. I cannot view the error as the VI is password protected.
In 5 years of working with cRIO using many different c-series modules from NI and 3rd parties I have never come across a password protected example Vi - this is very disappointing! I don't see how it will be possible to use the card without being able to access this VI, and clearly it is impossible to use it without this VI as they are unwilling to share its functionality.
Has anyone got this working on anything other than a 9104 (which the example uses?) Does anyone know the password? Is it possible to use the card without using this example code?
I will be communicating with a Siemens PLC (acquiring a load of U16s and logging on the cRIO at 20ms intervals).
Many thanks for any input, or any experiences of using this card.

Problem when using IRoomInfoReader/IRopomUsers in SDN example code

Hi I am working on EP 6.0 SP2 P31, KMC 6.0 SP2 P31 and making Room development with NW Developer Studio. From https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/kmc/knowledge management and collaboration developers guide.html I got the room extension example in com.sap.netweaver.kmc.roomextension.zip. I just add a ON_AFTER_CREATE_ROOM and code for handling this event before adding
IRoomInfoReader roomInfo = (IRoomInfoReader)context.getValue(RoomExtensionParameter.ROOM_INFO);
or
IRoomUsers roomUsers = (IRoomUsers)context.getValue(RoomExtensionParameter.ROOM_INFO);
(in order to retrieve the newly created rooms owner's id)
The example code is working, the extensions are visible, they can be added to our room template and room can be created successfully with this template.
After adding one of these two commands program stops just before this command line and there is no error message recorded in the log file.
Does this KMC release version support using these two interfaces? Thanks for help.
Best regards.
Wang

Hi Wang,
as a lucky guy working on SP2, you have all logs at hand - did you check both \usr\sap\<id>\j2ee\j2ee_00\cluster\server\managers\console_logs\...error.log as well as \usr\sap\<id>\j2ee\j2ee_00\cluster\server\managers\log\portal\logs\knowledgemanagement.x.log ?!
Did you try to log extensively? try/catch every Exception?
Both interfaces do exist on SP2 P31.
Did you check which class context.getValue(RoomExtensionParameter.ROOM_INFO) in fact produces?! (If not null, ask for .getClass().getName().)
Hope it helps

Simple example code to connect to SQL server 2002

Hi,
I found a good website a while back which showed step by step how to connect to a sql server DB using JDBC, a re-install of windows means I cant find it again. I have searched the web, but to no avail. Basically I need to find a step by step guide to using java to access data within MS SQL server 2000.

I am using Labview 8.2 with an AI Input card 9215 on CDaq 9172. The application uses a static task to read the voltage(displacement).
The app works fine, except when the app is closed(using the x in the top RH corner), then restarted I get the error -200428 at DAQmx Start Task.Vi(Value passed to the task/Channel is invalid). The only fix is to restart the PC.
I have checked that the Stop Task VI is called when the app closes. I have tried resetting the Daq device using Max but it makes no difference.
I believe there is some problem in my code closing the task properly, hence the need to restart the PC to release task resources.
Any suggestions ?

Enclosed a simple Vi that demonstrates the installed app. I have used a simulated CDaq device (identical to the customer cDaq)on my development PC and the simple VI works fine(both built as an exe and just running the VI on the development PC). The static task is identical to the task on the production app that is giving problems

However on the customer PC it throws the error -200428 even after a restart of the PC
Any ideas would be appreachiated

How to resolve error -200428 ?? New User

I am a new user of LabView which is supporting a 1331 Instron. I am attempting to get data from the Instron into a LabView program left by another sutdent. When I attempt to run the software, it detects the connection to the Instron but when I try to log the data I get the following error,
"The following error occurred during the application:
Code: -200428
SourceL Property Node DAQmxTiming (arg 1) in DAQmx
Timing (Sample Clock). vi:1 --> Instron system top level amy modified14.vi <append>
<B> Task Name: <\B>MyVoltageTask"
can anyone help, I believe it might have to do with failure to update the software etc. ...

Hey kpatil,
What version of LabVIEW are you working with. I am unfamiliar with this '1331 Instron'. Is this device a PCI based data acquisition card? The error message refers to a Task by the name of "MyVoltageTask." How did you come across this code. Is this code that was something developed on that machine and you are now just picking it up again. Or is this legacy code that was developed once upon a time and you happen to be using it on your current machine? The reason why I ask is because if this code is referring to specific tasks or devices and they are not in the same location, you may have some troubles. Also, this error occurred in one of the parameters of the DAQmx Timing Property Node, that would be a good place to start to figure out what is causing the error.
Hope this helps.

Indexed Property Example Code

Is there an example out there for a Java Newby - I am trying to save data in an array - that is using the indexed property in a SessionBean.
I have then added the indexed property and bound the value to it:
* Indexed getter for property rule.
* @param index Index of the property.
* @return Value of the property at <CODE>index</CODE>.
public Long getRule(int index) {
return this.rule[index];
* Indexed setter for property rule.
* @param index Index of the property.
* @param rule New value of the property at <CODE>index</CODE>.
public void setRule(int index, Long rule) {
this.rule[index] = rule;
public String button1_action() {
setValue("#{AdminBean.rule[1]}", selector.getValue());
I am getting the followong error:
Exception Details: org.apache.jasper.JasperException
Error getting property 'rule' from bean of type magicwheel.AdminBean
Possible Source of Error:
Class Name: org.apache.jasper.servlet.JspServletWrapper
File Name: JspServletWrapper.java
Method Name: service
Line Number: 384
Source not available. Information regarding the location of the exception can be identified using the exception stack trace below.
Can anyone help, possibly with some example code?
Thanks,
Nils

public String button1_action() {
setValue("#{AdminBean.rule[1]}",
selector.getValue());
How about
getAdminBean().setRule(1, selector.getValue());Assuming that selector.getValue() returns a Long and that AdminBean is either an Application, Session, or Request Bean.
Best regards
Antonio.
