How to read CAN interface through nisyscfg.lvlib

I need to read the CAN interface assigned to my NI-USB 8473 CAN-to-USB controller within NI's System Configuration (MAX).
The purpose is to programmatically identify the NI-USB hardware device attached to the PC, read the CAN interface assigned to it, and use that in LabVIEW instead of manually checking NI MAX after the controller is disconnected and reconnected or using it on a different PC etc.
Using LabVIEW's VI's found through
Measurement I/O - System Configuration I
Initialize, Get Experts, Find Hardware and get:
Expert = nisyscfg
VendorName=National Instruments
ProdName=USB-8473 (High-Speed CAN)
IsNI=true
IsPresent=1
Is there a property for the CAN Interface? If so, where is it found?
Is there a different way to accomplish the same thing?
Thanks, Scott.Pierskalla

This was the best I could do.

How to read Sender Interface name in Adapter module
but i am facing same error what they faced.
Please guide me to how to get sender interface name in adapter module.
Thanks

Hi Ganesh
Write a module in the sender adapter and use this piece of code
Message mes = null;
mes = (Message) inputModuleData.getPrincipalData();
String SI = mes.getAction().getName();
Also you can read the same by creating a UDF in message mapping
Following is the code
InputHeader inputHeader = container.getInputHeader();
String SI = inputHeader.getInterface() ;

Read CAN Interface of USB-8473 by programmation

Hello,
I'm looking for an example to obtain the CAN interface name of my card usb-8473. I've developped an application for colleagues and I don't know the CAN interface name they use (CAN0, CAN1, ...). It will be great if I could read this name in my application, to correctly set the object name of the CAN communication I'm configuring and opening.
As joined, an example I've started but I cannot finish.
Data location in MAX:
I'm working with:
LabVIEW 2012 SP1 (12.0.1f3), 32 bits
MAX 5.4.0f0
NI-CAN 2.7.4

How to read Sender Interface name in Adapter module

I have a need to read the Sender Interface name in an adapter module that will be attached to a Sender SOAP channel. Any ideas on how this can be done.
I am familiar with the following code construct from the docs
Hashtable mp = (Hashtable)inputModuleData.getSupplementalData("module.parameters");
fileName = (String) mp.get("FileName");
What is the key name (in the hashtable) for Sender Interface name ? The docs seem to be silent on this
I dug around some and found references to "mp.context" and "message.interface". I guess I could just test this out but I dont have deploy access and I dont want to keep asking the BASIS group to deploy the module while I play around with different combinations...
So would the following work
Hashtable mp = (Hashtable)inputModuleData.getSupplementalData("mp.context");
interfaceName = (String) mp.get("message.interface");
Thank you
Anil

Hi Anil,
I am not sure of how to get the Sender interface name. I even tried the code that you suggested above. It gave me a null pointer exception.
I think instead of Sender Interface name you can decide upon the Sender System/Service.
To get the Sender System Name:
Object obj = null;
Message msg = null;
obj = ModuleData.getPrincipalData();
msg = (Message) obj;
String SenderSystem = msg.getFromService();
Here based on the sender system you can do your partner specific processing in Proxy. Instead of Sender Interface Name.
Hope this helps

How to read mq message through jms

Hi
can anyone tell me how we can read an mq message through jms transport or by using jms adapter.
Thanks in advance.

A JMS program will be written typically to lookup administered objects ( namely connection factory and destination) from a jndi tree and use these to connect to the jms provider and read/write message to the destination. So administrators of the JMS provider usually create these objects and bind it to a jndi , which then can be used by the jms applications by doing a lookup from the jndi tree.
Websphere MQ is a messaging provider which provides a native MQ API in many languages including Java for applications to talk to it. This is a IBM proprietary API and is not same as JMS. Later when JMS became more interoperable and the standard for java based messaging applications, IBM introduces the MQ JMS API which is a wrapper around the native MQ API, so that now java clients can talk to MQ using the JMS API. Since jms applications need to lookup the administered objects, IBM came up with the utility called JMSAdmin which allows MQJMS administers to create and bind JMS administered objects. The utility is flexible that it allows the objects to be binded to different type of JNDI trees - file based, ldap based etc. But the most widely used and robust one is the file based.
So as part of configuration the first thing is to create the queue and queue manager objects by the MQ Administrator.
A MQ JMS administrator will then create the JMS wrapper objects using the JMSAdmin utility and bind it to the file based jndi tree ( a file called .bindings)
Now we need the application running in weblogic server ( the JMS Adapter ) to lookup these objects from the file based jndi tree. So for this we create a foreign jms server. A foreign jms server allows to create local jndi links (in weblogic's server jndi tree) for objects in a remote jndi provider (the .bindings file).
Finally the application will look up the local jndi name from the local jndi which will automatically resolve to the remote provider and use it.
The steps in the IBM developer work link folliows this sequence.
Hope this helps.

How to read a role through a position?

In a program I need to find the function and organizational unit to a position which he belongs, with the FM "RH_STRUC_GET" I find the organizational unit with the way of evaluation "Wegid = A003" but when I try to find the function "Wegid = B007" does not work, let me know if there is any FM allows me to search function through the position.
Thanks in advance.
Raymond.

HRP1001 I check the table, this table has a field called "SCLAS" this field when it contains "C" is a reference to the function, when I check this entry in the table has "RSIGN = B" and "relative" = 007 "But when I run the FM" RH_STRUC_GET "with" WEGID = B007 "throw me a message saying Structure 01 S 50037829 B007: No user responsible
Is there another way to find the function through the position?

How can i extract data strings (temp. press. rel.hum etc) using a Virtual interface through an RS-232 connection?

How can i extract data strings (temperature, pressure, relative humidity etc) using a Virtual interface through an RS-232 connection?

Try this. It is in LV 8.5.
Note the double % in the format string. This is so the % in the input string is treated as a percent rather than a code.
You may also have to work with the line feed characters in case they are different in the string coming in compared to how the string shows up in the web browser.

Labview misses a read when using Ni USB 8473 can interface

I was wondering if anybody here has had experience with this problem... I already talked to a Labview tech but i have not received an answer yet...
This is my problem..
I have a program that when a button is pressed, it initializes a can interface to CAN0 for example, then it writes... then it waits about 100mills and then it reads... My computer is connected to a simulator through the USB 8473 interface (I have the problem when I connect it to the hardware I am going to use), and everytime I write, this simulator sends a response... The problem is that sometimes I don't see a response... I have made sure that the simulator responds so I know it is responding... I have changed the waiting time before the read from 1 mills to 100 mills to 1 second, and still with the same result...
The way I have fixed this problem is by reading multiple times (3 times)... so every time I send a request, i wait 100 mills... then I read once, wait 25 mills, then read again, wait, then read again....
So, I wanted to know if anybody here has had to do this in order to get around this problem...???
The reason why I was asking this is because I also have another application that has to monitor my hardware by sending requests every 100 milliseconds... so I have two loops, once that writes requests every 100 mills... and another that reads the responses every 20 mills... but sometimes it looks like eventhough i read this many times, I still miss some frames, which are caught later but still not good enough...
I have posted a different thread about the above problem...
If you have questions just ask please...
Thanks

Yes, by Labview tech i meant NI Support... sorry about that...
I am still waiting for them on this subject...
I'll attach a simplified version of my code (the only difference between this code and the original is that i parse all the data that i get...)
I am attaching these if a couple replys...
Run the receive and respond (simulator) then run the CAN_PROBLEM vi... click on the OK button to write then read... you can tell it missed the message when the Frames to Read field is 0...
how are you sure that you device is sending a response?
Very sure... 100%... the original simulator lets me know when it sends the response...
Can you run bus monitor on another port, ie another USB-CAN device?
I did that, and the other USB-CAN gets it... the program I am running on the other computer is called CANyliser... I think that program waits until there is something in the queue (which I am not doing with mine)... I am just reading after I have wrote teh message (reading after about 100 mills I wrote)... So I am assuming that's plenty of time... i have increased this waiting time to 1 sec and still get the same behaviour...
