Adapter for TCP/IP communication with XI

Hi Experts,
The provider of the external system sez he will use TCP/IP communication...
wat adapter do we have to use in XI?? pls help

TCP/IP is a connection oriented network protocol. TCP - Transmission control protocol IP - internet protocol.
TCP/IP is a 7 layers model and the top layer is a application layer where all the applications or services are supported such as file, HTTP, Webservice etc.... PI adapters are application layer services. SO PI can support all the current adapters.
>>wat adapter do we have to use in XI?? pls help
Since TCP/IP establishes connectivity between one system to another system using network protocol, PI can use that connection for communication. You can use any adapter that PI supports. please elaborate your question.

TCP/IP communication with remote host

Hey guys,I wrote a class for TCP/IP communication with remote host.I am trying to use this class in following way:Its not working.One thing I am not sure about if I can give IP address of the machine while creating a socket.Please take a look at my program and let me know where i am doing wrong.Help me!
CommunicationAgent commAgent;
commAgent= new TCPIPCommAgent();
writer = commAgent.getWriter("CASS");
/* Send GC request message to CASS */
writer.print(searchduedateRequestMsg);
/* Get reader object to read TCP IP response from CASS */
reader = commAgent.getReader("CASS");
/* Read response message */
String respMsg = reader.readLine();
if(respMsg!=null)
System.out.println("Search due date Response from CASS is:" +respMsg);
else
System.out.println("Error in reading search due date response");
and here is my class responsible for TCP/IP communication:

Hi,
Yes, you can specify ip-address as host-address.
What do you expect the class to do? Why does reader and writer both open sockets?
What happens when you run the program?

Installable for Oracle Tuxedo Mainframe Adapter for TCP (CICS)

Hi,
Could anyone please help me to find the installable for "Oracle Tuxedo Mainframe Adapter for TCP (CICS)", does this comes with the Tuxedo 10g installable or is it a separate plug-in that I need to download and install.
Regards,
Priyanka

Hi Priyanka,
The Tuxedo Mainframe Adapters are separably licensed products and not included in the Tuxedo kits. I'm not certain the mainframe adapters are yet available for 10gR3 (I'm checking on this), and for whatever reason the latest version I can find for download is the 9.1 version that can be downloaded from eDelivery.

TCP/IP communication with LabVIEW Full?

Hi,
I would like to know if the TCP/IP VIs are included with the Base or Full version of LabVIEW?
I was looking at the different versions of LV and one of the features of the Pro version is 'Network Communication'.
I have done TCP/IP communication a while ago and I am quite sure it was with the Full version. I have the Pro version now but this is for a customer.
This brings another question: Is there a trick to be sure your code is going to work on a system with LV Base if you develop on a system with LV Pro?
Thanks!

I think that was a good answer to your first question. To answer your second question, if you are creating executables to be run on a computer with LabVIEW Base there will be no problem running the executable because LabVIEW Base has the run time engine. If you are sending VIs to another computer with LabVIEW Base they will not be able to access any VIs that are not included in there package. There is no simple way to tell that these VIs are not included except through the link in the previous post. In LabVIEW 8.6 many of the help documents state what LabVIEW package installs the VI. If all of the VIs state that they are installed with LabVIEW Base you will have no problems.

TCP client communicating with UDP server

Hello,
I want to make a TCP client to communicate with an UDP server. Does anyone know a way of doing this? I am not interested in reliable data transfer. So I don't care if the datagram is lost. I want to make the UDP server accept some datagrams from the TCP client. Also, the datagram that I want to transmit is less than 65,536 octets so it is not devided to several datagrams. Therefore, only one exchange procedure occurs.
I made an UDP server using DatagramSocket and DatagramPacket classes and a TCP client using Socket class, but the TCP client informs me that the connection was refused.
Any ideas?

Let's google for IP header and the first hit is http://www.networksorcery.com/enp/protocol/ip.htm (Whoa! Classic page! I must have seen that back when googling was called altavista.)
There is a header field, a single byte, called protocol. For TCP/IP that field contains 6, for UDP/IP it contains 17.
If you send a packet with protocol=17, the receiving host's kernel will check if it has an process listening to UDP (17) at the port specified in the packet header. No such process? Then simply discard the packet. So you can't send an UDP packet to a TCP socket because the protocol field is wrong.
If you want to fake a TCP stream you could look into jpcap, which allows you to capture and send raw packets. Google for it; and pick the right jpcap, there are two, only one of which (AFAIK) can send packets. Attempting to write your own TCP implementation is highly advanced though, and not really practical.

What programming resources exist for doing direct TCP/IP communication with the FP-1600 ethernet interface?

I am no stranger to IP communications (UDP or TCP), and I am attempting to build a project controlled by a Linux system. The FieldPoint 1600 looks interesting, but I can find no programming manual describing it's use.. only a dumbed-down 'user manual' describing how to use Windoze software. Is there any hard documentation on this device, or should I look elsewhere for my solution?

Nathaniel,
The FP-1600's use a National Instruments proprietary communications protocol. At this point in time, there are no plans to release the protocol. On the other hand, the protocol for the FP-1000/1001 serial network modules is published in the FP-1000/1001 Programmers Reference Manual and can be implemented on any platform.
If you are using LabVIEW, I have recently created a driver for the serial modules, that is multi-platform, that will be included in the next version of FieldPoint Explorer, but I will also be making it available for download independantly of FieldPoint Explorer.

Aaron

VXI-1394 adapter not recognizing or communicating with my hardware

I'm using a VXI-1394 adapter on conjunction with Labview to run some hardware that we build but the 1394 is unable to communicate with the hardware. Resource Manager runs fine and I am able to load our software in labview, but there is no communications occuring. I have swapped the suspect 1394 card with a known two seperate good ones and they work well. I am fairly confident the board is bad, but I'm not sure how to desribe what is wrong on any technical level.
-Tony

Tony,
Before you send in your controller for repair, could you clarify a few things for us? When you say that Resource Manager (resman) runs successfully what do you mean? Does it find all the devices in the chassis? Or does it just complete without locking up or failing? Also, which 1394 boards have you swapped out, VXI-1394 cards or PCI-1394 interfaces?
The reason for the first set of questions is if you are able to find and recognize all the devices in your VXI chassis when running resman, then that is an indication that the board is working, and that there is some other problem with your system.
Also, have you tried changing the address of the VXI-1394 card or resetting the EPROM or anything like that? Please let us know.
Thanks,
Logan S.

Tcp/ip communication with LabVIEW

Does anyone have experience building an application with LabVIEW that
communicates over a socket? I new to LV, but it appears that the
application I have in mind is possible. Specifically, the LV
application would open a socket (port and IP known ahead of time) and
send a character to that socket. Depending on the character sent, the
application on the other end (a UNIX process) would send back a one
integer value to indicate the number of packets to expect. The LV
application would next need to parse each packet for such things as the
packet length, data length and so forth and then distribute those data
to appropriate sub-processes. The header value types are integer,
double, byte and character. The data values are all 4-
byte integers.
The sending code (on the UNIX side) was written in C. The aggregate
throughput is relatively low; no more than 2,000 bytes per second,
including packet headers.
If I can get this to work, the results would represent a significant
cost savings over competing alternatives. As a federal employee, I'm
always looking for the most cost effective solutions.
Thanks.
-Robert
Basically, I'm just looking for confirmation that this sort of thing is
possible with LV. And, I'd like to get a better idea of how hard it
would be to do.

Hi everyone,i am currently trying to communicate with two computers at the moment using TCP/IP.I have done a simple server and client VI but the server doesnt seem to be writing the string im trying to send and it also gives an error message
Error 1 occurred at TCP Write in Server.vi
Possible reason(s):
LabVIEW: An input parameter is invalid. For example if the input is a path, the path might contain a character not allowed by the OS such as ? or @.
Please find attached the simple server and client VIs i have done.can you help me?
Thanks

Using XSLT "adapter" for invoking a WS with SOAP-ENC array type param.

Hello,
I had to write a BPEL process that calls inside it a web service which has as an input an array parameter and as an output, also an array. I already know that BPEL has limitations regarding using the SOAP-ENC Array type. I tried to rewrite the web service in order to use a literal encoding of the array parameters (using "maxOccurs" attribute), but unfortunately, the OC4J container 9.0.4 that I have to use doesn't allow this. It only allows the SOAP-ENC types for array types.
I started to write, inside the BPEL process, some "adapters" XSLT transformations before and after the invoking of the web service that uses SOAP-ENC array. The XSLT transformation before the web service invoking will translate the input array parameter defined with no SOAP encoding types (based on "maxOccurs" attribute) into a SOAP-ENC type, as it is expected by the web service. The XSLT transformation after the web service invoking will translate the returned array SOAP-ENC type into a data type defined with no SOAP encoding types (based on "maxOccurs" attribute).
The approach is pretty hairy, from the XSLT point of view and it introduces a supplementary delay due to the XSLT processing needed, but it works. The only think is that when I build the service, I obtain the following error message:
[bpelc] [Error] GCDBWebservice?WSDL:30:42: src-resolve.4.2: Error resolving component 'SOAP-ENC:Array'. It was detected that 'SOAP-ENC:Array' is in namespace 'http://schemas.xmlsoap.org/soap/encoding/', but components from this namespace are not referenceable from schema ...
But in spite of this, the process is built and deployed successfully and I was able to run it from the BPEL console.
Do you think that this approach could hide some other future problems that I can't see in this moment?
Thanks,
Marinel

TCP/IP communication with Matlab

Since LabVIEW unwisely depends on Microsoft only constructs to communicate with Matlab, has anybody succeeded in piping commands/data from a LabVIEW session running on a Mac / Linux to a Matlab session running on the same machine ? Use of MathScript is not an option since MathScript does not have all the toolboxes and more critically, does not offer a programmatic way of saving plots (the print command).

Yes, Microsoft has provided COM tools for the MAC OS. This article provides a brief overview.
Also, LabVIEW has a number of tools for configuring and programmtically printing and saving plots. I do not believe it appropriate to discuss notions of platform superiority. I simply would like you and future forum readers to be aware of the tools available in LabVIEW for plotting tasks:
Customizing Graphs and Charts

In addition, there are a number of image tools available:

Inqmy resource adapter for SAP with Bea Weblogic Server

          Hi everybody,
          Anybody have tried to use INQMY resource adapter for SAP with Bea weblogic server
          It works well with INQMY server, but with BEA I'm getting a lot of problems creating
          the connections.
          Thanks in advance.
          Xavi.


All,
          Here are the steps we (used for internal testing) had to perform to get
          IN-Q-MY adapter for SAP to work with WebLogic:
          The wli.adapter.inqmy.sapr3.spi package contains extensions to the
          In-Q-My J2EE Connector Architecture classes to overcome some limitations
          in the base implementation classes. To get around these issues, we had
          to extend their R3ManagedConnectionFactory, R3ConnectionManager, and
          R3ConnectionFactory classes.
          * The javax.resource.spi.ManagedConnectionFactory implementation
          does not over-ride the equals and hashCode methods correctly. This
          causes problems with WLS 6.1.
          * There is a bug in their javax.resource.spi.ConnectionManager
          implementation for non-managed uses of the adapter. Consequently, their
          adapter cannot be used in a non-managed scenario.
          * The javax.resource.cci.ConnectionFactory class does not support
          the getConnection() method that does not take any arguments (it throws a
          null pointer exception).
          I am attaching the classes discussed above.
          Cheers,
          Chris

How to read bytes at port in TCP/IP communication

Hiii
I am having 1 doubt in visa we knows bytes at port by using the property node...
but for TCP/IP how should i get bytes at port .... i want to read how many bytes are available in that port.....
can any 1 suggest answer......

Would you please explain why you need this?
I always use TCP Read instead of VISA Read for TCP/IP communications. If you send a package, you can first send the length of the package and then the package itself. If you read you read first 2 or 4 bytes, where the length of following package is, and than the whole package.
It works fine.

Some problems in TCP/IP communication between PC&DSP

I have programmed a VI for TCP/IP
communication between PC (Client) and DSP (Server), which could be downloaded
at below link. It just achieves some basic features, like send commands to DSP
to set some registers, and receive data or status from DSP. Additionally I programmed
a Sever vi in labview to test the client. You know the real Server is in the
DSP programmed using C language.
My problems are:
1.
I don’t know how to add some “stop”
in the two VIs to get out of the loops, I tried but it didn’t work well.
2.
I’m not clear to add some error
handles, you know when I stop the vi by pushing the round red button to stop the
vi, it turns out some error dialog about TCP/IP.
3.
It is about the TCP/IP. when
the server writes data to connection ID, if the client doesn’t read them, then
where the data goes?

可以通过添加布尔控件来停止循环，同时可以通过变量的方式来同时跳出多个循环。
你的程序肯定存在什么问题，需要的是调试。

Weblogic server adapter for eclipse 3.5 ?

I am trying to get a hold of Weblogic server adapter for eclipse 3.5 with WL 10 and java 1.5
I tried to download oracle server adapter for WL for eclipse 3.5 and it asks for java 1.6 to be present.
Where can I get a hold of WL server adapter for eclipse ?
I can go back to previous versions of eclipse if necessary but I have to have WL 10 server adapter working with Java 1.5.
I would appreciate any help any kindly soul can provide. I am tearing my hair out trying to setup integrated development
thanks

Ethernet communication with NI9149

Hi everyone,
I would like to create a rugged system by interconnecting several units by means of Ethernet for a measurement and control application. My question is if I can connect NI9149 chassis over the ethernet directly for control and communication with the modules attached to the chasis and application or is required an additional ethernet controller for each unit. The application is created in Measurement Studio. The system diagram is presented in attached file. Thanks.

The 9149 gives you direct access to I/O using a technology called shared variables, which should be accessible from measurement studio. Shared variables are a peer-to-peer protocol meaning you just need to connect the 9149 to your network and you should be able to get data.
However, shared variables are lossy and have a maximum rate -- I've seen something on the order of about 50-100 Hz update rates mentioned in various locations, although performance will be application and network specific. If you need faster performance you will have to use a FIFO (allowing you to stream data) and you will have to program the FPGA using the LabVIEW FPGA module. I believe you should be able to interface with the FPGA but it will require using the LabVIEW FPGA C interface and you must be able to call the dll from measurement studio. There may be an easier mechanism I am unaware of.
You may also consider ethercat for your application which does require a separate real-time host but is also a faster protocol. A good comparison of options is here: http://www.ni.com/white-paper/14151/en/
