DSC TCP IO Server
Hi,
In LabVIEW8.5 DSC Module, i used to create a TCP IO server using express VI, The thing i cant able to change the IP address even in development mode or in run time. But in case of Serial IO server i can abel to change the com ports, So i am looking forward for this...
With Regards,
vijay.
Hi carla,
Here i attached the sample VI to get more clear on this,
Run time is when i press Run button and development time means, when i double click the express VI in block diagram, a popup window will come there i can assign the IP address.
i connect an error cluster to modbus IO server, but no error is displayed.
The device we are using for ethernet and serial port is differrent, The thing is whenever we assign or change the IP address its not assigning to Modbus IO server itself, then how it can communcate with device.
To assign a IP address to Modbus IO server (Ethernet), we like to have control in front panel to type IP address.

TCP data server or better solution?
Hi all,
We upgraded our software system from 32 bit to 64 bit then LabVIEW is also upgraded from LabVIEW 2010 x86 to LabVIEW 2010 x64. However, one device of us does not have the 64 bit driver thus in order to make all the devices works seamlessly in one computer as before, I used TCP data server and client. The server and the main VI are set up on the LabVIEW x64 whereas the client, which drives one device with 32 bit driver, is running on the LabVIEW x86 process on the same computer. I used the Simple Data Server and Simple Data Client in Examples of LabVIEW.
Would you please advise me or give me some suggestions for the following questions:
1. By using this configuration, I can only transfer data in one way. If I want to transfer data in both directions, what should I do? Could you please give me some example codes?
2. I do not understand clearly the synchronization of the server and the client in this case. For example, when I change the waiting time of server and client, sometimes it freezes the program, sometimes it does not work. Could you advise me the perfect way to set the synchronization (as fast as possible).
3. Is there any possible solution that could be better than this data server/client approach for my 32 bit driver related problem as described above?
Thank you very much, I appreciate your help.
TrungCould you guys plesae give me some answers/suggestions.
I appreciate it.

Initial Deserialization on TCP*Extend Server
Hi Guys,
I have observed something on a TCP*Extend server which I can't quite explain. We've got some hairy custom serialization inside an Externalizable bean. I was under the impression that classes aren't deserialized inside the cluster unless they need to be e.g. to processed by entry processors or value extractors on indexes. However, when I put one of these objects from a TCP*Extend client into the cluster on the tcp*extend server I see some slightly odd behaviour on the server where the deserialization method is called on an empty object and the object I've just send from the client is then serialized.
Can I therefore assume there is an extra deserialization/reserialization loop on a tcp*extend server on data obtained from the client?
Kind Regards,
MaxHi Max,
Yes, currently the ProxyService must deserialize/serialize data sent from/to clients as part of a POF translation step in order to support non-Java clients. We will be extending POF serialization support "into" the cluster in the next Coherence release. Once this is in place, this extra deserialization/serialization step will not be necessary and will be removed from the ProxyService.

Edited by: Anand Gupta on Dec 4, 2009 5:10 PMDavid,
Thanks for your detailed response. I will try all that you suggested and let you know my observation at the end. To give a back ground of the application I am working on.
Background
Try to replace home grown cache (very well optimized uses custom serialization using NIO bytebuffer etc.,) my mandate is to replace the legacy cache with coherence (I love coherence product (at least 3.4) from my previous job experience). Since all kind of optimization is done in legacy application I am converting NIO byteBuffer generated by legacy serialization to byteArray and converting ByteArray into POF. Also for various other reasons, I have to send entry processor to do even get and put data from the cluster.
Raw Data Set Size
My data size is just 500MB (In Production). I put enough cache nodes so that raw data is just 50MB per node. (Since it is compute heavy with entry processor and the number of clients are going to be ~2500)
What was happening when I got the exception?
I was doing stress testing of the cache. Not sure if that put lot of garbage in some of the node hence may be the garbage collection pause triggered the re-distribution of partition set. Since the stress testing was on the way it might had cascading effect on all the nodes.
Datagram Test result.
Tx summary 4 peers:
life: 96 MB/sec, 68774 packets/sec
now: 100 MB/sec, 71378 packets/sec, packets/burst: 1029, bursts/second: 69.41594
Success rate ranges from 0.87 to 1.0
Is a success rate less than 0.98 a cause for concern?
Regarding Size (to keep the extend client always connected to the proxy)
I do size request every 5 sec. if there is not other request has gone to the cluster in the past 5 sec.
In one of the oracle presentation it was said that "If you have map listener's and no other request from a long period of time extend client has to do a periodic size request to make sure that connection to proxy is alive"
In this regard my question is "Can the same effect achieved by doing member listener on the extend client and on disconnection do the size request?"
Proxy Size guide lines
In production number of extend clients are going to be ~2500 connected all the time.
Of which 2000 clients with few map listener + entry processor gets (Each of the clients will have distinct and disjoint set of data on which they work and listener)
And the remaining ~500 clients will do all kinds of request on the entire data set.
In this circumstance is there any recommendation for Number of extend-client : Number of extend-server : Number of threads ratio?

TCP EXTEND Server SIde configuration
one of the configuration which is required for server proxy scheme is address ofteh server
I can't specify localhost as server and tcp client is going to run on two differenet servers
I have to run this tcp extend server for 3-4 server for failover support
How can I specify address ( IP ADDRESS HERE) which can changed for each server configuration without specifying this config for each server differenetly
can I replace this address besed on property or system parameter or spring injection.
<proxy-scheme>
<service-name>ExtendTcpProxyService</service-name>
<thread-count>5</thread-count>
<acceptor-config>
<tcp-acceptor>
<local-address>
*<address>IP ADDRESS OF SERVER HERE</address>*
<port>9099</port>
</local-address>
</tcp-acceptor>
</acceptor-config>
<autostart>true</autostart>
</proxy-scheme>
</caching-schemes>Why can't you use localhost? Surely this is what you want unless you are running on a machine with multiple network cards and need to bind to a particular address.
If you really want to be able to specify a different address for each machine you can do this
<proxy-scheme>
<service-name>ExtendTcpProxyService</service-name>
<thread-count>5</thread-count>
<acceptor-config>
<tcp-acceptor>
<local-address>
<address system-property="extend.address"></address>
<port>9099</port>
</local-address>
</tcp-acceptor>
</acceptor-config>
<autostart>true</autostart>
</proxy-scheme>Coherence will now use the value of the extend.address system property as the value for your address. This can be passed in on the command line like this:
java -cp coherence.jar -Dextend.address=IP_ADDRESS_HERE com.tangosol.net.DefaultCacheServerObviously your command to start the cache servers would probably have more in it than that.

Using control reference with a Sub-vi over a TCP VI Server connection
I tried to use a Call by Reference Node to run a sub-vi on a remote PC through a TCP VI Server. An output of the sub-vi is connected to an indicator in the main vi using a control reference.
The sub-vi started on the remote PC, but the information from the sub-vi was not passed to the control reference in the main vi. However, if I change the client name to the host PC, ie. running the server and client vi on the same machine, the code works as planned. I wonder if control reference is not suppose to work over a TCP VI Server connection?
Any suggestion would be very much appreciated.
Regards,
Calvin Tsang

main_vi.vi 29 KB
sub_vi.vi 20 KBThank Jean-Pierre for pointing out that Refnums are local to an application and so control reference doesn't work between different applications on separate machines.
In addition to the method shown in Jean-Pierre's example vi, I found that the use of "invoke method: GET control value" and "invoke method: SET control value" can produce similar results. See the attached files for an example. In this example, the indicator on the local vi is used to monitor the progress of the remote vi and the local control is used to stop the remote vi. So the data synchronisation between the two vi is not important here.
However, you may notice the indicator "current counter" in main1_vi.vi doesn't properly interpret the binary string from "invoke method: GET control
value", can someone shed some light on this, please?

Hi All,
I have posted TCP client- server prog. I have trouble in client code. When i'm running the server code on some port and the running the client code on the same port, then client is sending message to server(in this case integers with space like 12 22 23) , the server is receiving the message and adding the sum and sending the sum to client, but when i'm trying to read the stream from server(i.e the sum), i'm getting nothing.........
please run the code and check.......u can understand well....
please reply me as soon as possible.

How To Ask Questions The Smart Way
Eric Steven Raymond
Rick Moen
Write in clear, grammatical, correctly-spelled language
We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy at thinking and coding (often enough to bet on, anyway). Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal - in fact, hacker culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
Spell, punctuate, and capitalize correctly. Don't confuse "its" with "it's", "loose" with "lose", or "discrete" with "discreet". Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All-smalls is only slightly less annoying, as it's difficult to read. Alan Cox can get away with it, but you can't.)
More generally, if you write like a semi-literate b o o b you will very likely be ignored. So don't use instant-messaging shortcuts. Spelling "you" as "u" makes you look like a semi-literate b o o b to save two entire keystrokes. -
TCP/IP-Server generates large amounts of Handles
We used a Labview program as a TCP/IP server on an embedded pc. The
Connection was established and closed by the client. After a large number of
connections the communication is slowing down and fails finally by timeout.
We discovered, that each connection seems to generate a handle but did not
set it free after the connection is closed by the client.
We tried to close the connection by the server too, but the number of
handles is still growing till the serverprogramm is stopped.
We are using Windows 2000, Windows XP and Labview 6.01Hi...
Download a tool called TCPVIEW (its free from www.sysinternals.com)
What you will probably see are quite a few ports that are in the TIME_WAIT stage.
If you connect and disconnect too quickly, ports are put into the TIME_WAIT state, but not reverting back to the LISTENING or free'd state.
(This is just a theory at the moment). I had a similar problem some time back...
Here are some links about the problem of TIME_WAIT, but I can't think of any fixes at present...
(It may come to me while I am posting these links)
Hope this helps,

TCP/IP server module with EE container
Hello All!
I am developing an EE application that has the following features:
- web app to browse data
- a scheduled server module that sends queries through TCP/IP (with SSH) to the large number of devices. The responses of the client are saving in DB.
My questions are following.
- What kind of API/library/server to use as a TCP/IP server? (Netty, Mina or something else?)
- Which application server is better to use in this case? (I intend to use Glassfish v3.)
I'm going to use MySQL, for back-end - Spring & Hibernate, for front-end Spring MVC & JSTL.
Thanks!
AstridI don't see you needing any kind of JEE features other than the web layer, so I would consider adding Tomcat as a possibility for your webserver choice. Cheap, fast and easy to use.
Other than that nobody is going to tell you what you should or shouldn't use - that is your own job. Research my man, research. Perhaps you'll want to share your findings here to get a second opinion, but don't expect the answer to be spoon fed to you. Go dig up which possibilities you have (of course, use Google), compare their features, search for discussions about issues with the individual products and make a weighed and reasoned decision based on all that. -
Dsc module modbus server handling uint8 variables
Hello!
I have a problem with handling Modbus uint8 variables in the dsc module . Unit8 Shared variables
are available in labview but Modbus i/o server Unit8 variables are not:
http://zone.ni.com/reference/en-XX/help/371618J-01/lvmve/dsc_modbus_using/
In our controller we split some 16 bit modbus registers into two 8 bit variables to pack some more usefull data in there.
All of my shared variables are running nicely in the shared variable engine but I've no way of
easily binding them to my Modbus i/o server uint8 variables easily.
Any ideas?
I like the auto-scaling logging and binding of the DSC module shared variables
so I want to avoid some manual labview processes.
I want to view all shared variables in my front ponel at run time. I have 300+ variables so I'm trying to avoiding manual one-off hacks.
Jamesjamesy777,
The reason Unit8 variables are not available in the Modbus I/O sever is the nature of the I/O server data types compatible with the registers. If you’re writing to two registers, you can just read those two separate registers as U16s in LabVIEW. Otherwise, if you’re writing to the upper and lower half of the register, you can split the register into its 8-bit halves using the Split Number function in LabVIEW.

[Bug?] DSC - Registering for Server Events
[LV2009, Win 7 Pro]
Howdy (Ben S another one for you? )
I am trying to register for alarm events.
This works fine by using the Register for Shared Variable Events method.
Since I have a lot of SVs and a dedicated server, I thought listen to the server would be much easier to implement.
The LabVIEW Help implies that using the Request System Event Notifications.vi will do the trick:
However, I can't seem to Register for Server Events - it doesn't work.
The code seems quite simple (below) - I just want to listen to all SVs on the localhost (default).
All the Events are coming through to the DSC (viewed in MAX), however, using the Server method I don't get any notifications through the Event Structure.
Am I doing something wrong? - Or is this a bug?
Is there somewhere I need to configure stuff?
Or does it just not send me Alarm and Notification Events of Shared Variables?
What does it send me then?
I couldn't even get the Example in NI Example Finder to work (labview\examples\lvdsc\Event Structure Support).
It shows the SV Registered Event but not the Server/System Event.
Attached is a simple project I used to demonstrate this - a SV configured for a HiHi Alarm:
The work around is to list out all Shared Variables and just read that from disk and load it into the application etc...
However, it is much more desirable to subscribe to the server and get all SV Events - is this possible?
Cheers

From the help - I didn't think this was possible?
I gave it a go using the following naming
But I get the following error (I tried to connect to multiple SVE across our network and got the same error).
I can use though and it returns the local SV List, so I think I have the naming correct?

My other thought is to build a hook in to the app and invoke this across the network using VI Server, so that it can run the VI on the localhost then report back the SV List).

DSC: Custom IO Server: On Input Change
I have written a custom IO Server VI using DSC Module. Using NI DSM, I see that the server status is 'Active'.
Again using DSM, I change the value of the control that is suppose to trigger the VI to run, but it does not run.
What am I missing? I have been successful at creating several Custom Periodic Servers, but this is my first 'On Input Change'.
Note: I am not using 'shared variable value change notification' in this On Input Change VI, because Lesson 4 of DSC Training leads me to believe that mechanism is not necessary.
Anyone have examples of both types of custom servers?
Thanks
Solved!
Go to Solution.Okay, I got it to work. Got a new, very simple server code to work. Then removed original library from project, recreated IO server from scratch, added back into project, and now it is working.
Would still like to see examples of both types of custom servers to see how to handle error conditions.. Lesson four says 'make sure VI is robust enough to handle/recover from error, but doesn't give examples. -
All,
This may not really be a LabWindows/CVI question but I'm really stuck on what should be easy to
solve. The brain trust here on the forums has always been helpful so I'll try to explain.
The project:
Get LabWindows/CVI code talking to a muRata SN8200 embedded WiFi module.
The setup:
(running Labwindows/CVI 2009)
Computer 1 -- (with a wireless NiC) running simple demo TCP server program provided by muRata.
Computer 2 -- USB connection (virtual COM port) with simple program (also provided by muRata) that talks to the SN8200 embedded WiFi module. This code along with the module creates a simple TCP client.
Whats working:
I can successfuly get the Computer 2 client connected to and talking to the Computer 1 server. (using the muRata supplied code)
I can also run the LabWindows/CVI sample code from (\CVI2009\samples\tcp), server on computer 1 & client on computer 2 and they talk with no problems.
(I'm using the same IP addresses and port numbers in all cases)
Whats NOT working:
Run the CVI server program on computer 1.
I cannot get the muRata client program to connect to the CVI server.
I also tried get the CVI client program to connect to the muRata server. No luck that way either. The CVI client sample program trys connect, and this function call:
ConnectToTCPServer (&g_hconversation, portNum, tempBuf, ClientTCPCB, NULL, 5000 );
returns with a timeout error code (-11).
What I need:
Some ideas on how to get this working.
Is there something unique about the LabWindows/CVI sample client/server demo code that would make them incompatible with the muRata code?
Can you think of some ways I can debug this further? I feel like I'm kind of running blind.
What else can I look at?
For those that have read this far, thanks much and any ideas or comments will be appreciated,
KirkHumphrey,
First,
I just figured out what the problem is:
When I was trying to use the CVI sample server I was entering the wrong port number.
The reason I entered the wrong port was because the hard-coded port number in the muRata demo code was displayed in hex as 0x9069. ( I converted this to decimal and entered it into the CVI sample server code) The correct port number was 0x6990. (upper and lower bytes swapped) Arrgh!
I found the problem by using the netstat command line utility to display the connections and noted that the port being used was not 0x9069. It is really a problem with the muRata eval kit demo code.
Second,
Humphrey you are right about the CVI sample code not handling all the muRata commands for the client end of the connection that communicates with the SN8200 module. For my test I was using the muRata code for that "end".
The server end is simple and the CVI sample is adequate and is now working.
Thank you to all who took the time to browse my questions,
Kirk -
Hello all,
hope its not too irrelevant to the labview.
I have gone through "simple data client.vi" and "simple data server.vi" examples, want to replace simple data server.vi with a simple c program on a different computer.
Can someone please hint me how to form it?? using v8.5. The ultimate need is: c-program sends the required data to client(labview) whenever it is being requested.
The labview and c-program are on different PCs.
Not sure whether simple c-language instructions inport and outport(from dos.h) will do? or do I need to do some socket programming??
Thanking you.
Message Edited by Parny on 12-09-2007 08:10 PMHi,
You should be able to find a good TCP example written in C on the internet. Searching on NI's website will most likely only yield LabVIEW examples. Here is one link I found on the internet. I would search google for "tcp" and "C" to see what you might be able to find.
