Basic TCP data communication

Hello, I am trying to build a VI that will run forever and constantly listen to a port and recieve integers and display them. i would like to make it so that a person on a different computer without labview can telnet to my PC at the port and send integers. I only want to listen to the numbers he sends, on reply is necessary. I'm trying to test my VI by running it and opening a puTTY window and telneting to 127.0.0.1 but it doesn't work. Im probably missing somehtign very simple here. any help would be appreciated. by the way im using labview 8.2

i looked at the example and its pretty much what i have. i listen for connections on port 2305. then i assume the program blocks there until a connection is established. then it sends the connection id to the tcp read. then the TCP read blocks until it receives somehting and when it does it outputs it to the front panel. then repeats the reading. i dont know what im missing here

VBAI Development Toolkit, Custom Plugin: How to get TCP data / connection ID configured in VBAI Communication Manager?

Hello,
I would like to create a custom plugin using the VBAI Dev. Toolkit. I'm using VBAI 2010 with LabView 2010.
In this step I would like to send a TCP message over a TCP connection defined in VBAI Communication Manager. How can I get the open Connection ID? Or do I have to open the connection in the Plugin? In this case, how to get the defined TCP data from the Communication Manager?
Thanks for your help.
Best regards,
Yellow

Yes you could. You can even create a simple VBAI inspection that uses the TCP step and then migrate it to LabVIEW to see how VBAI opens the connection and uses it in the TCP step. It may be more involved if you want to allow the user to configure all the TCP settings (IP Address/port) and have all your custom steps use the same settings (maybe save them to an INI and have all steps use the same INI to get the settings).
Hope this helps,

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?

CVI RT (Real Time) - HOST TCP/IP Communication

Hi,
I am using CVI 2012 Real Time with PXI hardware. I am using TCP/IP communication b/n RT and Host. RT is server and Host is client. In my application, after TCP connection is established between client and server, client will send a command , take for example "GET_DATA" to RT, RT has to respond to that by sending that data.
I am successful in
Establishing RT-Host TCP communication ( I am able to see that host is reading the welcome message sent by RT).
Host is sending the command "GET_DATA" to RT.
RT is receiving the "GET_DATA" command from Host.
In TCP server call back function, in TCP_DATAREADY event, i am using ServerTCPRead() to read data from Host. After reading the data, i am comparing the data with expected command and based on that i will be sending the data using ServerTCPWrite().
RT is reading the command from Host, but it is not writing the data to client. I am not sure whether I can use ServerTCPWrite() in TCP Server call back function.
I also tried using multithreaded concept, but not getting success.
Please suggest any solution for this.
Thanks,
Haari

Recommended way to secure my TCP/IP Communication

This may be basic, sorry, but I never had to worry about this.
What is the recommended way to secure my TCP/IP communication?
I will have a simple server listening on a TCP socket and servicing client requests. Unfortunately, the server must run at a site only accessible to the client via the internet. The client is a .NET (C#) application. Typically, I'd connect the 2 easily with standard sockets and be done. In this case, I must protect the information being transfered.
What would you use? SSL? I am not too familiar on how to do this on the .NET end.

A common way to secure communications over TCP is SSL, yes. If your question is "How do use SSL in my .NET client?" then perhaps you should seek a more appropriate forum.

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?

Tcp/ip communication problem

hello,
what i have is a tcp/ip communication problem. the server needs to see the connection on the client side terminate before it can reply with data. so i'm not sure the best way to
solve this. i tried to use a sequence structure to have the client open a connection and then send data across the port and then terminate the connection. the next part in the sequence would then open a connection and wait for the reply form the server. i had this in a while loop. an example vi would be very appreciated

Error 56 in TCP IP Communication

Hi All,
I am developing Test Cases to Test our Product, I am using TCP IP Communication to communicate the Hardware (Not NI Hardware) where a firmware is running inside. in the test cases i will communicate the firmware and request it to give me required information in a specified format, it will in response will give the required information. So as I have test cases, I will be opening and closing the port for each test case. till here every thing is going well, but after some test cases are executed I an getting a error 56 while i am trying to open the port.
I am using TCP Listen VI form TCP/IP Pallet; I am sure that not because of Firewall issue.
Please suggest me what could be the reason and solution for it
Thanks and Regards,
Phani.

Why are you using TCP Listen in your code? This is used when you are writing a server that will accept connections from remote devices. From your description it sounds like you need to open a connection to the remote device. Also, can you post your code or example code that shows when you get the timeout error (error 56 = timeout). Generally you get a timeout error when you are writing (rare) or reading from a connection. You can also get a timeout when opening a connection. If you are getting the timeout on a read are you reading the data correctly? That is, generally the data will be a fixed format and you will know how many bytes you need to read. The data may also be written to include the amount of data which is being sent. Or a very common method for simple devices is to use a termination character to mark the end of the data. You need to know how your data should be received and use the correct method for reading the data. If you simply specify to read 1024 bytes but the device only sends you 50 you will timeout. You would have to look at the data to see if you received the complete response.
If you are truly using TCP Listen you may be sitting there waiting for someone to talk to you but the device is nevers trying to connect. As mentioned earlier you may need to use TCP Open instead to establish the conenction with the device.

Process Order Basic Finish Date and Scheduled Finish Date

Folks,
I have a requirement from the business to be able to update the Process Order Basic Finish Date and Scheduled Finish Date independently from each other.
In other words, update the Basic Finish Date and the Scheduled Finish Date cannot change or update the Scheduled Finish Date and the Basic Finish Date cannot change.
I believe the reason for this is to be able to use the Basic Date to maintain the ATP accurately and keep the Scheduled Date to mark when the order was originally due from the shop floor to be able to measure if orders are being completed on time or late.
I have worked in tnx OPUZ and had some success with other issues with these dates but I can't seem to make them work independently from each other.
Or does anyone have any ideas how to measure proces order performance to the production schedule?
Thank you for your help,
Greg

Rajesha, thank you for your reply but it doesn't solve my problem.
Let me restate my scenario:
I start a process order and both the basic and scheduled finish dates are the same, June 1.
At some point, shop floor tells me they will be late and cannot deliver until June 15.
I need to update a date in the system so the ATP and the MRP planning runs have correct information for promising customers, I will update the Basic Finish date with June 15.
I also need to keep the original June 1 date in order to measure the shop floor performance to the production schedule to measure how early or late the order was delivered. How can I keep the original finish date or how can I measure if a process order is early or late??
Thank you for your help,
Greg

TCP\IP Communication in the XI

Hello,
We have a scenario in which we have to communicate with a 3rd party system from our ECC system using the tcp\ip protocol. We used the XI by building a BPM with a transformation step that uses a java class, in which we opened a socket connection and sent and received our messages, as described in the weblog .<a href="/people/saravanakumar.kuppusamy2/blog/2005/12/15/socket-integration-with-xi:///people/saravanakumar.kuppusamy2/blog/2005/12/15/socket-integration-with-xi
The main problem we encountered is that we have to maintain a continuous connection to the 3rd party system, and we can't find a way to make this possible using the XI (it keeps stateless beans for the transformation steps, therefore closing the connection when the class run ends).
Is there a way to maintain a continuous connection of tcp\ip from the XI? Maybe by using an adapter?
Thanks in advance,
Tal.

I used the transformation class to call a custom web service that keeps the connection open and handles all tcp/ip communication.

Need to count the number of times the Basic Finish data chages

HI Expertes,
I have a requirement I need to count number of times the Basic finish date chaged for PM work order. I went throug our forums I got some info like using a standard function module
CHANGEDOCUMENT_READ_HDRS_ONLY
CHANGEDOCUMENT_READ_HEADERS
CHANGEDOCUMENT_READ_POSITIONS
But all the above function module will not be suitable for my requirement since CHANGEDOCUMENT_READ_HDRS_ONLY it gives whole changes but my requirement is just need number of changes occurred in Basic Finish date but CHANGEDOCUMENT_READ_POSITIONS can give the filed number which has been changed but still I need change id.
So kindly suggest me wether there is any other Standard FM to get number of changes occurred in Basic Finish date?
Thanks,
Rajesh

Hi Debbie,
     To count the number of groups please try the folling steps:
1) Create a formula @reset and place this formula in the page header

2) Create another formula @evalgroup place this in the group header where you want to count the values.
    whileprintingrecords;
    numbervar i:= i+1;
3) Create another formula @display and place this in report footer.
    whileprintingrecords;
    numbervar i;
In order to display the count of details which are printing in the detail section place the eval formula in the detail section and the @display formula in the group footer.
Hope this helps!!!

Hi VM,
Input is Order Number (AUFNR).
You can find the Basic End date of Order in Table AFKO, filed is GLTRP.
For work center in Operations, you can use the Table AUFPL from AFKO.
Pass this AUFPL in AFVC and get the ARBID.
Then pass this ARBID to CRHD Table as OBJID, and get the work Center (ARBPL)
