Steps to achieve X400P7 communication over TCP/IP

Hi Experts.
I´m interested in information of how to set up an X400P7 scenario over TCP/IP.
Interested in all information I can get.

Hi,
The transport protocols ISDN and TCP are only used for polling channels. If a channel for incoming messages (message protocol X.400 P7 Virtual Inbound) or for incoming reports (message protocol Reports) is to be configured, the transport protocol X.400 P7 Virtual Inbound has to be used as well.
You should use TCP when you have dedicated router for direct dial to mailbox.

CANopen communication over TCP/IP

The NI Modbus Library makes it possible to implement the MODBUS protocol through COMPORT or over the TCP/IP. I would like to implement the NI CAN or the NI CANopen communication through a COMPORT (VISA connection) or secondary through TCP.
Can anyone purpose solutions to that challenging task?

There are TCP-IP<->CAN converters that also support modbus, so you can talk modbus TCP towards these.
The NI CAN does not hold any functions for the frames itself, this is all done through a call function library node, so creating the frames itself manually would be the only option I could think of.
If anyone else has additional information, please answer, have recently actually stumbled upon the same issue.

Need help with Modbus RTU over TCP communication

Hello!
I'm working with a project that involves communication between a LabView PC, a cRIO-9073 and a few Crouzet PLC's with XN05 modbus extentions. The issue I'm having is to get a stable and reliable connection between the units. The cRIO is communicating with the PLC's by Modbus RTU over TCP and I've created code that read and write to them in a sequential order to avoid possible ModBus conflicts. The LabView PC is sending a "ping" (boolean true) every second to the cRIO over UDP and the cRIO is then sending the "ping" to the PLC over Modbus/TCP. The PLC has a timer that waits for pings, if no ping has been recieved in 7 seconds the emergency brakes are applied and the system shuts down.
The main problems right now is:
* After a while I lose the connection between the LabView PC and the cRIO. "Connection with RealTime target cRIO-9073 has been lost".
- I also get either error code 56 or 66 on the TCP link.
* The second problem is that if I quickly pull a TP-cable from, let's say, a PLC and then directly plug it back in I want the TCP connection to quickly reestablish. However what happens is that the "pings" from the cRIO stops coming to the PLC for like 5-6 seconds (time to reestablish link?), which means the 7 second timer is almost full. One option would be to raise that timer value, but the drawback is that the system will take longer time to respond to an true error which could be bad.. My question is simply, does it really take 5-6 seconds to establish a TCP connection between a cRIO and a PLC? What affects the time?
I would greatly appreciate help or respons on this one. I attach a simplified version of the code I use (all variables and such has been replaced with constants).
Is this a good way to do a ModBus communication over TCP with 3 PLC's? Is there a better, safer, more reliable way? All suggestions on improvment is appreciated
Thanks!

Dear J,
Check the state machine Architecture here.
1. In your acquisition if you got error in any system you close all TCP connections that is not right your other systems are working fine.
2. You go with parallel loop connection. For each PLC you run separate code with error handlers.
3. Check the attached VI for TCP Read. Same VI you can modify and use for your ModBUS operations.
4. In you Sub VI you are passing a constant cluster. I am not able to understand what is the use of case structure inside the subVI, In you code you are passing the constant so its always same.
As you done previously made 3 loops or VIs to read the data in a main VI. First try to made one VI with one PLC, remove your all bugs and errors and copy it 3-time with different-different configurations.

Safety of MS Sharing on LAN over TCP/IP via NetBIOS and/or Direct SMB

Shalini Sampath Kumar at http://answers.microsoft.com/en-us/windows/forum/windows_7-security/ suggested I post this question over
here:
What is the safest recommended way to set up MS File and Printer Sharing on a LAN with both Windows 7 Pro and XP Pro machines? Does "Direct hosting of SMB over TCP/IP," help? What about setting a "Scope ID" (or did that go out
with Windows NT)?
Background: I've been trained to be paranoid about NetBIOS over TCP/IP. Right now I have only XP Pro machines on my peer-to-peer workgroup LAN (behind a NAT router and with Simple File Sharing turned off), on which File and Printer Sharing has been
unbound from TCP/IP and bound to NetBEUI instead, so I feel fairly safe. Port scanning by ShieldsUp doesn't see any ports through the router, open or closed -- in other words, it appears to be "stealthed," for what that's worth. With
NetBIOS disabled on all computers inside the LAN, however, can I perform a valid test of what will happen when File and Printer Sharing is re-bound to TCP/IP?
My New Problem: I'm planning to add Window 7 Pro machines, for which NetBEUI isn't an option, and then to transition entirely to Win7 before XP goes off extended support in April. I will still use a peer-to-peer architecture with password-protected
sharing turned on (no HomeGroup). It appears that I can still get rid of NetBIOS (and WINS) in favor of "Direct hosting of SMB over TCP/IP," which sounds safer. Apparently then only port 445 will be vulnerable instead of ports 137-139.
In any case I want to do everything I can to protect my file-sharing port(s) from the Internet (e.g., from anyone who might break into my LAN either by making a wireless connection or by hacking the router itself). Can anybody give a clear set of steps
to change sharing from NetBIOS (which I would like to disable entirely) to direct hosting of SMB and to verify that I'm protected as well as possible?
I will have to completely revamp the network-file-sharing configuration of my XP machines as soon as the first Win7 machine goes on line (and possibly tweak the configuration of Win7 as well), perhaps as early as this week. I want to do this in the way that
maximizes security to the extent possible. Thanks in advance more details and guidance on this topic! -- JCW2
P.S. -- These computers are all laptops and will be used away from my home LAN -- another reason for paranoia about File and Printer Sharing. I realize that Windows 7 provides an easy way to disable F&PS by selecting any new network location as
"public," but XP does not (as far as I know). Fixing that will take more effort and be harder to remember... -- JCW2

Removing the NetBIOS transport has several advantages compared to NetBIOS over TCP, you can find detailed infromation in the following KB

Hi again -- I think I'm slowly catching up with you. Following from my previous message...
Somebody on another forum mentioned creating "Hosts" files on each computer to substitute for the DNS server that I don't have on my workgroup. This is intriguing if I can figure out how to set it up. (I've heard it said that taking control of
your "Hosts" file is a good safety precaution anyhow, since it is a frequent target of hackers trying to divert legitimate Web requests to their own malicious sites.) Does anybody have tips and/or references that would help me accomplish the name resolution
there?
Finally, what functionality do I really lose by going the Direct-Hosting-of-SMB-with-Hosts-file (or drive mapping) route as opposed to using NetBIOS over TCP/IP? Granted, any new machine added to the network would also have to be added to all the "Hosts"
files (or mapped to a new drive letter) on each machine; but given that I already have to add it to the MAC filter and assign it a DHCP reservation in my router, this isn't a heavy burden for something that doesn't happen often. Would everything then
work the same as if NetBIOS were providing the name resolution?
One missing piece that I see so far -- it's not obvious how this same trick would apply to printer sharing (although I'm not using that feature right now anyhow). Could this be handled seamlessly through the "Hosts" file as well?
Thanks and Best Regards to All -- JCW2

SOAP over TCP using Oracle 10g

Hi everyone
I am currently working with a client and they have recently upgraded a legacy DB from Oracle 6i to Oracle 10g and now wish to be able to provide some functionality of this legacy system as a web service to their other J2EE n-tier applications.
The Oracle 10g and J2EE applications sit securely inside a corporate network. As such it would be preferable if service calls to the 10g database could be exposed using SOAP over TCP as opposed to using HTTP to speed up performance a little bit.
This is a baby step, point-to-point, SOA solution that they wish to implement before progressing to a more managed solution (eg ESB) in the future.
As I am not an Oracle expert I would like to know if this can be done and if so is it a trivial or complicated thing to achieve?
Any help would be greatly appreciated!

Hi Hatchman,
As Eric described, Oracle does not support SOAP over TCP yet. If your goal is to improve the performance, I don't think you'll gain substantial performance improvement by bypassing HTTP layer. Although it depends upon the nature of the service implementations, typically the bottleneck lies in xml processing not in the transport layer.

Process Failure when communicating over MODBUS using LabVIEW 2011 and DSC

I'm currently trying to read from a PLC's holding registers using MODBUS/TCP. I've confirmed that the PLC is updating the values and responding to MODBUS communication correctly using a third party program called Modbus Poll. However, when I try to poll the PLC using LabVIEW's shared variable engine, I am unable to read any values from the same addresses that I'm viewing with Modbus Poll.
My setup simply consists of a PC connected directly to the PLC over Ethernet, with no router in between. I am using LabVIEW 2011 SP1 with the DSC module.
I opened the NI Distributed Systems Manager to view the status of all shared variables in the Modbus library that I created and I've noticed that the CommFail bit is permanently set to "true". All other variables with a "read" access mode report "Process Failure". I've tried restarting the process as well as stopping and starting the local variable engine with no success. I've also restarted my computer several times to see if any services were failing, but this does not seem to have fixed the problem.
I finally resorted to monitoring communications over the network card that I have the PLC plugged into via Ethernet using Wireshark and I've found that while Modbus Poll is communicating with the PLC, many MODBUS and TCP packets are sent and received. However, when solely using LabVIEW or the NI DSM to communicate with the PLC, there does not appear to be any communication over the network card.
Something that may be worth noting is that I was able to communicate with the PLC and read values from it with the DSM on just one occasion, when I first figured out which addresses I should be reading from. It all stopped working shortly thereafter. Prior to this, "CommFail" was not usually set to "true" with my current configuration. Thinking that it was my firewall, I have since turned my firewall off, but this seems to have had no effect on the problem either.
Any help on this matter would be appreciated.
Solved!
Go to Solution.

Just a thought but I think the register addresses used by LabVIEW are one off of the actual register #. I was using a CRIO as a modbus IO Server and had to shift the register addresses by 1 to get things to work correctly (can;t recall if it was +1 or -1). This is documented somewhere on ni.com but can;t seem to find it now. But here is another link that may help:

How to send joystick data over TCP connection

Hi all,
I am a long time Labview discussion forum user for learning, but this is my first time posting a question, I hope somebody can help me!
In the attached VI I am trying to send data from a joystick over a TCP connection. I can send data fine using the TCP examples (in fact the majority of my VI is just a copy of the example). However I am to the point where I do not know how to send all the data necessary (3 axis data, 12 buttons, and the POV data) over TCP. Strings, clusters, and arrays were never my strong suite and converting between them is a nightmare for me.
Basically I am trying to send each axis data (X,Y, and Z), button data (12 buttons), and POV data (the POV data will be calculated to adjust the position of a camera, so the immediate data is not important, I will add functions to add the change in the button movements to write a standing position for two servos [pan and tilt], for which that I will need to send over the TCP connection) over the TCP connection to control various cameras and motors. I don't know if it is posible to send that much data over a TCP connection in one write VI through a string, and also how to separate the string on the other side in order to control the client VI.
Again, the actual TCP communication I get, and can operate fine, just formatting all the data into a string (or whatever is required) so that I can unpack on the other side is the issue here.
Another question I have (not impotant to get the program running just might make it easier on me) is can a TCP server (which sends the data to the client) also recieve data back from the client on the same port ( for example sensor data and digital positions [on,off])? Or do I need to set up two TCP communication loops with the first client acting as the server on a different port than the first, which then sends the data to the original server, which also has a client TCP configuration in another loop? I hope this makes sense...
One final question.....I already have a solution to this but using labview for the entirety of this project would be nice. I use skype to stream 1080p video from a webcam to my computer so I can view live feed. Can labview do this? This would be awesome if so, I am just not sure if the communication protocols in use could support real time (or as close as possible to streaming) for 1080p video.
Thanks all in advance for your help,

Well, you cast the axis info cluster to a string, but then you cast it back to an array of DBL. Thatr's not compatible. You should probably cast it back to an "axis info" cluster of exactly the same type. Go the the other VI and right-click the cluster wire to create a constant. Now move that diagram cluster constant to the other VI and use it as type.
Your default ports don't seem to match. You seem to have client and server roles confused. In the sever you create a listener, but then you start sending packets, even though no connection is established. The connection needs to be initiated by the client.
Your client stops the loop the first time a timeout is encountered. Shouldn't that be more permanent? Also, please retain code clarity and avoid unecessary complexities. For example, replace the "not or" with a plain "or" and change the loop to "stop if true"

You can send as much as you want. The casting to/from string is the same as described above.

The primary function of a "server" is to wait for a connection and then communicate with the client once a conenction is established. An established TCP/IP connection is fully two-way and both sides can send and receive.

Modbus RTU over TCP (Simex Transmitter and Advantech Server)

Hey Guys,
somehow i am not able to get a connection over TCP IP using RTU Mode (reading values) from a transmitter which is hooked up to an advantech EKI 1542 Server. The Port is configured as an RS 485.
i am using the modbus library and i tried to adjust the MB serial read holding registers vi to accept a TCP IP Socket input instead of an INSTR. Do you have any suggestions?
Thanks a lot for the forum support!

Hi Christo and welcome to NI Forums!
Is this the ModBus library you are using? If so, I'd recomend to check out the newer, object based library available here. It has a more straightforward setup, especially for using TCP connections. You'll find an example VI for using a master, as well as a slave device, and these you'll be able to use right away without much modification. The code'll look like:
Please test your device communication using this library.

How to read data over tcp/ip using labview

Hi,
I have a network enabled force transducer (6-axis load cell). I know its IP addr. and the data format it is sending the data out (7 32-bit DWORD, One status and 6 axis force data) . I have been playing around with the simple data client.vi example program.
When I executed the program using the devices IP addr. I used to get error 63: TCP/IP connection open. Then I ran the program using localhost in IP addr field, the program executes now indefinetly at one block only. I am attaching the screenshot for ref.
Thanks.

Hello,
I'm wondering if you can create a rather simple VI that just tries to open and close a TCP connecting to your transducer. All you would need is a TCP Open and a TCP Close wired together with the proper IP address etc. Does this run? I did look to see if there was any NetFT information and I could not find anything. I feel that the problem lies in the communication protocol between your transducer. Another place to see if you can connect to it would be to try hyperterminal. You can access this in Windows XP by clicking Start»All Programs»Accessories»Communications»HypeTermina. Using this, you can try and connect to your instrument with TCP/IP outside of LabVIEW. You might also want to get in contact with the manufacturer to verify that third-party software can indeed communicate with it. There may be a specific set of instructions that need to be sent to the transducer in order to initiate the connection and then read from it. These may be in the form of serial commands that would need to be sent over TCP. What is the make and model of your transducer?

Can I render a Flash frame as a bitmap and send it over TCP/IP?

I want to draw some combination of bitmaps, flash shapes, vectors, text etc and draw them programmatically into my movie using ActionScript, and then get every "rendered" pixel of my movie (at 100% view) into an array that I send to another program over TCP/IP. Can anyone help me here?
The first part of the question is if its possible to render a frame that is a collection of Flash elements as a bitmap? I know that I can iterate through a bitmap and get every pixel using the getPixel method but I'm trying to access the final rendered frame displayed on my screen, including, as I said Flash shapes and text.
The second question is what would be the best way to send this "video frame" over TCP/IP? Would I use an XML socket connection? That is the only way I know how to send data out of Flash over TCP/IP but I don't know if it is the only way - the help page says the data needs to be formatted as XML, which seems unwieldly for this application.
I'm doing this now by using Max/MSP/Jitter to do a screen capture the size and location of my Flash movie and then send out the resulting matrix using a "jit.net.send" object (which lets you send frames of video over TCP/IP), but this is too clumsy for the installation I am building.
Any help would be greatly appreciated!
-bob

Thanks! That was exactly what I was looking for in the first half of the question. And I guess the draw() method works in AS2 as well as AS3. I will test it but from what I understand, I can use a Bitmap as kind of my bottom-level container, then create (in ActionScript) a movie clip that can contain other movie clips or drawing API commands or whatever, animate these various elements then finally draw() them into the bitmap. I see that in AS3 I can even use getPixels or getVector to capture the full "video frame" in one line of code.
Thanks rothrock, for the helpful links. My application is kind of unusual, in that I'm sending "video" data to a proprietary LED controller box for display on a low resolution LED display. I connect to the box over TCP/IP and send it "frames of video" 20 times a second. I got this to work with this other content and software (Max/MSP/Jitter) and I want to see how I could capture all the rendered pixel data in successive frames of Flash animation, format it properly, then send it over TCP/IP to this controller box. Don't really now enough about the various flavors of TCP/IP connections to figure out how to do this in Flash, and I know there are security limitations built in to Flash that have to be worked around. But my movies are small (say 96 pixels by 72 pixels) and I need to send uncompressed data directly to my controller box, so these interesting links showing how to use server-side scripts to create jpgs or pngs are probably not going to help me. I will hopefully find a higher-level programmer than myself to work this out, and I think some of the techniques here will hopefull prove to be helpful.
Thanks again for your help!

And Database server is 9.2 and higher..
Any way I can find out why this is happening??

Maybe I'm not getting the point, but when you do not use SSL on this port, why do you want to use TCPS. Wouldn't TPC be a better choice?

SSL Connection over TCP using SSLSocketFactory to remote C++ Server

Hi.
Despite my traversing through the archives, I could not find a
solution to my problem. So hopefully, that would mean i have a simple
isolated, and FIXABLE problem :-)
My web application running under Weblogic 7.01 as a servlet needs to
connect to a remote server using SSL over tcp.
The server is a C++ app using openssl libraries to serve up a
self-signed certificate.
The code fragments to do so look like this:
     SSLSocketFactory sf =
(SSLSocketFactory)SSLSocketFactory.getDefault();
     connection = sf.createSocket(host, port);
     output.write(...)
     output.flush();
Upon the flush, I get the following error:
java.io.IOException: Write Channel Closed, possible SSL handshaking or
trust failure

My guess is that its complaining about not trusting the certificate
being sent back by the server.
I typically use JSSE for this application when running within other
appservers, and
this application has no problems. But because i've run into issues
with using JSSE in WL7.01 (another topic
for another day), I'm using the default WL ssl library.
I have set weblogic.security.SSL.trustedCAKeyStore=d:\bea\weblogic700\server\lib\cacerts,
and imported my
certificate into that cacerts file. This doesn't seem to fix my
problem. Is there another truststore
that my webapp may rely on? Where within the admin console can I
figure this out?
Or am I on the wrong track here?
Also, if its any clue, elsewhere within the same application, I make
https requests to another
web app running under the same weblogic server - and that is fine - I
use the URLConnection class in those cases.
Any help is much appreciated!
Thanks
