Enet IP communication with 1794-AENT module

Has anyone had success with communicating with the Rockwell 1794-AENT/B ethernet modules? I have one of the Flex I/O ethernet interface modules with two 8 port analog in modules connected. I can read the 1794/AENT module information, using the ENET-I/P library, like model, version etc but nothing representing the I/O data.

Kudos! Thanks!

Adam, I am using Labview 8.6 with the EtherNet-IP library. I have a ethernet connection to the 1749-AENT/B module and that is woring and tested. Attached to the 1749-AENT/B interface is a 1749-IE8K 8 port analog input module.
I am able to read the attributes from the 1794-AENT/B module using the Ethernet-I/P library's "EthernetIP CIP Get Attribute Single VI" function in Labview. I get the name of the module, the major and minor versions, the type of module etc. What I can’t seem to figure out is how to read the I/O data from the 1794-IE8K module attached to the 1749-AENT/B. I'm trying to use the "EthernetIP Tag Read VI" function in the same library. It might be that I just don’t know what the “Tag Names” are supposed to be.I’m using an Ethernet-IP “EthernetIP Tag Read VI” function from the Labview library that is wanting several variables. The network path is the IP address of the module and I know that’s right. Also asking for a “Tag name” and number of elements. These two I’m not sure about, maybe one of your guys can help me with what the Tag name should be and how many elements there should be. Also I can select the type of data out which can be an SINT, DINT, INT, BOOL, STRING, RAW or REAL. I’m assuming INT or DINT then scale. Thanks for the help. Greg Yotz CVC

But it cannot help me.
I think that this problems related. Yesterday all works correctly.
Thank you for your help.

You are right the problem was related with antivirus.
After removal antivirus DCA Server started successfully.
Remains the question as to be without an antivirus program?
Also remains a problem in the window Alerts and Activites.
When I click on the Device Name field (for some devices) does not open Detailed Device View.
The window closes immediately after opening.

Error in communicating with IPMProcess or IpmDbEngine

Hello there,
I have a problem with IPM module. Everytime i try to access to this module it always appears the following error "Error in communicating with IPMProcess or IpmDbEngine. It may be down or not yet up. Please make sure processes are up and running". Then i go over the processes link and it shows:
IpmDbEngine
Program started - No mgt msgs received
IPMOGSServer
Program started - No mgt msgs received
IPMProcess
Administrator has shut down this server
... so i start the IPMProcess, then i go back to any of the IPM configuration links but still show me the same error.
Could you tell me how tosolve this problem??
I am working with LMS 3.1 and the IPM version is 4.1
Regards,

I have set the regional parameters as you indicated. It remains with the same problem. I revised the IPMProcess log but it did not have any changes thus i am not uploading it.
I looked over the services window and realized that Daemon manager is not started so i tried to do so but it doesn't start. Any suggestions to run that service first?? cause actually i know that if daemon manager doesn't work then any of the modules is going to respond anyway.
Regards,

Help DSCC agent not communicating with AppServer or Tomcat?!

Installing Directory Server Enterprise Edition 6.3 From Zip Distribution on system running Solaris10 11/08.
Cannot get DSCC to work with either AppServer or Tomcat.
Both AppServer & Tomcat deploy DSEE WAR file and I can look at things that I have manually registered via command line. Cacao agent is running it is just not communicating with AppServer or Tomcat so it cannot commit any actions such as starting and stopping directory instances or creating new directories instances within the web app.
Is this a bug that occurs only when doing a new install using the Zip Distribution?
The Error message I get regardless if Appserver or Tomcat is:
"Could not contact the DSCC agent on <server>. Use the command cacaoadm to check that the DSCC agent is installed and running on port 11169."
I changed to port 11169 because it had a conflict on default port 11162.
Output from cacaoadm & dsccsetup commands is follows:

I started over and installed Glassfish and everything just worked. After the fact I think the real problem was related to the server.policy file. I think this was the problem because using the default appserver 8.2 that comes with Solaris has a different path and I got this same error when tried using tomcat also. When installing glassfish it uses this default path as in the server.policy example as follows so it just worked.
Add the following lines in the {install-dir}/domains/domain1/config/server.policy file
// Permissions for Directory Service Control Center
grant codeBase "file:${com.sun.aas.instanceRoot}/applications/j2ee-modules/DSCC/-"
permission java.security.AllPermission;
Hope this helps some as I was really stuck and confused at the time and just started playing with the stuff. Growing pains. Thanks to those that replied.
Thanks!

Teststand best practices architecture for communicating with TCP instruments

Hi,
I am using Teststand 2014 and LabVIEW 2013 SP1 as the module adapter.
My Teststand sequence file includes communication with 3-5 different instruments via TCP/IP.
Such as Spectrum analyzer, generator and other RF measurement devices.
There are many steps located in subsequences that implement code to communicated with these devices whether to fetch , query or write.
What is the best architecture to implement this program ?
As I can see it there are many possibilities, such as :
1. Launching a subsequence as a new thread in the Sequence Setup. This subsequence calls a VI that dynamically register for events/queue that can be launched from any step. (in this case there is a VI running in the background that can perform Write/Read/Qurey to the instrument and he is triggered from any step using an event or dequeue element)
This option can be duplicated for any instrument or only once for all of the instrument with prioritizing the event queue.
2. Creating a communication reference in the Setup of the Main Sequence. And passing it to any step that need it. (there is also the question how to pass this reference… in Teststand globals or in LabVIEW queue).
another 2 small questions that I encountered -
Is using LabVIEW queues and notifiers in TS steps and obtaining their reference (in the LabVIEW code) by name is considered best practices ?
If I would like to run only one VI in a new thread, should I use a new subsequnce and set it as a new thread or use the Run VI Asynchronously ? what are the differences ?

I use Action Engines to hold my VISA Sessions and just write my LabVIEW VIs to use those to send commands and read data. Any returned data can be analyzed in the VI or passed on to TestStand as a step result. You just need a sequence to run at start up to initialize your Action Engines and another one to close them.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Commands to FTDI virtual COM port via NI VISA interfere with communication with FTDI chip using D2XX drivers

Hello!
I am trying to communicate with a DLP Design module DLP-USB1232H which uses an FTDI chip. My program uses the D2XX drivers. It works, but...
In another program that runs at the same time, I'm communicating with another instrument via a virtual COM port (VCP) that uses an FTDI UART. In this program, I use the VISA Serial Port functions. It works, too, but...
The first program has the capability of listing all the FTDI devices in the system prior to choosing the right one to communicate with. When the VCP is plugged in, it lists it (FT232R USB UART) along with the DLP-USB1232H and communication with the latter device works. But as soon as the second program sends a command through the VCP, the first program no longer "sees" any FTDI device. It stops working.
I have tried 2 different FTDI VCPs; one a standalone cable and the other built in to the instrument.
I’m using Windows 7 32-bit. My programs are both LabVIEW 8.5 executables.
Is VISA "taking over" the channel to the DLP-USB1232H? Does someone who understands NI's implementation of VISA have any ideas on why VISA is doing this? Or if something else is going on?
I'm also interested in workaround ideas. I've tried a "Prolific" VCP, but most drivers don't work and the one that doesn't give an error in Device Manager doesn't communicate with the instrument.
Cheers
Halden
Solved!
Go to Solution.

Halden,
It really sounds like you have a resource conflict. That occurs when two programs or parts of programs try to use the same device or port at the same time. Your Get Device Function probably tries to open a session with each port (as you increment the index). When it hits a port which is being used by the other driver, it cannot open the session and stops working? Have you examined the errors returned by each program? The VISA drivers will return an error when the port is in use. I do not know about your program or drivers, but I would expect some kind of error. Automatic error handling in LabVIEW will not catch errors from a driver if it does not translate them to LV error clusters. So do not count on automatic error handling, if you use it, to display all possible errors.

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/

Direct communication with SIEMENS PLC

I am trying to establish a direct connection with a SIEMENS S7 PLC. I donot want to use any card or profibus etc. I want to do it through the Serial Port.
I have used the IA server kit when communicating with SIEMENS S5 for which I used AS511 protocol. I would like to know if there is any such protocol for S7.
Please Help!!

Hi.
I'll try explain it.
All Simatic S5 PLc's processors (CPU90 ,CPU100) have got serial (current loop converted to RS232) physical inteface as standard.
You can program PLC's or communicate with its by AS511 protocol.
S7 Simatics processors (CPU 3xx, CPU4xx) haven't got RS232 interface as standard. RS 232 interface occurs in forms of interface module connected to the rail (slot) and doesn't serve any protocol (simple chracters exchange).
You can program PLC, observe/modify I/O, variables, etc. only by standard RS485 interface using protocols MPI or PROFIBUS (PPI/MPI for Simatic S7-2xx CPU's).
You can try exchange data between Labview and S7 PLC by serial in characters form, but it is very difficult and inconvenient (you have to w
rite own driver for Labview and program for S7).
Another solutions:
1.PROFIBUS card for PC with drivers for Labview (I don't know if they exist)
2.connection thru OPC server (PLC->PC by PROFIBUS card->OPC server->Labview by Datasocket)
I think second solution is more comfortable.

Z77A-GD65 no longer boots with 4 RAM modules

I had 4 x 8GB Cosair Vengeance LP that used to work fine, but no longer boots into Windows with 4 but only with 2 RAM modules. Any help in solving the issue would be appreciated. ( I need 32 GB as I run many virtual machines )
The 4 modules worked fine for few months until couple weeks ago, when I saw issues with booting into Windows 7. The workaround was to "warm up" by leaving the PC in BIOS for about 5 minutes and it would boot fine. Since couple days ago, it would POST but not boot into Windows or into live Linux on USB, so I started troubleshooting with bare bones first ( MB, CPU, 1 RAM, PS ) and then starting adding more and more components until I found that 1 and 2 RAM modules worked in either black or blue rail but with 4 RAM modules, it will POST, but not boot at all into either USB based live system or into Windows 7.
Memtest with 2 separate sets of modules pass with flying colors. Mixing the sets work fine too, but add 2nd set (i.e. 4 modules) and it fails to boot. I am leaning more toward believing the issue is with the MB than with the RAM since mixing them doesn't throw any memory error.
Any suggestion on how to check if it's the RAM or MB ?

If these were 2 kits mixed, ...

What voltage is the RAM running? A slight bump up in voltage might help.
As to voltage, I started with standard 1.5 and then incrementally upped it to 1.65v. At 1.6v and above, it does boot into Windows, but intermittently goes into BSOD... Works perfect with 1.5v with 2 RAM modules.
I'll save the money for next build instead of going for 32GB kit. ... guess I'll live with 16GB for now.
Thank you all for the advice.

Sir i am using datasocket read ,i am communicating with java but my problem is that bcz im using while loop to see if value has changed my labview consumes all the processors time ,sir i want a event like thing so that while loop is not in continuous loop

sir i have given lot of effort but i am not able to solve my problem either with notifiers or with occurence fn,probably i do not know how to use these synchronisation tools.

I want to pass along a couple of tips that will get you more and better response on this list.
1) There is an un-written rule that says more "stars" is better than just one star. Giving a one star rating will probably eliminate that responder from individuals that are willing to anser your question.
2) If someone gives you an answer that meets your needs, reply to that answer and say that it worked.
3) If someone suggests that you look at an example, DO IT! LV comes with a wonderful set of examples that demonstate almost all of the core functionality of LV. Familiarity with all of the LV examples will get you through about 80% of the Certified LabVIEW Developer exam.
4) If you have a question first search the examples for something tha
t may help you. If you can not find an example that is exactly what you want, find one that is close and post a question along the lines of "I want to do something similar to example X, how can I modify it to do Y".
5) Some of the greatest LabVIEW minds offer there services and advice for free on this exchange. If you treat them good, they can get you through almost every challenge that can be encountered in LV.
6) If English is not your native language, post your question in the language you favor. There is probably someone around that can help. "We're big, we're bad, we're international!"
Trying to help,

Msi Big Bang Xpower II can only run with 3 memory modules?

Hello there! I've just got my new system up and running. But it cant boot with 4 memory modules when there is a module in slot 7? I have a 4x8gb kit from corsair (CMP32GX3M4X1600C10), and a Msi Big Bang Xpower II..
When i start it, it just shows me the debug code "67" which is "Late Cpu Initialization" according to the "User Guide".. It stays there, for about 15 seconds, then it shuts down, and does the same, over and over..
Atm, i'm running with 3 modules, and there's no problems at all! I've testet ALL memory blocks, in another computer, and they run just fine..
What should i do?

Also, what cpu, bios version , memory type etc
Make sure the mem mods are in the proper slots for tri channel operation.
>>Posting Guide<<
If everything comes up clean, update to the most recent bios. Only do this if your computer is stable in bios. IE You are only having crashes in windows etc.

I am having issues with my web module on Lightroom 4 (Mac OS 10.9.5). "an unknown error occurred" while trying to upload to my FTP (no changes in my FTP). Bandaid fix was to export to local folder and upload via Filezilla. However, now that is no longer working and although upload completes, the URL takes you to a "Forbidden - do not have permission to read this file" page. Lightroom is changing the permissions of each file to 000 instead of 644 for index files and 755 for all others. How can I change the permissions settings in Lightroom?

I get an error message when trying to install windows 7 on my macbook pro. The message says "windows has encountered a problem communicating with a device connected to your computer. I don't have anything connected to my computer. How do I fix this?

I'm trying to install windows 7 on my macbook pro. I went through the process of bootcamp telling it to install windows 7. Once the windows boot manager started an error message came up. The error message says " windows has encountered a problem communicating with a device connected to your computer. I don't have a usb connected to my computer. I am using windows 7 professional install disc. I can't figure out what i am doing wrong. The same message keeps coming up over and over. Am I doing something wrong or is it something else?

Well, shucks, i just spent almost 30 minutes trying to find your model user guide to explain it better, I guess they never got around to making it.....
I would just borrow another Windows disk and try installing it again and if it does it again then you might take it to an Apple Store and see if one of the "Genius' " can figure it out.
Make sure your internet is enabled and click on your blank desktop and at the top of your screen is a Help menu option, enter PRAM and it should give you a list of things relating to Pram. It may take a few seconds to list anything as it has to connect to Apples severs first. It should list the things you may have to fill back in when your done.
"P-ram" stores some common information that is used in the background, your date, time, startup disk, etc, that you don't have to re-fill when you restart, it's a little different for each computer.
