LabVIEW with Siemens hardware communication

My application has Siemens AC Drive with Siemens PC CP5613 card being provided. Communication with the drive is thru' Profibus with LabVIEW. Does LabVIEW have a direct interface to communicate with Siemens CPS5613 card.

Hi!
No, unfortunately direct communication between LabVIEW and this card is impossible. (Theoretically you can looking for examples, which delivered with this card and calling DLLs for accessing, r/w Dual-Port RAM and so on, directly from LabVIEW, or over DLL-wrapper, but this not very easy). So, better way - using OPC server, which normally delivered with this card. Over OPC you can get access to Profibus. You can use OPC.SimaticNET server, or OPC.SimaticNET.DP (inline) server. Better way - using over LabVIEW DSC, but you can also to get acces over DataSocket without DSC (if you have not more than 30 items for reading and writing)
With best regards...

Error communicating Labview with Fieldpoint hardware

Hi,
I run Labview in conjunction with the Fieldpoint hardware. Upon reinstalling the labview program after a computer crash, I am no longer able to re-establish the communication with the Fieldpoint hardware. It seems to be a driver problem but I am not able to pin point exactly the problem. This is the error message when the software "SHIME" was run:
Error 7 occurred at Open File+.vi: Open File.
Possible reasons:
LABVIW: file not found. Or
NI-488: non-existent board.
I greatly appreciate any suggestions for trouble shooting.
Sincerely,
Trisna

Hi Aaron,
thanks for the advice. In fact I was just trouble shooting the problem with an advisor/technician from National Instruments and he confirmed the same thing that there is no problem between the communication of the computer and Fieldpoint. It is more of the problem with the software itself. I am running a software called "SHIME" that stands for simulated human intestinal microbial ecosystem but I couldn't locate any open.vi or auto.vi file on the CD; you mentioned looking for something in the software.
I am communicating with the people who sold us the SHIME system and I appreciate your advice.
Sincerely,
Trisna

Interfacing LabVIEW with SIEMENS s7-300 PLC

Hi all,
Im using LabVIEW 8.6 and DSC module I want to interface S7-300 SIEMENS PLC with LabVIEW. I've gone through the turorial on the NI site " Connect LabVIEW to any PLC". By following the tutorial when I am trying to create I/O server in the registred OPC servers window there is nothing what would be the reason. Also there is no specific information available about the hardware connection etc. Kindly help me through this or suggest some tutorial links. What about the PROFIBUS and MPI. I know the information i am giving is not specific and focused but I've tried to tell all of you to atleast understand what I want to do. Hope you people help. THANKS.

Hi,
Lookout is our legacy OPC software that was phased out by the DSC module. You can read about both here: What is NI Lookout? and What is DSC?
You can find a great introductory DSC tutorial here: Getting Started with the LabVIEW Datalogging and Supervisory Control Module. A couple other places to get started: NI Module Training (look for DSC) and Connect LabVIEW to Any PLC Using OPC Webcast
As for simulating your hardware, if you have a 3rd party simulator that will imitate your hardware, you might be able to fool DSC into thinking that there is actual hardware connected, but DSC does not include simulating capabilities itself.
Cheers,
Misha

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.

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.

Spartan 3E with Labview 2012 (32 bit) on WIndows 7 64-bit - Error Code: -310602 NI-COBS: Unable to communicate with device over communication cable.

Thanks for the info, Kyle. I will probably try to find an older 32-bit XP machine. VM is just not an option for me right now.

Hello everybody,
I am trying to use the DIgilent Spartan 3E board with Labvew 2012 SP1 32 bit. I am able to compile the example code for LED shift. I am however unable to transfer code to the FPGA. I get the following error message:
Error Code: -310602
NI-COBS: Unable to communicate with device over communication cable.
Please verify that the cable is connected to a supported device and that the appropriate drivers are installed.
My system configuration is as follows:
Windows 7 (64 bit) on Dell XPS laptop.
Labview 2012 SP1 (32 bit)
Labview FPGA 2012 SP1
Labview 2012 FPGA support for Spartan3E
Xilinx 13.4 tools
DEFB LV FPGA 2012sp1 support installer
Xilinx USB cable driver v1.3 installed.
I took all the precautions mentioned by others on this forum and others, mainly that the cable must be disconnected before installing the Xilinx cable driver. All software and drivers were installed correctly. I even uninstalled and reinstalled the entire Labview software set I had. I still get the same error.
A few other questions:
1. Is the Xilinx cable different from a regular USB cable of the same configuration ?
2. When I program the FPGA I only have the USB cable connected between my computer and the Spartan 3e board. Should any other cable be connected ?
3. What should be the correct jumper settings for J1 - JP30 (especially J30, J11, JP9, JP6, JP7, etc) ?
I have been at this or over 3 days trying to figure it out. Any help will be greatly appreciated.

Could you pls expalin me how to solve visa error 1073807246, I am serial communication with the hardware. thanks

Hardware :- light modulator

Here is the definition of the error from LabView:
"VISA: (Hex 0xBFFF0072) The resource is valid, but VISA cannot currently access it"
Are you able to communicate with the hardware manually using a sw like "HyperTerminal"? If so, configure the serial port setting to the same as that to communicate manually.
It appears that you are using a valid comm port, but it cannot talk to the hardware for some reason. It could be as simple as a bad connection (wiring / soldering / etc) to the hardware.
The first thing I would check is the ability to communicate manually. If it works manually and you duplicate the settings, it should work. If you can;t communicate manually, then you'll have to do some troubleshooting..

How can I connect LabView with a PLC S7-300?

I want to use LabView with a PLC S7-300. I think I can use a PC card or RS 232 with a HMI interface.What is the difference? I think I need an OPC server (I don´t know who sell it, National Instruments or Siemens) and I don´t know if I need anything else than LabView6i.
Thank you.

Alicia,
Ben's answer is absolutely correct. "Profibus" is the key word here, and a search of "profibus" from ni.com will provide quite a bit of information. I went ahead and pulled out the main items below. Follow the link below for product catalog info on the plug-in cards and interface software (the OPC Server) required.
http://sine.ni.com/apps/we/nioc.vp?lang=US&pc=bymn&cid=1315
For a step-by-step configuration tutorial, please follow this link:

And finally, for examples on how to communicate with this OPC Server, or any other OPC Server for that matter, LabVIEW has some shipping examples. From LabVIEW, goto "Help >
> Communication >> Datasocket OPC". A good one here is the "Demo OPC Client" program, which uses a software OPC Demo Server that installs with LabVIEW. You could pull that open and work with the LabVIEW programming now before you even have the hardware.

Sample Project with ni hardware using NI-DAQmx Driver

I would like to use DasyLab for a research project with Siemens PLC

I would like to use DasyLab with Siemens PLC Simatic S7-300. Which OPC Server shall I use?
I would like a manual for connecting DasyLab via OPC server to the PLC if it is possible.
Could I use NI OPC Servers which are compatible with LabView?
Thank you for your help

I believe that Siemens has an OPC server that you can purchase.
KepWare has the KepServer and drivers for Siemens www.kepware.com.
DASYLab has the Help menu with the instructions for the OPC DA modules. It's straightforward - configure the OPC server with the necessary drivers and connections (tags). Update rates are in milliseconds, for example, 100 ms is typical. You need to know your device and driver, to determine data types.
Once configured, KepServer has an OPC quick client to allow you to test your settings.
Then, add the OPC DA module to DASYLab, connect to the server, and select the tags to read or write.
Note that it's simple to set up on a single computer - to set up on multiple computers requires assistance from your It team to correctly configure the DCOM permissions. That's specific to the OPC server.

Link labview with other software which can do hydraulic simulation such as Nanas Fluent.

   Hi all:
          I currently want to exchange data between labview with Ansys fluent. That is: sending flow boundary condition and initial condition from labview to hydraulic simulation software (ansys fluent), and get simulation result back to labview from that software.
         I didn't find any modules online to link labview and fluent together. (There are others such as Labview Solidworks module)
         Is any one know how to link labview to any software which can do hydraulic simulation?
         Thank you very much. :-)
-Bowen

Do you know of any other programs that exchange data with Ansys? If so how do they do it? ActiveX is a common way for communicating between LabVIEW and other programs, is this an option?

Hi G-Money,
The communication will be over TCP-IP.
Thanks for your offer to help. I don't really need assistance in figuring out how to communicate with the device in LabVIEW at a transport layer. I'm just trying to take inventory on what's already been done, at a messaging protocol level, that could be useful as a reference or starting point.
Thanks,

LabVIEW with Git

Hi all,
I'm in the FIRST robotics community, and next year we're getting a copy
of LabVIEW 8.6 Pro which has the a few programs included for use in
source control.
Anywho, we're interested in using some sort of source control to keep
track of our code and allow simultaneous development with several
programmers. A quick Google search shows little or few relevant results
of using LabVIEW with Git.
I'm wondering if any of ya'll, LabView users, have ever used Git for
tracking your code? If so, how have you accomplished it? If not, what
have you used that is free to use?
Any information would be helpful.
Thanks
-Tanner

I read about TortoiseGit, a clone of tortoiseSVN/CVS for Git, maybe you can configure (and test) the merging and differencing a little bit easier.
Here is a howto to use tortoisesvn and LabVIEW merge.

Labview with industrial robot connection

Hi,
I am in the field of industrial Robots Automation and I am impressed with Labview. So I am plannig to use this as HMI for our industrial robots. Can you please tell me is it possible to connect labview with ABB, Commau, Motoman, Fanuc and KUKA. If yes can you please send me the details.
I saw a third party software called imagin lab but they are doing only for kuka, denso and mistibushi.
Thank you

You've listed 5 different robot types, and while I'm sure that if those robots are able to communicate with any outside resource they'll be able to do so with LabVIEW; they are five different types of robots and will probably require different LabVIEW solutions for each.
The robot model and the specifics of exactly what type of communication you're looking for are also required to know "how to do it."
A couple of quick searches tell me that OPC may be required for some of the robot types you listed. A good place to start with that is here: http://www.ni.com/opc/
Without the specific details it will be difficult to locate an existing solution.
If a custom solution is required, you may be able to find some assistance creating one on the forums. But again, details will be requried.
