S7 300 with labview 7

how can i scan "serial" data from the mpi interface of a siemens s7 300 with labview 7

Hello Fubu16,
From the following Link,
http://zone.ni.com/devzone/conceptd.nsf/webmain/CC021CD15890283286256A33006EBA74?opendocument
you can extract:
Siemens S7 PLC is a Profibus device that can communicate to a Profibus network through MPI protocol using Profibus interface card, such as an Applicom board. It can also be configured for direct connection with a PC using HMI Adapter, a device that translates MPI protocol into RS-232 protocol. To connect a Siemens S7 PLC to a PC, connect the HMI Adapter to the MPI port on the PLC, and connect the adaptor to the PC serial port using a null-modem serial cable
for more info on the HMI Adapter go to:

Communication via RS232 with a Kollmorgen Servostar 300 using LabView.

Hello,

Sorry I am new posting a message here and I post it before I was able to describe my problem.
I have a Kollmorgen Servostar 300 to control an AKM24F motor and I would like to send the instructions to the controller via RS232 using LabView. I think I had achieved communication from a PC to a Servostar 300 using LabView via the serial port.
So far I have setup in LabView the configuration of the RS232 (8 bit, no parity, baud rate 38 400), the address of the servostar (ADDR 0), the way the servostar should respond to the host (PROMPT 1) and the error flag (MSG 1), and no error had been detected when I run the program. I should mentioned that after I sent an instruction such as ADDR 0 terminated with a carriage return, I set a delay time of 150 ms, then I read the amount of bytes that are in the buffer, and then I read the buffer, as I mentioned no error message has appear and the ADDR 0 instruction is read from the buffer. Following the same procedure I sent an instruction to move the motor but nothing happens.
So far I am not sure if the way I am trying to communicate with the servostar is the correct or if I am missing something, any guidance that anyone my give would be greatly appreciated.

Siemens S7 300 PLC Communicationnd with Labview

hi;
I'm trying to connect my PLC s300 with labview in my PC .
How can I proceed ?
what is the easiest way to do the communication knowing that I did the simulation using TCP/IP protocol with OPC server.
I have SIMATIC net station and CPU 315 2-DP
any suggestion?
I want to use OPC server with MPI can I do so ? amI supposed to add materials and what are those materials ?
Thanking in anticipation.

Which type of command we need to ues. whether we need to form a MODBUS protocol command.
Siemens S7 supports all kinds of protocols. Some are built in from start and are usually Siemens specific protocols whose specs are not always easy to come by, others can be purchased and installed on the communication processor seperately such as Modbus. Once you have the Modbus library installed on your S7 you can simply use the Modbus VIs downloadable from the NI site to communicate with your S7 datablocks.
It is a strict IO access meaning you can read and write IO registers and memory datablocks, but not interfere with the actual programm on the S7 in other ways.
Using Modbus is simply and hard at the same time, since Modbus uses various datatypes with different address ranges that are mapped in some way to the items in the target hardware. This mapping can be tedious to work out correctly since the documentation of devices is sometimes quite a bit unclear about how exactly that has been done by the manufacturer.
There are many other Ethernet protocols that are available or can be installed on a S7 such as Profibus Ethernet, EtherCat, Industrial Ethernet, etc. Most of these while technically possible to be implemented on top of the native TCP LabVIEW nodes are rather complicated and therefore anything but trivial to create a VI library for.
Your best bet really is to either use Modbus or an OPC Server that implements the native access to the PLC.

Control izarc or winzip or winuha with labview

Hi.
I have a lot of data with my acquisition program.
The idea is to compress it to file it.
How can I make an automatic program with labview to compress datas with winzip or izarc or winuha or anything else???
It's very important for me because my data can be more than 4 Go then compressed less than 300 Mo !
Can somebody help me on this point???
Thanks in advance.

As the original developer of the OpenG lvzip library I just want to say
that it does make use of the zlib library internally. What I did was
merging the "zlib" library by Jean-loup Gailly and Mark Adler with the
"zip/unzip" code from Gilles Vollant and changing the export type of the
functions so that the same VIs could be used to call either a unix
shared library of that code or a Windows DLL version.
The next version currently under testing will support adding new files
to an existing archive, deleting files from an archive as well as
extracting password protected files.

I have siemens plc s7-300 and labview how can i communiction between plc and s7-300

Hi all good morning
iam new user for labview
now iam working one new projects with labview and s7-300 automation plc so how can i communication between plc and s7-300 using profibus or ethernet cables can any one help me with example
thanks
best regards
vijaynagar.

Dear vijaynagar,
it would be posible to communicate with our Comsoft PROFIBUS products like DF PROFI II, FNL or cRIO PB.
Please have a look at:
- DF PROFII: PCI, PCIe, C-PCI or PC104+ card with LabVIEW drivers: Link
- FNL: Ethernet/PROFIBUS Gateway: Link
- cRIO PB, C-Series module for National Instruments FPGA chassis: Link
The DF PROFI II can be bought directly from Comsoft, the cRIO PB can be bought from National Instruments.
Regards,
Sven

Interfacing Siemens Desigo PXC Building Automation controller with LabVIEW

Hello everyone,
I am currently trying to interface Siemens building Automation controller Desigo PXC100-E.D http://www.buildingtechnologies.siemens.com/bt/global/en/buildingautomation-hvac/building-automation...
with LabVIEW using OPC servers. I had once interfaced the S7-300 PLC of Siemens with simatic step-7 software with LabVIEW but in this case I don't which driver should I select and don't know is it possible or not. If any one of you have similar sort of expierence please I need advice..
Thanks

Hi,
As you have described I've done the whole configuration. I am using MatrikonOPC for BACnet and as I've checked my device and the software are working properly. Now what I am trying to is that I am connecting the BACnet OPC server with LabVIEW so that the MatrikonOPC act as a connection layer between my device and LabVIEW. So that I will be able to change values directly from my LV vi. Now when I connect that Bacnet OPC with LabVIEW using the same procedure for PLC it gets connected because it is showing all the tags from the device. But after doing the whole procedure which is the same according to the tutorial 'connecting LV to any PLC using OPC' when I deploy the variables I am getting some error. I am attaching the screenshot of the error. Please let me know if I am doing any thing wrong.
PS: I am using a virtual machine and I've tried the whole thing with the NI OPC servers as well according to the tutorial but still when i deploy variables I am getting this error.

Hi Guddan,
I created a RFC having a query which is taking a long time to execute. So i want to close RFC connection with portals which is via java connector(JCO) before that query and open the connction again after that query.
I guess i will need to understand your requirement a little more in detail, as i understand you have an RFC which has a query within to fetch some data and is taking a long time to do so. In the meantime you don't want to keep the connection open?
My question would be, Is the role of this RFC to only execute the query and fetch the data or does it do something else?
If it does other things and these are independent of the query execution, then you can span a parallel call within the RFC to execute the query and in the meantime the RFC does the other things (or vice versa) hence reducing the overall time taken.
If the sole purpose of this RFC is to execute the query, then you will not be able(i mean to say there is no simple and direct way of doing this) to close the connection after the Query is started and re-establish the connection after its execution, for a simple reason that - how will you know if the query has completed it's execution, so that you can establish the connection back.
Alternate solutions, make this a two way asynchronous call, 1) You invoke the RFC asynchronously and close the connection, the RFC in turn will execute the query and transfer the data to JCO via another RFC call.
If this needs to be a synchronous call, then you will need to optimize the query to its best.

Chen

Lost ActiveX connection with LabVIEW server

How can I create a scene and move 3D models in INSIGHT with Labview?

Hi!
I need some help in doing a LabView application. What i have to do is controlling a 3D model represented in Insight with Labview. Something similar like the six-axis-robot example. I follow the insight configuration wizard, but nothing moves. Comparing the ".cis" files in my program and the one from the six-axis-robot, i found that in the six-axis-robot file contains something called localsystem and the one made by me, doesn't. Can be this the problem? How can I make it work? I would need some kind of step-by-step response, because i'am a beginner with Insight and 3D models. Thanks in advance!

Thanks for the advice!
I'm actually finding the next problem. Although in my VRML file the objects are defined separately in a jerarchy tree, I can't move(rotate, translate) each object individually. I have noticed that when i define a new local system and asign it the points of the object i want move in the way you explain (right click, and then dragging the points to the new local axis), the movement of this object is dependent of the other local systems i have defined for other objects , specially if the slave nodes of the .cis file has a lower numeration than the object i want to move. The fact is, the movements assigned , for example to the nodes 1 to 100, will affect to the rest of the nodes if i also define for the rest of the nodes other movements. How can i solve this? I send you my .cis file, just in case my explanation is not enough clear. In this file you can see that movements assigned to nodes 1 to 4078, will also affect to nodes 4079 to 7168, and what i would like to do is define a movement for each obeject independently.
Thanks again!

Excel with Labview 6?

I'm trying to get Excel '97 to work with Labview 6.02, but I'm always receiving error message: -2147319784: "old format or invalid type library". I modified windows registry as told in LV knowledgebase. After that I could see Excel components in ActiveX pull down menus. I have tried to run demos such as "Open Excel And Make visible.vi" but they always output the error message. I have tried this with both Windows 2000 and NT. Other programmes, for instance MS Access, seem to work fine. What is the catch?

Anders,
You have run into a special case of the problem that actually has a work around for it. However, you will have to contact LabVIEW technical support to obtain the temporary fix since they need to keep track of all the people with this special case.

Hi Leo22,
Does this error occur if you use any of the example programs that come shipped with LabVIEW? I would try opening one of the examples that write data to Word and see if those give you an error. Also, have you tried just putting down a New Report.VI and change the report type to Word? If this simple vi (that's all you need to open Word) breaks, I would check to see if there are any instances of Word still open. Check the task manager to see if any word processes are still open. There should not be a problem accessing Word 2003 from LabVIEW 7.0. If neither of these solutions work, please give some more detail about your application and we can research further. Thanks!

Calling a VI which uses "system exec.vi" with LabVIEW run-time engine as adapter

Hi,
My TestStand sequence calls a VI which includes a call to "system exec.vi". When I try to load it in TestStand and if LabVIEW adapter is set to run-time engine, I get an error message "Unable to load Vi...". If I switch the adapter to "Development system", then it works fine.
Is there any way to use "system exec.vi" in a VI which is called in TestStand with LabVIEW run-time ?
Thanks,
Alex

How do you use Synergy 7.1 with LabVIEW?

My company has reciently installed and configured IBM Rational Synergy 7.1 to be used as our Source Code Control tool. I have installed the appropriate Microsoft Source Code Control Interface so that Synergy will show up in LabVIEW and it does show up in the "Source Control" options window.
However when I select Synergy as my source control tool it does the following:
1. Brings up the login window - I am able to login with no problem
2. Brings up a dialog allowing me to select the project to work on, and after I select the project I get two errors...
one from Synergy: "The workspace/project you want to add to IBM Rational Synergy is not under the work area path 'C:\xxx"
(where xxx is my work area for the Synergy project I selected)
then one from LabVIEW: "Error -2941 occured at prefPage_Source Control.vi An error occured trying to get the source control project path. Possible reasons: LabVIEW: The source control provider does not support the specified operation."
I first tried this on an earlier version of Synergy that matched what is being used in:
http://digital.ni.com/public.nsf/allkb/16D37CCC8659123F8625720500087DB4
But I was getting pretty much the same errors back then too. It seems like it should work in LabVIEW, I just have no idea what I am doing wrong!
Anyone out there successfully using LabVIEW with Synergy????
Thanks,
Trevor.

In theory if a source control provider supports the Microsoft SCC interface, it *should* work with LabVIEW. In practice, each provider has custom implementation that sometimes causes problems when trying to configure the provider from LabVIEW. One sticking point for many providers is the expectation or assumption that an IDE will use some concept of a "project" and therefore pass data associated with that project to the provider. LabVIEW does not enforce that concept but does pass valid information.
Synergy was tested back when it was a Telelogic product. It was difficult to configure and required exact steps to get it to work correctly. The linked knowledge base were steps taken that worked for a few customer setups. It's possible that on other Synergy setups the exact steps may not work. Also, you might check to make sure you try to configure existing Synergy projects and not try to create new ones from LabVIEW.
The error you mentioned seems to imply that some data is not supported by Synergy. I am not sure if Synergy would be able to track down the issue, but I would recommend contacting them to see if they can pinpoint what data LabVIEW is sending is not valid.

Create new WB with LV.vi ‏18 KB

You are not using the correct mechanism. Pull up the Example Finder in LabVIEW, click on the "Search" tab, and enter "Excel". Look for an example called "Write Table to XL". Use this as a starting point for creating new workbooks and adding data to it.
Note: on disk the example is at <LabVIEW install directory>\examples\comm\ExcelExamples.llb.

Windows 7 Compatability with Labview 8.0 and missing files while interfacing the FPGA with LV

I am trying to use an FPGA (PCI-7830R) with Labview 8.0. The computer has Windows 7 OS. I installed LV 8.0 in the proper order with the FPGA Module and labview is able to see the FPGA when I open a .lvproj (the FPGA is in the tree) however there is a warning symbol next to the FPGA selection and when I try to open a .vi file that is used on the other stations in my lab (it works on all the other stations), labview is unable to find a whole bunch of files. There are some pictures.
Missing File (there are a bunch more but this is the fist one).

According to this LabVIEW Compatibility LabVIEW 8.0 is NOT compatible with Windows 7
