Interfacing S7-300 PLC with OPC variable not having any value

Hi, i am trying to interface a Seimens S7-300 PLC with LabVIEW with the MPI protocol. I followed the webcast "Connect to any PLC using LabVIEW". There are 2 problems that i face,
1. There is a Timeout Dialog Box which ofcourse times out the connection to the PLC. This allows a max time of 30seconds. Can i increase the Time out in any way?
2. When i create a variable as shown in the webcast, it does not have any value nor does it have a time stamp value as the variable in the webcast. I am uploading a picture here to make it clear. I wanted to know why does this happen? It does display the system variable values as being valid and also updates them.
Thanks.

Hi David,
This is the webcast i am talking about
http://zone.ni.com/wv/app/doc/p/id/wv-263
I am using LabVIEW 8.6, NI OPC Servers to connect with an S7-300 PLC using the MPI protocol. Following the procedure outlined in the webcast:
Opened OPC servers:
1.Created a Channel.
2.Cose the device driver.
3. Set the serial communcations settings(Baudrate etc) according the configuration settings of the PLC.
After doing step 3 i get a dialog box asking me to set the time out period of the PLC (which i set to 30 seconds i-e the max that was allowable). I also set the write attemps before failure(which i set to 8).
4. Added a Device and gave it an arbitrary name.
5. Chose the device model.
6. Set the Device ID to 1.
Than i added a tag. Gave the name Input, the address of the input and all(which was accepted by the OPCServer).
After creating a tag when i open the OPC Client, all system variables are displayed as being valid and also get updated but the tag i created has no value and there is not updating taking place as indicated by the time stamp. I will change the tag and also see if i can upload a video of exactly what i am doing.
Thanks for your reply.

I want to interface PCI-6601 with photoelectric sensors to count the number of PCB chassis.

I want to interface PCI-6601 with photoelectric sensors to count the number of PCB chassis. Related this I have following problems-1)Where I can connect sensors(pin numbers)?
2)How I can acquire data from that sensors(Is is necessary to write any program? If yes, what?)
3)In which format I will get the output data?

Hi,
We're going to need a little more info about your application before we can get you a compete answer.
Your 6601 is a counter/timer board that can count and measure TTL pulses.
You can get the pinout for your board from the user manual found here: http://digital.ni.com/manuals.nsf/websearch/dd0dbb6404bc139886256721007cf16d
In LabVIEW, you can find shipping examples for various counter measurements by going to Help >> Find Examples >> Hardware Input and Output >> DAQmx >> Counter Measurments.
I would also suggest downloading and installing the latest NI-DAQ driver:

Plc PROGRAMMING +LabView programing

Hi ,
    Can anyone please tell me if we can get PLC functions from LabView itself ,if,yes,how should we proceed for that ?
Thanks & Regards !

Hi!
    Do you want to interface PLC programming languages code (IEC 61131-3) with labview or you wish to translate a sw written for a PLC to labview? In the first case I don't know if it is possible, you can interface C code, and import dlls, but I don't know about importing FBs or something similar.
   Anyway, I think Labview is similar to FB programming... expanded. Some main concepts hold in both languages, while Lv gives you more possibilities, hence it's slightly different; but I'm confident you can become familiarwith labview quickly.
   I don't know if I answered your question (maybe implicitly? ). If this is not the case, please tell me more. And one important thing to know is: what is your target? Are you developing an application for a PC, an embedded, FP...?
   have a nice day!

MAX shows my GBIP-USB Interface, but no communicatin with Labview

I'm using a GPIB-USB(Agilent) Inferface to communicate with my devices.I Install the drivers form agilent and Labview 6.0.2. MAX 2.0 does not show me my USB-GBIP Interface and no devices. So i have download MAX 2.2 and now i can communicate with my devices. The problem ist, that i can't open the VISA session in LABVIEW, so that i can't communicate with my devices. I try to open the NI-Spy, but it show me an error. Have erverybody a idea how can i solve this problem. THX

===========================================================
I understand you want to control GPIB instruments using NI LabVIEW, NI
VISA, and the Agilent 82357A USB/GPIB Interface.
This method works for me. Perhaps you can compare your results to
this procedure, and then make progress.
1. Starting Conditions:
I start with my HP Kayak XU800 PC (single 800 MHz CPU), with an NI
PCI-GPIB+ card installed.
My Agilent 82357A USB/GPIB Interface is not connected to PC nor
instrument.
The attached Visagpib01.vi LabVIEW program is on an uninstalled floppy
disk: A:\Visagpib01.vi
I format the C: hard disk and install Windows 2000 Professional. I
reboot.
Windows runs a Found New Hardware Wizard (for a PCI Simple
Communications Controller). I assume that is for the NI PCI-GPIB+
card. I click the Cancel button. I'll run a similar wizard AFTER I
install the NI software.
2. Install NI-488.2 for Windows:
I put in my NI-488.2 for Windows CD (July 2000, 500739E-00) and let it
autorun. I click on "Install NI-488.2 Software for Windows". I use
the default Destination Directory: C:\Program Files\National
Instruments\NI-488.2\ .
I choose the default "Typical" installation, and complete the
installation.
Now I click on "Explore CD" and run the "SetupVisa" icon to install
NI-VISA 2.5 . I use the default NI-VISA Folder: C:\VXIpnp\ . I
choose the default "Complete" installation, and complete the
installation.
I click the Yes button to reboot my PC.
Now that I have installed the NI software, the NI-488.2 Getting
Started Wizard runs. I click on "Verify your hardware and software
installation". It found my NI PCI-GPIB+ card as GPIB0. The Agilent
82357A will not be visible yet. I click the Exit button. I'm done
with this NI-488.2 Getting Started Wizard, so I click the x in the top
right of the window.
3. Install Agilent I/O Libraries for Windows:
I put in my Agilent I/O Libraries for Instrument Control for Windows
CD (L.01.00) and let it autorun. I click the Next button a few times
until I see 2 big buttons: Full Installation & Custom Installation.
Because this is the L.01.00 release and I installed the NI VISA first,
either button would work. But I'll be precise and click the Custom
Installation button. I use the default Destination Folder: C:\Program
Files\Agilent\IO Libraries . I choose "SICL and side-by-side Agilent
VISA Installation". This will leave the NI VISA as the primary VISA,
and install the Agilent VISA as secondary VISA. After a few clicks on
the Next button, it says the Agilent IO Libraries have been
successfully installed. I choose neither View Readme nor Run IO
Config. I click the Finish button.
Some Operating Systems may require a reboot here. My Windows 2000
does not.
4. Prove NI VISA is Primary VISA:
Start button - Programs - Accessories - Windows Explorer. Browse over
to and highlight My Computer\C:\WINNT\system32\visa32.dll . File
pulldown menu - Properties - Version tab. My file is National
Instrument's VISA Library 2.5.0.0 .
I click the Cancel button. File pulldown menu - Close.
5. Plug the 82357A into the PC:
I finally plug the 82357A into my PC's USB port (any USB port). The
standard 82357A live configure window pops up: "Agilent 82357A
USB/GPIB Interface Detected". Because Agilent VISA is installed, the
VISA Interface Name defaults to "GPIB0". Because I know I already
have a GPIB0 (my NI PCI-GPIB+ card), I click the Edit button and
change the VISA Interface Name to GPIB1, by clicking the nearby little
up arrow. I click the OK button.
6. Configure NI Software to Recognize Agilent Interfaces:
Start button - Programs - National Instruments - Measurement and
Automation Explorer. I click the OK button because I don't care when
MAX searches for new devices. Tools pulldown menu - NI-VISA -
Passport Editor. I put a checkmark in the "NIVisaTulip.dll - VISA
Library Passport for Tulip" line. I click the OK button. Because I
changed a setting, I need to click the OK button again. File pulldown
menu - Exit to exit MAX.
7. Access an Instrument through the 82357A:
The Agilent 82357A USB/GPIB Interface should now be accessible from
NI-VISA. With my 82357A plugged onto my HP 34401A Multimeter, Start
button - Programs - National Instruments - VISA - VISA Interactive
Control. Below the "GPIB1 (hpib7, 82357)" line, is a line for my
instrument, "GPIB1::23::INSTR". I double click on that "INSTR" line
to pop up a session window. Basic I/O tab - viWrite tab, I click the
Execute button to write the default "*IDN?\n" string. viRead tab, I
click the Execute button to read the expected
"HEWLETT-PACKARD,34401A,0,5-1-1\n" string. I'm done, so I click the x
in the top right of the window. File pulldown menu - Exit to exit the
VISA Interactive Control window.
8. Install NI LabVIEW Evaluation 6i:
I put in my NI LabVIEW Evaluation Software for Windows 2000/NT/Me/9x
CD (version 6i, 350778A-01) and let it autorun. I click the Install
button. Eventually I choose the Complete installation. It says
LabVIEW 6i Evaluation has been successfully installed. I click the
Finish button. Eventually I click the OK button.
9. Run the attached Visagpib01.vi LabVIEW program:
Start button - Programs - National Instruments LabVIEW 6i. I click
the lower left RED Start using LabVIEW button. I click the Open VI
button and enter the File name as A:\Visagpib01 . I close the
Controls and Tools palettes by clicking the x in the top right
corners. Notice the resource name field of "GPIB1::23::INSTR" to use
my GPIB1 82357A connected to my 34401A at GPIB address 23. Operate
pulldown menu - Run, and the read buffer field now says this expected
string: "HEWLETT-PACKARD,34401A,0,5-1-1". Running the example again
simply writes over the earlier string, and so does not appear to
change the display. The attached Visagpib01.vi LabVIEW program is
simplified from the "C:\Program Files\National Instruments\LabVIEW 6
Eval\Examples\instr\visa\SRQ Event Handling.vi" NI example program.
I attach 2 GIF files to describe the attached Visagpib01.vi program:
Visagpib01_panel.gif
Visagpib01_diag.gif
I hope this helps!

I want to use Get Panel Image in Labview 5.0.1 and need details on how to save the BMP data generated

I am trying to generate an application that saves a copy of its front panel on completion. This is easy to do using an invoke node with Print VI to HTML but this does not work in an .exe format. I have seen elsewhere that you have to use the Get Panel Image method, but no details are supplied in LV 5.0.1 documentation of how to use the "image" data (1-D Unsigned Byte array) that is generated. I want to save this in a format that can then be read as a bitmap in any standard graphics package. Any assistance?

Hi,
If you'd upgrade to LV5.1 or 6 you could use the 'standard' vi's for this.
You need a VI called "Write BMP File.vi". It's not shipped with LV5.0.1.
This vi only uses 3 subVI's, so perhaps someone at NI can convert it and
send it to you (sorry, I won't, it's copywrited).
If you cannot get this VI anywhere, you'll need to figure out the BMP file
format yourself. It's not too complicated, but still could take some days.
Perhaps someone figured it out before LV5.1 was released.
Regards,
Wiebe.

Is it possible to create a schedule in Labview . Example: i want to off the lights at 7pm and want it on at 8am. If there is can anyone teach, its for a school project. Im using labview 2011

Since this is a school project I recommend you do the work yourself. You will not learn asking others to do it for you. In addition, folks here will not do your homework for you. We are however more than wiling to answer specific questions for you. Post what you have done or tried and ask specific questions. I am confident you will get assistance.
And to answer your question, yes LabVIEW can be used to implement a scheduling program.

Replacing a PLC with LabView Article

I just read the article "Replacing a Programmable Logic Controller (PLC) with LabVIEW and FieldPoint for Composting Plant Automation ". I am very concerned by the author's lack of knowledge about current PLC's. This article does not fairly compare the two platforms and is not accurate. For example, the author states that 100 msec is a typical response time for a PLC. This is absurd. Today, even low end PLCs can achieve responses time below 10 msec and high end PLCs even as low as 1 msec. It all boils down to specifying the right hardware for the application. One real danger the author does not address with building a "soft PLC" is the potential for the I/O not to fail to a safe condition if the operating system (Windows) lock
s up. This can be disastrous and unsafe for many control applications. I would suggest any reader that is seriously considering replacing a PLC in an industrial environment with a "soft PLC" watch out for this potential shortcoming. Readers can visit www.isa.org to find additional information on this issue.
I would not dispute that for a pure data acquisition application LabView can offer a superior solution. The safety conern can be mitigated if there is a "hard wired" safety system that has been properly designed. However, many times the PLC may provide safety shutdowns that depend on its true deterministic operating system and high reliability.
I hope that readers will not interpret this as a slam against LabView but as encouragement research this issue further from a different perspective.

I can see from your comments that you have a firm grasp of the PLC/vs PC concept, and agree with your comments. I have been an instrumentation developer/integrator for 36+ years, and have first hand experience with the situation(s) to which you refer. I have found the optimum solution has been a combination of PC/MMI software and PLC hardware. I have many such systems up and running in different industries, and have found this to be the best overall solution. Let the PC do what it does best(MMI display, complex calculations and decision making), and the PLC what it does best(solid deterministic control, with a non-windows operating system). I usually use an OPC server for communication between the two units, and with proper software design on both ends,
and a hardwired E-Stop system, excellent overall opertion/safety is achieved.
Your comments should serve as good stimulus for other developers.

I want to make a web page using labview.

I want to make a web page using labview. I have the internet tool kit. Where do I start. Till now all I have used labview is for industrial I/O and mmi. I have used various TCP UDP comms for network purposes, but I haven't ever done anything with Web page design.

The internet toolkit has some functions for generating and manipulating HTML, but it isn't really intended as a Web page authoring tool. I personally wouldn't use it for such a purpose, and I've done a good bit of Web programming in various different environments, including LabVIEW.
The true power of the internet toolkit lies in its ability to create LabVIEW VIs to handle CGI requests, the way that perl or PHP might be used in more traditional Web development. In the old days, this was really the only way to provide Web interactivity with LabVIEW on the back end. Here is a document that outlines how to start up the toolkit's Web server and check out the CGI examples that ship with LabVIEW. This is the best jumping-off point for creating your own pages, if you are planning to use the CGI functionality in the internet toolkit. Just examine how the HTML pages and the CGI VIs in the examples work together and begin to try out your own VIs.
Since LabVIEW 6i, LabVIEW has shipped with Remote Panel functionality that allows you to publish any LabVIEW VI in a Web browser without the burden of creating special CGI functionality. Furthermore, users can fully interact with the VI--buttons, graphs, string controls, etc. That's really a better solution if you want to make VIs available via the Web and aren't so much interested in CGI/transactional behavior. Check this out by choosing Tools >> Web Publishing Tool from LabVIEW.
I hope this info gives you some ideas about starting points for Web functionality in LabVIEW. Please follow up if you have more specific questions.
Best Regards,
John
