Plc data logging using Labview

I am trying to communicate with PACSystem RX3i using Labview in order to log
data from PLC. Is this possible?
If it is possible, how could I implement it?

Hi mber,
Thanks for posting at NI forums. I looked into the supported device & driver plug-in list for NI OPC Servers, and the PACSystem RX3i is supported. To configure the OPC server to communicate with this PLC, you can follow the steps given in this article. In the LabVIEW side, you can configure an I/O server as an OPC client to communicate with the server.
In order to configure the I/O server you will require the Datalogging and Supervisory Control (DSC) module installed for LabVIEW. In the article I just referenced, it shows how to configure bound variables to communicate with the PLC tags to retrieve data. The DSC module installs a Citadel database, so when you are configuring the bound variable, you can choose to log data depending on events, alarms or a historical log. This article describes the data logging options using the DSC module. You can also choose to read and display the data in a VI by dragging the bound variables to the block diagram and then log to a file using logging functions.

    I can think of two possible stumbling blocks:
    What are your 8.6 options for "byte order" and "prepend array or string size"?
    Overall, many file IO functions have changed with LabVIEW 8.0, so there might not be an exact 1:1 code conversion. You might need to make some modifications. For example, in 7.1, you should use "write file", the "binary file VIs" are special purpose (I16 or SGL). What is your data type?

  • Acquire, analyze and data log using statemachine technique

    I am learning state machine technique to develop code for data acquisitoin and logging. I think I have written the correct code for this purpose but I couldn't get the following done:
    All warning values(>0) should be displayed on 1d array on front panel. The code is writing only the first value.
    All values should be logged using write to spreadsheet pallete and be written on excel sheet. Code is only writing first value.
    I wonder what's the mistake. The code I've created is attached, I'd appreciate if anyone correct the code and post in reply.
    Many thanks in advance for help

    Hi kwaris,
    "what's the mistake": Well, you use a lot of unneccessary conversions. Really a lot of...
    Why do you convert a scalar to dynamic, then convert to array, then index an element of the array? Why do you convert to dynamic when all you needis a simple "build array" node?
    Ok, I included a shift register to store your array. It's only a simple "how to", but not the best solution for all cases. But it should give you a hint...

    There is a database toolkit for LabVIEW.  I don't think it is a free download however.  With the Data Manipulation toolkit, you can integrate with most databases that use the ODBC protocol.
    If you don;t need anything fancy, you can write the values out to file using the write/read spreadsheet VIs.  If the file is [COMMA] or [TAB] delimited, you can import it into your database with ease.
    Another approach is to format you output to a text file as SQL, and import the records that way.
    INSERT INTO TEMP_HUM_TBL (Temperature, Humidity, Txn_Date)
    VALUES (30, 95, 'Dec-24-2013');

  • Data logging using Blue Thooth

    Hi Kjeld,
    I haven't yet tried to break it, but here are the steps I used to get the Simple Bluetooth Server.vi/Simple Bluetooth Client.vi to work...
    1) I inserted a BT/USB dongle in a USB port of my desktop computer running WinXPsp32. WinXP detected the new USB device and loaded the BT drivers to support it:
    Microsoft Bluetooth Enumerator v5.1.2600.2180
    USB Bluetooth Wireless Adapter v5.1.2600.2180
    2) I inserted a second BT/USB dongle in a USB port of my laptop computer running WinXPsp2. WinXP detected the new USB device and loaded the same version drivers as the desktop system.
    3) Opened LV8.0 on the desktop system and ran Simple Bluetooth Server.vi. VI correctly lists the "My Bluetooth Name" as the name of the my desktop computer, displays the hardware address of the BT dongle and the channel number. (Is this where your app fails?)
    4) Opened LV8.0 on the laptop system and ran Simple Bluetooth Client.vi. I entered the hardware address of the desktop BT adapter and the correct channel number. By the time I finished entering the hex values, 30 sec had passed and the Simple BT Server.vi had to be restarted, as it had timed out and stopped.
    5) After restarting the Server.vi, I started the Client.vi and --- magic.... it works as advertised.
    Is this similar to your experience?

  • How to data log graphs using front panel data logging?

    Hello I have a VI that collects data from DAQmx thermocouple readings and graphs the temperature vs time using a while loop to collect data and graph. I have 9 control operators that define the correction factor of the thermocouples.
    I want to create a datalogging using the option under Operations>Data Logging
    When I retrieve the data the only information that is present are the control operators correction factors that I defined. The graphed data that was created is not retrieved.
    Is there a solution to show the graphed data plots that were created on the front panel? They remain unchanged from the last run of the VI or blank if I open the VI without having ran the program.
    Thank you.

    This is expected for the Data Logging in LabVIEW. If you want to record the signla data, use the Write to Measurement File Express VI.  Here's a link with a walk-through:
    http://www.ni.com/academic/students/learn-daq/data-logging/
    The Data Logging from the Operate Menu is for recording front panel control(s), as you have observed.

    however most labview tutorial only teach you how to program with labview; the basics. But none elaborate on how to implement complex data structre like Queues, list, threes, or recursion. That is actually what I want. Same like we observe with other text books for c,c++ and java.
    That's probably because LabVIEW does some of these for you.  I remember learning the different sort algorithms and how to implement them with trees and other methods.  It was all good for academics, but when it came to the real world just use the built in sort function.  Same with queues.
    If you are sick of the beginner LabVIEW stuff I suggest going to a local user group to try to learn from others.  These generally are an intermediate step after you've master the beginner stuff.  There are official coarses that go beyond beginner stuff, but they too likely won't focus on algorithms.  More often these coarses explain how to make large scale applications, or how to design an application to scale up without painting your self into a corner.

  • HELP!!! Using LabView to display/control Mitsubishi FX series PLCs

    Hello,
    I am a LabView novice and have some questions around using LabView to control and display information from several laboratory instrumentation with a Mitsubishi FX series PLC. The communication protocol for the PLC is Profibus. What LabView modules/products do I need? Will I be using the OPC server and client to communicate to the PLC? Will I be using the device drivers? Is the device drivers the same as the OPC server. Will I need a profibus network card in the PC for Labview to communicate to the PLCs. Once again, I am a novice so please be patience if I ask more questions to understand your response.

    Hi,
    The following thread seems to address a similar query:
    http://forums.ni.com/ni/board/message?board.id=170&message.id=27248&requireLogin=False
    To answer some of your other questions:
    1. You'll be communicating with the Mitsubishi hardware using an OPC server.
    2. This isn't the same as the device drivers, though it could be included with the device drivers you got from Mitsubishi, you would have to check that with them.
    3. I don't know if you need a profibus network card in your machine, again, you'd have to check that with Mitsubishi
    NI do provide OPC software but I'm not sure if your device is supported. Check if it's listed in the following supported device list. If not you should be able to get an OPC server from Mitsubishi. According to the thread linked above they have one that's compatible with LabVIEW.
    The software NI provides that can communicate with OPC servers is called the Data Logging and Supervisory Control Module. What LabVIEW software do you currently have?
    I would advise that you contact Mitsubishi to make sure you have all the necessary hardware first. Also, ask them about the OPC server software. Then you can work on controlling the PLCs with LabVIEW.
    I hope this clarifies things but if not, post some more questions.

  • Data logging optimization function in LabVIEW and SignalExpress

    Hello, everyone!  I and a colleague have assembled the attached VI,
    which is used to control a plant growth chamber, and I could use some advice. 
    I would like to add data logging capabilities, ideally to note (1)
    environmental conditions, such as temp and CO2 level and (2) when certain
    situations occur, such as high CO2 or low pressure (which results in a change
    to the “Case Structure for CO2 and Pressure”).
    The chamber runs for weeks at a time, though, so I have a constraint.
    Instead of continuously logging all the environmental data (which would yield
    giant file sizes), I want to be able to take “snapshots”, say every 5 minutes,
    so I can examine the chamber’s condition over a long period of time.
    I attempted to use the Time Delay function to control the Write Measurements
    function (as in LabVIEW’s Cycle Analysis example, which I’ve also attached),
    but Time Delay halted my entire program. 
    I also tried the Wait (ms) function, but had no success.
    I recently discovered the powerful data review and reporting tools that
    SignalExpress has to offer.  Ideally, I
    would like to use a SignalExpress express VI to record the measurements instead of the more primative Write Measurements, but, I’m not sure how to implement this in my VI.  For example, would I make a data acquisition VI in SignalExpress for all my sensors, export to LabVIEW, and use that to replace the current DAQ structure in my VI?  (Because the chamber VI is interactive, I'm pretty sure that porting the LabVIEW VI to SignalExpress wouldn't work out well.)  And I’m
    still not sure how to control how often it records measurements.
    Any advice would be much appreciated!

    Hi, Sarah.  Yes I definitely plan to use LabVIEW for the majority of my data acquisition and logging.  I apologize, I think I probably should have broken my post into two separate posts for clarity, as my major concern is being able to set how often LabVIEW logs the environmental data (viewing the logged data in SignalExpress would be nice, but not a requirement).
    As I explained before, I'd really like to be able to set up a system that records the environmental condtions at regular time intervals, say every 30 minutes, or if my "Case Structure for CO2 and Pressure" status changes (such as from "Normal Conditions" to "High CO2".
    As an example, attached is a boolean structure (TimedWritedMeasurements.vi) that I came up with to record a simulated signal every 5 seconds (5000 ms).  Once I can get it to work, I would connect the boolean to my environmental sensor outputs and CO2 and Pressure case structure in my Chamber VI.vi that I attached in my first post.
    My problem is I can't seem to get the Trigger and Gate function to work the way I'd like.  I'd like the Wait (ms) function to trigger the Trigger and Gate function every 5 seconds to change the case structure in the TimedWriteMeasurements.vi to "True", thereby causing the Write Measurement function to record the environmental conditions.  Then I'd like the case structure reset to false, until it's triggered to true in another five seconds.  Can anyone point me in the right direction?

  • Using LabView to create a GUI for Delta PLC

    Hi,
    I'm currently using a Delta PLC, programmed with the Delta WPL software, and I'd like to use LabView to create a very simple GUI which would allow the user to communicate with the PLC (basically, the PLC would be running but doing nothing til the user writes data in one of the coils). I don't know how to do that, and I don't even know if it's possible ?
    The PLC I'm using supports Modbus. I tried to use the Modbus library from LabView but I'm not sure it's useful for what I'm trying to do.
    Any idea ?
    Regards,
    Coline

    The Modbus library can certainly be used to read and write registers and coils. You just need to know the relevant details for your PLC (address, coil addresses, ASCII/RTU, etc.) and to make sure the PLC is configured to accept these commands.
    The Modbus library should have a couple of examples showing how to act as a Modbus master, which is what you want.
    Try to take over the world!
