• "MB Ethernet Slave Demon.vi" connection lost when opening a windows dialog box in my application

  Hello everyone,

  I am currently working on a LabVIEW application that communicates with a PLC using a Modbus Protocol (with an ethernet cable). The PLC is the master and the PC is the slave.

  The code is based on the Modbus of LabVIEW examples: "MB Ethernet example Master.vi, MB Ethernet example Slave.vi and MB Ethernet slave Demon.vi. It is not the first time I use it.

  But I recently discovered a problem. In my application, I have a pop-up with a button that opens a windows dialog box to select a result file.

  When the windows dialog box opens, the "MB Ethernet Slave Demon.vi" crashes (I put a meter inside to see what happened and it stops at the moment opens the dialog box), then when I close the dialog box, the counter continues to count, the connection ID is empty, and the number of the demon slave VI connection resets to 0. When communication is re-established between the PC and PLC (like 10 seconds after the closure of the dialog box), the number of connection go to 1 and table of login ID is no longer empty.

  Otherwise, the communication works very well. But not when the dialog box opens and is a significant problem for me because the user must be able to open results file during production that needs the Modbus communication at work because it's the controller who gives orders the computer to run the production cycle.

  Thanks in advance for your help.

  If you think that the problem is inside the library NI Modbus (old), why don't you use the most recent which is available on the network of tools? Link is here: https://decibel.ni.com/content/docs/DOC-30140

  Looking into some of the screws in the library, she uses methods of Server VI as "Run a VI" that will perform the loop of the root, as it crashes while the file dialog is open. I suspect that the new version of the library is not the problem.

• Interface MODBUS master/slave... need DSC & OPC?

  I read up on top of the DSC & OPC modules looking at reasons why I would or would not need these modules for my particular application.

  I have a custom designed PLC I need to communicate with.  We look at the advantages/disadvantages with regard to the use of MODBUS ethernet communication to send control commands & reception around a number of 100 channels input data (1 to 2 times per second).   LabVIEW on Windows system is the master device and the seat PLC as the slave device.  Will we have the DSC or OPC modules?  We seek to create our custom MODBUS code.  Is here, that make the DSC & OPC modules really do?  More of a plug-and-play option for customers do not have to develop a custom code?  Develop a code custom this broad?  It seems that I could with just the drivers MODBUS provided through LV... but would like to hear your comments on that.

  Also, the MODBUS ethernet is quite easy to configure on the deployed applications (desktop / laptop)?  Currently, we use an IO CAN for connection & this works pretty well and is easy to install and deploy... but is a bit expensive.

  Thank you

  Hello

  The main advantage of the DSC module is that it allows you to use variables shared in the form of tags to connect on multiple protocols (such as MODBUS or OPC) industry, which eliminates a lot of hassle with the side of things communication. In addition, it allows the log all your variables to a relational database, as well as alarms and events with a minimum of difficulty. I won't get in the list of full features here, but if you're interested, you can learn more about DSC Module information page.

  For your application, it seems that your PLC will make communication MODBUS Ethernet, OR OPC servers shouldn't be necessary unless you really want to publish data PLC to OPC for some reason any (without programming). In addition, if you want to use OR OPC servers, you probably want to make sure that proper operation with your PLC. There is a hardware compatibility page that lists compatible devices.

  The main advantage of using DSC on the MODBUS library is ease of use and deployment. Since all your i/o MODBUS is on your shared variables, your application data sources are all managed by the LabVIEW project and can be changed centrally.

  For a quick - and dirty preview, there is a demo on the latest features DSC and demos (link to the demo) page. This particular demonstration shows how to read and write specific addresses on MODBUS Ethenet without wiring from a single piece of LabVIEW code.

  If you are looking for a cheaper alternative, the MODBUS library is definitely worth looking into. My recommendation is to try the DSC Module and the MODBUS library and see which suits you best.

  Good luck!

• How can I write the value of floats Unitronics vision230 PLC with modbus Ethernet

  How can I write the value of type Float in unitronics PLC Vision230 modbus ethernet (Ethernet Master Query.vi MB) usinsg I read and write register 32 bits, for example, I want to write the value 23.45 2nd Add. MF. And registry MF is the 32-bit registry. I read and write register 32-bit.

  Narendra.

  Narendra,

  Two characters can type cast into a uint16 you VI supports.

  To summarize. Take one (4 bytes). Flatten it to a string (4-byte) divided this string into two parts of 2 bytes each. Cast in u16 (16 x 2 = 32-bit).

  However, if you really want to follow the IEEE standards then you will need refer this KB. His is not that simple, but seems closer to what you are looking for.

• Send the ASCII string as command to device Modbus Ethernet

  Hello precious developers,.

  How send us the next command in the chain from a PC to a Modbus Ethernet device to start using LVDSC 411000 address:

  "H""$0D""$0A"

  (Function code 16 - write several operating records)

  Pointers / suggestions / code example should be deeply appreciated.

  Do you know how many records it will take?  (I'm guessing 1 registry for all 2 characters).

  String to byte array to obtain a table of ascii characters that make up the message string.  I would use decimate the table to get 2 tables 1 d of each other byte U8.  Can use numbers to join to get a table 1 d of U16.  Then, you can send this U16 table using the LVDSC module to the correct registry address for however much it records needs.

• example of Modbus ethernet

  Hello guys,.

  I use Labview Application Builder to create a program exe based on MB Ethernet example Slave.vi, but it can not communicate with MB Ethernet example Master.vi correctly, prior to construction, original slave and master example programs can communicate well, but after stabilizing MB Ethernet example Slave.vi exe program, these two don't work the way you want, is there anyone faced this problem before?  Maybe some configeration need to be addressed during construction.

  Thank you very much.

  Coolbear,

  There are a few screws called dynamically inside the NI Modbus Toolbox.

  Just include any Toolbox in your application, and everything is going to be screwed up:

• Required interface for Modbus ASCII or RTU and Labview?

  What hardware is required to interface a Modus ASCII or RTU unit to the PC that has Labview drivers?

  Thank you.

  Hi dbaechtel,

  Modbus works through each series or Ethernet, depending on the device you are using.  The only equipment you need next to the device you are trying to contact is a card series or Ethernet card, which are not in most computers.  In addition, you probably do need cables.

• Ethernet LAN identified and connected on HP pavilion M6 1002 - tx Win7 home premium 64-bit

  Model: HP pavilion m6 1002-tx

  OS: Windows 7 Home Premium 64-bit

  I bought a HP pavilion m6 1002-tx win7 Home Premium 64 - bit two weeks back. (November 30, 2012)

  I am not able to connect my ethernet lan because the system loses the connection just as I connect to the adapter. Its continually go... like... ID disconnected... identify... disconnected... and so on.

  It is a Realtek PCIe GBE family controller (Version: 7.54.309.2012). I checked the Ethernet driver lan on the hp support site and it is even installed on my system.

  Please help me solve this problem.

  Check if the connection is really good. Other laptops are able to use this ethernet cable? Try to change the speed and duplex to 10/semester, it will be useful.

• Network preferences do not offer the physical Ethernet devices I (and necessary)

  When configuring network in vmware workstation Linux 9 it offers me only a selection of devices, apparently limited by too simple string-based filtering. I offered my < n > eth named devices, more a Linux already existing bridge.

  However, the device that I need to connect is called "ethmain1", which is a physical ethernet port and the only network where my DHCP and PXE servers are listening.

  There are also way incorrect "eth0", which I do not at all. This makes the automatic setting fails because it selects eth0 that does not exist.

  Is there a text file where I can just tell him the right name?

  Allright, so the answer for later use.  Thanks a lot for the support to help with this.
