• connect LabVIEW to PLC

  Hello

  I try to connect LabVIEW to controller using an OPC server of NOR. Its a controller logix (Allen Bradley) L23E Compact and I find it difficult to obtain the device driver. Please help me with this topic and a link explaining how it would be useful to connect labVIEW to PLC.

  Thanks in advance,

  Sunil

  Hi Sunil,

  
  

  Regarding the driver:  See the taken list supported device & driver plug-in for NOR-OPC Server

  Regard to the connection in LabVIEW:  You have two main options that depend on the question of whether or not you have the LabVIEW DSC Module.  As seen here, you can either use variables shared with DSC to access your OPC tags, or you can simply use DataSocket VIs contact them directly as an OPC client.  Some documents that may be useful by adding your specific hardware can be found here and here.

  I hope this helps!

• How to connect Labview to PLC Modicon Quantum (140 CPU 311 10) with Modbus

  I was wondering if someone could give some tips on how to connect Labview to Modicon Quantum plc (the card is 140 CPU 10 311).  I am eager to serve a Labview HMI to control the controller that is used to implement the control PID with a VFD.  Currently I can communicate via Modbus to the API for programming using UnityPro XL, but I have no idea how to connect Labview.  I read the article on place OR "connect Labview to any PLC via Modbus", but I don't know yet.  Any help will be greatly appreciated.

  Hey Greener.

  Communicate with the PLC via Modbus usually requires the Datalogging and Supervisory Control (DSC) Module to have this feature available in LabVIEW. The white paper which indicated you using this module, which may explain why you can't get the communication at work. If this is something you don't have, and purchasing a license is not an option, then you might be able to use Modbus unofficial libraries to get the functionality you need. I have included a link below to a Modbus for LabVIEW library that you can try.

  DSC module:

• Oscillations in the logic controller output blurred

  Hello

  I recently implemented Fuzzy Logic Controller in Labview 8 for the control of a wide process station. I used Compact Point of field (PDC AIO 110) for it to interface with the hardware. Here are some other details

  Entries to FLC: error, derived from the error of the Signal of the level transmitter

  Fuzzification: Max - Min

  Defuzzification: Center of gravity

  Level sensor: capacitive Type level transmitter

  FCE: Control valve

  Data acquisition: cFP2020, PSC AIO110

  Then, when I run the VI... I am able to control the water level in the tank successfully, but there are oscillations in fuzzy logic controller output. The oscillations are so intense and change very adbruptly. I need to fix this oscillations, as this may damage the equipment.

  I am in need of a solution that makes the controller smooth response... Any suggestions? I need to solve this problem as soon as possible, as the deadline for my project work acad is almost

  PS: I do not know if this post is in the right section, if not please move to the appropriate section. Please let me know I'f I need to provide any additional information

  Thanks in advance

  When you do the (k) e - e(k-1), it's an implementation of the oblique action, actually. You can implement by mistake or by using y (k) - (k-1) there also. This would avoid the effect of set point, when you change the target value, it is a mistake that is used by the derived variable.

  To better describe what I mean, please open the example:

  C:\Program Files (x 86) \National Instruments\LabVIEW 7.1\examples\control\fuzzy\tanks.llb\Tanks - control blur PI.vi

  and try to see the screenshots below:

  1 change the boundaries of your function of members associated with the derivative action will make the answer less susceptive to noise. This is where you should focus on the Fuzzy Editor.

  

  2. the filter function is called: PID control entry Filter.vi and this implements a 5th order FIR filter. If you want more on the filtering option, you would have to use the LabVIEW functions for parsing > Signal Processing > filters. Here's how you should use the FIR filter:

  

  3. the speed limiter is called PID output VI rate limit and it is used as:

  

  These are the options that I was discussing.

• Connect labview with proteus

  How to connect labview to proteus in order to send commands to the microcontroller AVR, there a useful link or source code?
  I've heard talk about VISA can you help me with a code example or source?

  I don't know anything specific to the APR, but Finder of LabVIEW example has many examples on the realization of serial communication ("Help-> Find examples.." then look for series). If you know the Protocol, then you can use the samples to create right necessary read and write commands.

  Also a quick search on Google for 'Labview APR' had this as the top most successful:

  Hello

  -Do you have Bluetooth devices internal or external connected to the laptop?
  -Have you checked if all the Bluetooth drivers on two laptops are very well installed?
  -This work was fine before? If so, what are the hardware/software changes made on the computer before this problem started?
  -Is a problem only when these 2 laptops connecting or is that when you try to connect these 2 laptops at any other laptop too?

  I suggest you to go through these below items that could help you to fix this problem.

• Problem of password of account, without that we can connect to the network on this computer. The error indicates, "the trust relationship between this device and the network is no longer valid.

  Hi, I hope you can help with this problem. A friend has 6 computers networked to a Tower Server and have a problem. A worker student put computers into hibernation, and since then, nobody can connect to the network on this computer. The error indicates, "the trust relationship between this device and the network is no longer valid. I tried to get into the pc to try removing network and replace it, but I can't get on the Administrators account because it has been disabled. I'm at a loss on how to proceed. My friend cannot afford a service call, so I'll try to help him.  Thank you

  If the computer is on a domain then there are at least two accounts that can be used to remove the computer from the domain:

  • A domain administrator account.
  • A local administrator account.

  When your friend has launched Windows for the first time after buying the machine, he was prompted to enter the name of an account. This account is created automatically with administrator privileges. He should use it now.

  Dear all,

  My11gR2 database on windows 2008 R2 Standard is in error "ORA-28547: connection to the server failed, probable Oracle Net admin error.

  It's when I try to log on to the server itself

  But even if it doesn't in my case.

  Guys, there are 2 databases installed on the same server, to correctly configure the SID. Once set, I could see that the database is down and when starting it started working well.

• Connect LabVIEW with a via USB pic 18f4550

  Hello everyone, as the title suggests, I would like to have communication with the PHOTO above, in order to to use as a sort of buffer control. Nothing complicated or fancy, I would use it as a sort of buffer, with LV, do all the calculations and lifting heavy objects, while the PEAK only manages communication and nothing else. Specifications are:

  -I would like to order 2 Motors step by step, I already have the drivers who are driving binary pulses (1 pulse = 1 step)

  -May or may not require an analog (0 - 5V) encoder feedback, so for now, let's assume that Yes

  -As mentioned, nothing complicated like PID or advanced control in the PIC, just send and receive some movement, LV will do most of the work as it's the only one I'm more familiar with

  -I am well informed, but not particularly good in programming C (not my cup of tea), but I'm pretty adept at BASIC, my particular environment is PIC Simulator IDE of Oshonsoft and his recent iteration, the Basic compiler.

  I've done a substantial amount of research, but most of the info is pretty obsolete, and most of the download links no longer work. I know I should use General dll of Microchip (already had), but would like to know if someone has done something similar, or could give me a starting point. I also read the white paper found here: http://www.ni.com/tutorial/4478/en/#

  So basically, if anyone has the tracks on a good starting point, tutorials, I have to take or bases miss me, they would be welcome. Thanks to a bouquet.

  I think it would be simpiler using a virtual COM port device such as the ones FTDI

  Then schedule a connection series on your PIC and just use VISA in LabVIEW to communicate with the captain like communicating with any other serial device.
