Need to install LabWindows/CVI PID Control Toolkit (Part Number 320794A-01)

Hello -
I have a customer with a very old application who needs to upgrade their system to Win7 64-bit. The app references the old PID functions (manual here: http://www.ni.com/pdf/manuals/320794a.pdf) but no matter what I have searched for, I cannot find an installation for that toolkit. I have never had a need to use the current PID toolkit so I am not versed with it, and the difference in the functions do not seem to be a 1 to 1 change. Additionally, the customer is not paying for a code change - just assistance with the upgrade and reinstall. I would greatly appreciate if someone could point me to that download.
If such a download is not in existence any longer, I will need to request some assistance with modifying the source to use the current PID functions. I could attach the pertinent code if need be (there are not a great deal of references).
Thank you.

Hi CVIBri,
The installation files for the LabWindows/CVI PID Control Toolkit 2.1 are located at the URL below. I realize these are only officially compatible with versions of Windows up to Vista, however this is the most recent version of the toolkit that exists. I've also provided a link to the Evaluation License Files. That being said, LabWindows/CVI 2013 SP2 now includes the PID Control Toolkit as part of its Base and Full versions, and it is fully licensed with the same serial number used to activate the LabWindows/CVI development environement. The Readme linked below should provide more information.

Mysql database connection with Labwindows/CVI 2009 sql toolkit

Dear experienced users,
I am using the following software/hardware:
Windows 7/ Mysql database 5.6.15 64-bit with MySql ODBC 5.2 Ansi driver installed
Labwindows/CVI 2009 with sql toolkit
The user DSN of ODBC Data source administrator have been confiugred to one of mysql database. The test MYSQL Connector/ODBC is succesful.
The Labwindows/CVI build setting is configure to debug64 after trying debug (32)
The source code is from the example readtab.c with changes to the dsn I am testing
hdbc = DBConnect ("DSN=dvd_collection");
The error message I have is confusing me.
(it is in the attachd png)
I thought it was due to the 64 bit mysql database. That's why I tried the 64 bit build from Labwiondws/CVI. I alsow tried Labview DB tools open connect.vi. It shows me the same error.
Any suggestion is appreciated.
Thanks,
Jimmy

I always use connection strings of the form "DSN=datasourcename;UID=database_user_id; PWD=database_user_password".
Where:
datasourcename = The name of the connection defined in the ODBC connection.
database_user_id = One of the user identities created by the database administrator. Obviously the administrator will lock down the permissions appropriate to the task in hand.
database_user_password = The password that identifies database_user_id, again set by the database administrator.
Note that while it is obviously desireable to lock the permissions down as far as possible on the MySQL server, the more you do so, the slower the database will run, because of the way mySQL searches the permissions tables.

Output of LabView PID Control Toolkit

I am evaluating LabView to tune a PID loop. From the datasheet, it looks like all of the analysis tools are there.
I am not clear on the output. Does it have a synthesis feature to create C code? Or is it just a matter of plugging the tuning coefficients into an existing library.
I ultimately want to port this to an ARM control module.

I'm not sure I understand what it is you actually want to do, but LabVIEW is not an analysis tool. It's a programming environment which happens to be geared towards analysis, so it has a lot of analysis tools shipping with it.
LabVIEW has an add-on control toolkit, which includes some PID functions, but those are written in the language itself and I assume you can find similar libraries for other languages as well. It will not generate C code - the LabVIEW code is compiled to machine code and is then run using a run-time engine on targets which have support for the run-time.
LabVIEW does have a couple of modules which translate the code to C. One creates the C code so that it can be run on Windows Mobile devices, but it doesn't give you access to the code. The other is quite expensive and is targeted at embedded targets. I'm not sure, but I think you do get the C code resulting from that one. Being automatically generated code, though, I assume it's not very usable.
If you have a background in C, you should probably use it. I believe eVC is available freely from Microsoft and I believe it should compile to ARM processors. That said, you can also download LabVIEW and run it for 30 days in evaluation mode.

LabWindows CVI and SQL Toolkit cursor/schema error

We are using CVI 8.5 and SQL Toolkit 2.0.6 to write data to a SQL Server 2008 database. We are utilizing the Microsoft ODBC SQL Server (non-native) driver. We build a transaction that calls stored procedures on the database to write the data. Occasionally we get the following error:
"Could not complete cursor operation because the table schema changed after the cursor was declared"
The error is unusual since we only use one cursor and it is in a stored procedure that gets called by other software hundreds of times a day and never fails. Our database is also designed to only append records, not change existing ones. We're trying to pinpoint the error and I'm wondering if anyone knows if the SQL Toolkit uses cursors to build transactions or if this error has been seen by others. Since upgrading the toolkit or drivers takes a lot of effort, I want to make sure that I understand the problem before I start throwing darts at it. Thanks in advance for any insight.

I've attached the function that's failing. Unfortunately, the code isn't designed with much resolution as to what SQL toolkit call failed, since these calls haven't failed once validated and put into the production environment. Can you tell if any of these functions use a cursor. I could certainly try adding more resolution to the error handling, but since we've only seen errors occasionally in the production environment, I'd need to release a temp version and monitor it. Let me know what you think. Thanks.

Error installing LabWindows/CVI Trial

I got the following error while installing the trial version. Any siggestions?
Thanks!
Solved!
Go to Solution.

Hi Vladiator,
1) What happens if you click "Yes" to continue? Does the installation finish? If so, does CVI work? If not, are there additional errors given?
2) Do the specifications listed in the error match the specifications of your system?
3) I realize this is related to the previous question but specifically: is your processor architecture 32 or 64 bit?
4) What operating system are you using?
The error itself seems to be linked to corrupt system files, which is really a Windows error. The error description can be found here:
Hresult: 0x800736b3
http://www.pcmmc.com/hresult-0x800736b3.php
One thing you can try is executing the "sfc /scannow" command in an elevated command prompt. This will check your file system and fix some common errors. Instructions on how to do this can be found below:
Use the System File Checker tool to repair missing or corrupted system files
https://support.microsoft.com/en-us/kb/929833
There are several other websites offering solutions to this error. However, the ones I have been able to find are all third-party and fall under the "use at your own risk" category.

Toolkit for feedback system? Motion; PID; Control/Simulation???

Hi, I have to develop/program an organ bath system - a feedback system mimicking real sinusoidal breathing oscillations (shown in attached images). I have NI Labview 8.5, NI-Motion 7.6, a linear motor (M-235 DC-Mike actuator), an MID-7654 Servo Power Motor Drive and a pressure transducer. I believe I will need to control the PID controller and am aware of the PID Control Toolkit as well as the Control Design and Simulation Toolkit for NI Labview. However, is it possible to control the system using the NI-Motion software I have at the moment? If not, do I have to purchase both the PID and Control/Simulation Toolkit or just one? Thanks in advance...

Dear Garry,
Do you have a motion controller to interface the MID-7654 to your
computer and LabVIEW? This would be the PCI-734x or PCI-735x. If you
do, I believe that you could implement your application with LabVIEW
and NI-Motion. You could do so by using the analog feedback feature for
the control loops for each axis. Then, you could specify the optimal
sinusoidal moves/pressure patterns that mimic real breathing patterns.
The analog feedback from your pressure transducer will be used during
the move(s) to maintain the pressure that you want.
Please see Chapter 13 here for more details:
NI-Motion User Manual
http://www.ni.com/pdf/manuals/371242c.pdf
Here is also a good discussion forum post on Analog feedback:
Can i use NI-7358 to implement a hybrid position force/torque control system?
http://forums.ni.com/ni/board/message?board.id=240&thread.id=2976&view=by_date_ascending&page=1
I believe that the above option would work for you, and you would not
have to use the Control Design and Simulation Module or the PID
Toolkit. Please let me know if you have any additional questions. I
haven't actually set up a system with analog feedback from a pressure
transducer before, but I believe that the above would be a very viable
option.

Hello,
I don't really understand the issue... you said that you have no problem when you install LabWindows CVI 2009 on Windows 7 - that's good!
And now you have an issue with an installation... with another software (I guess) ?
This error appears when you are installing an incompatible version or your toolkit/drivers/software with your actual OS.
As you are using Win 7, I suggest you to check the compatibility of what you want to install on your computer : http://www.ni.com/white-paper/10383/en

Visual Studio or LabWindows/CVI?

I have a bit of a dilemma.
I currently own Visual Studio 2010, IMAQ Vision Development Module 2013, and Measurement Studio (not sure of version). I currently do all of my programming in VB.net. Because IMAQ VDM is stuck in .Net framework 3.5 and there will be no further .net development by NI, I need to plan for the future. My applications need run on Win 8, 9, 43, or whatever my company decides to migrate to from Win 7.
My understanding is that the NI modules I currently own will work with LabWindows/CVI. Correct? I also believe I can use them with C++ using the VS IDE. Is this also correct?
Within my applications I do a lot of interfacing with Excel, writing text files, and interfacing to non-NI devices (cameras, DAQs, scanners, etc). I am able to do these things pretty easily using VB.net using vendor-provided SDK's.
Therefore, my question is this...given the investment I have in software already, do I gain anything by migrating to LabWindows/CVI? What do I lose?
I should point out that regardless of the path I choose I will need to bone up on my programming skills in the corresponding language.
Thanks for all your help!

Hello Steverino!
Here are some advantages when using LabWindows/CVI over Visual Studio, which make the product more suitable for various industry-related applications:
You are correct, LabWindows/CVI integrates with the NI platform: NI hardware and software, like TestStand or LabVIEW (e.g. debugging source code from one software to another, seamlessly).
NI hardware and third-party hardware connectivity.
OpenMP support.
CVI integrates with intrument control.
CVI Run-Time benefits from User Protection.
Run-Time checking (e.g. for uninitialized variables).
Scientific User Interface Controls and GUI Editor.
Advanced debugging capabilities:
Remote debugging support from ADE.
Real-Time debugging support from ADE.
Memory leak detection using the LabWindows/CVI Resource Tracking Window.
Just-In-Time debugging.
Deployment: build custom installers and patches that you can ship as stand-alone easy-to-use installers.
LabWindows/CVI libraries: Advanced Analysis, Toolbox, Connectivity (Network Variables, Network Streams, DataSocket), etc.
Support for LabWindows/CVI Toolkits: SQL Toolkit, Vision, PID, RT.
Regards,
- Johannes.

LabWindows/CVI 2009 Run-Time Engine update

I wanted to let everyone know that NI has released an udpated CVI 2009 Run-Time Engine. Information on what bug(s) this update fixes can be found here. If you are currently not using the CVI 2009 Run-Time Engine, you do not need to install this update.
This is an updated installation of the CVI Run-Time Engine, not a patch. If you download and install this update it will upgrade whichever version of the CVI Run-Time Engine you currently have to version 9.1.0.428 (CVI 2009 released with version 9.1.0.427). One way to find out which version of the CVI Run-Time Engine you have installed is to view the version number of c:\windows\system32\cvirte.dll. If you install version 9.1.0.428, any installer distributions that you create from any version of the CVI ADE will include version 9.1.0.428.
If you have not yet installed LabWindows/CVI 2009, it's recommended that you install this update, either before or after you install CVI 2009.
Luis

To be clear, the original problem that you reported ("Attempt to free pointer to memory not allocated by malloc() or calloc()") might very have been the problem that this patch fixed, which was in fact new to 2009. But that problem only happens if there were actual plots in the graph.
However, after looking at the "dynamic memory is corrupt" isse some more, it turns out that it is actually expected behavior, believe it or not. This is a limitation of easytab controls, caused by how they use callback chaining in their implementation. Whenever a panel or a control has its callback chained, you cannot change the callback, or make a copy of it after the chaining takes place. This is described in the EasyTab_ConvertFromCanvas function help ("...For the same reasons, do not call DuplicatePanel or DuplicateCtrl on any of these panels or controls after the Easy Tab control has been created.").
As you probably have read elsewhere, easytab controls are quite obsolete. They were a stopgap "solution" to the problem of there not being a native tab control in the CVI user interface library. Native tab controls were finally added in CVI 8.0, and so we recommend that, if possible, users update their code to use these instead.

PID control in a windows CE Labview application

Hi there,
I want to build an application that will control the temperature in some ovens, using PID control. The application will be running in a controller (or a touch panel computer) with windows CE OS. I have Labview 8.6, PID control toolkit 8.6 and Touch panel module 8.6. The problem is that the PID vi's don't seem to work in touch panel module.
Is there any way to implement PID control in a windows CE Labview application?
Thanks in advance.
Solved!
Go to Solution.

I think with a timed loop you can run reasonable good timing down to 1 mSecond. I think 1 mSecond is the lower limit for non realtime systems like Windows/windows CE. And if you have the PID toolkit this will supply you with the functions you need. You do not need an extra CE PID toolkit. This because the touch panel module run under your standard Labview environment. But I do not know if all the functions in the PID tool like fuzzy logic are compatible with CE. Have you also considered Windows Embedded as OS for your module. With windows Embedded you can run standard Labview built exe files
Both Windows Embedded, and XP Embedded can be trailed

Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

PID Control motor DC 12v

Hi everyone,
I wanna control a 12v DC motor using PID control toolkit 8.2.
- a close loop control system
- using a DAQ model: NI USB-6008
- how do make a DC motor speed control 12v with PID control
Im stuck at getting pid.vi and i wanted to know what is the problem.
pls help me on my problem, if can pls make an example VI for me
Thanks !
Solved!
Go to Solution.

Well there are a lot of things you need to do this, LabVIEW software being only a part. Firstly, most DAQ cards will not source sufficient current to actually power a motor, particularly a USB6008, so you will need some form of amplifier/power driver. For closed loop you will need some feedback to tell you what the motor rotation is, usually a slotted wheel with a LED and sensor (if this is a project for school or hobby one source you might look at is an old wheeled mouse). So with these two you have a way to drive the motor and then detect its motion. Then you can get to the idea of doing PID, which is taking the feedback (from whatever sensor you end up using) scaling it to match whatever you are using, and apply it to one of the PID equations to get it to match the target value.

82351a with labwindows cvi

Hello,
I am trying to use Labwindows CVI 2013 with a GPIB card, Agilent 82351a and it can't talk with a GPIB instrument connected to the GPIB card.
NI-MAX can see the 82351a card but I can't use this card to talk with an instrument.
I installed Labwindows CVI with NI-VISA 5.4, AGILENT IO suite 16.3 with Agilent Visa a secondary VISA.
With NI-MAX, in the options VISA, I enable "Passport for Tulip" and with Agilent Connexion Expert, I tried to enable '"programs Agilent GPIB cards for 488" but it reboots the PC and the option remains not validated.
I wan't to know if this Agilent 82351a card can work with Labwindows CVI 2013.
thanks

Create a NI based PID control system? Advice?

I need to make a new PID control system using labview. I have a magnetically levitated shaft, spinning at 80,000 RPM and is subject to axial loads.
It is a pretty simple. One axial input, one output to an amplifier.
I need it to be fast, dynamic and stable.
Does labview have these capabilities? I suppose I would need to scan the one input channel continiously, and be continuously writing a PID derived control signal which would need to be smooth, obviously not notchy.
What hardware has the capabilities to read and write continuously and have the speed i require. I suppose 20khz input would be fast enough.
I have a current sytem that died on me (motherboard failure) but the computer which is a 486!, the card, the software are all SUPER old, and no one knows how to use it anymore. The DSP card company has been purchased several times and is totally unsupported.
So:
What hardware do you recommend?
What software? LV + PID toolkit?
Anything else?

FPGA is a reconfigurable logic, I can describe it as a kind of "programmable hardware", in the sense that the actual chip is defined in a high level description language, which define connections between logical block of the FPGA. Of course, you can find better definitions on wikipedia, i guess....
Anyway, you don't need to care about how does it works: it matters that these devices are used in real-time, reliable acquisition.
Real-Time is expensive, but consider that you can get discounts buying NI Developer suite, possibly buy one that includes Real-Time and PID module, check your country's sales representative. In my company, we bought NI Developer suite "Control Edition", but it was about 2 years ago, nowadays, I don't know what similar product is offered by NI...
Yes, since cRIO is meant for reliable DAQ, it can do continuous sampling 24/24, 7/7. Only take care to write a reliable software in labVIEW!
Hope it helps.... have a nice day!

Steps to create vi file for PID control in 8.0 pro without specific PID addons.

Per my other posts, I am testing a friend's software to see if this is what we would like to use. I would prefer to use their software for our initial work to help offset the cost of the software. Problem is their software is 8.0 pro without the extra PID stuff. I am curious how one gets started creating a custom PID algorithm to be used in series between an input and an output. I have viewed several tutorials but all seem to simply point at the PID toolkit that is not availalbe to me right now. I realize it might be more work to create one but probably the only option at this point.
To simply the process, lets just compare a single input and output where the software will control the output to obtain to desired input. in tutorial, I was following right along until the PID loop was added and that seems to be just a drop and go type of deal in which would rarely apply to a real work application. I am simply trying to learn how PID systems are written into the block diagrams.
Hopefully my question makes sense.

Take a look at the PID Control Toolkit User Manual . It clearly defines the math used and there is absolutely nothing stoping you from writing that code yourself.
What you will not get by doing it yourself is the auto-tuning as well as all of the supporting and helper sub-VI along with the polymorphic versions that will support arrays of PIDs.
If you write it yourself and it work good please post up your version for others to review or use.
Have fun,
