does someone have a driver for kloehn pumps

[mtngirl]

I would like to control a Kloehn syringe pump with Labview 7.0 via a DAQCard. Has anyone written a driver for these pumps that you would be willing to share?

Hi mtngirl,

I've searched through our Instrument Driver Network, Kloehn's website, and Google for any driver for a Kloehn syringe pump without success. I was able to find a book on Amazon.com, "Practical Pharmaceutical Laboratory Automation", that has commands that you can use to control a Kloehn device (listed in the index), but I'm not sure if you have it already or not.

Also, I read through the "Pumps" page of the information on Kloehn's website, and it says the "V6 Module is a full featured, ready-to-use syringe pump with extra built-in capabilities. Simply add a 24 VDC power source and a control command logic (via RS485 or RS232) and this module is ready to perform." I'm not sure if this is true for all Kloehn pumps, but as it takes commands via RS485 or RS232, you will more than likely need to control your device with a serial cable, rather than a DAQCard.

In any case, it looks like your best bet from this point is going to be to request a driver, if you haven't already. You can do this by going to the Instrument Driver Network, and following the link to "Request Drivers". Hopefully this helps you on your way. Good luck!

I have recently incorporated a Kloehn V6 pump into a system using RS-232. So, if you purchased the serial interface I'm willing to share an unapproved serial driver that I built.

There are a three purchase options for the V6, in terms of control:

1) stepper motors
2) stepper motors & motor drives
3) stepper motors & motor drives & serial control

Which option are you working with?
If you have the 3rd, what I have to offer will work.
If you have the 2nd, a DAQ board ought to work via a step and direction digital output scenario.
If you have the 1st, a DAQ board ought to work provided the system already has motor drives.

I do have the serial interface, and I would like to try your driver. Thank you for being willing to share. You can email it to me if it is not too large (I think 1 MB). Otherwise, you can post it to: ftp://ftp.umt.edu/pub/incoming/rspaulding/

Thank you again.

Hey!
Sorry for the delay. Holidays...
Anyway, I put a LabVIEW 7.1 llb file on the ftp site. Good Luck.

Dear SlpiKnot: Thank you for the driver. Can you give me instructions on how to install it.

[SlipKnot]

There isn't really anything to formally install. With the LabVIEW IDE, open the LLB's only top level VI 'V6-Utility.vi' and if you wish run it (assuming you are cabled to the pump). The library contains the 'V6-Utlity.vi' as a sample application wherein all of the pumps capabilities have been implemented in the underlying LabVIEW code. Think of this as a pump interfacing program for which you have all the LabVIEW source code. I'd suggest perusing the 'V6-Utility.vi' code to see how it is built perhaps with the V6 command documentation in hand.

Hope that helps.

Hello mtngirl, Slipknot,
   I just found this dicussion thread today, and I am trying to accomplish the same thing: writing labview code to control a Kloehn V6 syringe pump.  I've had some limited success to date, so would love to see some code to build off of/use.  Can either of you post the code, or perhaps send me a copy via e-mail?  It would be a big help!

Thanks,
NormalAndrew

Hello,

I am also interested to get drivers for the Kloehn pumps. I will really appreciate if you could e-mail me a copy?

Thank you for advance, awaiting to hear from you,

Regards.
