Powerflex 755 Communication

Hello all,

 

I am a mechanincal engineering student at Milwaukee School of Engineering.  I am building up a dyno system to test small engines.  We are going to do our data aquisition and control with LabView.  Our dyno is a 20 HP electric motor coupled to an Allen Bradely Powerflex 755 motor drive. 

 

How can we establish communication between the drive and LabView?  The drive communicates using either Allen Bradely's Eithernet/IP Protocal, rs-232, ect, or analog inputs and outputs.  Ideally we would use the eithernet connection.  Has anybody written any LabView code to comunicate with Eithernet/IP?  If not where should we start? 

 

Thanks in advance for your help!

You can use VISA to read and write to your device over Ethernet.

Can you see your device in MAX?

 

Have you read this?

OK. So far I have been able to successfully "ping" the motor drive. 

 

I am having trouble creating a new device.  When I go to create a new device the only option in the wizzard I have to choose from is "Devices and Interfaces"

Could there be a module that i am missing or some kind of software error that is preventing me from being able to successfully create this VISA device?

In MAX, do you not see the "Create New..." options from a right clik on "Device and Interfaces" or the "Create New..." button at the top?

Yes.  I see create new, I click it, and the next dialog box doesn't seem to be working.

Can you post a PNG of the dialog box that doesn't seem to be working?

 

Something like this?CreateNew2.png

Good idea.  We are updating some of the software. If that doesn't fix the problem, I'll post a picture tomorrow.

 

Thanks again.  I appreciate the help.

 

I like this forum.  I get a kick out of the fact that the newbie's icon is a car with a really big spoiler.

I was able to create a VISA TCP/IP resource for the Powerflex.  It doen't seem like its working though.  When I click "open VISA test pannel"  I get this error message:

Any idea what might cause this?
