Controlling a VFD with laptop PC using PROFIBUS

[jschwei314]

I am looking for a program that will turn my laptop computer into a Master to control a VFD using PROFIBUS.

I have used MODSCAN 32 to do the same thing using MODBUS. This program works great.

The idea is to test, run the VFD with PROFIBUS.

This might do it!

I would think siemens would of developed some laptop feature that you are descibing.

There are PC cards that interface to a profibus network but are not the master. Probably not interested in this I am sure.

Controlsdude,

Thanks for the link.

I am hoping for a simple program that turns my PC into a master and then using a 232 to 485 converter, control a VFD for testing purpose.

Make sure the drive works with PROFIBUS.

Yes, Siemens has a PC board / card and software that will turn your PC into a Profibus master, I will look it up and post a link later.

After much wailing and nashing of teeth, and the help of HMS

Using their Master Simulator and software I was able to control a VFD using PROFIBUS

Thanks for the come-back!

Was there some 'key' detail you could share?

Keith,

I can not complain about THE BOSS as he did spring for the money.

I work very little with PLCs. The KEY was when it came to mind, control word 47F hex is also 04 7F hex. That silly zero made 16 bits make sense.
