MKS Mass flow controller PROFIBUS

[Rutx]

Dear all,

I'm a new profibus user and I have a few questions about comunications between one pci profibus comsoft card + a MKS mass flow controller.

The comunication is done, and now I need to read or write parameters to the MFC and in this step I'm blocked. On the MFC manual there are parameters like the attached picture, but I don't know in what format the parameters should be send across de profibus.

For example if I want to put a Flow_setpoint, I'm lost on the procedure to do this because exist an add., an Name, an type...I don't know if I need to send only bytes or if I need to sent directly an string of characters.

If anyone of you can help me I will be gratefull.
Thanks in advance,

Roger

Hi Roger,
You can build byte array from input data cluster to send data to MFC.
As you need, you should able to build each function block for your needs.
i.e. Send Flow Setpoint or Perform Auto Zero; ect..

Hope it helps!
