Leadfoot, appreciate your feedback, as well as others. To answer your last question, I'm not sure...I don't know what control model to use yet.....I need to ponder this for a few days. I'm kinda trying to decide weather or not to leave the control up the the VFD's, I'm using ABB ACS550's or run the control out of the PLC were're integrating....A PLC really wouldn't be required, but we're integrating an HMI with it also, so they can have visualization as to what's happening downstream...
