Yes it could. Many VR's have adjustments for limiting excitation to a level suitable to the application. A resistor is sometimes used in series with the field to limit current. We use speed switches on some applications to turn the VR off below a set RPM. The bottom line is that the VR should be...

This is for Shotgunner. You could set up a DH485 Network. This is easier than it sounds. Simply add an 1746-NET-AIC(Advanced Interface Converter) at the PLC and another at the PanelView. Conect them with the appropriate communication cabling, and you will be able to access the PLC from either...
