Abstract
A method of managing fluid supply in a process control system is provided. The method includes identifying, via a controller of a pilot device, a predetermined minimum source pressure, the predetermined minimum source pressure being the minimum pressure required at a fluid supply source to permit a simultaneous operation of all of a plurality of process lines. The method also includes determining, via the controller, whether a pressure of the fluid supply source is less than the predetermined minimum source pressure. The method further includes determining, via the controller, that the fluid supply source is to be changed when the pressure of the fluid supply source is less than the predetermined minimum source pressure.
