ABSTRACT:
A distributed control system for local or remote control of equipment. The distributed control system provides a communication bridge through a local control panel between a non-real-time network, and a real-time network, such as a controller area network. Both soft real-time and hard real-time networks are suitable, but hard real-time is preferred. Multiple distributed control units are used to control various equipment components. The distributed control system may be applied in any environment. The distributed control system may be applied to a skid-mounted coiled tubing unit.
