DISTRIBUTED CONTROL SYSTEM |
摘要 |
A method for distributed control of a coiled tubing unit and an associated distributed control system. 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 and hard real-time networks are suitable, but hard real-time is preferred.
