Communication, protection and diagnostics for cement power systems

Recent technological advancements have produced intelligent final control devices. These devices communicate operating and diagnostic information along dedicated networks to the distributed computer control system that is used for process control. This level of integration is described, and the many benefits are investigated in greater detail. The integral communications provide device status and diagnostic information, a simple twisted pair connection to a distributed control systems (DCS) I/O interface. The DCS collects this information for monitoring the overall electrical distribution system status centrally but also uses it in conjunction with other process plant information to allow the process to be operated in an optimum way.<>
