Honeywells C300 Controller provides powerful and robust process control for the Experion platform. Based on the unique and space-saving Series C form factor, the C!! "oins the C#!!, C#!!E, and the $pplication Control Environment %$CE& node in operating 'one(well)s field-proven and deterministic Control Execution Environment %CEE& software.What Is It?*deal for implementation across all industries, the C!! controller offers best-in-class process control. *t supports a wide variet( of process control situations, including continuous and batch processes and integration with smart field devices. Continuous process control is achieved through an arra( of standard functions that are built into control strategies. +he C!! controller supports the *S$ S,,.!- batch control standard and integrates sequences with field devices, including valves, pumps, sensors, and anal(.ers. +hese field devices trac/ the state of the sequences to perform pre-configured actions. +his tight integration leads to quic/er transitions between sequences, increasing the throughput.+he controller also supports advanced process control with 'one(well)s patented 0rofit 1oop algorithm as well as custom algorithm bloc/s, which let users create custom code to run in the C!! controller.How Does It Work?1i/e C#!!2C#!!E and the $CE node, the C!! operates 'one(well)s deterministic Control Execution Environment %CEE& software which executes control strategies on a constant and predictable schedule. +he CEE is loaded into the C!! memor( providing the execution platform forthe comprehensive set of automatic control, logic, data acquisition and calculation function bloc/s.
