Integrated Production Control System

CENTUM CS 3000 R3

Control Features

In addition to the regulatory control and sequence control blocks that form the basis of control functions, superior sequence control blocks such as unit instrument and Sequential Function Chart (SFC) blocks are provided. More than 200 types of function block are provided to satisfy the requirements for various process control applications in continuous and batch process control systems.

Regulatory Control Blocks

Regulatory Control Blocks perform computations based on process values for process monitoring and control, and include PID controllers, input indicators, manual loaders, signal selectors, signal setters, and self-tuning controllers.

Sequence Control Blocks

Sequence control blocks are used to implement general-purpose sequences at the loop equipment level, such as safety interlock sequences and process monitoring sequences. The blocks are coded in decision table format and logic chart format using logical operators. Switch instrument, timer, counter, code input/output, and various other blocks are prepared as sequence auxiliary blocks.

Calculation Blocks

Calculation blocks assist regulatory and sequence control functions, and perform general-purpose calculations on analog signals and contact (logic) signals.
