Control Logic Modeling

CtrlBuilder™

CtrlBuilder is a high-fidelity control logic simulation platform that delivers both engineering efficiency and accuracy. Using a graphical modeling approach based on predefined logic blocks, it enables intuitive design of complex control networks and supports rapid verification and simulation through an integrated testing environment.

CtrlBuilder™

CtrlBuilder™ is a professional tool designed to enable modular, graphical design and simulation of a wide range of plant control systems, including automatic control, computational logic, interlocks, sequences, and safety systems (ESFAS).

It supports the entire workflow—from model configuration and testing to validation and real-time execution—within a single environment, and integrates with the unified execution engine (MPSPexec) shared with other builders to comprehensively analyze real-time system responses.

Key Messages

Intuitive Logic Modeling Environment

– Rapid configuration using a drag-and-drop–based icon library.
– Provides a wide range of blocks, including logic operations, comparators, time-series elements, and timers.
– Enables hierarchical design of complex control structures.
– Supports user-defined icons and template storage (Custom GUI support).

Validated Testing and Execution Functions

– Built-in test mode: logic execution, condition validation, and signal flow monitoring.
– Supports Self-Test, Interactive Simulation, and Real-Time Execution.
– Detects issues in advance during testing and simulates responses to operating conditions in real time.

Object-Oriented, Reusable Architecture

– Improves reusability and maintainability by objectifying individual logic units.
– Enables block-level version control and parallel development even for complex plant logic.
– Template-based design → standardization across plants of the same type.

Flexible User Customization and Configuration

– Supports multiple GUI skins, such as aquaSkin and xpskin.
– Allows individual engineers to customize their working environment.
– Planned support for multilingual and multi-user environments.
