YOKOGAWA FCN-FCJ Logic Designer by YOKOGAWA Electric Corp. is a professional engineering environment for configuring and programming STARDOM FCN and FCJ autonomous controllers. It streamlines the entire lifecycle of control applications—design, test, deployment, and maintenance—for distributed and edge automation.
The software supports IEC 61131-3 programming languages, including Function Block Diagram, Ladder Diagram, Structured Text, and Sequential Function Chart, and provides reusable function block libraries to accelerate development. Engineers can define I/O assignments and task execution, build modular strategies, and simulate logic before downloading to controllers. Built-in tools enable online monitoring, forcing, and step-by-step debugging, as well as safe online modifications to minimize downtime.
Project comparison, documentation generation, and secure download/upload help maintain consistency and traceability across sites. Designed for robust operation in networked environments, FCN-FCJ Logic Designer works seamlessly within Yokogawa’s STARDOM architecture and supports scalable control solutions for process industries, utilities, and remote assets.
