Honeywell FC-SCNT02 Field Control Scanner Module

The Honeywell FC-SCNT02 is a next-generation field control scanner module engineered to expand the connectivity of Experion PKS controllers to remote I/O and field devices via Profibus DP and other industrial protocols. Building on the success of the FC-SCNT01, this module adds native Profibus DP master capability, making it ideal for integrating drives, motor control centers, and third-party I/O systems into a unified DCS architecture.

Key Features

• Profibus DP Master: Directly connects to Profibus DP slave devices such as Siemens ET200, drives, and valve positioners, supporting baud rates up to 12 Mbps.

• Multi-Network Support: Additionally supports Modbus RTU/TCP and ControlNet, providing backward compatibility and flexibility.

• High-Speed Data Exchange: Optimized for real-time control with deterministic scanning and low latency.

• Redundancy and Hot-Swap: Supports redundant module configurations and can be replaced without system shutdown.

• Advanced Diagnostics: Detailed network statistics, device status monitoring, and fault logging via Experion PKS.

Technical Specifications

• Communication Ports: 1x Profibus DP (DB9), 1x Ethernet (Modbus TCP/ControlNet over IP), 1x RS-485 serial

Applications

The FC-SCNT02 is particularly valuable in industries where Profibus DP is prevalent, such as automotive, material handling, and water/wastewater treatment. In process industries, it integrates Profibus-based analyzers, smart motor controllers, and remote I/O racks into the Experion PKS environment. It also serves as a gateway for legacy systems, enabling gradual migration to a unified automation platform.

Configuration and Integration

Configuration is performed via Honeywell’s Control Builder, with intuitive wizards for Profibus DP network setup, slave device parameterization, and GSD file import. The module’s data is automatically mapped into the controller’s tag database, simplifying engineering. Real-time diagnostics are accessible through Experion’s asset management tools, allowing predictive maintenance and rapid troubleshooting.

Reliability and Environmental Performance

Built to the highest industrial standards, the FC-SCNT02 operates reliably in extreme temperatures, vibration, and electrically noisy environments. It features galvanic isolation on communication ports and complies with international EMC and safety directives. Honeywell’s rigorous testing ensures long service life and minimal downtime.

With its enhanced Profibus DP capability and robust design, the Honeywell FC-SCNT02 field control scanner module empowers plants to achieve seamless integration and real-time visibility across diverse automation assets.
