Description

The SST SST-PFB-CLX is a high-performance PROFIBUS DP Master communication module engineered by Schweitzer Engineering Laboratories (SEL) for Rockwell Automation ControlLogix systems. Designed for mission-critical industrial automation, this module enables seamless integration between ControlLogix PLCs and PROFIBUS DP-V1/V2 slave devices (drives, I/O, sensors) across demanding environments like power substations, mining, and oil & gas facilities. Operating as an independent coprocessor within the ControlLogix chassis, the SST-PFB-CLX offloads protocol translation from the main CPU, ensuring deterministic data exchange with cycle times ≤1 ms. Its ruggedized design features dual-port isolation (2,500 VAC), ±15 kV surge protection, and an extended operating temperature range (-40°C to +85°C), making it ideal for electrically noisy or harsh installations.

Main Features and Advantages

Deterministic performance: FPGA-based processing achieves ≤1 ms cycle times for synchronized motion control. Dual ports support redundant ring topologies or segmented networks, minimizing cabling costs.

Substation-grade robustness: Conformal coating (IPC-CC-830B) protects against humidity, dust, and corrosive gases. Surge immunity meets ANSI/IEEE C37.90.1 (±4 kV), critical for high-voltage environments.

Engineering efficiency: Automatic GSD file import via SEL’s AcSELerator Architect software. SIL 2 capable for safety applications. Preconfigured Add-On Profiles (AOP) for Studio 5000 reduce commissioning time by 50%.

Application Field

The SST SST-PFB-CLX bridges ControlLogix with PROFIBUS networks in:

 

Power Substations: Controls breaker position monitoring and capacitor bank switches.

 

Mining: Synchronizes conveyor drives (e.g., Siemens SIMOCODE) in dust-heavy environments.

 

Oil & Gas: Interfaces SIL 2-rated pressure transmitters in offshore safety systems.

 

Water Treatment: Integrates pump VFDs with PlantPAx SCADA.
