I/O modules

Core Dual-Role PROFIBUS Network Interface

The Woodward SST-PB3-CLX is a versatile PROFIBUS scanner module for ControlLogix systems. This module functions simultaneously as both a master and a slave device on the PROFIBUS DP network. It enables long-distance communication between a ControlLogix processor and remote I/O devices via PROFIBUS. Consequently, it serves as a critical gateway for integrating distributed fieldbus architecture into the Rockwell Automation ecosystem.

High-Speed Communication and Flexible Installation

This scanner supports the full range of standard PROFIBUS baud rates from 9,600 up to 12 Mbaud. It can establish one output connection and up to 15 listen-only connections for flexible network configuration. The SST-PB3-CLX installs in any available slot of a local or remote 1756 ControlLogix chassis. Furthermore, its asynchronous operating mode ensures reliable data exchange with various PROFIBUS DP devices.

Detailed Technical Specifications

Designed by Woodward, this module is compatible with Honeywell PlantScape and Allen-Bradley systems. It is configured using the dedicated SST PROFIBUS configuration tool for setup and data mapping. The following table details its key network, performance, and compatibility parameters.

Application in Distributed Control Systems

Use this module to connect a ControlLogix PLC to a network of remote PROFIBUS DP I/O drops, drives, or analyzers. It is ideal for applications requiring long-distance device integration beyond the reach of native ControlLogix networks. The Woodward SST-PB3-CLX effectively bridges the gap between Rockwell and PROFIBUS device ecosystems. Therefore, it is a strategic component for system integrators building hybrid control architectures in manufacturing and process plants.
