Overview

The WOODHEAD SST-PB3-CLX is a PROFIBUS DP Remote I/O Master Scanner Module designed for seamless integration with the Rockwell Automation ControlLogix PLC platform. It allows ControlLogix systems to act as a master on a PROFIBUS DP network, facilitating high-speed communication with third-party PROFIBUS slave devices such as remote I/O blocks, drives, and sensors.

This module eliminates the need for external gateways, simplifying integration of heterogeneous control systems while reducing cost and engineering effort. Its robust design ensures reliable operation in demanding industrial environments.

Technical Data

Typical Applications: Industrial Protocol Integration

• Automotive Manufacturing: Integrates PROFIBUS-based servo drives, robotic controllers, and welding stations with a ControlLogix backbone.

• Packaging and Material Handling: Enables ControlLogix PLCs to master distributed PROFIBUS sensors, actuators, and remote I/O across conveyor or packaging lines.

• Process Skids & OEM Integration: Provides a clean gateway to incorporate PROFIBUS-enabled pre-built skids into an Allen-Bradley control system.

• Global Standardization: Supports multinational facilities using ControlLogix, enabling flexible sourcing of international I/O and instrumentation.

By using the SST-PB3-CLX, engineers ensure high-speed, reliable communication and protocol unification in mixed-vendor automation systems.

FAQ: WOODHEAD SST-PB3-CLX

Q1: What does "DP Remote I/O Scanner" mean?
A1: It means the module acts as a master on a PROFIBUS DP network, scanning all connected slave devices cyclically to read inputs and write outputs, ensuring synchronized communication with the PLC.

Q2: Does the SST-PB3-CLX require special programming software?
A2: No separate programming software is required. The module is configured using Add-On Instructions (AOIs) within RSLogix 5000 / Studio 5000, enabling straightforward integration and data mapping with familiar ControlLogix tools.

Q3: Why choose an in-chassis scanner module instead of an external gateway?
A3: Two main benefits:

1. Faster data exchange due to direct access to the high-speed ControlLogix backplane.

2. Simpler configuration because it integrates directly with the PLC’s memory structure, avoiding complex IP addressing or routing setups required by external gateways.
