SST‑PFB‑CLX ControlLogix PROFIBUS‑DP Master Scanner Module

SST‑PFB‑CLX is a PROFIBUS‑DP master scanner communication module for Rockwell ControlLogix 1756 chassis platform. It acts as an intelligent co‑processor, realizing high‑speed data exchange between ControlLogix PLC and PROFIBUS‑DP slave devices via backplane bus, solving multi‑brand equipment interconnection in heterogeneous automation systems.

This module supports DP‑V0 / DP‑V1 protocol, baud rate ranges from 9.6 kbps up to 12 Mbps, and connects up to 125 slave stations. It adopts single‑slot plug‑in installation, configured by dedicated PBWork software, widely used as spare replacement for manufacturing, petrochemical and power industry ControlLogix cabinet retrofit and maintenance projects.
