PROFIBUS SST-PFB3-VME PROFIBUS DP communication interface module

Description

Product Overview

The SST-PFB3-VME is a high-performance, industrial-grade PROFIBUS DP communication interface module developed by ProSoft Technology (formerly SST/Woodhead/Molex), exclusively engineered for standard VME bus industrial control architectures. Serving as a dedicated hardware-based fieldbus protocol processor and high-speed data bridging unit, this module acts as the core communication gateway connecting VME-backplane industrial control hosts and on-site PROFIBUS DP fieldbus networks. It independently undertakes full PROFIBUS protocol stack parsing, cyclic process data exchange, acyclic parameter access, network status monitoring and intelligent fault diagnosis, completely offloading complex protocol computing tasks from the main CPU of VME-based PLC, DCS and embedded control systems. This hardware-offload design effectively eliminates host CPU resource occupation, reduces system communication delay and greatly improves the overall stability and real-time performance of industrial distributed control networks.

Manufactured in strict accordance with IEEE 1014 VMEbus international industrial standards and PROFIBUS DP-V0/DP-V1 official fieldbus specifications, the SST-PFB3-VME adopts an independent on-board dedicated RISC processor and full hardware protocol acceleration architecture, differing fundamentally from ordinary software-resolved VME communication cards. Equipped with 512 KB shared dual-port RAM and 512 KB independent Flash memory, the module supports standalone firmware operation and local data caching without relying on system resources. It features configurable PROFIBUS Master/Slave dual working modes, full baud rate adaptive transmission and 1500 VAC high-isolation safety protection, achieving zero-adaptation compatibility with GE Fanuc Series 90-70 and RX7i mainstream VME control systems. Every unit undergoes strict factory full-baud-rate communication calibration, protocol consistency testing, high-low temperature cycle durability verification and 72-hour full-load aging inspection, fully complying with global industrial e-commerce spot sales, large-scale engineering batch procurement and full lifecycle quality traceability standards. It is a core essential upgrade and replacement component for new construction and renovation of industrial VME fieldbus communication systems.
