Overview

The Molex 5136‑PFB‑VME (also branded under SST/Woodhead/Softing) is a flagship communication module that allows VMEbus‑based controllers or embedded systems to seamlessly connect to PROFIBUS‑DP networks. It integrates a dedicated communication processor and onboard memory, enabling independent handling of the PROFIBUS protocol stack. This design significantly reduces the load on the host CPU, ensuring high-speed, deterministic, and reliable communication in complex automation environments.

Technical Data

Typical Applications

• Industrial automation systems requiring PROFIBUS‑DP connectivity for VME controllers.

• Process control in oil & gas, chemical, and power generation industries.

• Factory automation with distributed I/O, PLCs, and intelligent instruments.

• Retrofit projects integrating legacy VMEbus systems into modern PROFIBUS networks.

• High-data throughput environments needing real-time communication and reduced CPU load.

Key Features

• Dual role capability: Operates as either a PROFIBUS Master (Class 1 or 2) or Slave.

• Independent protocol handling: Offloads PROFIBUS stack processing from the host CPU.

• Seamless integration: Provides interoperability with a wide range of PROFIBUS-compatible devices.

• Robust design: Built to withstand demanding industrial environments.

• Technical support: Backed by Molex/Softing expertise in fieldbus communication.
