Allen Bradley 20-COMM-P PowerFlex Profibus Communication Adapter

Product Introduction

The Allen-Bradley 20-COMM-P PowerFlex Profibus Communication Adapter is a dedicated communication interface designed to integrate PowerFlex drives into Profibus DP industrial networks. It provides a reliable conversion from the internal DPI (Drive Peripheral Interface) communication protocol to the widely used Profibus DP fieldbus standard.

This adapter supports both single-drive and multi-drive modes, allowing flexible system configurations depending on application requirements. It is particularly suitable for systems where multiple drives need to be controlled through a single network node, reducing hardware complexity and improving communication efficiency.

With automatic baud rate detection up to 12 Mbps, the module simplifies network setup and ensures compatibility with the Profibus master. It also includes byte-swapping functionality to support both Intel and Motorola data formats, enhancing interoperability across different control systems.

Compact in design, the 20-COMM-P mounts directly onto PowerFlex drives, providing a streamlined and efficient solution for industrial communication integration.
