172PNN21022 | Schneider Electric | Profibus DP Option Adapter

Product Overview

The 172PNN21022 is a fieldbus communication option adapter developed by Schneider Electric for the Modicon Momentum automation platform. This module enables Momentum I/O bases to interface directly with Profibus DP networks, allowing distributed I/O stations to communicate efficiently with higher-level control systems.

Designed for Profibus-based architectures, this adapter allows Momentum assemblies to operate as Profibus DP slaves, supporting deterministic data exchange with Profibus masters such as PLCs, DCS controllers, and supervisory systems.
