ProSoft 5204-DFNT-PDPM | ProSoft DF1 to PROFIBUS Gateway

Product Overview

The ProSoft 5204-DFNT-PDPM is a dual-protocol communication gateway engineered to connect Rockwell Automation PLC environments with PROFIBUS-DP field networks. It provides a bidirectional data interface between DF1-over-Ethernet (DFNT) traffic and PROFIBUS-DP Master systems, enabling seamless integration of legacy field devices into modern Ethernet-based control architectures.

This module is designed for use in ControlLogix, CompactLogix, SLC 500, and PLC-5 platforms via ProSoft in-rack integration. It supports deterministic data exchange, real-time diagnostics, and flexible data mapping for complex multi-vendor automation systems.
