Product Overview

The 6GK7443-1EX30-0XE0 is a high-performance Industrial Ethernet interface designed for the SIMATIC S7-400 controller series. Functioning as a specialized communications processor, this module offloads network management tasks from the central CPU to ensure deterministic system performance. It features a dual-port RJ45 interface with an integrated switch, enabling the construction of linear or ring network topologies without additional external hardware. By supporting a broad spectrum of protocols—from standard TCP/IP to real-time PROFINET IO—this processor serves as the backbone for complex, multi-vendor automation architectures requiring high-speed data exchange and robust network security.

Architecture & Network Capabilities

• Physical Interface: Dual 10/100 Mbit/s RJ45 ports with auto-sensing and auto-crossover.

• Protocol Support: PROFINET IO Controller, ISO, TCP, UDP, and S7-Communication.

• Addressing Services: Flexible IP assignment via DHCP or parameterized configuration blocks.

• Security Layers: Integrated IP Access Control List (ACL) to prevent unauthorized network entry.

• Efficiency Tools: PROFIenergy support for coordinated energy management during production standbys.

• Diagnostic Suite: Comprehensive web-based diagnostics for remote health monitoring and FTP server functionality.

• Time Management: Network-wide clock synchronization via NTP or SIMATIC procedures.

• Form Factor: Single-width module for S7-400 rack mounting.

• Net Weight: 0.7 kg (Note: Standard module weight is lighter than shipping weight).

Industrial Connectivity Solutions

• PROFINET IO Networks: Acting as a central controller to manage decentralized field devices, sensors, and actuators in real-time manufacturing environments.

• Cross-Network Programming: Utilizing S7-Routing to allow engineers to program and diagnose PLCs across different network boundaries from a single access point.

• Enterprise Integration: Providing a secure bridge for sending production data to higher-level MES or ERP systems using standard Open Communication (SEND/RECEIVE).

• Redundant Architectures: Implementing high-availability communication paths in critical infrastructure, such as power plants or water treatment facilities, using standardized redundancy protocols.

• Rapid System Recovery: Leveraging Fast Startup capabilities to minimize initialization times after power cycles in time-sensitive logistics and sorting systems.
