Product Overview

The Siemens 6GK7443-1EX11-0XE0 handles Ethernet communication for SIMATIC S7-400 systems. This communication processor connects the PLC to industrial Ethernet networks and IT environments. It supports data exchange between controllers and higher-level management systems. The unit integrates seamlessly into SIMATIC S7-400 programmable logic controller installations.

Technical Specifications

Physical Dimensions and Mounting

This communication processor measures 290 mm in depth, 25 mm in width, and 215 mm in height. The unit weighs approximately 0.70 kg. It plugs directly into a standard S7-400 slot using the backplane connector. The front panel includes LED indicators for power, link, activity, and diagnostic status. These LEDs provide immediate visual feedback on network communication health.

Connectivity and Communication Capabilities

The 6GK7443-1EX11-0XE0 features a single RJ45 Ethernet port for network connection. It handles both 10 Mbps and 100 Mbps data rates with auto-negotiation. The processor supports TCP/IP, UDP, ISO-on-TCP, and S7 communication protocols. It manages up to 64 simultaneous connections for versatile networking. The large data buffer stores incoming and outgoing data efficiently.

Network Performance and Data Handling

This communication processor transfers data at high speeds over Ethernet networks. The 64 KB receive buffer and 64 KB transmit buffer handle burst traffic effectively. It facilitates S7 communication between multiple controllers and HMIs. Furthermore, the processor supports UDP multicast for efficient data distribution. The module integrates with IT systems for remote access and data collection.

Installation and System Configuration

You can install this processor into any available slot in the S7-400 rack. Insert the module until it locks securely into the backplane. Assign the IP address using BootP or manual configuration methods. Configure the communication parameters in STEP 7 software before operation. For network security, implement appropriate firewall and access restrictions.

Environmental Compliance

This module carries CE marking and UL recognition for industrial use. It complies with RoHS environmental directives. The IP20 protection suits standard control cabinet installations.
