Siemens 6GK7443-1EX30-0XE0 Communications Processor

The 6GK7443-1EX30-0XE0 is a CP 443-1 Industrial Ethernet Communications Processor の シーメンス SIMATIC NET series. It is specially designed for SIMATIC S7-400 and S7-400H redundant PLC systems. This module connects PLC controllers to Industrial Ethernet and acts as a PROFINET IO Controller to realize real-time control of distributed field devices.

As the official upgraded version of the previous CP 443-1 EX20, it integrates a 2-port real-time Ethernet switch and supports bus and ring network topologies. It features Isochronous Real-Time (IRT) コミュニケーション, Media Redundancy, IP access control and extended diagnostics. It serves as the core communication module for Ethernet communication and PROFINET networking in medium and large automation systems. 現在, the entire S7-400 series has entered the end of its product lifecycle, and this model is mainly used for maintenance, expansion and fault replacement of existing systems.

Upgrade Replacements within the Same Series

Direct Upgrade: Fully replaces legacy models 6GK7443-1EX20-0XE0 and 6GK7443-1EX11-0XE0. Simply update the module model in STEP7 hardware configuration. It is backward compatible with all basic communication functions and adds new features including IRT real-time communication and MRP ring redundancy.

Higher-end Version: 6GK7443-1GX30-0XE0 (CP 443-1 高度な). 搭載 1 × Gigabit Ethernet port and 4 × 100 Mbps switch ports. It supports firewall, IPsec encryption, Web server, FTP, email and other IT functions, ideal for high-security and multi-port networking scenarios.

Migration for New Systems

Siemens next-generation platform is SIMATIC S7-1500 series, with the corresponding Ethernet module 6GK7543-1AX00-0XE0 (CP 1543-1).

> 注記: S7-1500 modules are completely incompatible with S7-400 racks and backplane buses. This is a full system migration solution and direct single-module replacement is not feasible.

4.3 互換性に関する注意事項

S7-400 systems with CPU firmware lower than V4.1 cannot operate with EX30 CP. Please upgrade CPU firmware to V4.1 or above first.

Native IT functions (FTP, Web server, 電子メール) supported by older CP models are removed in the standard EX30 version. Select GX30 Advanced version if IT functions are required.

交換時の注意事項

1. Configuration Modification: 交換後, you must change the module model to EX30 in STEP7 hardware configuration, recompile and download the project. Hot-swap without configuration update is not allowed.
2. CPU Firmware Compatibility: Replacing EX20 has no CPU firmware version restrictions and works with all S7-400 CPUs. Upgrading from earlier EX11/EX10 requires CPU firmware ≥ V4.1.
3. Interface Migration: If the old AUI/ITP coaxial interface was used, rewire to RJ45 Ethernet as the coaxial port is removed in EX30.
4. IT Function Migration: If the original system relies on FTP, Web server, email alarm and other IT functions, upgrade to 6GK7443-1GX30-0XE0 (上級版) since standard EX30 does not support these features.
5. Redundant System Compatibility: Single-module replacement is available for S7-400H systems. Dual-CP redundant configuration is also supported with full compatibility to original redundant communication mechanism.
