Siemens 6GK7443-1EX30-0XE0 CP443-1 Communications Processor Industrial Ethernet For SIMATIC S7-400

Siemens 6GK7443-1EX30-0XE0 CP443-1 Communications processor Industrial Ethernet for SIMATIC S7-400

Product Overview
The Siemens 6GK7443-1EX30-0XE0 CP 443-1 EX30 is a high-performance Industrial Ethernet communications processor (CP) for the SIMATIC S7-400 PLC family.  It adds a 10/100 Mbps Ethernet interface to any S7-400 rack, enabling real-time data exchange, remote programming, diagnostics, and integration with SCADA, MES, or cloud platforms via standard TCP/UDP protocols.  With built-in web server, security features, and seamless TIA Portal configuration, the CP 443-1 EX30 future-proofs legacy S7-400 installations while maintaining deterministic performance.

Key Features & Benefits
• 1× 10/100 Mbps RJ-45 port – auto-negotiation & auto-crossover
• S7 communication (RFC 1006) – transparent PLC-to-PLC, PLC-to-HMI
• TCP/UDP open sockets – connect to SQL, MQTT, OPC UA, ERP systems
• Integrated web server – remote diagnostics via standard browser
• Full-duplex operation – 1 Gb/s switching fabric, no collision delays
• Security: IP access list, SSL/TLS, SNMPv3 – protect plant networks
• Hot-swap capable – install/remove while S7-400 is running
• UL, CE, ATEX Zone 2, marine approvals – global compliance

Typical Applications
• Retrofit S7-400 Ethernet connectivity
• Remote pump-station SCADA links
• Packaging line integration with MES
• Cloud data logging for energy monitoring
