Siemens 6GK7343-1CX00-0XE0 Ethernet Communication Processor

Siemens CP 343-1 Lean Ethernet Communication Processor, model 6GK7343-1CX00-0XE0, adds Industrial Ethernet connectivity to a SIMATIC S7-300 PLC. It provides a 10/100 Mbit/s RJ45 Ethernet interface and includes an integrated ERTEC 200 two-port switch for LAN connectivity, enabling TCP/IP and UDP communications, multicast, RFC1006, and S7 communication (server) with PROFINET IO device integration. The module operates with SNMP diagnostics and initialization via LAN and supports loadable communication blocks to extend its protocol capabilities. Designed for SIMATIC NET environments, this CP 343-1 Lean enables S7-300 to interface with Ethernet networks through RFC1006, S7 server functionality, and standard Industrial Ethernet protocols while maintaining compatibility with backplane power and field network topology.
