Siemens 6GK7 343-1EX20-0XE0 Ethernet Communications Processor

Siemens CP 343-1 Ethernet Communications Processor, 6GK7343-1EX20-0XE0, is a plug-in module for SIMATIC S7-300 PLCs that provides an industrial Ethernet interface for TCP/IP communications and RFC1006 S7 data exchange with remote devices. Built to integrate S7-300 systems into modern Ethernet networks, it enables S7 communication, fetch/write, and Send/Receive operations over TCP/IP, supports multicast, and can function as a PROFINET IO controller or device depending on configuration, with LAN-based initialization and optional diagnostic capabilities. The CP 343-1 family delivers 10/100 Mbit/s Ethernet connectivity and is designed to extend SIMATIC NET communications without modifying the central CPU, making it a dedicated Ethernet communications processor for industrial automation networks.
