It enables Industrial Ethernet communication via ISO\/TCP (RFC1006) and supports PROFINET IO as either a controller or a device, making it suitable for integrating S7-300 into PROFINET IO networks. The module includes an integrated ERTEC 200 2-port switch, providing two RJ45 Ethernet ports at 10\/100 Mbit\/s for external network access and device-to-device connections on the same module. In addition to data exchange, it handles S7 communication, fetch\/write operations, and multicast support, and it offers DHCP capabilities, CPU synchronization, diagnostics, and LAN-based initialization to simplify setup and monitoring. This CP 343-1 variant is designed to extend legacy S7-300 installations with modern Industrial Ethernet and PROFINET connectivity, enabling scalable, modular networked automation configurations. \u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268622930154,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-018.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-ag-6gk7-343-1ex11-0xe0-ethernet-module","provider":"GTG Hardware","version":"1.0","type":"link"}
