PROFINET IO Controller/Device Integrated 2-port ERTEC 200 switch Supports ISO and TCP/IP S7 communication RFC1006 support DHCP and NTP-CPU Sync

Product description

The Siemens 6GK7343-1EX30-0XE0 is a Communications Processor (CP) 343-1 for connecting SIMATIC S7-300 to Industrial Ethernet. It supports ISO and TCP/IP protocols and can function as a PROFINET IO controller or PROFINET IO device. This module features an integrated 2-port ERTEC 200 switch, simplifying network connections. It handles S7 communication, fetch/write, SEND/RECEIVE RFC1006, and Multicast. Additional features include DHCP, NTP-CPU sync, and initialization via LAN, with two RJ45 connections for 10/100 Mbit/s.

This communication processor is well-suited for applications requiring robust Ethernet connectivity and PROFINET capabilities for S7-300 systems. The integrated switch reduces external hardware needs, making it ideal for space-constrained control cabinets. It is widely used in manufacturing, automation, and process industries.
