Siemens 6GK7343-1EX00-0XE0 Simatic Ethernet Processor

Siemens 6GK7343-1EX00-0XE0 is a CP 343-1 TCP communications processor that provides Ethernet connectivity for SIMATIC S7-300 PLCs, enabling direct integration of the controller into Industrial Ethernet networks and communication with other devices over TCP/IP. It supports S7 communications with fetch/write and SEND/RECEIVE RFC1006, includes multicast support, DHCP for dynamic addressing, and can operate as a PROFINET IO Controller or PROFINET IO Device, with two RJ45 LAN ports at 10/100 Mbps for straightforward network access and LAN initialization. Typical applications include extending S7-300 systems to Industrial Ethernet for data exchange with HMIs and SCADA systems, PLC-to-PLC messaging, and remote diagnostics within Siemens automation ecosystems. As a CP343-1 module, it is designed to replace or augment legacy S7-300 Ethernet connectivity when TCP/IP and S7 protocol support are required, delivering a compact, stand-alone Ethernet processor that fits within standard SIMATIC NET configurations.
