Siemens 6GK7343-1EX30-0XE0 Ethernet Communication Module

The Siemens 6GK7343-1EX30-0XE0 Simatic Ethernet communication module enables Ethernet networking for PLCs in industrial automation, typically installed in SIMATIC S7-300 or S7-400 racks to connect HMIs, SCADA systems, and other networked devices at high speed. Powered from 24 VDC and designed for rack-mounted backplane integration, it offers two 10/100 Mbps RJ45 Ethernet ports and supports PROFINET, TCP/IP, UDP/IP, and ISO on TCP. With PROFINET conformance Class B and MPI/DP communication interfaces via the PLC backplane, this module handles routing, remote I/O, and broader industrial Ethernet tasks, while providing Link/Activity/Status LEDs and built-in diagnostics for network status and error reporting. Compatible with SIMATIC S7-300/S7-400 platforms, it serves factory automation, process control, and distributed systems requiring reliable Ethernet connectivity, including production lines, material handling, building automation, and remote monitoring. Cabling uses standard Cat5/6, and the module is commonly used for network expansion, remote access integration, and replacement of legacy interfaces. Common replacements include Siemens 6GK7343-1EX31-0XE0, 6GK7343-1EX30-0XE1, and 6GK7343-1GX30-0XE0.
