6GK7343-1EX30-0XE0 Siemens CP 343-1 Communications Processor SIMATIC S7-300
The Siemens 6GK7343-1EX30-0XE0 is a high-performance Industrial Ethernet communication module from the SIMATIC S7-300 automation family, known as the CP343-1. Designed for seamless integration of S7-300 programmable logic controllers (PLCs) into modern industrial networks, this module enables fast, secure, and reliable data exchange over 10/100 Mbps Industrial Ethernet using standard TCP/IP, ISO-on-TCP, UDP, and Siemens-specific protocols like S7 Communication.
Ideal for factory automation, process control, and infrastructure applications, the 6GK7343-1EX30-0XE0 supports PROFINET IO Controller or IO Device functionality, allowing S7-300 systems to act as central controllers or distributed nodes in PROFINET networks. With integrated IT security features—including MAC address-based port protection, access control lists (ACLs), and secure firmware updates—it meets the demands of Industry 4.0 and networked production environments.
Housed in a compact, DIN-rail mountable format that slots directly into the S7-300 rack, the CP343-1 requires no external power supply and features an RJ45 port with auto-negotiation and auto-crossover (Auto-MDI/MDIX) for plug-and-play connectivity.
