For price details, please contact our customer service
The SIEMENS 6GK7343-1CX10-0XE0 CP 343-1 Lean is a powerful communications processor designed to connect the SIMATIC S7-300 automation system to Industrial Ethernet networks, with integrated PROFINET IO device functionality. Supporting essential protocols like TCP/IP, UDP, multicast, and SEND/RECEIVE (with and without RFC1006), this processor also enables Fetch/Write access, S7 communication (server), and PROFINET IO communication. Equipped with a built-in 2-port switch based on the ERTEC 200 platform, it allows seamless integration into Industrial Ethernet environments while simplifying network configurations with SNMP diagnostics and LAN-based initialization.
Overview
Designed with a compact and robust housing, the CP 343-1 Lean provides reliable communication in industrial environments. The module supports flexible connection to Industrial Ethernet via dual RJ45 interfaces with 10/100 Mbit/s autosensing capability. Its integrated diagnostic LEDs and compatibility with industrial-grade IE FC RJ45 connectors enhance usability and serviceability. Additionally, the module allows configuration-free replacement without PG and supports operation in both standard and expansion racks (ER), making it ideal for scalable automation applications requiring industrial-grade communication interfaces.
