Siemens 6GK7343-1GX30-0XE0 Communications Processor

Siemens 6GK7343-1GX30-0XE0 is a CP343-1 Advanced communications processor that connects a SIMATIC S7-300 CPU to Industrial Ethernet, enabling PROFINET IO controller or IO device operation (RT and IRT), S7 communication, and S5-compatible data exchange over TCP/IP, ISO, and UDP networks. The module provides three Industrial Ethernet interfaces and includes an integrated ERTEC 200 two-port switch, delivering two RJ45 ports for LAN connectivity at 10/100 Mbps while the remaining interface links the CP to the industrial network. Power is supplied via a 2-pole plug-in terminal block, and the unit supports C-PLUG removable storage for configuration data. Features and protocols supported include DHCP, multicast, S7 communication, PROFINET CBA, TCP/IP, ISO, UDP, and SNMP, making it suitable for integrating an S7-300 system into complex Ethernet-based automation architectures.
