Siemens 6GK7443-1GX30-0XE0 Communication Processor

Siemens CP 443-1 Advanced communications processor, part number 6GK7443-1GX30-0XE0, is a plug‑in CP for SIMATIC S7‑400 that provides integrated Ethernet connectivity and S7 network capabilities. It combines 1x 10/100/1000 Mbps interface with a built‑in Industrial Ethernet switch offering four 10/100 Mbps RJ45 ports, for a total of five network connections. The device functions as a PROFINET IO controller and supports S7 communication, Open communication (SEND/RECEIVE), and S7 routing between networks. IP configuration can be done via DHCP or fixed addressing, and it includes an IP access control list and time‑of‑day synchronization for secure, scheduled operations. Additional features include extended web diagnostics, Fast Startup, PROFIenergy support, IP routing, FTP, a Web server, and email capabilities. Hardware power is supplied from the backplane bus at 5 V DC with typical current draw around 1.8 A (about 9 W). This CP 443‑1 Advanced module is suited for industrial automation environments that require reliable Ethernet access, S7 communication, and traffic routing across multiple networks within S7‑400 systems.
