Siemens 6GK74431EX110XE0 Communication Module

Siemens 6GK74431EX110XE0 is a CP 443-1 communications processor for SIMATIC S7-400 that provides ISO/TC-based Ethernet connectivity between an S7-400 PLC and an industrial Ethernet network. It offers two 10/100 Mbit/s Ethernet interfaces (RJ45) and supports TCP/IP, ISO, S7 communication, Open Communication (SEND/RECEIVE), S7 routing, and PROFINET IO controller functionality to enable robust networked control. The module supports flexible IP configuration options including DHCP/BOOTP and static addressing, IP access control lists, time-of-day synchronization, and web-based diagnostics for straightforward setup and ongoing diagnostics. Typical applications include integrating S7-400 PLCs into plant Ethernet architectures, enabling data exchange and routing between S7 devices, and supporting PROFINET IO controller operation within industrial networks.
