Description

About the CP 443-1 Communications processor CP 443-1; 2x 10/100 Mbit/s (IE switch); RJ45 ports; ISO; TCP; UDP; PROFINET IO controller; S7 communication; Open communication (SEND/ RECEIVE); S7 routing; IP configuration via DHCP/ Block; IP Access control list; time-of-day synchronization; extended web diagnostics; Fast Startup; Support for PROFIenergy

The Siemens CP 443-1 (6GK7443-1EX30-0XE0) is a communication processor that links a SIMATIC S7-400 CPU to Industrial Ethernet via an integrated 2-port switch, offering 10/100 Mbit/s over two RJ45 ports with PROFINET IO controller support for up to 128 IO devices. It also handles S7 communication, open communication (SEND/RECEIVE), S7 routing, and IP-based access control, drawing 5 V from the backplane bus at 1.4 A typical.

Selection Notes

The 128-device PROFINET IO controller capacity and 64 IRT-capable devices make this the CP to choose over the CP 343-1 when the station needs a larger, isochronous-capable IO network on an S7-400 backplane rather than S7-300. Four external PROFINET IO lines per rack allow splitting that device count across separate physical lines for cable-length or segmentation reasons, and the ACL and port-blocking security functions isolate the Ethernet segment without extra hardware.

Applications

Connects S7-400 CPUs to Industrial Ethernet/PROFINET networks in larger machine and process control systems that need S7 routing between subnets, open communication with third-party Ethernet devices, and centralized time synchronization via NTP or SICLOCK.
