6GK7443-1RX00-0XE0 SIEMENS Exclusive CP 443-1 RNA PROFINET Redundant Ethernet Processor Original Brand New

The SIEMENS 6GK7443-1RX00-0XE0 is a high-performance communications processor CP 443-1 RNA, specifically designed for redundant network access in SIMATIC S7-400 or S7-400H environments. It features three RJ45 ports including one for standard Ethernet communication and two for PRP (Parallel Redundancy Protocol), supporting ISO, TCP, UDP, and S7 communication. The module is ideal for high-availability industrial automation networks that require uninterrupted communication with fast fault tolerance.

Overview

This advanced communication module enables connection of S7-400 systems to Industrial Ethernet and supports multiple protocols including PG/OP communication, open SEND/RECEIVE, and S7 routing. With support for PRP as per IEC 62439-3, it ensures zero switchover time by simultaneously sending data frames across dual independent networks (LAN A and LAN B). The CP 443-1 RNA is suitable for applications requiring high uptime, such as fail-safe operations using S7-400 F-CPU and PROFIsafe. The PRP feature can also be disabled, allowing operation as a standard Ethernet processor.
