Description

Product Description

The 6ES7443-1EX20-0XE0 (CP 443-1 Advanced) is a high-performance communication processor designed for the Siemens SIMATIC S7-400 PLC family. It provides a robust gateway for Industrial Ethernet connectivity and acts as a PROFINET IO controller, enabling seamless integration of distributed I/O and drive systems. Supporting both Real-Time (RT) and Isochronous Real-Time (IRT) communication, this module is engineered for high-speed, deterministic data exchange in complex automation architectures. With a factory-set MAC address and integrated remote maintenance functions, it ensures secure and reliable network management in demanding process and manufacturing environments.
