Siemens 6GK7443-5FX00-0XE0 Profibus DP Interface Module

Siemens 6GK7443-5FX00-0XE0 is a SIMATIC NET CP 443-5 communications processor that connects a SIMATIC S7-400 controller to PROFIBUS DP, enabling DP-network communication for legacy automation configurations. The Basic variant supplies an FMS interface, a SEND/RECEIVE interface, and S7-function support, providing the core backplane communication capabilities and S7 integration features used in typical S7-400 projects. The module includes 1 x RS-485 PROFIBUS DP interface and is described as S5-compatible, with PG/OP and S7 communication support to facilitate data exchange between DP devices and S7 backplane devices. As part of the CP 443-5 family, this device serves as a bridge between older S7-400 installations and PROFIBUS DP networks. Industry Mall lists this exact variant as no longer available.
