PRODUCT DESCRIPTION
6GK7443-5DX03-0XE0 PROFIBUS rack communication processor
Siemens 6GK7443-5DX03-0XE0 is the CP 443-5 Extended PROFIBUS communication processor for SIMATIC S7-400. It links a compatible rack controller to distributed PROFIBUS equipment and supported automation communication services.
The processor has a nine-pin D-sub RS485 interface and draws power from the 5 V rack backplane. Its DP master configuration supports up to 125 slaves, with separate limits for process data, S7 connections and SEND/RECEIVE channels. Engineering-tool support and CPU resource limits determine the final communication configuration.
