Siemens 6GK7443-5DX04-0XE0 is a CP 443-5 Extended communications processor for SIMATIC S7-400. It connects an S7-400 system to PROFIBUS DP and supports S5-compatible, PG/OP and S7 communication.
This CP 443-5 Extended version has been discontinued. Siemens identifies 6GK7443-5DX05-0XE0 as the successor. In an existing installation, replacement or migration should take the firmware version, PROFIBUS network configuration and the functions used in the STEP 7 project into account.
CP 443-5 Extended documentation is available from Siemens Industry Online Support. Other S7-400 communications processors in our catalog include 6GK7443-1EX11-0XE0 and 6GK7443-1GX11-0XE0.
If the module is operating in an existing PROFIBUS network, preserve the project configuration and check the module version before replacement. We can help verify the installed part number and possible replacement path.
