The number of CPs that can be operated depends on the CPU type — the 'depending on CPU type' note means compatibility is not universal across the S7-400 range. Configuration requires STEP 7 V5.2 SP1 or higher with NCM S7 for PROFIBUS. No PROFINET interface on this module; only the 9-pin Sub-D RS485 port at interface 1. ## Physical fit and power Single-width compact module, 25 mm wide, slides into any S7-400 rack slot. Draws 1 A typical from the 5 V backplane bus, dissipating 5 W. IP20 rated, so no special enclosure for basic industrial environments. Operating range 0 to 60 °C; transport and storage range -40 to +70 °C. ## Cross to 6GK7443-5DX05-0XE0 The 6GK7443-5DX05-0XE0 Extended variant is the closest functional sibling. It cuts power loss to 3 W, uses 0.6 A typical, and requires STEP 7 V5.4 SP4 or TIA Portal V12.","metaTitle":"Siemens 6GK7443-5FX02-0XE0 CP 443-5 Basic, 5V DC, 1A","metaDescription":"Siemens 6GK7443-5FX02-0XE0 spare-part communications processor for S7-400 to PROFIBUS FMS, 5V DC backplane, 1A, 5W, IP20.
