The rack supports up to 10 CPs total: up to 4 as PROFINET IO controllers (CP 443-1 Advanced) and up to 10 as DP masters (CP 443-5 Extended). Plan your slot assignments and backplane power budget accordingly — the module draws 1 A from the 5 V backplane bus and dissipates 5 W. ## Environment and connectivity Rated for 0 to 60 °C operating temperature and IP20 protection — fine for a ventilated control cabinet, even in dusty environments like a mill or crusher house. The PROFIBUS interface uses a 9-pin Sub-D (RS485); the module requires STEP 7 V5.4 SP4 or higher with NCM S7 for PROFIBUS. Power is supplied from the backplane bus at 5 V DC.","metaTitle":"Siemens 6GK7443-5DX04-0XE0 CP 443-5 Extended, DPV1","metaDescription":"Siemens CP 443-5 Extended for S7-400 PROFIBUS DP master.
