It draws 0.6 A at 5 VDC from the backplane bus, dissipating 3 W. The PROFIBUS interface is a 9-pin Sub-D socket (RS485). Configuration requires STEP 7 V5.4 SP4 or higher, or STEP 7 Professional V12 (TIA Portal) or higher. ## Configuration limits Planning note: the maximum number of CPs that can operate as DP masters depends on the number of CP 443-1 Advanced processors in the same S7-400 station. Up to 10 CPs total can be operated: up to 4 as PROFINET IO controllers (CP 443-1 Advanced) and up to 10 as DP masters (CP 443-5 Extended). Per DP master, up to 125 slaves are operable. The address range per DP slave is 244 bytes input and output. ## Comparison with 6GK7443-5FX02-0XE0 If you are cross-referencing from the 6GK7443-5FX02-0XE0: the physical footprint is identical (single-width, same dimensions) and both use the same 5 V backplane supply and 9-pin Sub-D PROFIBUS interface. The main difference is the software toolchain — this module requires STEP 7 V5.4 SP4 / TIA Portal V12, while the FX02 runs on STEP 7 V5.2 SP1 plus NCM S7. Power draw is lower here (3 W vs 5 W). It will drop into the same slot without rewiring, but the configuration environment may need updating.","metaTitle":"Siemens 6GK7443-5DX05-0XE0 CP 443-5 Extended, DPV1, Active","metaDescription":"Communications processor for S7-400 to PROFIBUS DP.
