Communications processor for S7-400 PROFIBUS
This SIMATIC NET CP 443-5 BASIC (order code 6GK7443-5FX01-0XE0) connects a SIMATIC S7-400 to a PROFIBUS network, handling FMS, S5-compatible PG/OP, and S7 communication. It is a compact, single-width S7-400 module (25 mm wide, fits a single slot). The processor draws its supply from the 5 V backplane bus and dissipates 6.5 W. The PROFIBUS interface is a standard 9-pin Sub-D socket (RS485). Integration requires STEP 7 V5.1 SP1 or higher and NCM S7 for PROFIBUS. Maximum bus parameters depend on the CPU type — the 'depending on CPU type' note applies to the number of connections (up to 48 maximum, 14 per CPU).
