Features:
- One 9-pin Sub-D RS485 interface connects the S7-400 station to PROFIBUS.
- Selectable rates from 9.6 kbit/s to 12 Mbit/s support different bus lengths and station layouts.
- S7, FMS, S5-compatible, and PG/OP services share the communication processor.
Siemens 6GK7443-5FX02-0XE0 gives a SIMATIC S7-400 rack a dedicated CP 443-5 Basic path to PROFIBUS partners.
The 6GK7443-5FX02-0XE0 interface uses RS485 physical transmission, with the network rate selected to match cable length and station planning.
Because 6GK7443-5FX02-0XE0 supports several communication services, connection resources and bus parameters should be checked together during configuration.
The Siemens 6GK7443-5FX02-0XE0 CP 443-5 Basic PROFIBUS Communication Processor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

PROFIBUS Network Planning
- Physical layer: The interface uses RS485 through a 9-pin Sub-D connector.
- Bus rate: The configured data rate can range from 9.6 kbit/s to 12 Mbit/s.
- Cable reach: Permitted segment length depends on the selected transmission rate.
- Termination: Both ends of each PROFIBUS segment require correct bus termination.
Supported Communication Paths
- S7 communication: Controller communication can use configured S7 connections.
- FMS service: Fieldbus Message Specification communication is available for suitable partners.
- S5-compatible service: Legacy SEND/RECEIVE-style communication is supported.
- Engineering access: PG and OP communication shares processor resources with other services.
Electrical and Environmental Limits
- Backplane load: Typical current consumption from the 5 V backplane is 1 A.
- External supply: The 24 V input draws approximately 1.2 A under stated conditions.
- Heat loss: Rated power loss is 5 W for cabinet thermal planning.
- Ambient range: Operation is specified from 0 to 60 °C with IP20 protection.
S7-400 Installation Checks
- Module format: The processor occupies one standard S7-400 module width.
- Station capacity: Permitted processor count depends on the installed S7-400 CPU.
- Address plan: The PROFIBUS address must be unique within the connected network.
- Commissioning: Connector seating, shielding, termination, and selected rate should be verified before traffic testing.
