More Information

Overview Manuals DP Network Comm Services Power & Climate Rack Setup

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).

All prices are shown in USD.

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.
Description
Siemens 6GK7443-5FX02-0XE0 is a CP 443-5 Basic PROFIBUS communication processor for the SIMATIC S7-400 system. It gives the controller a dedicated path for exchanging data with PROFIBUS communication partners instead of assigning that traffic to the CPU interface.

At its 9-pin Sub-D connector, 6GK7443-5FX02-0XE0 carries S7, FMS, S5-compatible, and PG/OP communication over one RS485 bus. The selected transmission rate determines the permitted cable reach, so bus speed, segment length, connector shielding, and end termination must be planned as one network arrangement.

Installed as a single-width S7-400 module, 6GK7443-5FX02-0XE0 uses the rack backplane for its 5 V supply and also requires the specified external 24 V feed. The chosen S7-400 CPU determines the permitted number of communication processors, linking rack placement and power planning to the station's available communication resources.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why can Siemens 6GK7443-5FX02-0XE0 communicate at 12 Mbit/s on one installation but not another?
Siemens 6GK7443-5FX02-0XE0 supports 12 Mbit/s, but the selected rate limits cable length and demands compliant connectors, shielding, and segment termination.
Which connector is required for the PROFIBUS port on 6GK7443-5FX02-0XE0?
The 6GK7443-5FX02-0XE0 uses a 9-pin Sub-D RS485 PROFIBUS interface, so the connector and terminating arrangement must match that physical layer.
Can 6GK7443-5FX02-0XE0 carry engineering-station traffic while normal controller communication is active?
Yes, 6GK7443-5FX02-0XE0 supports PG/OP and controller services, but connection resources should be allocated for the complete communication load.
What should be checked when 6GK7443-5FX02-0XE0 reports unstable PROFIBUS communication?
For 6GK7443-5FX02-0XE0, first check unique station addresses, the configured rate, cable reach, shield continuity, connector seating, and termination at both segment ends.
Does 6GK7443-5FX02-0XE0 require cabinet heat-load allowance?
The 6GK7443-5FX02-0XE0 has a specified 5 W power loss, which should be included in S7-400 enclosure thermal calculations.
How many 6GK7443-5FX02-0XE0 processors can be installed in one S7-400 station?
The allowable 6GK7443-5FX02-0XE0 count depends on the specific S7-400 CPU, so the CPU resource limits must be checked before adding modules.
