S7-400 PROFIBUS processor for PG/OP, S7, SEND/RECEIVE, FMS and time-synchronization services

The CP 443-5 Basic connects a SIMATIC S7-400 station to PROFIBUS through a 9-pin RS485 interface at up to 12 Mbit/s. It supports S7 routing, SIMATIC H redundant S7 communication and replacement without a programming device when the station project is prepared correctly.

PROFIBUS service map: Confirm the S7-400 CPU and rack, CP slot, STEP 7 and NCM project, firmware and hardware version, PROFIBUS address and baud rate, FMS or S7 connections, SEND/RECEIVE blocks, time role and bus termination.

Network Services

Inventory each protocol and connection resource before changing the CP or project.

Service map

List PG/OP, S7, SEND/RECEIVE and FMS partners, blocks, addresses and expected connection counts.

Routing and time

Record S7 routing paths, time-synchronization role and any redundant H-system communication.

Bus baseline

Capture station address, baud rate, reachable nodes, termination positions and normal diagnostic-buffer entries.

Description

6GK7443-5FX02-0XE0 is the Basic version of the CP 443-5. Its service set includes PG/OP, S7, open SEND/RECEIVE and PROFIBUS FMS; it should not be treated as the Extended variant or as an Ethernet CP.

A like-for-like replacement depends on the configured S7-400 station and communication resources. Save the project and diagnostic evidence before changing the module, then restore one service group at a time.

Fault Isolation

Separate rack, configuration and physical-layer faults before replacing the communication processor.

Rack status

Check CPU mode, module status, rack power and backplane communication before disturbing the PROFIBUS cable.

Physical layer

Inspect the 9-pin connector, shield bond, cable condition and termination at the actual segment ends.

Project compare

Compare the online module and configured CP version, then review the first NCM or CPU diagnostic event.

FAQ

Can 6GK7443-5FX02-0XE0 replace a CP 443-5 Extended without project changes?

No. This is the CP 443-5 Basic and its functions differ from the Extended model. Compare required DP, FMS, S7, routing and other services, then check the CPU, hardware catalog and configured CP type before substitution.

Why can PG access work through 6GK7443-5FX02-0XE0 while SEND/RECEIVE or FMS connections remain down?

PG/OP access uses a different configured service. Check the connection table, partner address, called blocks, resource limits and operating state for the failed service, then review NCM diagnostics instead of treating the physical link as fully proven.

What should be backed up before replacing 6GK7443-5FX02-0XE0 in an S7-400 rack?

Archive the complete STEP 7 and NCM project, online blocks, system data and diagnostic buffers. Record the rack and slot, CP version, PROFIBUS address and baud rate, service partners, time role, connector and termination layout.

How should I troubleshoot repeated PROFIBUS station loss on 6GK7443-5FX02-0XE0?

Read the first CP and CPU diagnostics, identify whether all stations or one branch disappears, then inspect shielding, connector seating, termination and cable limits. Verify the configured baud rate and node list before altering communication blocks.

What must be checked when moving 6GK7443-5FX02-0XE0 to another S7-400 station?

Confirm the target CPU supports the CP, the slot and backplane resources are suitable, and STEP 7 plus NCM contains the exact module entry. Rebuild the station and communication connections from an approved project, not from address notes alone.

How can S7 communication resource problems on 6GK7443-5FX02-0XE0 be distinguished from a cable fault?

If node visibility and PG access remain stable, inspect configured and active S7, FMS and SEND/RECEIVE connection counts and partner states. A cable fault more often changes bus diagnostics, reachable nodes or error counters across services.
