S7-400 Ethernet processor with two 100 Mbit/s PRP ports and a separate 10/100 Mbit/s plant-network port

The CP 443-1 RNA provides Parallel Redundancy Protocol access for SIMATIC S7-400 systems while supporting S7 and H communication, ISO, ISO-on-TCP, TCP, UDP, routing, time synchronization, access control and web diagnostics.

PRP design checkpoint: Document the independent PRP LAN A and LAN B paths, the separate first Ethernet interface, IP settings, communication resources, STEP 7 hardware entry, ACL rules, time source and normal web-diagnostic state before replacement.

PRP Network Design

Keep the two redundant LANs physically and logically distinct while preserving the non-PRP interface configuration.

LAN A / LAN B

Trace and label both 100 Mbit/s paths end to end; do not cross-connect the parallel networks.

Interface map

Record the first 10/100 port separately from the two PRP ports and preserve every IP and route assignment.

Traffic baseline

Capture normal communication partners, web diagnostics and redundancy status before disturbing cables.

Description

6GK7443-1RX00-0XE0 is a CP 443-1 RNA for redundant Ethernet access, not a conventional two-port ring switch. Its two PRP ports carry duplicated traffic across two parallel networks while the first interface serves the configured plant communication path.

A reliable exchange requires the approved S7-400 project and a port-by-port network map. LAN A and LAN B must remain separate and consistently assigned from the CP to the redundancy partner network.

Security & Time

Connectivity can fail even with link LEDs present when port control, ACL or time settings are not restored.

Access rules

Back up IP ACL and routing ACL entries and verify any intentionally disabled services or blocked ports.

Time source

Preserve NTP or secure-NTP settings and the configured time-forwarding role.

Service test

Validate S7, H and open communication separately after the PRP paths are healthy.

FAQ

How can I confirm that 6GK7443-1RX00-0XE0 fits my S7-400 and PRP architecture?

Verify the S7-400 CPU and hardware project, STEP 7 V5.5 SP2 plus the required HSP, and a PRP design with two independent 100 Mbit/s LANs. Also confirm the separate 10/100 Mbit/s interface and required S7, H or open communication services.

What cable information should I capture before replacing 6GK7443-1RX00-0XE0?

Label the first Ethernet port and both PRP ports individually, then trace PRP LAN A and LAN B to their respective switches. Record IP settings, partner devices, normal link state and web-diagnostic status before moving any cable.

Why can 6GK7443-1RX00-0XE0 continue communicating after one PRP path fails?

PRP sends duplicated frames over two independent networks, so one healthy path can maintain communication. Use web diagnostics and the physical network map to locate the failed LAN without treating continued traffic as proof that both paths are healthy.

Why do links appear active on 6GK7443-1RX00-0XE0 while an S7 or TCP partner remains unreachable?

Check the configured interface, IP subnet and route first, then review ACL entries, blocked physical ports and disabled services. A link LED confirms the physical connection but does not confirm that the required protocol is permitted or correctly routed.

How should I commission 6GK7443-1RX00-0XE0 after a module exchange?

Restore the approved hardware configuration, verify the first interface, bring up PRP LAN A and LAN B one at a time, compare web diagnostics with the baseline, and then test S7, H and open communication plus time synchronization individually.

What evidence should accompany a sourcing request for 6GK7443-1RX00-0XE0?

Provide the complete order number, CPU and rack details, current hardware and firmware information, STEP 7 version, required PRP topology, interface map and communication services. This prevents substitution with a non-RNA CP 443-1 variant.
