        Overview Manuals Ethernet & RNA PRP Operation Connection Limits Diagnostics

        Features:

        • A standard 10/100 Mbit/s Ethernet port or the dual-port RNA interface connects the S7-400 station.
        • PRP operation uses two 100 Mbit/s RNA ports for redundant network paths.
        • Industrial protocols, web diagnostics, SNMPv1, time synchronization, and IP conflict detection aid operation.
        Either a standard Ethernet LAN or a redundant PRP architecture can connect through Siemens 6GK7443-1RX00-0XE0 to S7-400 or S7-400H controllers.

        The 6GK7443-1RX00-0XE0 RNA interface contains two RJ45 ports, while the separate standard Ethernet port supports conventional 10/100 Mbit/s communication.

        Connection planning for 6GK7443-1RX00-0XE0 must account for the shared total, H, PG, OP, and open communication limits before project download.

        The Siemens 6GK7443-1RX00-0XE0 CP 443-1 RNA Redundant Network Communication Processor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Alternative Network Interfaces

        • Standard LAN: One RJ45 port supports 10 and 100 Mbit/s Ethernet.
        • RNA path: Two RJ45 ports provide 100 Mbit/s redundant-network connectivity.
        • Selection rule: Standard Ethernet and RNA interfaces are alternative operating modes.
        • Cabling check: Port assignment must match the configured interface mode before startup.

        Parallel Redundancy Protocol

        • Redundant paths: PRP sends traffic across two independent network paths.
        • Port pair: The two RNA ports form the processor connection to the redundant LANs.
        • Single-port mode: One RNA port can be active when a nonredundant RNA connection is configured.
        • Topology check: Both redundant LANs require distinct, correctly planned switching paths.

        Communication Resource Planning

        • Total resources: The processor supports up to 128 communication connections.
        • H communication: Up to 62 H connections are supported.
        • Operator access: Limits include 2 PG and 30 OP connections.
        • Open communication: SEND/RECEIVE services can use up to 64 connections in total.

        Commissioning and Fault Visibility

        • Browser access: Integrated web diagnostics expose processor and network status.
        • Network monitoring: SNMPv1 supports standard management queries.
        • Address conflict: Duplicate IP addresses are detected during startup and operation.
        • Time base: Time synchronization supports coordinated diagnostic records across the station.
        Description
        Siemens 6GK7443-1RX00-0XE0 is a CP 443-1 RNA redundant-network communication processor for SIMATIC S7-400 and S7-400H stations. It connects controller communication services either to a standard Industrial Ethernet segment or to a redundant RNA network.

        Interface selection on 6GK7443-1RX00-0XE0 is exclusive: the single standard Ethernet port and the two RNA ports are not active as parallel independent networks. When RNA is selected for PRP operation, the paired ports send the traffic across two separately planned LAN paths so the receiving node can accept the first valid duplicate frame.

        Communication services in 6GK7443-1RX00-0XE0 share a total pool of 128 connections. S7 and H communication, PG and operator access, and open SEND/RECEIVE traffic each consume resources within that pool and also remain subject to their documented service-specific limits.

        For network supervision, 6GK7443-1RX00-0XE0 exposes processor status through web diagnostics and SNMPv1, detects duplicate IP addresses, and applies time synchronization to diagnostic records. These functions relate the configured address and time base to the faults reported for each selected network path.

        Technical notes
        Standard Ethernet and PRP-network connection are alternative operating paths on Siemens 6GK7443-1RX00-0XE0; they are not used simultaneously.

        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.
        VIEW ALL FAQS
        Can 6GK7443-1RX00-0XE0 use its standard Ethernet port and RNA ports at the same time?
        No, 6GK7443-1RX00-0XE0 uses either the standard Ethernet interface or the RNA interface, so the project and cabling must select one path.
        What happens if 6GK7443-1RX00-0XE0 detects a duplicate IP address during startup?
        A startup IP conflict prevents 6GK7443-1RX00-0XE0 from entering normal communication until the duplicate address is removed and the configuration is corrected.
        Why are two network paths required for PRP on 6GK7443-1RX00-0XE0?
        The 6GK7443-1RX00-0XE0 PRP interface uses two independent LAN paths so duplicate frames can reach the destination without switchover delay.
        How should connection resources be budgeted on 6GK7443-1RX00-0XE0?
        For 6GK7443-1RX00-0XE0, check the 128-connection total together with the separate H, PG, OP, and open communication limits.
        Which diagnostics are available without STEP 7 on 6GK7443-1RX00-0XE0?
        The 6GK7443-1RX00-0XE0 provides browser-based diagnostics and SNMPv1 information that can assist network checks without opening the engineering project.
        Can one RNA port of 6GK7443-1RX00-0XE0 be used without full PRP redundancy?
        Yes, 6GK7443-1RX00-0XE0 can use one active RNA port, but that arrangement does not provide the two-path resilience of PRP.
