More Information

Overview Manuals Protocol Services PROFINET IO 2-Port Switch Diagnosis & Access

Features:

  • The processor connects an S7-400 or S7-400H station to Industrial Ethernet through two RJ45 ports.
  • PROFINET IO, S7, TCP, ISO-on-TCP, ISO transport, and UDP services share the CP communication resources.
  • Web diagnostics, SNMP, IP access lists, and duplicate-address detection support managed operation.
The internal switch forwards local Ethernet traffic while the CP transfers controller data between the backplane and configured network connections.

PROFINET cyclic exchange and open communication use separate configured resources, so their connection and data-area limits are reviewed together.

Port indicators describe physical traffic, whereas the web pages and diagnostic buffer expose station and protocol events.

The Siemens 6GK7443-1EX20-0XE0 SIMATIC NET CP 443-1 Industrial Ethernet Communications 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.

Industrial Ethernet Communication Paths

  • S7 communication: PG, operator, and controller data exchange uses configured S7 connections.
  • Open communication: TCP, ISO-on-TCP, ISO transport, and UDP carry SEND/RECEIVE traffic.
  • Server access: FETCH/WRITE services expose assigned S7 data areas to configured external clients.
  • Multicast: Selected UDP connections distribute one datagram stream to registered multicast partners.

Controller Exchange with Distributed Devices

  • Controller role: The CP maps cyclic input and output data between the S7-400 station and PROFINET IO devices.
  • Device scale: One configured CP can control as many as 128 IO devices within its resource limits.
  • Shared device: Individual submodules of one IO device can be assigned to different controllers.
  • Prioritized startup: Selected IO devices can receive accelerated startup handling after network or station restart.

Local Ethernet Forwarding

  • RJ45 links: Two copper ports attach the S7 station and neighboring Ethernet equipment.
  • Port setup: Each port can use automatic negotiation or a configured fixed speed and duplex mode.
  • Address learning: The switch forwards frames according to learned source addresses and a five-minute aging time.
  • MRP ring: Media Redundancy Protocol provides a managed alternate path in ring topologies.

Condition Reporting and Communication Control

  • Web pages: Browser-based diagnostics expose station and CP information over the configured IP address.
  • SNMP: The SNMP agent supplies MIB-II management information to a network-management station.
  • IP access list: Configured partner addresses limit which IP nodes may communicate through the CP.
  • Duplicate address: An IP conflict produces BUSF indication and a diagnostic-buffer entry.
Description
Siemens 6GK7443-1EX20-0XE0 is a SIMATIC NET CP 443-1 communications processor that attaches an S7-400 or S7-400H station to Industrial Ethernet. Its integrated two-port switch places the controller station and adjacent Ethernet devices on two 10/100 Mbit/s RJ45 connections.

For controller and peer exchange, 6GK7443-1EX20-0XE0 carries S7 communication and SEND/RECEIVE traffic over ISO transport, ISO-on-TCP, TCP, and UDP. FETCH/WRITE services allow configured external partners to initiate server-side data access in the S7 station.

As a PROFINET IO controller, 6GK7443-1EX20-0XE0 exchanges cyclic data with as many as 128 IO devices. IRT, prioritized startup, and shared-device functions are available within the documented CPU, firmware, and configuration-tool boundaries.

Each switch port on 6GK7443-1EX20-0XE0 provides LINK and RXD/TXD indication and can be assigned automatic or fixed speed and duplex settings. MRP handles ring redundancy, while the switch learns destination addresses and removes aged entries after five minutes.

Diagnostic access to 6GK7443-1EX20-0XE0 includes web pages, SNMP data, connection diagnostics, and diagnostic-buffer extracts. IP access lists restrict communication partners, and duplicate IP detection records the conflict through the BUSF indication and diagnostic buffer.

What role does Siemens 6GK7443-1EX20-0XE0 perform in an S7-400 rack?
Siemens 6GK7443-1EX20-0XE0 gives the S7-400 or S7-400H station its Industrial Ethernet and PROFINET IO communication path.
How do the two RJ45 ports on 6GK7443-1EX20-0XE0 handle neighboring devices?
The integrated switch in 6GK7443-1EX20-0XE0 learns device addresses and forwards frames through the port that reaches each destination.
Which protocols can carry SEND/RECEIVE data through Siemens 6GK7443-1EX20-0XE0?
Siemens 6GK7443-1EX20-0XE0 supports SEND/RECEIVE over TCP, ISO-on-TCP, ISO transport, and UDP connections.
When does 6GK7443-1EX20-0XE0 need CPU firmware limits checked?
CPU firmware limits for 6GK7443-1EX20-0XE0 must be checked when PROFINET IO, MRP, IRT, or prioritized-startup functions are configured.
Why can Siemens 6GK7443-1EX20-0XE0 show BUSF while remaining in RUN?
