  • Operates as a PROFINET IO controller for distributed I/O within the documented device and data limits.
  • Supports S7 communication, ISO transport, ISO-on-TCP, TCP, UDP, and open send/receive communication.
  • Provides S7 routing, IP access control, time synchronization, extended web diagnostics, and Fast Startup.
  • PROFIenergy support enables coordinated energy-management functions in an engineered PROFINET system.
  • Conformal coating supports use in demanding industrial environments within the stated SIPLUS limits.

Product Identity

Manufacturer: Siemens

Model: 6AG1443-1EX30-4XE0

Product Type: SIPLUS NET CP 443-1 Industrial Ethernet Communication Processor

04Applications

  • Industrial Ethernet and PROFINET integration for SIMATIC S7-400 controllers.
  • Machine and process cells requiring S7, TCP, UDP, or ISO communication.
  • SIPLUS installations requiring conformal-coated communication hardware.
  • Maintenance of an installed CP 443-1 configuration with the exact 6AG1443-1EX30-4XE0 article number.

05Lifecycle & Replacement

  • The current product phase is Phase Out Announce; confirm commercial availability at the time of quotation.
  • This article superseded earlier CP 443-1 generations, but CPU firmware and PROFINET controller constraints must still be reviewed.
  • Back up the STEP 7 project and record the rack slot, IP parameters, subnet, S7 connections, open communication blocks, access list, time settings, and device names before exchange.
  • Match the full SIPLUS article number; the standard 6GK base article does not provide the same environmental construction.
  • After replacement, verify module diagnostics, link status, IP configuration, every configured connection, PROFINET devices, routing, time synchronization, alarms, and process communication.

FAQFrequently Asked Questions

What is Siemens 6AG1443-1EX30-4XE0?
