Industrial Ethernet processor with S7 communication, TCP/IP services and integrated IT functions

The CP 443-1 IT connects a SIMATIC S7-400 station to Industrial Ethernet and supports S7 communication, ISO transport, ISO-on-TCP, TCP, UDP, multicast, FETCH/WRITE, NTP, FTP, web access and e-mail functions.

CP service mapVerify the hardware and firmware version, S7-400 CPU support, rack and slot, IP and MAC parameters, connection table, FTP and HTTP use, time synchronization, partner port mode and saved STEP 7 configuration before exchange.

Network Services

Inventory every active service because ordinary Ethernet link status does not confirm S7, FTP, web or e-mail operation.

Connection table

Export the configured S7, ISO, TCP, UDP and FETCH/WRITE connections and note every partner address and active endpoint.

IT content

Back up FTP files, HTML pages, user access and mail parameters; these items may not be covered by a simple IP-address record.

Clock role

Record whether the CP receives SIMATIC time or uses NTP and verify server reachability after commissioning.

Description

6GK7443-1GX11-0XE0 is a legacy CP 443-1 IT with a 10/100 Mbit/s TP interface and an AUI/ITP interface. Siemens documents firmware V2.0 or later for the manual revision selected for this product.

The IT functions consume connection resources and depend on the loaded configuration. Preserve the IP plan, MAC handling, S7 connections, SEND/RECEIVE blocks, FTP users and files, HTML content, NTP settings and diagnostics before replacement.

FAQ

Can 6GK7443-1GX11-0XE0 replace an older CP 443-1 IT without rebuilding the S7 project?

Only after checking the installed hardware and firmware version against the Siemens compatibility chapter. Preserve the STEP 7 configuration, connection table, IP parameters, IT files and block calls, then verify every service after download.

Why can the LINK LED be on while S7 or FTP communication through 6GK7443-1GX11-0XE0 still fails?

LINK confirms the physical Ethernet path, not the configured service. Check the CP operating mode, IP and subnet data, configured connection, FTP resource use, user access, partner endpoint and the first NCM diagnostic events.

What data should be recorded before exchanging 6GK7443-1GX11-0XE0 in an S7-400 rack?

Save the hardware configuration, IP and MAC plan, S7 and SEND/RECEIVE connections, FTP and HTTP content, NTP settings and diagnostic buffer. Photograph the slot, cable type, partner port and LED state under normal operation.

How should the front LEDs of 6GK7443-1GX11-0XE0 be used to diagnose an intermittent network fault?

Record INTF, EXTF, RUN, STOP, LINK, FDX, FAST, TXD and RXD together when the fault occurs. Correlate the pattern with NCM diagnostics and partner-port counters before changing speed, duplex or configuration.

Which installation checks matter before fitting 6GK7443-1GX11-0XE0 into another S7-400 station?

Confirm the CPU is supported, the rack has P and K bus attachment, the selected slot is permitted and the configured communication load is suitable. Match the actual TP or AUI/ITP interface and partner settings.

How can 6GK7443-1GX11-0XE0 be reset without accidentally losing the network configuration?

Use the Siemens distinction between clear/reset and reset to factory defaults. Save the project and IT files first, record the current IP and MAC data, and reload the approved configuration before reconnecting production clients.
