SIMATIC S7-400 · INDUSTRIAL ETHERNET
S7-400 communications processing for Industrial Ethernet, open communication and PROFINET IO control.
Siemens 6GK7443-1EX20-0XE0 is a CP 443-1 communications processor connecting SIMATIC S7-400 systems to Industrial Ethernet. Siemens specifies ISO, TCP/IP and UDP communication, S7 communication, fetch/write and send/receive services, plus PROFINET IO controller operation. The integrated ERTEC 400 real-time switch provides two RJ45 ports at 10/100 Mbit/s. The processor supports DHCP, SNMP, web diagnostics, LAN initialization, IP access-list protection and ring redundancy. Replacement planning should verify the S7-400 rack and CPU, STEP 7 project, firmware, IP configuration, PROFINET device assignments, security settings and network topology before migration or exchange.
