Siemens 6GK7443-1BX00-0XE0 Profinet Interface Module

Siemens 6GK7443-1BX00-0XE0 Profinet Interface Module is a CP 443-1 communications processor option that functions as a PROFINET IO controller within SIMATIC S7-400 networks. It provides two Ethernet interfaces with an integrated PROFINET/I/O switch for scalable, robust IO networking, and supports PROFINET IO controller operation, S7 communication, and Open Communication (SEND/RECEIVE) with S7 routing. Configuration is performed with STEP 7 (V5.5 SP3 or higher) or STEP 7 Professional, with IP configuration via DHCP or static addressing and IP access control lists, plus time-of-day synchronization and extended web diagnostics. Security features include password protection for Web applications, ACL-based access control, the option to disable unneeded services, and a log for unauthorized access, with a built-in Web server and support for email and SNMP/MIB management. The BX00 variant supports PROFIenergy, IP routing, and network redundancy options such as ring redundancy with an MRP-capable topology, making it suitable for distributed automation, factory networks, and multi-protocol PROFINET installations requiring reliable IO control, remote diagnostics, and flexible network resiliency.
