Siemens 6GK7443-1EX11-0XE0 is a SIMATIC-S7-400 communications processor CP 443-1 for connecting an S7-400 station to Industrial Ethernet. The exact Siemens Industry Mall data clearly assigns the MLFB to the S7-400 family. The module has an Industrial Ethernet interface with 10 to 100 Mbit/s. RJ45 and AUI are available as physical connections, with the AUI connection being a 15-pin Sub-D socket. ISO, TCP/IP, UDP and RFC1006 as well as S7 communication and open communication are supported. The documented communication services also include Fetch/Write and Send/Receive with or without RFC1006. Siemens lists up to 48 S7 connections and up to 64 connections for open communication. The maximum user data length is 8 KiB over ISO/TCP and 2 KiB over UDP. The supply is provided with 5 V DC from the S7-400 backplane bus. The typical current consumption is 1.4 A, the power loss is 8.6 W. Protection class IP20 and permissible operation from 0 to 60 °C require installation in a suitable control environment. The compact S7-400 module occupies a single assembly width and measures 25 × 290 × 210 mm. The complete order number clearly separates this older connection combination from later CP versions. For replacement, complete MLFB, rack compatibility, RJ45-/AUI usage, network topology, IP or ISO configuration, communication connections and the existing STEP-7 project must be checked together. The configured connection resources, partner addresses and the communication blocks used must also match the old CP version. It must not be exchanged for newer CP-443-1 variants based solely on the function name because connection and configuration details may differ.
