The Siemens 6ES7444-1MX00-0XE0 is a SIMATIC S7-400 communication module CP 444 designed to connect an S7-400 rack to Industrial Ethernet using the MAP 3.0 protocol architecture, based on the transport protocol per ISO 8073 class 4. It communicates at up to 10 Mbit/s and connects via a 15-pin sub-D socket that supports automatic switchover between AUI and industrial twisted-pair media. The module supports S7 extended communication, drawing up to 3.1 A from the 5 V DC backplane bus, with a typical power loss of 15.6 W.
