It does not support LLDP (Link Layer Discovery Protocol), so topology discovery via network management tools like Siemens PRONETA or third-party LLDP scanners will not work on this interface — plan your asset inventory and network mapping accordingly. ## Interface, supply, and physical fit in the S7-400 rack Single Industrial Ethernet interface at 10/100 Mbit/s via an RJ45 port or AUI (15-pin Sub-D socket for 10 Mbit/s ITP) — the RJ45 handles modern plant-floor connections; the AUI port is legacy for older transceivers or fibre media converters. Powered from the S7-400 backplane at 5 VDC, drawing 1.4 A typical — no external supply needed, but the rack power budget must account for this draw plus the 8.6 W power loss the module dissipates as heat inside the enclosure. Compact single-width format (25 mm wide, 290 mm high, 210 mm deep) — fits one slot in the S7-400 rack; IP20 rated, so it belongs in a sealed cabinet, not on the plant floor. ## Active lifecycle and sourcing posture No stock-holding claim — quoted per RFQ.","metaTitle":"Siemens 6GK7443-1EX11-0XE0 CP 443-1, NTP, 10/100 Mbit/s","metaDescription":"Siemens 6GK7443-1EX11-0XE0 CP 443-1 communications processor, NTP support, 10/100 Mbit/s Industrial Ethernet, 5 VDC from backplane, 8.6 W.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLC Communication Modules"],"specifications":{"NTP":"Yes","LLDP":"No","Depth":"210 mm","Width":"25 mm","title":"6GK7443-1EX11-0XE0","C-PLUG":"No","Height":"290 mm","at 5 V":"5 %","Maximum":"48","SNMP v1":"No","Required":"STEP 7 V5.1 SP2 or higher","description":"********** spare part ********* communications processor CP 443-1 for connection of SIMATIC S7-400 to industrial Ethernet via ISO/TCP/IP and UDP, S7 communication, fetch/write, diagnostics extensions, send/receive, with and without RFC1006, multicast, NTP, initialization via LAN, access protection via IP access list 10/100 Mbit.","Module Format":"Compact module S7-400 single width","ACL - IP-based":"No","During Storage":"-40 ... +70 °C","Supply Voltage":"5 V","power loss [W]":"8.6 W","Ring Redundancy":"No","lifecycle_stage":"current","During Operation":"0 ... 60 °C","During Transport":"-40 ... +70 °C","per CPU / maximum":"14","protection class IP":"IP20","At The 1st Interface":"10 ... 100 Mbit/s","Security Information":"Siemens provides products and solutions with industrial security functions that support the secure operation of plants, solutions, machines, equipment and/or networks. They are important components in a holistic industrial security concept. With this in mind, Siemens’ products and solutions undergo continuous development. Siemens recommends strongly that you regularly check for product updates. For the secure operation of Siemens products and solutions, it is necessary to take suitable preventive action(e.g. cell protection concept) and integrate each component into a holistic, state-of-the-art industrial security concept. Third-party products that may be in use should also be considered. For more information about industrial security, visit http://www.siemens.com/industrialsecurity.
