It carries DCP, NTP, and LLDP protocols out of the box — DCP auto-assigns IP addresses, NTP synchronizes clocks across the network, and LLDP feeds topology detection for PROFINET. The module draws 0.2 A typical at 5 V from the backplane bus, and requires an external 24 V DC supply via a 2-pole pluggable terminal block. ACL filtering (IP-based) and SNMP v1 management are included; the module also supports SICLOCK for high-accuracy time and can switch off non-required services. Rated for ambient operation from -25 to +70 °C; storage and transport down to -40 °C. ## Sourcing posture The 6AG1343-1EX30-7XE0 can be specified into new BOMs with confidence. We source it upon RFQ; no lead-time concern for a production-active Siemens CP.","metaTitle":"Siemens 6AG1343-1EX30-7XE0 CP, DCP, NTP, LLDP, Ring","metaDescription":"Siemens S7-300 PROFINET IO compact module, active production, supports DCP, NTP, LLDP, SNMP v1, ring redundancy, IRT, 10/100 Mbit/s. 40x125x120 mm, 24V DC, IP20.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLCs (Programmable Logic Controllers)"],"specifications":{"DCP":"Yes","NTP":"Yes","LLDP":"Yes","Depth":"120 mm","Width":"40 mm","title":"6AG1343-1EX30-7XE0","Height":"125 mm","Maximum":"16","SNMP v1":"Yes","Required":"STEP 7 V5.4 SP2 or higher","description":"SIPLUS NET CP 343-1 based on 6GK7343-1EX30-0XE0 with conformal coating, -25…+70 °C, communications processor for connection of SIMATIC S7-300 to Industrial Ethernet via ISO and TCP/IP, PROFINET IO controller or PROFINET IO device, integrated 2-port switch ERTEC 200 S7 communication, fetch/write, send/receive with and without RFC1006, multicast DHCP, NTC-CPU sync, diagnostics, initialization via LAN,","Module Format":"Compact module S7-300 single width","ACL - IP-based":"Yes","During Storage":"-40 ... +70 °C","Supply Voltage":"24 V","power loss [W]":"5.8 W","Ring Redundancy":"Yes","lifecycle_stage":"current","During Operation":"-25 ... +70 °C","During Transport":"-40 ... +70 °C","For Power Supply":"2-pole plugable terminal block","Redundancy Manager":"No","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.
