Rated for 10 to 1000 Mbit/s on the first interface, it handles the bandwidth for both process data and IT traffic without bottlenecking the backplane. ## Routing and security posture Static IP routing is supported; dynamic routing protocols (RIPv1, RIPv2, OSPFv2, and their IPv6 equivalents) are not. The module also supports SNMP v1 and v3, LLDP, DCP, NTP, and IEEE 802.1x authentication — a full set of industrial network services for a managed PROFINET cell. The firewall runs stateful inspection, meaning it tracks connection state and blocks unsolicited traffic at the IP level, which is a step above simple packet filtering.","metaTitle":"Siemens 6GK7543-1AX00-0XE0 CP 1543-1","metaDescription":"Siemens 6GK7543-1AX00-0XE0 CP 1543-1 communications processor with stateful inspection firewall, 10-1000 Mbit/s, active production, sourced per RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLC Communication Modules"],"specifications":{"BGP":"No","DCP":"Yes","NTP":"Yes","PPP":"No","LLDP":"Yes","Note":"depending on CPU type","VRRP":"No","Depth":"129 mm","RIPv2":"No","Width":"35 mm","Height":"142 mm","OSPFv2":"No","RIP v1":"No","TCP/IP":"Yes","Maximum":"118; depending on the system upper limit","SNMP v1":"Yes","SNMP v3":"Yes","at 15 V":"3 %","Required":"STEP 7 Professional V14 (TIA Portal) or higher","PPoE via DSL":"No","Module Format":"Compact module S7-1500 single width","VRRP for IPv6":"No","ACL - IP-based":"No","During Storage":"-40 ... +70 °C","RIPnG for IPv6":"No","power loss [W]":"5.3 W","OSPFv3 for IPv6":"No","lifecycle_stage":"current","During Transport":"-40 ... +70 °C","Firewall Version":"stateful inspection","per CPU / maximum":"8","static IP routing":"Yes","dynamic IP routing":"No","protection class IP":"IP20","At The 1st Interface":"10 ... 1000 Mbit/s","IEEE 802.1x (radius)":"Yes","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. To stay informed about product updates as they occur, sign up for a product-specific newsletter. For more information, visit http://support.automation.siemens.com.
