It occupies a single-width slot in the rack and handles PROFINET IO communication for up to 4 IO controllers per module, with a maximum of 14 PROFINET IO devices per CPU when using multiple CPUs. The first interface runs at 10 to 1000 Mbit/s, the second at 10 to 100 Mbit/s. The integrated 2-port switch supports ring redundancy with a redundancy manager, so the module can be wired into a ring topology without an external switch. ## Security and network services onboard A stateful inspection firewall is built in, with IP-based ACLs for both general traffic and PLC/routing access. SNMP v1 and v3 are supported for network management, along with DCP, NTP, and LLDP for device discovery and time synchronisation. The module includes a C-PLUG slot for removable configuration storage, 16 Mibyte of RAM, and 30 Mibyte of flash memory file system. Power dissipation is 9 W, and the IP20 housing is sized for the standard S7-400 enclosure.","metaTitle":"Siemens 6GK7443-1GX30-0XE0 CP 443-1 Advanced","metaDescription":"Siemens CP 443-1 Advanced 6GK7443-1GX30-0XE0, PROFINET IO controller for S7-400, 2-port switch, stateful inspection firewall, ring redundancy.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["PLC Communication Modules"],"specifications":{"DCP":"Yes","NTP":"Yes","LLDP":"Yes","Note":"max. 4 as PN IO ctrl.","Depth":"210 mm","Width":"25 mm","C-PLUG":"Yes","Height":"290 mm","as RAM":"16 Mibyte","at 5 V":"5 %","Maximum":"128; when using several CPUs","SNMP v1":"Yes","SNMP v3":"Yes","Required":"STEP 7 V5.5 SP3 or higher / STEP 7 Professional V12 (TIA Portal) or higher","Module Format":"Compact module S7-400 single width","ACL - IP-based":"Yes","During Storage":"-40 ... +70 °C","Switch-Managed":"No","power loss [W]":"9 W","Ring Redundancy":"Yes","lifecycle_stage":"current","During Operation":"0 ... 60 °C","During Transport":"-40 ... +70 °C","Firewall Version":"stateful inspection","per CPU / maximum":"14","Redundancy Manager":"Yes","protection class IP":"IP20","At The 1st Interface":"10 ... 1000 Mbit/s","At The 2nd 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.
