It supports ring redundancy with integrated redundancy manager function, so a media break on the PROFINET ring does not drop the IO devices — the switchover is seamless to the controller logic. ## Backplane supply and power budget Powered from the S7-400 backplane at 5 V DC, the module draws a nominal 7.25 W — well within the rack power budget for a single-width compact module. The 5 V supply tolerance is 5 %, so the backplane power supply must hold regulation within that band; a sagging rail can cause the CP to drop IO communication without a fault code. ## Engineering tool and configuration Configuration requires STEP 7 V5.5 SP3 or higher, or STEP 7 Professional V12 (TIA Portal) or higher — the CP is not supported by older engineering versions. The module is configured via the hardware catalog in TIA Portal; the PROFINET interface name and IP address are set through the device configuration, and the IO controller assignment is made in the network view. ## Environmental tolerance for mill-floor deployment IP20 protection means it belongs in a sealed enclosure; dust and conductive debris from the mill floor will short the backplane if the cabinet door is left open.","metaTitle":"Siemens 6GK7443-1EX30-0XE1 CP 443-1, 10/100 Mbit/s","metaDescription":"Siemens 6GK7443-1EX30-0XE1 CP 443-1 PROFINET controller, 10/100 Mbit/s, max 4 IO controllers, ring redundancy, DCP/NTP/LLDP, active production, sourced to","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"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":"No","Height":"290 mm","at 5 V":"5 %","Maximum":"128; when using several CPUs","SNMP v1":"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]":"7.25 W","Ring Redundancy":"Yes","lifecycle_stage":"current","During Operation":"0 ... 60 °C","During Transport":"-40 ... +70 °C","per CPU / maximum":"14","Redundancy Manager":"Yes","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.
