It brings a single Industrial Ethernet interface running at 10 to 100 Mbit/s via an RJ45 port or AUI connector, so the CPU can talk to higher-level systems, HMIs, or other controllers over TCP/IP without loading the CPU's own backplane bandwidth. Power comes from both the 5 V backplane bus (drawing 0.07 A typical) and an external 24 V DC supply through a 2-pole pluggable terminal block. This module supports NTP time synchronization, so it can act as a time slave on the plant network and pass that time to the CPU — useful for aligning event logs across multiple controllers. It also supports SICLOCK for higher-accuracy time-stamping if your application needs it. It does NOT support DCP (Discovery and Configuration Protocol), which means you cannot assign the IP address via DCP broadcast from a PG/PC — you will need to set the address through the CPU's configuration or via STEP 7 hardware config. Similarly, LLDP is not supported, so network topology discovery via PROFINET is not available on this module. The module handles up to 32 active connections in multi-protocol mode and supports up to 16 multicast stations. For most line-level applications connecting to one or two HMIs and a SCADA server, that is ample headroom. Operating temperature range is 0 to 60 °C horizontally mounted, or 0 to 40 °C vertically installed. The module requires STEP 7 V5.1 SP2 or higher for configuration. If your engineering station is running an older version, you will need to update before you can add this module to the hardware catalog.","metaTitle":"Siemens 6GK7343-1EX11-0XE0 CP 343-1, Industrial Ethernet","metaDescription":"Siemens 6GK7343-1EX11-0XE0 CP 343-1 communications processor, Industrial Ethernet interface, NTP support, active production, quoted to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLC Communication Modules"],"specifications":{"DCP":"No","NTP":"Yes","LLDP":"No","Depth":"120 mm","Width":"80 mm","Height":"125 mm","TCP/IP":"Yes","at 5 V":"5 %","Maximum":"16","SNMP v1":"No","at 24 V":"5 %","Required":"STEP 7 V5.1 SP2 or higher","Module Format":"Compact module S7-300 double width","During Storage":"-40 ... +70 °C","power loss [W]":"10 W","Ring Redundancy":"No","lifecycle_stage":"current","During Transport":"-40 ... +70 °C","For Power Supply":"2-pole plugable terminal block","protection class IP":"IP20","At The 1st Interface":"10 ... 100 Mbit/s","S7-300 rail mounting":"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.
