Full specifications and sourcing options are below.","salesMarkdown":"## Overview The module draws 5.0 W from a 24 V DC supply and is rated IP20 for in-cabinet use. Its 9-pin Sub-D socket provides the RS485 PROFIBUS interface. ## Applications This communications processor is used in SIMATIC S7-300-based automation systems where the controller must participate in a PROFIBUS network as an FMS or S7 communication node. Typical installations include process plants, material handling systems, and machine cells that use PROFIBUS for distributed I/O, drives, and operator panels. The module occupies a single slot in the S7-300 DIN-rail mounting rack. Its dimensions are 40 mm wide, 125 mm high, and 120 mm deep, with a weight of 300 g. The IP20 rating means it must be installed inside a cabinet with a minimum protection enclosure. Supply is 24 V DC via the backplane bus; no separate power connection is needed. The 9-pin Sub-D connector faces the front of the module, accessible after the front panel is opened. The 6GK7343-5FA01-0XE0 is a Siemens-branded product. No official lifecycle status (active, phase-out, or discontinued) is provided in the available data. For sourcing, request a firm quote to confirm current availability and lead time.","metaTitle":"Siemens 6GK7343-5FA01-0XE0 CP 343-5 PROFIBUS Communications Processor","metaDescription":"Siemens CP 343-5 (6GK7343-5FA01-0XE0) communications processor for SIMATIC S7-300, PROFIBUS FMS, 12 Mbit/s, 24 V DC, IP20, single-width.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLC Communication Modules"],"specifications":{"Depth":"120 mm","Width":"40 mm","Height":"125 mm","TCP/IP":"No","Maximum":"16","Required":"STEP 7 V5.1 SP3 or higher and NCM S7 for PROFIBUS","Module Format":"Compact module S7-300 single width","During Storage":"-40 ... +70 °C","Supply Voltage":"24 V","power loss [W]":"5 W","lifecycle_stage":"current","During Operation":"0 ... 60 °C","During Transport":"-40 ... +70 °C","For Power Supply":"4-pole terminal block","per CPU / maximum":"4","protection class IP":"IP20","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.
