Integrated protocol drivers cover Freeport, ASCII, Modbus RTU master and slave, and USS, letting the module link directly to third-party serial devices or Siemens drives without an external gateway.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSKU\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6ES7241-1CH32-0XB0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSiemens\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSeries\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSIMATIC S7-1200\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduct Designation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCM 1241 RS 422\/485\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInterface\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRS 422\/485 (X.27), 9-pin D-sub socket\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCable Length\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1,000 m max., point-to-point\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProtocol Drivers\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFreeport, ASCII, Modbus RTU master\/device, USS, 3964(R)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModbus RTU Master Devices\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e247 max.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSupply Voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e24 V DC, 20.4 ... 28.8 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCurrent Consumption\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e220 mA max., from backplane bus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePower Loss\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.1 W, typ.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProtection Class\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAmbient Temperature (Vertical)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-20 ... +50 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDimensions (W x H x D)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e30 x 100 x 75 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e155 g, approx.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eCertifications \u0026amp; Standards\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCE mark\u003c\/li\u003e\n\u003cli\u003eCSA approval\u003c\/li\u003e\n\u003cli\u003eUL approval\u003c\/li\u003e\n\u003cli\u003ecULus\u003c\/li\u003e\n\u003cli\u003eFM approval\u003c\/li\u003e\n\u003cli\u003eRCM\u003c\/li\u003e\n\u003cli\u003eKC approval\u003c\/li\u003e\n\u003cli\u003eMarine approval\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSelection Notes\u003c\/h2\u003e\u003cp\u003eRS422\/485 gives a two- or four-wire multi-drop link, so it fits Modbus RTU networks with multiple slave devices on one segment, up to 247 addresses under standard Modbus addressing (32 devices per physical segment before a repeater is needed). Where the target device only exposes an RS232 port, the RS232-only CM 1241 variant in the same family is the correct choice instead of this module. The USS protocol driver, available as a library function, lets this module talk directly to Siemens drives over serial USS without a separate PROFIBUS or PROFINET drive interface.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eSerial connection to third-party Modbus RTU devices, legacy point-to-point ASCII equipment, or Siemens drives over USS from an S7-1200 CPU that lacks a native RS422\/485 port.\u003c\/p\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":53960783298843,"sku":"6ES7241-1CH32-0XB0","price":178.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/siemens-6es7241-1ch32-0xb0-cm1241-rs422-485-comm-module.png?v=1789663479","url":"https:\/\/stoklink.com\/products\/siemens-6es7241-1ch32-0xb0-cm1241-rs422-485-comm-module","provider":"Stoklink","version":"1.0","type":"link"}
