This hardware unit equips industrial setups with two independent isolated serial ports, facilitating reliable multi-protocol data exchange, peripheral device integration, and expanded network connectivity in demanding plant floor environments.\u003c\/p\u003e\n\u003ch3\u003eSerial Ports and Communication Capabilities\u003c\/h3\u003e\n\u003cp\u003eThe module features two independent serial ports supporting data rates from 300 bit\/s to 19.2 kbit\/s. Port 1 provides an RS-232 interface via a 15-pin D-sub connector, while Port 2 offers selectable RS-232 or RS-485 connections. Supported communication protocols include SNP, SNP-X, RTU, and CCITT #16.\u003c\/p\u003e\n\u003ch3\u003eBuffer Management and Power Architecture\u003c\/h3\u003e\n\u003cp\u003eAn integrated 4 KB RAM buffer handles transmit and receive queues independently without interrupting the primary PLC scan cycle. A built-in 220 µF energy storage capacitor maintains buffer data during brief power drops. The module draws 280 mA typical current solely from the backplane 5 V DC supply and features 500 V AC port isolation.\u003c\/p\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eIC693CMM311F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGE Fanuc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eSeries 90-30\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eCommunications Control Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Ports\u003c\/td\u003e\n\u003ctd\u003e2 isolated serial ports\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePort 1 Interface\u003c\/td\u003e\n\u003ctd\u003eRS-232 (15-pin D-sub)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePort 2 Interface\u003c\/td\u003e\n\u003ctd\u003eRS-232 or RS-485 (selectable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData Rate Range\u003c\/td\u003e\n\u003ctd\u003e300 bit\/s to 19.2 kbit\/s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported Protocols\u003c\/td\u003e\n\u003ctd\u003eSNP, SNP-X, RTU, CCITT #16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInternal Buffer\u003c\/td\u003e\n\u003ctd\u003e4 KB RAM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Cable Length\u003c\/td\u003e\n\u003ctd\u003e15 meters (RS-232), 1200 meters (RS-485)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply\u003c\/td\u003e\n\u003ctd\u003e5 V DC from backplane\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Draw\u003c\/td\u003e\n\u003ctd\u003e280 mA typical\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation Voltage\u003c\/td\u003e\n\u003ctd\u003e500 V AC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0°C to 60°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHumidity Tolerance\u003c\/td\u003e\n\u003ctd\u003e5% to 95% non-condensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e115 mm x 32 mm x 140 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.22 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: Can Port 2 on the IC693CMM311F be configured for long-distance networking? A: Yes, Port 2 supports a selectable RS-485 interface capable of communication distances up to 1200 meters.\u003c\/p\u003e\n\u003cp\u003eQ: What happens to transmission queues during a brief power interruption? A: The built-in 220 µF energy storage capacitor retains the 4 KB buffer contents to prevent data loss during momentary brownouts.\u003c\/p\u003e\n\u003cp\u003eQ: Does the module require an external power supply connection? A: No, the unit operates entirely on 5 V DC power drawn directly from the Series 90-30 system backplane.\u003c\/p\u003e","brand":"GE","offers":[{"title":"Default Title","offer_id":66983818166387,"sku":"IC693CMM311F","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/IC693MDL752D2_Cocoai_97f7c115-5cd9-4a76-98e4-5b714734531d.jpg?v=1792742395","url":"https:\/\/www.dcssupplier.com\/products\/communications-control-module-ge-ic693cmm311f","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
