Operating across deterministic networks, the module handles full-duplex and half-duplex DF1 conversions without placing computational overhead on the CPU scan cycle. Onboard firmware features adjustable baud rates, node addressing, and error-checking algorithms (CRC\/LRC) to preserve message integrity in electrically noisy industrial environments.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 1747-KE module be used to connect a modem for remote dial-up monitoring of an SLC 500 processor?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the 1747-KE module supports DF1 half-duplex modem master\/slave configurations, allowing remote supervisory software to dial into the SLC 500 network.\u003c\/p\u003e\n\u003cp\u003eQ: What is the purpose of the third dedicated configuration port on the module?\u003c\/p\u003e\n\u003cp\u003eA: The configuration port allows engineers to connect a terminal or PC running terminal emulation software to set operating parameters, communication speeds, and protocol modes independently of the active runtime serial channels.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChassis Slot Insertion\u003c\/strong\u003e: Insert the 1747-KE module into any available local I\/O slot in an SLC 500 chassis (excluding slot 0). Slide the module firmly along the slot guides until top and bottom chassis latches snap securely into place.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSerial Cable Shielding \u0026amp; Routing\u003c\/strong\u003e: Use shielded twisted-pair cables for DH-485 and DF1 RS-232 serial connections. Route signal wiring in dedicated grounded wireways isolated from high-voltage motor conductors and AC power lines to avoid EMI cross-talk.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrounding \u0026amp; Surge Suppression\u003c\/strong\u003e: Ensure the SLC 500 chassis frame is connected to the master enclosure earth ground bar via a low-impedance copper strap. Terminate serial cable shields at a single ground reference point to prevent ground loop currents across communication nodes.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":52689187373336,"sku":"1747-KE","price":270.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/1747-KE_Cocoai.jpg?v=1789545006","url":"https:\/\/www.innoplcsync.com\/products\/allen-bradley-1747-ke-communication-interface-module","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
