The hardware functions as a single-slot network master that interfaces the primary controller backplane directly with a multidrop serial bus circuit. It translates host processor register instructions into differential Genius network frames, enabling synchronous transmission loops with distributed I\/O blocks and peripheral processing units.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\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\u003eIC697BEM731Z\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGE Fanuc (Emerson Automation)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUnited States\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.62 kg (1.37 lbs) total pack mass \/ 0.45 kg (1.00 lbs) net board\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e4.0 cm x 22.5 cm x 29.2 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e5.0 V DC @ 1.3 A drawn from the backplane bus rails\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eGenius I\/O Bus Controller\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Frame\u003c\/td\u003e\n\u003ctd\u003eSeries 90-70 PLC Chassis (Single slot width)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSerial Interfaces\u003c\/td\u003e\n\u003ctd\u003e1 x Genius Bus channel \/ 1 x Hand-Held Terminal (HHT) connection port\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNetwork Baud Rates\u003c\/td\u003e\n\u003ctd\u003e153.5 kbps standard\/extended, 76.8 kbps, or 38.4 kbps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBus Media Specification\u003c\/td\u003e\n\u003ctd\u003eBelden 9182 type shielded twinaxial cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Line Span\u003c\/td\u003e\n\u003ctd\u003e2000 to 7500 ft (dependent on configured data transmission rate)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBus Termination Value\u003c\/td\u003e\n\u003ctd\u003e75 Ohm or 150 Ohm resistors mounted at both physical end nodes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNode Capacity Scale\u003c\/td\u003e\n\u003ctd\u003eUp to 30 active network devices per bus channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBase Connections\u003c\/td\u003e\n\u003ctd\u003e3PL and 1PL mechanical terminal port segments\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVisual Indicators\u003c\/td\u003e\n\u003ctd\u003e3 x front panel diagnostic status LEDs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFirmware Flash Compatibility and I\/O Density Scaling\u003c\/h3\u003e\n\u003cp\u003eThe GE Fanuc IC697BEM731Z executes data frame routing using a localized communications engine that preserves steady cycle times regardless of network traffic changes. The module requires specific firmware flash compatibility alignment with the host Series 90-70 CPU operating system to ensure data packet transmission across the backplane structure.\u003c\/p\u003e\n\u003cp\u003eThe serial configuration allows for structured I\/O density scaling profiles by mapping 30 separate distributed device images into the central controller's memory tables. The internal processing network arbitrates messaging priorities, allowing alarm blocks and safety word matrices to transfer without affecting standard binary I\/O scan routines.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the IC697BEM731Z bus controller support live insertion or hot-swapping into an active Series 90-70 chassis?\u003c\/p\u003e\n\u003cp\u003eA: No. The Series 90-70 backplane architecture requires full power de-energization prior to module installation or removal. Inserting or pulling this card while the 5.0 V DC rack power line is active can cause bus transceiver degradation, register corruption, or system shutdown faults.\u003c\/p\u003e\n\u003cp\u003eQ: How do changing baud rate selections alter the maximum allowable network distance constraints?\u003c\/p\u003e\n\u003cp\u003eA: High-frequency data loops require shorter signal runs to control attenuation. Selecting the 153.5 kbps rate restricts total network line runs to 2000 ft, whereas reducing the transport cycle down to 38.4 kbps extends the maximum line span up to 7500 ft over specified Belden 9182 cabling.\u003c\/p\u003e\n\u003cp\u003eQ: What action must be taken regarding the built-in Hand-Held Terminal port during normal production scans?\u003c\/p\u003e\n\u003cp\u003eA: The Hand-Held Terminal (HHT) port remains passive during normal operations and does not require an active configuration link. It functions as a local point for technicians to connect monitor tools for line diagnostics or device parameter updates without breaking the primary serial network.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eShut down all primary power switches supplying the controller rack frame and external field distribution loops before positioning the hardware.\u003c\/li\u003e\n\u003cli\u003eAlign the board with the assigned slot channel tracks inside the Series 90-70 chassis, pushing firmly inward until the rear 3PL and 1PL connectors seat completely.\u003c\/li\u003e\n\u003cli\u003eTighten the top and bottom mechanical lock fasteners to secure the faceplate and establish a solid low-impedance ground connection with the chassis rail.\u003c\/li\u003e\n\u003cli\u003eVerify that terminal nodes located at the opposite physical ends of the twinaxial trunk cable have 75 Ohm or 150 Ohm termination resistors wired across the signal lines.\u003c\/li\u003e\n\u003cli\u003eMaintain a minimum physical separation path of 30 cm between the network twinaxial cable runs and adjacent high-current AC mains, motor circuits, or drive supply loops.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GE Fanuc","offers":[{"title":"Default Title","offer_id":44233472802915,"sku":"IC697BEM731Z","price":420.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0583\/5246\/8067\/files\/25._bd04da32-4a36-4d76-96c3-de057d94a867.jpg?v=1780469047","url":"https:\/\/www.autocontrolglobal.com\/products\/ic697bem731z-ge-fanuc-series-90-70-module-datasheet-technical-manual","provider":"AutoControl Global","version":"1.0","type":"link"}
