The hardware establishes real-time closed-loop position and velocity synchronization for up to 8 axes over a single fiber-optic SERCOS interface ring operating at 4-8 Mbps data rates. The optical fiber medium eliminates electrical ground loops and high-frequency electromagnetic noise susceptibility between the central controller rack and distributed field drives, parsing interpolated motion commands with sub-millisecond execution cycles.\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\u003e1756-M08SE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley \/ Rockwell Automation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.51 lbs (0.23 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eControlLogix Single-Slot Standard Module\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 W (Backplane: 760 mA at 5.1 VDC, 2.5 mA at 24 VDC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Axes\u003c\/td\u003e\n\u003ctd\u003e8 Axes \/ Drives\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Medium\u003c\/td\u003e\n\u003ctd\u003eSingle Fiber Optic (SERCOS Ring)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData Transfer Speed\u003c\/td\u003e\n\u003ctd\u003e4-8 Mbps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConfiguration Software\u003c\/td\u003e\n\u003ctd\u003eStudio 5000 Logix Designer \/ ControlLogix\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eControlLogix System Architecture \u0026amp; Backplane Protocol Features\u003c\/h3\u003e\n\u003cp\u003eThe module communicates over the local ControlLogix backplane bus utilizing high-velocity CIP (Common Industrial Protocol) framing. Backplane bus communication velocity guarantees low deterministic latency during multi-axis position trajectory updates. High-density I\/O routing protocols ensure synchronous cyclic motion data transmission to the host controller, matching system-configured Requested Packet Interval (RPI) rates down to strict motion cycle limits. Firmware flash compatibility enables online updates through Studio 5000 Logix Designer without dismounting physical chassis hardware.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 1756-M08SE module be removed or inserted under power (RIUP)?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the module supports Removal and Insertion Under Power (RIUP) within a powered ControlLogix chassis. However, breaking the active fiber-optic SERCOS ring while drives are in motion will cause an immediate ring topology break fault and trigger safety drive-stop routines across all connected 8 axes.\u003c\/p\u003e\n\u003cp\u003eQ: How do fiber-optic bending radius limits impact field signal integrity on the 1756-M08SE ring?\u003c\/p\u003e\n\u003cp\u003eA: Exceeding the minimum specified bending radius of the fiber-optic cable causes optical signal attenuation and packet loss, leading to SERCOS communication ring errors, dropped motion frames, or full ring initialization failures at 8 Mbps transmission speeds.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eVerify backplane chassis grounding complies with IEEE 1100 standards; maintain a dedicated low-impedance copper ground connection from the chassis frame to the main enclosure star ground point.\u003c\/li\u003e\n\u003cli\u003eClean all fiber-optic cable connectors with lint-free optical wipes before insertion into the module's transceiver ports to prevent dust contamination and light loss.\u003c\/li\u003e\n\u003cli\u003eMaintain a minimum cable bending radius of 30 mm (1.2 inches) during cable tray routing to avoid physical micro-fractures in the optical glass\/plastic fiber core.\u003c\/li\u003e\n\u003cli\u003eRoute fiber-optic communication lines along structured cable pathways away from high-current motor lead conduits to protect physical cable jackets from mechanical abrasion.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":48786280054974,"sku":"1756-M08SE","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/1756-M08SE_2.png?v=1787710341","url":"https:\/\/www.autooiltech.com\/products\/allen-bradley-1756-m08se-controllogix-motion-interface-module","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
