Its low-impedance Wye topology ensures minimal signal distortion and delay when daisy-chaining baseplates across extended rack layouts. Maintaining proper signal integrity prevents bit errors and maintains high-speed scan synchronism across all local expansion and remote baseplates, preserving firmware flash compatibility and predictable scan execution.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What happens if the unused female connector on the final expansion rack is left unterminated?\u003c\/p\u003e\n\u003cp\u003eA: An unterminated expansion bus causes high-frequency signal reflections, leading to erratic communication, intermittent parity errors, and potential loss of remote I\/O data scan synchronization. An IC693ACC307 terminator plug must be installed on the open female port.\u003c\/p\u003e\n\u003cp\u003eQ: How many IC693CBL301 cables can be daisy-chained in a single system?\u003c\/p\u003e\n\u003cp\u003eA: Systems using CPU models 350 through 364 support up to 7 expansion cables (maximum aggregate length of 50 feet for expansion baseplates or 700 feet for remote baseplates). Systems using CPU models 331 through 341 support up to 4 expansion cables.\u003c\/p\u003e\n\u003cp\u003eQ: Can the IC693CBL301 bus expansion cable be plugged or unplugged while the PLC is powered?\u003c\/p\u003e\n\u003cp\u003eA: Removal and insertion of expansion bus cables under power is not recommended, as interrupting backplane bus continuity during an active scan cycle triggers immediate CPU system faults.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eRemove electrical power from the CPU baseplate and all secondary expansion or remote baseplates before installing or reconfiguring bus cables.\u003c\/li\u003e\n\u003cli\u003eAttach the single 25-pin male D-sub connector on the first cable to the female expansion port located on the far right side of the main CPU baseplate.\u003c\/li\u003e\n\u003cli\u003eRoute the 2-meter shielded cable through dedicated low-voltage wiring troughs, isolating it from AC power lines and motor drive wiring.\u003c\/li\u003e\n\u003cli\u003ePlug the male connector of the dual-headed Wye end into the female bus port on the left side of the adjacent expansion baseplate, tightening all connector thumbscrews to ensure frame ground contact.\u003c\/li\u003e\n\u003cli\u003eAttach the next IC693CBL301 cable to the remaining female port to continue daisy-chaining, or insert an IC693ACC307 terminator plug into the open female socket on the last rack in the chain.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"GE Fanuc","offers":[{"title":"Default Title","offer_id":43778213904474,"sku":"IC693CBL301","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/IC693CBL301.png?v=1785729548","url":"https:\/\/www.spareoil.com\/ar\/products\/ge-fanuc-ic693cbl301-series-90-30-i-o-bus-expansion-cable","provider":"SpareOil Automation","version":"1.0","type":"link"}
