The subsystem interface framework actively supports Modbus, FA-M3, MELSEC, YFGW, DARWIN\/DAQSTATION, and PLC-5\/SLC500 communication protocols.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeterministic Backplane Bus Ingestion\u003c\/strong\u003e The module mounts directly into standard Yokogawa node units and field control units, including ANB10, ANB11, ANR10, AFF50, AFV10, AFV30, and AFV40 chassis. It captures external device registers and injects the processed data packets into the high-speed controller backplane bus within a fixed, predictable processing window.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandardized Ethernet Physical Layer Execution\u003c\/strong\u003e Operating on an IEEE802.3 10BASE-T physical layer, the network controller utilizes standard CSMA\/CD media access protocols. It routes data packets over 100 ohm unshielded twisted-pair (UTP) copper cabling across a maximum structural segment length of 100 m between the field control station or network hub and the peripheral subsystems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the ALE111-S00 port be forced to operate in Full-Duplex mode to match modern network switches?\u003c\/p\u003e\n\u003cp\u003eA: No. The ALE111-S00 hardware layer is strictly restricted to Half-Duplex transmission at a fixed speed of 10 Mbps. Connecting the module to an external switch requires setting the corresponding switch port to auto-negotiation or forcing it to 10 Mbps Half-Duplex to prevent duplex mismatch errors and packet collisions.\u003c\/p\u003e\n\u003cp\u003eQ: What happens to the controller data registers if the RJ-45 communication link fails?\u003c\/p\u003e\n\u003cp\u003eA: Upon loss of the physical Ethernet link or communication timeout, the module triggers an internal diagnostic fault bit across the backplane bus. The hosting Yokogawa field control station intercepts this flag and updates the associated data registers to a \"Bad\" status, allowing the control logic to execute fallback safety procedures.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":47618534375614,"sku":"ALE111-S00","price":3000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-06-10_11-38-36_26f8bfba-c826-408f-ab1d-331724dd7660.png?v=1781070434","url":"https:\/\/www.autooiltech.com\/ar\/products\/yokogawa-ale111-s00-ethernet-communication-module","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
