BUS cables, also referred to as industrial fieldbus cables or industrial ethernet cables, are specifically designed for high-speed data transmission in automation and process control applications. Unlike standard data cables, BUS cables are engineered to meet the stringent electrical and physical requirements of industrial communication protocols including Profibus, Profinet, DeviceNet, KNX/EIB, and CAN BUS. These cables form the nervous system of modern industrial plants, connecting PLCs (Programmable Logic Controllers), sensors, actuators, and HMIs (Human-Machine Interfaces) in a reliable, deterministic communication network. The term “BUS” derives from the Latin “omnibus” (for all), reflecting the shared communication pathway that allows multiple devices to communicate over a single cable infrastructure.

ESLos cables BUS, también conocidos como cables de bus de campo industrial o cables ethernet industriales, están diseñados específicamente para la transmisión de datos de alta velocidad en aplicaciones de automatización y control de procesos.

繁中BUS 電纜，也稱為工業現場總線電纜或工業以太網電纜，專為自動化和過程控制應用中的高速數據傳輸而設計。與標準數據電纜不同，BUS 電纜經過工程設計以滿足工業通信協議的嚴格電氣和物理要求，包括 Profibus、Profinet、DeviceNet、KNX/EIB 和 CAN BUS。這些電纜構成了現代工業工廠的神經系統，將 PLC（可編程邏輯控制器）、傳感器、執行器和 HMI（人機界面）連接在可靠、確定性的通信網絡中。”BUS” 一詞源自拉丁語 “omnibus”（對所有人），反映了允許多個設備通過單一電纜基礎設施通信的共享通信路徑。【說明：BUS 電纜必須滿足特定的阻抗、電容和衰減要求，以確保可靠的數據傳輸。使用不符合規格的電纜會導致通信錯誤、設備故障甚至整個系統停機】

Industrial BUS cables must meet demanding requirements for electromagnetic compatibility (EMC), characteristic impedance, and signal integrity. They typically feature twisted pair construction with individual and overall shielding (foil and braid) to reject electromagnetic interference from motors, variable frequency drives, and other industrial equipment. Cable performance is critical—the characteristic impedance must match the protocol specification (typically 100-150Ω for data pairs), and capacitance must be controlled to prevent signal degradation. Many BUS cables are available with LSZH (Low Smoke Zero Halogen) or FRNC (Flame Retardant Non-Corrosive) sheathing for enhanced fire safety in enclosed industrial environments.

ESLos cables BUS industriales deben cumplir con requisitos exigentes de compatibilidad electromagnética (EMC), impedancia característica e integridad de señal.

繁中工業 BUS 電纜必須滿足電磁兼容性（EMC）、特性阻抗和信號完整性的嚴格要求。它們通常採用雙絞線結構，帶有單獨和整體屏蔽（箔片和編織）以抑制電機、變頻驅動器和其他工業設備的電磁干擾。電纜性能至關重要——特性阻抗必須與協議規格匹配（數據對通常為 100-150Ω），電容必須受到控制以防止信號衰減。許多 BUS 電纜提供 LSZH（低煙無鹵）或 FRNC（阻燃非腐蝕性）護套，以在封閉的工業環境中增強防火安全性。【說明：特性阻抗匹配對於防止信號反射至關重要。阻抗不匹配會導致數據包丟失、重傳增加和通信延遲，這在實時控制系統中是不可接受的】

Profibus (Process Field Bus) is one of the most widely deployed industrial fieldbus protocols, developed by Siemens and standardized under IEC 61158 and EN 50170. The protocol operates in two primary variants: Profibus DP (Decentralized Peripherals) for high-speed communication with PLCs and distributed I/O modules at up to 12 Mbit/s, and Profibus PA (Process Automation) for intrinsically safe communication in hazardous areas at 31.25 kbit/s. Profibus DP cables use RS-485 signaling with specific impedance requirements (150Ω ±15%), while Profibus PA uses Manchester Bus Powered (MBP) signaling that provides both power and data over a single twisted pair. The “FC (Fast Connect)” designation indicates cables designed for rapid field termination using insulation-displacement connectors.

ESProfibus (Process Field Bus) es uno de los protocolos de bus de campo industrial más ampliamente implementados, desarrollado por Siemens y estandarizado bajo IEC 61158.

繁中Profibus（過程現場總線）是部署最廣泛的工業現場總線協議之一，由西門子開發並在 IEC 61158 和 EN 50170 下標準化。該協議以兩種主要變體運行：Profibus DP（分散式外圍設備）用於與 PLC 和分佈式 I/O 模塊進行高達 12 Mbit/s 的高速通信，Profibus PA（過程自動化）用於危險區域以 31.25 kbit/s 進行本質安全通信。Profibus DP 電纜使用 RS-485 信號傳輸，具有特定的阻抗要求（150Ω ±15%），而 Profibus PA 使用曼徹斯特總線供電（MBP）信號傳輸，通過單個雙絞線提供電源和數據。”FC（快速連接）” 標識表示設計用於使用絕緣位移連接器進行快速現場端接的電纜。【說明：Profibus DP 和 PA 的關鍵區別在於 DP 用於高速、非危險區域的自動化，而 PA 專為危險環境設計，提供本質安全特性。PA 電纜必須符合 FISCO（現場總線本質安全概念）模型】

Profinet (Process Field Net) is the Industrial Ethernet standard developed by Profibus International (now PI – Profibus & Profinet International), standardized under IEC 61158 and IEC 61784. Unlike traditional fieldbus protocols, Profinet operates over standard Ethernet infrastructure at 100 Mbit/s or 1 Gbit/s, enabling seamless integration with IT systems while providing deterministic real-time performance required for motion control applications. Profinet cables are categorized by installation environment: Type A for fixed installations in control cabinets and cable trays, typically with LSZH sheathing; and Type B for flexible applications with PUR (Polyurethane) sheathing that offers superior resistance to oils, chemicals, and mechanical stress. Both types use standard Cat 5e construction with 100Ω impedance.

ESProfinet (Process Field Net) es el estándar de Ethernet Industrial desarrollado por Profibus International, estandarizado bajo IEC 61158 e IEC 61784.

繁中Profinet（過程現場網）是由 Profibus International（現為 PI – Profibus & Profinet International）開發的工業以太網標準，在 IEC 61158 和 IEC 61784 下標準化。與傳統現場總線協議不同，Profinet 在標準以太網基礎設施上以 100 Mbit/s 或 1 Gbit/s 運行，實現與 IT 系統的無縫集成，同時提供運動控制應用所需的確定性實時性能。Profinet 電纜按安裝環境分類：Type A 用於控制櫃和電纜托架中的固定安裝，通常採用 LSZH 護套；Type B 用於柔性應用，採用 PUR（聚氨酯）護套，對油、化學品和機械應力具有優越的抵抗力。兩種類型都使用標準 Cat 5e 結構，阻抗為 100Ω。【說明：Profinet 相對於傳統現場總線的主要優勢是更高的帶寬、與標準 IT 設備的兼容性，以及通過 IRT（等時實時）實現確定性通信的能力，週期時間可低至 31.25 微秒】

DeviceNet is a CAN (Controller Area Network) based industrial protocol developed by Allen-Bradley (now Rockwell Automation) and standardized under IEC 62026 and EN 50325. A unique feature of DeviceNet is that it combines both data and power in a single cable, with a data pair (CAN_H and CAN_L) for communication and a separate power pair (V+ and V-) for device power. This eliminates the need for separate power wiring to field devices. DeviceNet cables come in two variants: Thin cables (also called “drop cables”) for connecting individual devices to the network, and Thick cables (also called “trunk cables”) for the main backbone with higher current capacity. The protocol operates at 125 kbit/s, 250 kbit/s, or 500 kbit/s depending on network length.

ESDeviceNet es un protocolo industrial basado en CAN (Controller Area Network) desarrollado por Allen-Bradley y estandarizado bajo IEC 62026.

繁中DeviceNet 是基於 CAN（控制器區域網絡）的工業協議，由 Allen-Bradley（現為 Rockwell Automation）開發，並在 IEC 62026 和 EN 50325 下標準化。DeviceNet 的一個獨特特徵是它將數據和電源組合在單根電纜中，數據對（CAN_H 和 CAN_L）用於通信，獨立的電源對（V+ 和 V-）用於設備供電。這消除了對現場設備單獨電源佈線的需求。DeviceNet 電纜有兩種變體：細電纜（也稱為 “分支電纜”）用於將單個設備連接到網絡，粗電纜（也稱為 “幹線電纜”）用於具有更高電流容量的主幹線。根據網絡長度，協議以 125 kbit/s、250 kbit/s 或 500 kbit/s 運行。【說明：DeviceNet Thin 和 Thick 電纜不可互換使用——Thick 電纜僅用於主幹線，而 Thin 電纜用於從主幹線到設備的分支連接。混合使用會導致阻抗不匹配和通信故障】

KNX (Konnex), formerly known as EIB (European Installation Bus), is the worldwide standard for building automation, standardized under ISO/IEC 14543-3. KNX integrates lighting, HVAC (heating, ventilation, air conditioning), blinds, security systems, and other building services into a unified control network. The protocol was developed by the KNX Association (formed from the merger of EIB, BatiBUS, and EHS associations) and is particularly popular in European “green building” and smart building installations. KNX/EIB cables use a simple twisted pair construction for data transmission at 9.6 kbit/s, with the bus providing 29V DC power to devices. Cables are typically FRNC-LSZH (Flame Retardant Non-Corrosive, Low Smoke Zero Halogen) sheathed for compliance with building fire safety regulations.

繁中KNX（Konnex），前身為 EIB（歐洲安裝總線），是建築自動化的全球標準，在 ISO/IEC 14543-3 下標準化。KNX 將照明、HVAC（暖通空調）、窗簾、安全系統和其他建築服務集成到統一的控制網絡中。該協議由 KNX 協會（由 EIB、BatiBUS 和 EHS 協會合併而成）開發，在歐洲 “綠色建築” 和智能建築安裝中特別受歡迎。KNX/EIB 電纜使用簡單的雙絞線結構，以 9.6 kbit/s 進行數據傳輸，總線為設備提供 29V DC 電源。電纜通常採用 FRNC-LSZH（阻燃非腐蝕性、低煙無鹵）護套，以符合建築防火安全法規。【說明：KNX 是一個開放標準，這意味著不同製造商的設備可以互操作。這與許多專有系統不同，為建築業主提供了供應商獨立性和長期產品可用性】

Interface cables and Actuator Sensor Interface (AS-Interface / AS-i) cables provide standardized connections for automated solution network protocols. AS-Interface, standardized under IEC 62026-2, is a simple, cost-effective fieldbus for connecting binary sensors and actuators at the lowest level of the automation pyramid. The protocol uses a distinctive yellow flat cable design that allows devices to be connected anywhere along the cable using insulation-piercing connectors, without the need for T-connectors or termination resistors. This unique “pierce anywhere” technology dramatically simplifies installation and allows easy addition or repositioning of devices. General interface BUS cables provide flexible solutions for various industrial communication standards where specific protocol cables are not required.
