ActiveDigital data communication for measurement and control - Fieldbus for use in industrial systems Type 3: PROFIBUS specification - Part 2: Physical layer specification and service definition
测量和控制数字数据通信 工业控制系统用现场总线 类型3：PROFIBUS规范 第2部分：物理层规范和服务定义
Application Summary AI generated
This standard specifies the physical layer requirements for PROFIBUS fieldbus communication in industrial control systems, defining electrical and mechanical parameters for data transmission over twisted-pair cables or fiber optics. It is applied in manufacturing automation, process control, and factory-floor networks to ensure reliable, deterministic communication between sensors, actuators, and programmable logic controllers (PLCs). The standard is used by engineers for designing, installing, and testing PROFIBUS networks in industries such as automotive, chemical, and discrete manufacturing.
