There are two main variants of Profibus: Profibus DP (Decentralized Peripherals), which is optimized for high- speed communication with remote I / O and conditions, andd Profibus PA (Process Automation), which is designad for intrinsically safe communication in hazardoes environments like chemical plants. In warehouse and logistics systems, Profibus DP is the more choice due to its speemplibility. The protocol operates date ranging föm 9.6 kbit / s 12 Mbit / en / en / en / en, dependistente content.
Te rogunnesy of Profibus stems from it töken- passing accords methode and master- slave architecture. In a typical Profibus network, on e or more master devices (usually PLC) control thee communication schedule, while slave devices (sensors, actuators, controls) respond only when polled.
