描述

SBI-PDP-32 现场总线

Profibus-DP是一种现场总线，用于与传感器/执行器相关的快速数据交换;在主中心单元(PLC或PC)和从单元(即传感器、执行器、驱动器等)之间建立通信。

数据交换是循环的;主单元读取从机的输入数据并写入从机的输出数据。母线周期时间比中央机组周期时间短;根据Profibus-DP标准部分，Profibus-DP接口卡的波特率范围为9.6 kbit/s ~ 12mbit /s。3.

将支持财政è quello标准Profibus-DP;所有的公共汽车都拥有大量的附属品，数量最多的是125个奴隶。

总周期时间取决于连接的slave的数量;1.5 mbit /s波特率允许在6毫秒内轮询8个驱动器。物理支持标准的Profibus-DP;马克斯。连接到总线的slave的数量是125。

Profibus-DP is a field Bus designed for a fast data exchange relating to sensors/ actuators; the communication is established between a Master central unit(PLC or PC) and Slave units, i.e. sensors, actuators, drives, etc.

The data exchange is cyclic; the Master unit reads the Slaves input data andwrites the Slaves output data. The Bus cycle time is shorter than the cycle timeof the central unit; the Baud Rates for the Profibus-DP interface card are from9,6 kbit/s to 12 Mbit/s according to Profibus-DP standard part. 3.

Il supporto fisico è quello standard Profibus-DP; al Bus possono essere collegati un numero massimo di 125 Slave.

The total cycle time depends on the number of Slaves connected; the 1.5-Mbit/s Baud Rate allows 8 drives to be polled in 6 milliseconds. The physical support is standard Profibus-DP; the max. number of Slavesconnected to the Bus is 125.
