FANUC A06B-6096-H203伺服放大器模块
PROFIBUS系列由三种类型的协议组成，每种协议用于不同的任务。当然，具有所有三种协议的设备可以通过PROFIBUS网络在复杂系统中相互通信。三种协议类型是：PROFIBUS FMS、DP和PA。只有DP和PA两种协议类型对过程自动化很重要。PROFIBUS DP：分散外围设备的总线PROFIBUS DP（RS 485）负责过程自动化系统的控制器级与现场分散外围设备之间的通信，以及通过DP Ex屏障进入危险区域的本质安全（RS485-is）。PROFIBUS DP的一个特点是传输速度高达12 Mbit/s。PROFIBUS PA：过程自动化的扩展此PROFIBUS变体是为过程工业开发的。变送器和定位器的通信和电源直接通过一根双线电缆进行处理，并符合IEC标准61158-2（也称为MBP、MBP-LP）。1区/分区的本质安全（EEx i）（MBP-IS）装置
The PROFIBUS family is composed of three types of protocol, each of which is
used for different tasks. Of course, devices with all three protocols can communicate
with each other in a complex system by means of a PROFIBUS network.
The three types of protocols are: PROFIBUS FMS, DP and PA.
Only the two protocol types DP and PA are important for process automation.
PROFIBUS DP: the bus for the decentralized periphery
The PROFIBUS DP (RS 485) is responsible for communication between the
Controller level of a process automation system and the decentralized periphery in
the field, also intrinsic safety (RS485-IS) via DP-Ex barriers into hazardous area.
One feature of PROFIBUS DP is its high speed of transmission up to 12 Mbit/s.
PROFIBUS PA: extension for process automation
This PROFIBUS variant was developed for the process industry. Communication
and power supply to Transmitter and Positioners are handled direct via one 2-line
cable and correspond to IEC Standard 61158-2 (named also as MBP, MBP-LP).
