现场总线带DP光纤走进通信网络

date:On November 17, 2017 Source:  

   DP光纤的协议一直出现在现场总线的文章里,什么是现场总线?近年来迅速发展起来的一种工业数据总线,它主要解决工业现场的智能化仪器仪表、控制器、执行机构等现场设备间的数字通信以及这些现场控制设备和高级控制系统之间的信息传递问题。由于现场总线简单、可靠、经济实用等一系列突出的优点,因而受到了许多标准团体和计算机厂商的高度重视。然而对于现场总线的意义就是以数字通信替代传统的模拟信号。那么DP光纤又是怎么在现场总线工作的,下面来自于利诺威DVI光纤厂家对于DP光纤简述。

DP fiber protocol has been in the fieldbus article, what is the fieldbus? In recent years, a rapidly developing industrial data bus, which is mainly to solve industrial field intelligent instrumentation, controllers, actuators and other field devices, digital communications and field control devices and advanced control systems between the issue of information transfer . Due to the fieldbus is simple, reliable, economical and practical and a series of outstanding advantages, which has been many standard groups and computer manufacturers attach great importance. However, the significance of fieldbus is to replace traditional analog signals with digital communications. Then DP fiber is how to work in the field bus, the following from the Linuo Wei DVI fiber optic fiber manufacturers for DP brief.

   DP光纤又是网络的一部分,在现在总线的一个环节里饰演一个光纤中继器,其实这是对于PROFIBUSDP总线支持的意思,独立双总线电接口及2个光纤接口,提供冗余双总线结构及光纤冗余环网功能,为冗余双网系统提供安全高效的光纤冗余长距离传输及中继功能,这就是DP光纤的由来,其实在很多大型的音乐会现场上,或者是表演节目都是用到了该方案的,只是没有去注重这一环节罢了。

DP optical fiber is a part of the network, in a link nowadays play a fiber optic repeater, in fact, this is the meaning of the PROFIBUSDP bus support, an independent dual bus electrical interface and two optical interfaces to provide redundant dual-bus structure and Fiber redundant ring network function, for redundant dual-network system to provide safe and efficient long-distance optical fiber redundancy and relay function, which is the origin of DP fiber, in fact, in many large concert scene, or show all Is the use of the program, but did not pay attention to this link.


   还有一些起其它的DP光纤产品,都是用于现场总线的协议的,总之而言DP光纤就是用于现场的的设备,了解更多的传输方案协议就在利诺威。

There are also other DP fiber optic products that are used for fieldbus protocols. In short, DP fiber is the equipment used in the field. Learn more about the transmission protocol at Lehman.
