Overview

大量结构
The use of PROFINET makes it possible to overcome the existing
关于机器和系统范围的限制
can be implemented. In one network, several different control-
lers can interact with their assigned field devices. The number of
每个PROFINET网络的现场设备几乎是无限的 -
entire range of IP addresses is available.
高数据率
By using 100 Mbit/s in full duplex mode, PROFINET achieves a
比以前的现场总线显着更高的数据速率。这
意味着可以通过TCP / IP传输其他工厂数据 -
out any problems, in addition to the process data. PROFINET
therefore meets the combined industrial demands for simultane-
ously transmitting high-speed IO data and large volumes of data
for additional sections of the application. Even the transmission

Media redundancy
冗余可以实现更高的植物可用性
安装（环形拓扑）。媒体冗余可以是IM-
不仅借助外部交换机，而且还通过
集成PROFINET接口的手段。使用媒体
冗余协议（MRP），重新配置200毫秒
can be achieved. If the communication is interrupted in just one
part of the ring installation this means that a plant standstill is
prevented and any necessary maintenance or repair work can
在没有任何时间压力的情况下进行。
For motion control applications, PROFINET IRT in ring topolo-
GIES为计划Duplica提供扩展的媒体冗余 -
（MRPD）在没有任何内容的丧失压力模式下运行
reconfiguration time. If communication is interrupted (e.g. a
cable break) the process can continue operating without inter-
ruption.
系统冗余
SINAMICS S120 supports the PROFINET function "system
冗余“：SINAMICS S120现在可以连接到高 -
availability systems such as SIMATIC S7-400H with two control-
lers. No additional hardware is required to make the connection.
Complex automation tasks in the process industry, in particular,
where plant availability and redundancy of the control system
是必不可少的，需要可靠的沟通与高可原则
能力系统。两个控制器的高可用性系统
始终可以访问SINAMICS S120。在一个事件中
cable break or failure of a CPU, the other controller takes over,
thus ensuring uninterrupted communication.
