Overview

效率
Greater global competition means that companies must use
their resources economically and efficiently. This applies in par-
ticular to production. This is where PROFINET ensures greater
效率。简单的工程保证快速调试，
虽然可靠的设备可确保高水平的工厂可用性。
Comprehensive diagnostic and maintenance concepts help to
reduce plant downtimes and keep maintenance costs to a
minimum.
One cable for everything

isochronous mode and standard IT communication (TCP/IP) on

the user/process data and diagnostic data takes place on a
单电缆。特定的个人资料通信（Profisafe，
PROFIdrive and PROFIenergy) can be integrated without any
additional cabling. This solution offers a wide scope of functions
at a low level of complexity.
Device and network diagnostics
通过保留尝试和测试的Profibus设备模型，
same diagnostics information is available with PROFINET. In
此外，也可以读取模块和频道特定数据
设备诊断期间从设备出来，使故障达到
be located quickly and easily. Apart from the availability of de-
vice information, the reliability of the network operation has top
网络管理中的优先级。
In existing networks the Simple Network Management Protocol
(SNMP) has established itself as the de facto standard for the
维护和监视网络组件和
their functions. PROFINET uses this standard and gives users
the opportunity to maintain their networks with tools that are
他们熟悉的，例如Sinema服务器网络管理 -
ment software.
For easier maintenance of PROFINET devices, both on-site and
remotely via a secure VPN connection, application-specific web-
sites can be set up on the integrated Web server of the field
devices using the familiar HTML standard.
Energy efficiency
En route to the green factory: PROFIenergy is a profile that
provides functions and mechanisms for PROFINET field devices
that support energy-efficient production.

any manufacturers or devices, enables the energy demand and

对于机器构建器而言，profienergy的使用变得容易
by its integration into familiar series of products. In addition,

简单的接线
Particularly stringent demands are made on the installation of
在工业环境中有线。此外，还有一个
quirement to set up industry-standard networks in the shortest
possible time without any special knowledge.
With FastConnect, Siemens is offering a high-speed installation
system that meets all of these requirements. FastConnect is the
standard-compliant, industrial cabling system consisting of
cables, connectors and assembly tools for PROFINET networks.
The time required for connecting terminals is minimized by the
simple installation method using just a single tool, while installa-
tion errors are prevented by the practical color-coding. Both
铜电缆和玻璃光纤电缆很容易组装 -
bled on site.
快速设备更换
profinetdevices are identified by means of a name assigned
during configuration. On replacing a defective device, a new de-
vice can be recognized from its topology information by the IO
controller and a new name can be assigned to it automatically.
这个means that no engineering tool is necessary for the replace-
ment of equipment.
这个mechanism can even be used for the initial commissioning
of a complete system. This speeds up commissioning, particu-
larly in the case of series machines.
坚固
An automation network must be robustly protected against
external sources of interference. The use of Switched Ethernet
防止网络中一部分的故障影响整个
plant network. For areas that are particularly prone to radio
frequency interference (RFI), PROFINET allows the use of fiber
optic cables.
