AS-I网——传感器和执行器通信的国际标准，扫描时间5ms，传输媒体为未屏蔽的双绞线，线路长度为300m，多为31个从站。

PROFIBUS——工业现场总线，用于车间级和现场级的国际标准，传输率大12m/s，传输媒体为屏蔽双线电缆(长9.6km)或光缆长90km)，多可接127个从站。

工业以太网——用于区域和单元联网的国际标准，网络规模可达1024站1.5km(电气网络)或200km(光学网络)。

在这一网络体系中，尤其值得一提的是PROFIBUS现场总线，PROFIBUS是目前成功的现场总线之一，已得到广泛地应用。它是不依赖生产厂家的、开放式的现场总线，各种各样的自动化设备均可通过同样的接口交换信息。

为数众多的生产厂家提供了优 质的PROFIBUS产品，用户可以自由地选择合适的产品。PROFIBUS已经成为德国国家标准DIN19245和欧洲标准pr EN50170，并在世界拥有了多的用户数量。

AS-I network - international standard for sensor and actuator communication, scan time 5ms, transmission media is unshielded twisted pair, line length of 300m, up to 31 slave stations.

PROFIBUS - Industrial field bus, the international standard for workshop and field level, the transmission rate is up to 12m/s, the transmission media is shielded two-wire cable (up to 9.6km) or optical cable (up to 90km), and can connect to 127 slave stations.

Industrial Ethernet - an international standard for area and cell networking with a network scale of up to 1,024 stations 1.5km(electrical) or 200km(optical).

In this network system, especially worth mentioning is PROFIBUS fieldbus, PROFIBUS is one of the successful fieldbuses at present, has been widely used. It is not dependent on the manufacturer, open fieldbus, a variety of automation equipment can exchange information through the same interface.

A large number of manufacturers provide high-quality PROFIBUS products, users are free to choose the most suitable products. PROFIBUS has become the German national standard DIN19245 and the European standard PREN 50170, and has the largest number of users in the world.
