SMC总线阀岛模块EX120-SPR1-B电磁阀结构

现场总线系统是一个全分散、全数字化、全开放和可互操作的过程自动控制系统。SMC的创新成果，现场总线技术为您提供分散的沟通，需要为你的控制设计的灵活性。

SMC支持多种开放式现场总线协议，以满足您的网络需求，包括EtherNetIP，PROFINET，EtherCAT，DeviceNet,Profibus DP等总线协议。

现场总线(Field bus)的实质是通过电信号传输方式，并以一定的数据格式实现控制系统中信号的双向传输。两个采用现场总线进行信息交换的对象之间只需一根两股或四股的电统连接。

特点是以一对电缆之间的电位差方式传输的。在由带现场总线的阀岛组成的系统中，每个阀岛都带有一个总线输入口和总线输出口。这样当系统中有多个带现场总线阀岛或其它带现场总线设备时可以由近至远串联连接。

现提供的现场总线阀岛装备了目前市场上所有开放式数据格式约定及主要可编程控制器自定的数据格式约定。这样，带现场总线阀岛就能与各种型号的可编程控制器直接相连接，或者通过总线转换器进行阀接连接。

Fieldbus system is a fully decentralized, fully digital, fully open and interoperable process automatic control system. The innovative result of SMC's fieldbus technology gives you the decentralized communication needed for your control design flexibility.

SMC supports several open fieldbus protocols to meet your network needs, including EtherNetIP, PROFINET, EtherCAT, DeviceNet,Profibus DP and other bus protocols.

The essence of the Field bus (Field bus) is through the transmission of electrical signals, and in a certain data format to achieve the two-way transmission of signals in the control system. Two objects that use fieldbus for information exchange only need a two-strand or four-strand electrical connection.

The feature is transmitted by the potential difference between a pair of cables. In a system consisting of a valve island with a fieldbus, each valve island has a bus input and a bus output. In this way, when there are multiple valve islands with fieldbus or other devices with fieldbus in the system, it can be connected in series from near to far.

The available fieldbus valve islands are equipped with all open data format conventions currently available on the market and data format conventions customized by major programmable controllers. In this way, the valve island with fieldbus can be directly connected to various types of programmable controllers, or through the bus converter valve connection.
