多种认证

PLC系统应能提供离散控制、驱动器控制、运动控制、流程控制和*控制等多种类型的控制，而且具有**、多类型的开放通信网络，连接各种远程、分布式、高性价比的I/O。系统应为模块化结构，这使用户*设计、建立和修改系统，有效节省培训和工程费用。

 

1.离散控制系统

 

离散控制是PLC擅长的控制领域，广泛应用于产品加工行业和产品装配行业。

 

简单的PLC系统在机架中只包含单一控制器和多个I/O模块。而复杂系统会有下列情况：

 

一个机架中有多个控制器；

 

多个控制器接入多个网络；

 

I/O位于多个平台，分布在多个位置，可通过多个I/O总线或网络链接。

 

2.冗余控制系统

 

为了提高PLC系统的**性和可用性，工厂工艺通常需要PLC系统能够支持冗余控制。确保即使在工作控制器失效时，能够切换到备份控制器继续工作。

 

下图为施耐电气2016年推出的全新一代用于冗余控制的以太网可编程自动化控制器（ePAC）昆腾+ePAC。

 

流程控制系统

 

流程工业是工业的一大分支，如石油、、精炼等行业，过去是分布式控制系统（DCS）的，随着PLC的性能提高和对IEC61131–3的功能块语言的支持，很多PLC已经能够胜任流程工艺的控制。
