多种认证
PLC系统应能提供离散控制、驱动器控制、运动控制、流程控制和安全控制等多种类型的控制,而且具有高性能、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,这使用户容易设计、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系统的可靠性和可用性,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、化工、精炼等行业,过去是分布式控制系统(DCS)的天下,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。
