HONEYWELL CC-TCNT01  伺服控制器 为了提高PLC系统的可靠和可用，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，过去是分布式控制系统（DCS）的，随着PLC的能提高和对HONEYWELL CC-TCNT01  伺服控制器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。 流程控制系统的一个要求是能够连接现场仪表，如：温度、压力、差压、流量、液位等变送器，有时要连接如：HART、FF和Profibus PA等现场总线。所以控制系统通常使用模块直接连接变送器，或通过网关连接现场总线变送器。 4.功能安全系统 经过功能安全完整等级（SIL）认的PLC可以提供功能安全控制。按照工厂的应用要求，PLC控制器必须选用符合相应的安全完整等级如SIL 3或能等级如PLe。 现在很多安全控制器可以与标准控制器混用，这种系统的主要好处是一个项目中安全与标准一起共用一个PLC平台。安全控制器是整个控制系统的一部分，可以自动配置，不需要用户干预。

Redundant control system In order to improve the reliability and availability of PLC system, factory technology usually needs PLC system to support redundant control. Ensure that even if the working controller fails, it can switch to the backup controller to continue working. The following picture shows the whole new generation of programmable automation controller (ePAC) quantum +ePAC for redundancy control introduced by Schneider Electric in 2016. Process control system Process industry is a big branch of industry, such as petroleum, refining, etc. It used to be distributed control system (DCS). With the improvement of PLC and the support of IEC 61131–3 function block language, many PLCs have been able to control the process technology. One requirement of process control system is to be able to connect with field instruments, such as transmitters for temperature, pressure, differential pressure, flow and liquid level, and sometimes to connect with field buses such as HART, FF and Profibus PA. Therefore, the control system usually uses the module to connect the transmitter directly, or connects the fieldbus transmitter through the gateway. 4. Functional safety system PLC recognized by functional safety integrity level (SIL) can provide functional safety control. According to the application requirements of the factory, the PLC controller must be selected to meet the corresponding safety integrity level such as SIL 3 or energy level such as PLe. Now many safety controllers can be mixed with standard controllers. The main advantage of this system is that safety and standards share a PLC platform in a project. The safety controller is a part of the whole control system, which can be automatically configured without user intervention.
