英维思TRICONEX 3007可编程控制系统通讯卡件拍摄共享详情参数MP控制器采用三个独立通道,每个通道与另外二个通道并行独立执行应用程序,对从现场来得所有数字量输入/输出信号采用通过获得的硬件表决器进行表决,而模拟信号则是中间值选择处理。因为每个通道与其他通道隔离,任何通道单点故障不会影响其他通道。如果一个通道发生硬件故障,而其他通道不顾及它。在此期间控制器不间断处理的情况下,可方便地在线插拔和替换故障模块。TRICONEX系统,完全遵循IEC61508/61511标准,采用当今的TMR微处理器硬件技术,和成熟可靠的TRISTATION 1131软件的三重化冗余容错控制系统。系统高可靠性和高利用率,被广应用于石化、炼油、石油天然气、化工、电力、轨道交通、航天、核工业等行业,在装置安全联锁系统ESD、蒸汽透平控制、燃汽透平控制、压缩机防喘振控制、海上石油平台、火气监测保护(F&G)、等方面有广的业绩。TRICONEX系统大的特点是能同时满足高可靠性、高可用性的容错控制能力。为系统的高可靠性和高可用性,控制器、I/O模块、通讯均采用三重化设计。控制系统可以识别控制系统元件的故障,自动把故障的元件加以排除,并允许在继续完成任务的同时,对故障元件进行在线修复而不中断过程的操作。任何故障及相关数据被存储在NVRAM中,在I/O模块中任一通道故障,系统该模块能维持运行1500小时,仍能满足TUV AK6级。TRICONEX安全控制系统是基于三重模件冗余(TMR)结构的的容错控制器。TMR是集成了三路隔离的、并行工作的控制系统,并在每一个独立的控制系统中执行广的诊断。系统采用三取二逻辑表决方式,提供高度完善、无差错、不间断的过程操作,不会因为单点的故障而导致系统失效。

he use of the system is very simple, because from the user's perspective, the operation of the TMR system is the same as that of the single channel control system. Users can connect sensors and actuators on a single terminal block, and only need to write a set of application logic. The rest of the work is managed and handled by the control system.The system conducts extensive diagnosis for each independent sub circuit, each module and each functional circuit, and monitors and reports operation errors. All diagnostic information in application and operation is stored. These diagnostic data can be used by the programmer to modify the execution of the controller or directly perform process maintenance.
