2841 控制器TRICONEX系统大的特点是能回时满足高可靠性、可用性的容错控制能力。为保证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,并允许在继续完成指定任务的同时,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-通道故障,系统保证该模块能维持运行1500小时,仍能满足TUVAK6级。
The major feature of the TRICONEX system is its ability to meet high reliability and availability fault-tolerant control requirements in real-time. To ensure the high reliability and availability of the system, the controller, I/O module, and communication all adopt a triple design. The control system can identify faults in control system components, automatically eliminate faulty components, and allow online repair of faulty components without interrupting the process while continuing to complete specified tasks. Any faults and related data are stored in NVRAM, and in case of any channel fault in the I/O module, the system guarantees that the module can maintain operation for 1500 hours and still meet TUVAK6 level.
