产生的错误;诊断系统,监视系统状态;强制FSC参数以切断控制回路,以便进行程序测试或现场设备的维护。 FSC SOE完成系统的事件顺序记录功能,I/O卡件通过HBUS和VBUS给中央控制单元提供事件顺序能力,在每次扫描期间,控制单元检查所有变量的状态改变。当一个事件发生时,控制器将变量的当前状态和时间协签存储在缓冲区内,以便组态提取事件顺序。SOE的识别时间间隔为≤1ms,SOE的事件记录存储高达20万条,可实时存贮在硬盘中,并可通过打印机打印出来。 2逻辑控制功能 2.1 逻辑功能 故障安全控制系统的应用程序通过功能逻辑图来实现,功能逻辑图简称FLD,系统提供大量的逻辑、算术、计时、计数、PID等运算模块,用户可根据设计需要,选择相应的I/O符号,直接使用与、或、非的逻辑图的方式实现用户的逻辑功能,此外,用户还可以用系统自带的Function Block模块定义需要的功能块,以子程序的形式在其他程序中调用,实现较为复杂的逻辑控制。I催FSC系统中定义了RS触发器、温压补偿、延时计数器、二取二、三取二等逻辑功能块,多次在其他的子逻辑中得到调用。 以RS触发器和三取二子程序为例的逻辑功能块FB900、FB930结构如图3及图4所示:one of Honeywell's larger automation contract wins in China. Other recent wins include a $4M contract with CNOOC Limited, China's largest offshore oil producer, and a $3.2M contract with China Petroleum and Chemical Corporation (SINOPEC) for automation of a refined oil products pipeline in southwest China.
