摘要
运用SIS系统自身的软件,对现有的联锁逻辑增设中间变量,并通过两种编程方式,实现联锁报警首出功能和联锁发生时间的记录。通过SIS系统HMI(人机界面接口)组态软件的画面组态,在画面上以列表的形式反应联锁报警发生的具体部位,便于及时判断和分析故障。
By using the software of the SIS system, adding the intermediate variables to the existing interlocking logic, through the two programming methods, realize the function which record the first inter- locking event and record the time when the first interlocking event occur. Through the picture configura- tion of the SIS system HMI ( man - machine interface) configuration software, on the picture in the form of a list, displaying the exact position where the first interlocking event occur, It is easy to timely judge and analyse of failure.
