分子筛顺序控制实施方案

Executive Schema for Sequential Control to Molecular Sieve

按照分子筛顺序控制的工艺操作要求 ,利用TIMER点参数的特点 ,确定了各个阀门开关及相应操作的时序。同时 ,考虑到工艺的各种控制操作要求 ,将CL控制程序与流程图画面有机地结合 ,提供了一个良好的人机界面。

According to operation requirement from sequence control to molecular sieve, and the characteristic of point parameter of timer, sequential procedure for valve’s action and corresponding operation is determined. A better interface between operator and machine is provided combinating CL controller program with flowsheeting diagram.
