VB程序结合RS触发器实现第一事故报警确认

Realizing the Alarm Affirmative of the First Accident by VB Program Combined with RS Trigger

在连续长周期的化工生产过程中,一旦出现停车故障,第一报警的确认就成为判断停车原因的关键。通过VB程序结合RS触发器应用在DCS系统中,可以实现第一事故报警确认。

In the chemical engineering production process of the continuous long cycle, once the stalling fault appears, the alarm affirmative of the first accident is the hinge of judging stalling causes. Through VB program combined RS initiator in DCS system, the alarm affirmative of the first accident can be realized.
