The logic voltage interference tolerance of DCS work is low,and the distribution interference of the logic ground potential easily affects the logic operation and data storage of the DCS,resulting in data confusion,program runaway or crash.The distribution of the analog ground potential will lead to a decrease in the measurement accuracy,causing serious distortion and malfunction of the signal measurement and control.
DCS工作的逻辑电压干扰容限较低,逻辑地电位的分布干扰容易影响DCS的逻辑运算和数据存贮,造成数据混乱、程序跑飞或死机。模拟地电位的分布将导致测量精度下降,引起对信号测控的严重失真和误动作。
