The mutual radiation of logic circuits and their influence on analog circuits,the mutual influence of analog ground and logic ground,and the mismatching use of components.This is the content of the electromagnetic compatibility design of the system by the DCS manufacturer,which is relatively complicated and cannot be changed as an application department.

逻辑电路相互辐射及其对模拟电路的影响，模拟地与逻辑地的相互影响及元器件间的相互不匹配使用等。这都属于DCS制造厂对系统内部进行电磁兼容设计的内容，比较复杂，作为应用部门是无法改变的，可不必过多考虑，但要选择具有较多应用实绩或经过考验的系统。
