主要由系统内部元器件及电路间的相互电磁辐射产生，如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PLC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，可不多考虑，但要选择具有较多应用实绩或经过考验的系统。


三、PLC控制系统工程应用的抗干扰设计


为了保证系统在工业电磁环境中免受或减少内外电磁干扰，从设计阶段开始便采取三个方面措施：干扰源；切断或衰减电磁干扰的传播途径；提高装置和系统的抗干扰能力。这三点就是电磁干扰的基本原则。


PLC控制系统的抗干扰是一个系统工程，要求制造单位设计生产出具有较强抗干扰能力的产品，且有赖于使用部门在工程设计、安装施工和运行维护中予以考虑，并结合具有情况进行综合设计，才能保证系统的电磁兼容性和运行可靠性。进行具体工程的抗干扰设计时，应主要以下两个方面。
