信号源接地时，屏蔽层应在信号侧接地；不接地时，应在PLC侧接地；信号线中间有接头时，屏蔽层应牢固连接并进行绝缘处理，一定要避免多点接地；多个测点信号的屏蔽双绞线与多芯对绞总屏电缆连接时，各屏蔽层应相互连接好，并经绝缘处理。选择适当的接地处单点接点。

可编程控制器（Programmable Logic Controller）简称PLC或PC，是从早期的继电器逻辑控制系统发展而来，它不断吸收微计算机技术使之功能不断增强，逐渐适合复杂的控制任务。

PLC之所以有生命力，在于它加适合工业现场和市场的要求：高可靠、强抗各种干扰的能力、编程安装使用简便、低价格长寿命。比之单片机，它的输入输出端接近现场设备，不需添加太多的中间部件或需要多的接口，这样节省了用户时间和成本。PLC的下端(输入端)为继电器、晶体管和晶闸管等控制部件，而上端一般是面向用户的微型计算机。人们在应用它时，可以不必进行计算机方面的专门培训，就能对可编程控制器进行操作及编程。用来完成各种各样的复杂程度不同的工业控制任务。
