plc要求环境温度在0~55℃，安装时不能放在发热量大的元件下面，四周通风散热的空间应足够大，基本单元和扩展单元之间要有30mm以上间隔；开关柜上、下部应有通风的百叶窗，防止太阳光直接照射；如果周围环境超过55℃，要安装电风扇强迫通风。
离线编程示指主机和编程器共用一个cpu，通过编程器的方式选择开关来选择plc的编程、监控和运行工作状态。编程状态时，cpu只为编程器服务，而不对现场进行控制。专用编程器编程属于这种情况。在线编程是指主机和编程器各有一个cpu，主机的cpu完成对现场的控制，在每一个扫描周期末尾与编程器通信，编程器把修改的程序发给主机，在下一个扫描周期主机将按新的程序对现场进行控制。计算机辅助编程既能实现离线编程，也能实现在线编程。在线编程需购置计算机，并配置编程软件。采用哪种编程方法应根据需要决定
在系统正常运行时，plc的输入、输出信号和内部的信号（如存储器为的状态）相互之间存在着确定的关系，如出现异常的逻辑信号，则说明出了故障。因此可以编制一些常见故障的异常逻辑关系，一旦异常逻辑关系为on状态，就应按故障处理。如机械运动过程中先后有两个限位开关动作，这两个信号不会同时接通。若它们同时接通，说明至少有一个限位开关被卡死，应停机进行处理。在梯形图中，用这两个限位开关对应的存储器的位的常开触点串联，来驱动一个表示限位开关故障的存储器的位就可以进行检测。

机械手是一种能自动化定位控制并可重新汇编程序以变动的多功能机器。它有多个自由度。，可用来搬运物体以完成在各个不同环境中的工作。工业机械手是近似自动控制领域中出现的一项新技术，并已成为现代制造生产系统中的一个重要组成部分。
plc控制器为了与所控的各个设备同电位而接地，叫系统接地。接地电阻值不得大于4ω，一般需将plc设备系统地和控制柜内开关电源负端接在一起，作为控制系统地。
