编码器信号输出主要有并行格雷码输出、串行ssi输出、总线型输出、模拟量4~20ma输出。并行格雷码和模拟量输出信号读取简单但不适合长距离传输，串行ssi输出大部分是与西门子plc的ssi模块配套成本较高。现场总线型编码器用通讯方式传输信号，信号遵循rs485的物理格式，连接线少，传输距离远，对于编码器的保护和可靠性就提高了。信号的接收设备只需一个接口，就可以读多个编码器信号，多个编码器集中控制的情况下可以大大节省成本。

EPEROM为可电擦除只读存储器，须用紫外线照射芯片上的透镜窗口才能擦除已写入内容，可电擦除可编程只读存储器还有E2PROM、FLASH等。
变频器与EC20的PORT1通讯端口采用自由口协议通讯。运行中PLC向变频器发送启动、停止、频率设定三种命令，具体发送时刻和发送周期由程序中的逻辑控制。
执行器故障；
用户程序是随PLC的控制对象而定的，由用户根据对象生产工艺的控制要求而编制的应用程序。为了便于读出、检查和修改，用户程序一般存于CMOS静态RAM中，用锂电池作为后备电源，以保证掉电时不会丢失信息。为了防止干扰对RAM中程序的破坏，当用户程序经过运行正常，不需要改变，可将其固化在只读存储器EPROM中。现在有许多PLC直接采用EEPROM作为用户存储器。
传统上，工业机器人使用复杂的专用语言进行编写，除了机器人编程人员可以理解外，其它人根本弄不明白。运动控制器的范围要广一些，而且变化也比较多，一般使用PC库或其它专用语言进行编程，而PLC则一般使用梯形图逻辑进行编程。在当今的自动化环境中，PLC、运动控制器和机器人必须紧密的集成在一起。很多元素被集成到机器设计中，而每个元素的优势，都需要通过专用语言的编程体现出来。
PLC可以通过通迅接口与显示终端和打印机等外设相连。显示器作为人机界面（HMI）是一种内含微处理芯片的智能化设备，它与PLC相结合可取代电控柜上众多的控制按钮、选择开关、信号指示灯，及生产流程模拟屏和电控柜内大量的中间继电器和端子排。所有操作都可以在显示屏上的操作元件上进行。PLC可以方便、快捷地对生产过程中的数据进行采集、处理，并可对要显示的参数以二进制、十进制、十六进制、ASCII字符等方式进行显示。在显示画面上，通过图标的颜色变化反应现场设备的运行状态，如阀门的开与关，电机的启动与停止，位置开关的状态等。PID回路控制用数据、棒图等综合方法反映生产过程中量的变化，操作人员通过参数设定可进行参数调整，通过数据查询可查找任一时刻的数据记录，通过打印可保存相关的生产数据，为今后的生产管理和工艺参数的分析带来便利。

智能编程器又称图形编程器，本质上它是一台专用便携式计算机，如三菱的GP-80FX-E智能型编程器。它既可联机编程，又可脱机编程。可直接输入和编辑梯形图程序，使用更加直观、方便，但价格较高，操作也比较复杂。大多数智能编程器带有磁盘驱动器，提供录音机接口和打印机接口。

PLC是一种控制机器动作顺序的“程控型”控制器，它在固化的系统程序的支持下，按照“输入采样→用户程序运算→输出刷新”的步骤循环地工作，反复地执行用户程序来实现预定的控制功能，并且支持用“(虚拟)继电器语言”(如“梯形图”)来编写用户程序。
