编程功能
离线编程方式：PLC和编程器公用一个，编程器在编程模式时，只为编程器提供服务，不对现场设备进行控制。完成编程后，编程器切换到运行模式，对现场设备进行控制，不能进行编程。离线编程方式可降低系统成本，但使用和调试不方便。在线编程方式：和编程器有各自的，主机负责现场控制，并在一个扫描周期内与编程器进行数据交换，编程器把在线编制的程序或数据发送到主机，下一扫描周期，主机就根据新收到的程序运行。这种方式成本较高，但系统调试和操作方便，在大中型PLC中常采用。
五种标准化编程语言：顺序功能图（SFC）、梯形图（LD）、功能模块图（FBD）三种图形化语言和语句表（IL）、结构文本（ST）两种文本语言。选用的编程语言应遵守其标准（IEC6113123），同时，还应支持多种语言编程形式，如C，Basic等，以满足特殊控制场合的控制要求。
(五)诊断功能
PLC的诊断功能包括硬件和软件的诊断。硬件诊断通过硬件的逻辑判断确定硬件的故障位置，软件诊断分内诊断和外诊断。通过软件对PLC内部的能和功能进行诊断是内诊断，通过软件对PLC的与外部输入输出等部件信息交换功能进行诊断是外诊断。
PLC的诊断功能的强弱，直接影响对操作和维护人员技术能力的要求，并影响平均维修时间。
(六)处理速度
PLC采用扫描方式工作。从实时要求来看，处理速度应越快越好，如果信号持续时间小于扫描时间，则PLC将扫描不到该信号，造成信号数据的丢失。
处理速度与用户程序的长度、处理速度、软件质量等有关。目前，PLC接点的响应快、速度高，每条二进制指令执行时间约0.2～0.4Ls，因此能适应控制要求高、相应要求快的应用需要。扫描周期（处理器扫描周期）应满足：小型PLC的扫描时间不大于0.5ms/K；大中型PLC的扫描时间不大于0.2ms/K。
四、机型的选择
PLC按结构分为整体型和模块型两类，按应用环境分为现场安装和控制室安装两类；按字长分为1位、4位、8位、16位、32位、64位等。从应用角度出发，通常可按控制功能或输入输出点数选型。
整体型PLC的I/O点数固定，因此用户选择的余地较小，用于小型控制系统；模块型PLC提供多种I/O卡件或插卡，因此用户可较合理地选择和配置控制系统的I/O点数，功能扩展方便灵活，一般用于大中型控制系统。
(二)输入输出模块的选择
输入输出模块的选择应考虑与应用要求的统一。例如对输入模块，应考虑信号电平、信号传输距离、信号隔离、信号供电方式等应用要求。对输出模块，应考虑选用的输出模块类型，通常继电器输出模块具有价格低、使用电压范围广、寿命短、响应时间较长等特点；可控硅输出模块适用于开关频繁，电感低功率因数负荷场合，但价格较贵，过载能力较差。输出模块还有直流输出、交流输出和模拟量输出等，与应用要求应一致。
可根据应用要求，合理选用智能型输入输出模块，以便提高控制水平和降低应用成本。
考虑是否需要扩展机架或远程I/O机架等。
