与个人计算机相比，PLC在标准化方面作得较差：PLC的软、硬件体系结构是封闭的而不是开放的；绝大多数PLC使用专用的总线、专用通信网络及协议；各种PLC产品的编程语言在表示方式、寻址方式和语法结构上都不一致，使得它们互不兼容。国际电工委员会的IEC6113l-3《可编程序控制器的编程软件标准》为PLC编程的标准化铺平了道路。不少厂家正在开发以PC(个人计算机)为硬件平台、在WINOOWs操作系统下、符合IEC61131-3国际标准的新一放体系结构的PLC。
为了增强PLC的抗干扰能力，提高其可靠性，PLC的每个开关量输入端都采用光电隔离等技术。
此外，在I/O模块的安装时，根据不同的系统，通常同型号的模块放置在一起。但是，。如果对于输出模块与输入模块形成回路的，则可以将一个回路的参量所涉及的模块放置在一个机架上（或一个CPU所控制的机架上）比较合理。有的在设计的时候不会考虑这一点，你可以调整过来。
注意：务必将与光纤单元相连的一侧先嵌入导轨进行安装，逆向安装会导致安装强度下降。
PAC的轻便控制引擎是非常杰出的。PAC设计了一个通用的、软件形式的控制引擎用于应用程序的执行，控制引擎在实时操作系统与应用程序之间，这个控制引擎与硬件平台无关，可以在不同平台的PAC系统间移植。因此对于用户来说，同样的应用程序不需根据系统的功能需求和投资预算选择不同性能的PAC平台。这样，根据用户需要的迅速扩展和变化，用户的系统和程序无需变化，即可无缝移植。PAC的操作系统采用通用的实时操作系统
从市场上看，各国各自生产多品种产品的情况会随着国际竞争的加剧而打破，会出现少数几个品牌垄断国际市场的局面，会出现国际通用的编程语言；
