此外IEC61131-3将标准编程技术和当代编程语言的优点结合起来。IEC61131-3定义了不同的数据类型和标准功能和/或功能模块，能够容易和更快地写出自己的应用。通过使用标准的功能和/或功能模块，缩短了编程时间，使用自由定义的变量(不限标志的数量)，结构编程以及面向目标的功能和功能块。
PLC硬件
遵从IEC61131-3的PLC固件都可与SYS公司和PHY公司不同的标准模块相接。因此有集中式和分散型扩展IOs的PLC硬件。为了使用具有分散型IO模块的PLC，就需要通过CANopen现场总线组网。基本的方法是采用不同产品的CANopen IO模块。我们在开发硬件方面的经验加上众多的设计模型能够快速地建立客户专用硬件。为了控制进程，我们提供与CANopen或RS232接口的人机界面(MMI)。
