美国电气制造商协会(NEMA)给他起了一个新名字“可编程控制器”，简称PC。

1982年，国际电工委员会(IEC)专门为可编程控制器定义了严格的定义。然而，在中国，PC的缩写一直是个人电脑的代名词。

为了避免术语的混淆，在中国仍采用早期的缩写名称PLC来表示可编程控制器，但这种PLC并不意味着它只具有逻辑功能。

可编程控制器的定义可编程控制器一直在发展，所以直到现在，它还没有能够确定最终的定义。

The National Electrical Manufacturers Association (NEMA) gave him a new name "Programmable Controller", or PC for short.

In 1982, the International Electrotechnical Commission (IEC) specifically defined a strict definition for programmable controllers. However, in China, the abbreviation PC has always been synonymous with personal computer.

In order to avoid confusion of terminology, the early abbreviated name PLC is still used in China to indicate programmable controller, but this PLC does not mean that it only has logical functions.

The definition of a programmable controller is evolving all the time, so until now, it has not been able to settle on a final definition.
