现代的PLC的编程语言遵从易学、易懂、易用的标准。除了具备传统PLC助记符和梯形图编程功能外，还具有结构化语言和顺序功能图编程功能。PLC提供各种功能模块，包括各种通讯功能选择、通讯参数设置，以及可以具体到某年、某月、某日、某个时刻的多种定时器和超长定时器等，方便了各种功能的实现，有利于缩短开发周期和节省程序容量。
4 控制方法
4.1
对于冷冻水系统，其出水温度取决于蒸发器的设定值，而回水温度取决于蒸发器接收的热量，中央空调冷冻水出水温度与冷冻水的回水温度设计最大温差为：5℃（比如：出水7℃，回水12℃），现采用在蒸发器出水管和回水管上装有检测其温度的变送器、PID温差调节器和变频器组成闭环控制系统，通过冷冻水温差（如：△T=5℃）控制，即可使冷冻水泵的转速相应于热负载的变化而变化。
4.2
对于冷冻水系统，由于低温冷冻水的温度取决于冷却塔的工作情况，我们只需控制高温冷冻水（ 冷凝器出水）的温度，即可控制温差。现采用温差变送器、 PID 调节器和变频器组成闭环控制系统，冷凝器出水的温度控制在 T2 （ 如： 37℃），使冷却水泵的转速相应于热负载的变化而变化。
