PLC控制器在安装、调试方面的特点
The features of PLC controller in installation and debugging
PLC用软件功能取代了继电器控制系统中大量的中间继电器、时间继电器、计数器等器件,使控制柜的设计、安装、接线工作量大大减少。
PLC uses software function to replace a large number of relay, time relay, counter and other devices in the relay control system, so that the design, installation and wiring work of the control cabinet is greatly reduced.
PLC的梯形图程序一般采用顺序控制设计法来设计。这种编程方法很有规律,很容易掌握。对于复杂的控制系统,设计梯形图的时间比设计相同功能的继电器系统电路图的时间要少得多。
The ladder diagram program of PLC is usually designed by sequential control design. This programming method is very regular and easy to master. For complex control systems, the design time of ladder diagram is much less than that of relay circuit diagram with the same function.
PLC的用户程序可以在实验室模拟调试,输入信号用小开关来模拟,通过PLC上的发光二极管可观察输出信号的状态。完成了系统的安装和接线后,在现场的统调过程中发现的问题一般通过修改程序就可以解决,系统的调试时间比继电器系统少得多。
The user program of PLC can be simulated in the laboratory, the input signal is simulated with a small switch, and the output signal can be observed by the light emitting diode on the PLC. After the installation and wiring of the system is completed, the problems found in the field adjustment process can be solved by modifying the program, and the debugging time of the system is much less than that of the relay system.
