PLC控制器在过程控制中的应用已经非常普及,随着技术的进步,PLC控制器由初期的逻辑控制、顺序控制已发展到如今能与DCS相抗衡的过程巨量模拟量的处理控制,而PLC控制器在实现流程式过程控制中具有的程序直观性、可读性、易调性、易掌握性等是控制工程师非常喜爱的,但其编程的灵活性又值得控制工程师永无止境地探究。
The application of PLC controller in process control has been very popular. With the advancement of technology, the PLC controller is controlled by the initial logic, and the sequence control has been developed to control the huge amount of analog quantity of the process which can contend with DCS at present. PLC controller in the process of process control to achieve the program has intuitive, readable, easy to adjust, easy to grasp, etc. is a favorite of control engineers, but its programming flexibility is worth controlling engineers endless exploration .
