介绍了一种大型超细粉磨机电气控制部分的PLC顺序控制方案。通过对设备控制要求进行分析,确定了PLC输入输出信号的数量,选用适当的PLC装置并合理分配I/O点,设计了电控部分的总体方案。根据设备的运行过程,确定软件设计流程,并进行软件设计和测试。在硬件设计组装的基础上,经过联机调试和试运行后,进行了大量生产性试验。实践证明该方案正确可行。
The PLC sequence control scheme of the electrical control part of a large ultrafine grinding machine is introduced. Through the analysis of equipment control requirements, the number of PLC input and output signals is determined, the appropriate PLC device is selected and the I / O points are rationally allocated, and the overall scheme of the electronic control part is designed. According to the operation of the equipment to determine the software design process, and software design and testing. On the basis of the hardware design and assembly, after a series of commissioning and commissioning, a large number of productivity tests were conducted. Practice has proved that the program is correct and feasible.
