开发PLC富余功能实现油箱油温自动恒温控制的研究

Research of Automatic Constant Temperature Control for the Oilbox Oiltemperature by Developing PLC Surplus Function

本文介绍F_1-60MR可编程序控制器富余软件的开,以及应用所开发的富余软件对磨机稀油站油箱油温实现自动恒温控制的I/O口图、主回路原理图、PLC内部逻辑框图、时序图、梯形图及程序清单,并给出了这种方法的控温精度。

The surplus software development about F_160MR PLC and the I/O graph, the main loop principle graph, the PLC internal-logical graph, the time graph, the echelon graph and program of the application software which brings about the constant temperature control for the oilbox oiltemperature of the grinding machine rare-oil station automatically, is described. The temperature control precision using the above method is given.
