This thesis proposes to use MODICON's Programmable Logic Controller (PLC) as the control hardware, and use the Unity program editing software that supports IEC61131-3 language to develop and design an easy-to-operate Function Block Diagram (FBD) as a future cement grinding system program The basis for the development of graphical applications of control.
Through the Function Block Diagram (FBD), there is a structured program to realize the program of automatic system construction, and integrate the control process requirements of the automatic cement grinding system to develop Function Block Diagram (FBD), such as: group switch control circuit, raw material conveying stand-alone equipment Waiting for Function Block Diagram (FBD), the operator can control multiple devices on the same screen, and do not need to check complicated logic modules, control and instantly understand the operating status of the equipment, and for the maintenance personnel can quickly find the equipment. It also enables the first-time users to grasp the operation process more quickly, and when the programmers program other systems, if the same equipment is used, it can be used repeatedly without further design, and the program will not affect the In the state of function, the programming screen is concise.
It enables general program developers to complete the establishment of different demand systems in a short period of time, and edit the corresponding Function Block Diagram (FBD) according to their own needs to meet the requirements of automated production. In the increasingly competitive program control market demand, it will improve the company's production. Efficiency and product quality, thereby improving the competitiveness of the market.
