Description

1、 Question raising
The main application of programmable controller technology is in automation control engineering. How to comprehensively apply the knowledge points learned earlier, and reasonably combine them into a control system according to actual engineering requirements? This article introduces the general method of forming a programmable controller control system.
2、 The basic steps of designing a programmable controller control system
1. The main content of system design
(1) Develop technical conditions for the design of the control system. The technical conditions are generally determined in the form of a design task book, which serves as the basis for the entire design;
(2) Choose electrical transmission forms and actuators such as electric motors and solenoid valves;
(3) Select the model of the PLC;
(4) Develop input/output allocation tables for PLC or draw input/output terminal wiring diagrams;
(5) Write software specifications according to the requirements of system design, and then use the corresponding programming language (commonly used ladder diagram) for program design;
(6) Understand and follow user cognitive psychology, value the design of human-machine interfaces, and enhance friendly relationships between humans and machines;
(7) Design operation consoles, electrical cabinets, and non-standard electrical components;
(8) Write design instructions and user manuals;
According to specific tasks, the above content can be adjusted appropriately
