I. Introduction
1.1 PLC Introduction
PLC or Programmable Logic Controller is a computer device used specifically for industrial automation control. PLC has become an essential component in electrical engineering.
1.2 Introduction to CODESYS
CODESYS is a PLC programming software that can be used in various fields, including automation control, industrial safety, and home automation. It is widely applied in practical production due to its openness and extensibility.
II. Setting up PLC Program using CODESYS
2.1 Installation of CODESYS Software
Before setting up PLC programs using CODESYS, the software needs to be downloaded and installed. After installation, follow the prompts to configure it.
2.2 Selection of Application Field
CODESYS software supports various application fields such as maritime, pharmaceutical, food and beverage industries. When creating a project, choose the appropriate application field based on the actual situation.
2.3 Project Creation
2.3.1 Establishing a New Project
First, open the CODESYS software and create a new project by entering the project name, storage path, and other necessary information.
2.3.2 Project Attribute Settings
In the project attribute settings, select the suitable PLC model and communication module and set the communication parameters.
2.3.3 Project Storage
After project creation, save it to the designated location for future development and maintenance.
2.4 PLC Program Design
2.4.1 Components of PLC Program
PLC program consists of multiple program modules, each with its specific function. Common program modules include I/O modules, communication modules, and data processing modules.
2.4.2 Writing PLC Program Instructions
CODESYS software provides a rich library of PLC program instructions, including logical operations, comparison operations, and mathematical operations. When writing PLC programs, choose appropriate instructions based on the specific requirements.
2.4.3 Defining Data Types
In PLC programming, different data types need to be defined, such as integers, floating-point numbers, and strings. When defining data types, pay attention to data ranges and type conversions.
2.5 PLC Program Debugging
2.5.1 Debugging Process
After completing PLC program coding, debugging is necessary to ensure the program runs smoothly. The debugging process includes setting breakpoints, executing the program step by step, and observing variable values.
2.5.2 Using the Debugger
CODESYS software offers powerful debugging functions, including online and offline debugging. During the debugging process, the debugger can be used to monitor the program runtime status and variable values.
