An industrial control computer (ICC) is a computer specifically designed for industrial control. Its reliability, anti-interference capabilities, and security meet the requirements of industrial applications. With the advent of Industry 0, ICCCs have become an important tool for realizing intelligent manufacturing. The development of ICCC programs is a crucial step in achieving automation and intelligence in industrial control systems. The following section will introduce the methods for developing ICCC programs.
The control laws of industrial control systems are typically model predictive control, PID control, etc., which dictates that the control algorithm needs to run alongside the operating system within the industrial control computer. In industrial applications, programming languages such as C/C++ are commonly used for program development.
Generally, industrial control computer program development can be divided into the following steps:
Determine the control objective and the required control algorithm.
Once the control objective is determined, a suitable control algorithm needs to be selected based on the specific objective, such as model predictive control or PID control. The selection of the control algorithm also needs to consider factors such as the floating-point arithmetic capabilities supported by the industrial control computer hardware.
Write the program.
Based on the determined control algorithm, the program is written. C/C++ are common programming languages. Depending on the hardware platform, customized programming may be required, such as writing drivers and button responses.
Perform debugging and testing.
After the program is written, debugging and testing are essential steps. Through continuous experimentation and debugging, the program can be improved.
Deployment and maintenance.
After deployment, the program still requires maintenance. This process is lengthy, requiring continuous optimization and upgrades. It also necessitates timely responses to hardware issues and software fixes.
In program development, to ensure the reliability and security of the program, the following principles need to be followed:
Safety first principle.
Because the safety of industrial control systems is directly related to personal and property safety, the principle of safety first must always be kept in mind during program development.
Reliability principle.
When writing a program, its stability and fault tolerance need to be considered to ensure that the program can run for a long time without crashing or encountering exceptions due to unexpected situations.
The principle of operational efficiency.
The control precision and response time of industrial control systems often require the support of efficient algorithms, and efforts to improve program execution efficiency are also very important.
Industrial PC programming needs to be based on actual conditions, especially the coordination with specific hardware platforms. Developing industrial PC programs requires not only a deep understanding of the characteristics of industrial control systems, but also constant attention to technological updates and advancements in the field, learning and becoming familiar with new technologies to ensure the stability, security, and efficiency of the program.
