Industrial computer is a computer specially used in industrial control system, their development history can be traced back to the 50s of the 20th century, with the development of industrial demand for technology and the increase of industrial automation and gradually formed, from the earliest industrial control system relies on analog technology and electromechanical technology;At the beginning of the digital era, and finally to the rise of the PLC era, the evolution process of the combination of software and hardware from the industrial computer is boilingThis time, we will re-talk about the topic of "whether industrial computers are the basis of automation and whether PLCs are competent".1.1. Overview of IPC:Industrial computer must be known to everyone its full name is "industrial control computer", the so-called "special person" computer is used in daily life, that industrial computer is used in the industrial field;
1.2. Features of industrial control robots:
First of all, in terms of hardware, all the components in the industrial computer are fully industrialized design, with extraordinary anti-interference force, to ensure 7*24h operation in harsh industrial environments
Secondly, the industrial computer has the characteristics of high temperature resistance and cold resistance, and the product is specially designed for industrial scenarios, which can operate under extreme temperature conditions, and can run between -20 and -70 up to
2.Features of 1PLC hardware and software:
The hardware features of PLC (Programmable Logic Controller) include input and output modules, connection of sensors and actuators, and real-time acquisition and output of control signals. The processor (CPU) is responsible for executing the control program written by the user, performing logical operations and making decisions.
2.Application areas of 2PLC:
PLC is widely used in various industrial fields, including but not limited to: manufacturing, energy, transportation, automation, etc.
3.1. Advantages of industrial computer:
Industrial computers usually have high-performance processors and large memory capacity, can handle large amounts of complex data, and it can support a variety of programming languages and development environments, which is more flexible than ordinary computers, and can be used for a variety of customized custom systems.
3.2. Disadvantages of industrial computers:
Due to the high performance of the industrial computer, its hardware and software costs are relatively high, not suitable for some simple data processing tasks, and it has high requirements for real-time performance, the industrial computer may not be able to meet the implementation functions comparable to PLC in some fields.
3.Advantages of 3PLC:
PLC focuses on real-time control, has a high degree of response time, is suitable for real-time high control system, its anti-interference force is very suitable for industrial environments, and finally compared with the hardware and software cost of industrial computer PLC is lower for simple tasks.
3.Disadvantages of 4PLC:
PLC computing power is limited and may perform poorly for complex large-scale data processing
4.1 Common Denominator:
Precise real-time control:Both industrial computers and PLCs are used for real-time control, but PLCs are more prominent in terms of real-time performance.
Communication Capabilities:Both support a variety of communication interfaces for connecting other devices, sensors, and more.
4.2: Difference:
Flexibility:The industrial computer is more flexible, supports a variety of programming languages and development, and is suitable for complex control logic, and the programming language of the PLC is relatively simple.
Scope of application:Industrial computers are suitable for more fields, and PLCs are more suitable for industrial control scenarios with high real-time and stability requirements.
The above comparison aims to highlight the advantages and disadvantages of IPC and PLC and their applicability in different application scenarios. Choosing the right equipment depends on your specific control needs and budget considerations.
