What are the characteristics of a programmable computer?

Mainly refers to the programming of the CPU.

The central processing unit (CPU) is the computing core and control core of a computer. CPU, internal memory and input/output devices are the three core components of electronic computers.

Its function is mainly to interpret computer instructions and process data in computer software. The CPU is composed of arithmetic units, controllers and registers, as well as the data, control and status buses that implement the connections between them.

The operating principle of almost all CPUs can be divided into four stages: fetch, decode, execute and writeback. The CPU fetches instructions from memory or cache, puts them into the instruction register, decodes the instructions, and executes them.

Programmable computer controller, as a brand new concept, was proposed in the industrial control industry in the mid-1990s. It combines the advantages of traditional PLC and IPC.

It not only has the high reliability and easy scalability of PLC, but also has the powerful computing/processing capabilities and high real-time and openness of IPC. It is a new generation of programmable computer controller that represents Today's development trends in industrial control technology.

Programmable controller PLC and industrial computer IPC have been launched for many years, and they have been widely used in different applications.

In many years of application practice, the shortcomings of PLC's poor computing/processing capabilities, poor real-time performance and openness, and relatively poor reliability and scalability of IPC have been gradually exposed. We are looking for a performance Better controllers have become an urgent need for various industrial users.

PCC, launched by Austrian B&R in 1994, combines the advantages of traditional PLC and IPC. It has the high reliability and easy scalability of PLC and the powerful computing/processing capabilities and relatively high performance of IPC. High real-time and openness.
