The birth of PLC
With the development of semiconductor technology, especially microprocessor and microcomputer technology, in the early and middle 1970s, a programmable logic controller (PLC) was designed and manufactured. It can complete sequence control, only logic operation, timing, counting and other control functions.
From the late 1970s to the early 1980s, the processing speed of the programmable controller was greatly improved, and many special functions were added, making the programmable controller not only able to perform logic control, but also to control the analog quantity.
Since the 1980s, with the rapid development of large-scale and ultra-large-scale integrated circuit technology, programmable controllers with 16-bit and 32-bit microprocessors as the core have also developed rapidly, and their functions have become stronger and stronger. PLC has the functions of high-speed counting, interrupt technology, PID regulation, data processing and data communication.
In January 1985, the International Electrotechnical Commission (IEC) formulated the standard of PLC.
