From the late 1980s to the mid-1990s, with the popularization and application of computer and network technology and the rapid development of VLSI, gate array and ASIC, the CPU of programmable controller has been developed into 16-bit or 32-bit microprocessors, and the processing speed has been greatly improved. High-speed counting, interrupt, PID, motion control and other functions have been introduced into programmable controller. The programmable controller can meet all fields of industrial production process. The programmable controller has completely replaced the traditional logic control device, analog instrument control device and DDC (direct digital control) control device with minicomputer as the core. Due to the enhanced networking capability, it can be connected with the upper computer, and can also be attached with FLEX I/O or remote I/O, so it is no longer difficult to form a distributed control system (DCS). The ladder diagram language and statement table language are fully mature and basically standardized. SFC (sequential function diagram) language is gradually popularized. The special programmer has been replaced by personal computer and corresponding programming software. The human-machine interface device is becoming more and more perfect. It has been able to monitor and manage the whole plant, and has developed redundancy technology, greatly enhancing the reliability.
