基于国产化MCU和FPGA芯片的小型PLC控制器设计OA

In recent years,domestic small-scale PLC technology has achieved certain development,but the function is relatively simple,without high-speed pulse output and high-speed counting channels,and cannot control electric servo motors and stepper motors.The communication function of the main body is single,which cannot meet the requirements of the field equipment bus,develop a multifunctional small PLC controller based on this current situation.The controller is based on localization MCU chips and FPGA chips,The ontology supports multi-channel digital input and output channels,analog input and output channels,Eth-ernet communication interface,CAN communication interface,RS485 communication interface,SD card communication inter-face,module expansion interface,etc.The digital channel supports functions such as frequency measurement,high-speed count-ing,pulse width modulation,pulse train output/position control,etc,controller can achieve control of electric servo motors and stepper motors,and achieve motion control functions.The module has the characteristics of multiple IO control functions,rich communication interfaces,and small space,which can be flexibly applied in the field of industrial control.
