摘　　要：近年来,国内小型PLC技术虽然得到一定发展,但整体功能较为简单,普遍没有高速脉冲输出和高速计数通道,不能进行电伺服电机和步进电机的控制,本体通信功能单一,不能满足现场设备总线的要求。基于此现状,研发一款基于国产化MCU和FPGA芯片的多功能小型PLC控制器。本体支持多通道数字量输入输出通道、模拟量输入输出通道、以太网通信接口、CAN通信接口、RS485通信接口、SD卡通信接口、模块扩展接口等。数字量通道支持测频、高速计数、脉宽调制、脉冲串输出/位置控制等功能,可以实现电伺服电机和步进电机的控制,具有IO控制功能多、通信接口丰富、空间小的特点,可以灵活应用在工控领域。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,Ethernet communication interface,CAN communication interface,RS485 communication interface,SD card communication interface,module expansion interface,etc.The digital channel supports functions such as frequency measurement,high-speed counting,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.
