Abstract: 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.
Key words : localization; PLC controller; motion control

引言

隨著我國(guó)自動(dòng)化水平的提高,,PLC的應(yīng)用受到越來(lái)越多行業(yè)開(kāi)發(fā)者的重視,然而國(guó)內(nèi)的PLC市場(chǎng)大部分被國(guó)外廠家所占有[1],。2022年國(guó)內(nèi)PLC市場(chǎng)規(guī)模為137.8億,,其中小型PLC市場(chǎng)75.5億,占比54.8%,,市場(chǎng)主要被西門(mén)子,、歐姆龍,、三菱、施耐德等國(guó)外廠家所占領(lǐng),。近年來(lái)受到美國(guó)實(shí)體清單以及國(guó)際局勢(shì)的變化的因素[2],,研制國(guó)產(chǎn)化PLC具有重要意義,國(guó)內(nèi)許多企業(yè)開(kāi)始攻克PLC關(guān)鍵技術(shù),,從而開(kāi)啟了PLC國(guó)產(chǎn)化的征程[3],。

根據(jù)IO點(diǎn)數(shù),PLC可以分為小型,、中型,、大型三類(lèi),其中大型PLC主要面向項(xiàng)目市場(chǎng),,如電力,、礦山、冶金等領(lǐng)域,,需要強(qiáng)大的IO點(diǎn)數(shù)和復(fù)雜的控制能力[4],;小型PLC主要面向OEM市場(chǎng),在紡織,、包裝,、機(jī)床領(lǐng)域或者小型局部控制器系統(tǒng)占有很大的市場(chǎng)比重,小型PLC隨著市場(chǎng)需求,,得到越來(lái)越多重視,,市場(chǎng)上有多款小型PLC模塊發(fā)布[5]。
