DCS模块实现现场数据的数字化

 关键字：DCS模块       http://www.china-dcs.net/​​

DCS模块是由置于主控机笼和扩展机笼内部的i/o模块及对应端子模块共同构成，i/o模块通过端子底座与现场信号线缆连接，用于完成现场数据的采集、处理与驱动，实现现场数据的数字化。

  DCS模块中继柜内的有I/O即输入输出模块，有DI、DO、AI、AO四种，传输不同信号的量，在有CPU CPS（电源模块）通讯模块等等，在传送到上位服务器中控的操作都是由模块处理后送到现场设备的。   现场信号通过DCS模块进行采集，输送至cpu进行处理并上传到上位机主要有ai模拟量输入（比如转速、调节阀反馈、压力变送器等）、ao（转速控制、调节阀开度指令等）、di（压力或液位开关、泵风机电机阀门反馈等）、do（阀门开关指令、泵机启停指令）、tc（热电偶）、rt（热电阻）当然还有其他的专用模块，比如转速、通讯等等。通过现场点数除以模块带点数进行模块数量的计算。 德科蒙过程控制（武汉）有限公司座机：027-88062221传真：027-88068180邮箱： sales@whdkm.com地址：武汉市武昌区中南国际城D座一单元901室原文出处：http://www.china-dcs.net/a/xwzx/169.htmlPARent;">ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" SANdbox="allow-forms allow-pointer-lock allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C8%3A32768%2C9%3A32776%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C40%3A32&guci=2.2.0.0.2.2.0.0&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=32.0.0&pra=5&wgl=1&adsid=NT&dt=1593591367609&bpp=14&bdt=61&idt=267&shv=r20200624&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&nras=1&correlator=5410479124915&frm=23&ife=1&pv=2&ga_vid=1749968643.1593591368&ga_sid=1593591368&ga_hid=1778508748&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=8&u_java=0&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_nplug=17&u_nmime=34&adx=-12245933&ady=-12245933&biw=1203&bih=586&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21060548%2C21065532&oid=3&pvsid=147546087399245&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&rx=0&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1920%2C0%2C1920%2C1030%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8220&bc=31&ifi=0&uci=0.2q5tko41i13o&fsb=1&dtd=308" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.2q5tko41i13o" data-load-complete="true">
