PLC---S7100.200.300 注意事项:
规范的接线及走线,弱信号要尽量与强电信号分开走
模拟量信号线要采用单端接地方式,通信线要采用双端接地方式
热电偶要采用绝缘式的传感器
PLC的供电电源尽量采用隔离变压器
防止直流电源的负端与交流电的零线或大地有任何的接触
所有直流电源要注意要共负端,不共可能会造成采样不稳定,因为没有共同的参考地
231-0HC或235-0KD模块容易采共模电压的干扰,把信号的输入的负端与24VDC的负端短接,可以有效地防止这种干扰
通信线要注意终端电阻的使用
CPU的通信口为非隔离口,与其它设备(变频器)等通信时好加光电隔离器
CTS7200 CO-TRUST CPU224.226/DO.DO.AI.AO.特殊模块 100%兼容西门子S7-200系列CPU;
采用的滤波技术,采样更加稳定 ,,退出带以太网口的200系列,效果更贴近工业4.0.。。。。。
