PLC control is inseparable from the design of electrical circuit diagrams.How to standardize the use of electrical graphic symbols and text symbols requires us to develop the habit of drawing according to national standards.Older designers are accustomed to using the original old signs and symbols,and use the new national standards to cause the phenomenon of mixing the old and the new.And those who graduated in the 1990s just had to master the new standard.
PLC控制,离不开电气电路图的设计,电气图形符号、文字符号如何规范使用,需要我们平常养成按国家标准画图的习惯。年纪大的设计人员用惯了原来的旧标志图形符号,使用国家新标准重重造成新旧混用现象。而九十年代毕业的人只须掌握新标准即可。
