H系列PLC编程时I/O地址分配的位字关系浅析

Analysis of the Relationship between Bit and Word in H-series PLC Programming

文中通过对H系列PLC编程时输入输出的位编码和字编码具体规定的描述 ,进一步分析了字位之间的有机联系 ,给出了二者之间的换算规律 。

The rules on bit input (output)and word input(output)in H-series PLC programming was described in this paper and further analysis of relationship between bit and word was down too.At same time,the paper showed us an exchanging rule in bit and word and given us two examples to make the relationship and the rule very clear.
