Omron CJ1W-EIP21 用户手册

There are both input and output tag sets. Each tag set can contain only input
tags or only output tags. The same input tag cannot be included in more than
one input tag set. 

Each tag set can contain one or more tags. 

■

With basic Network Configurator procedures, each tag set contains only one
tag. 

■

As shown below, tags can be created in groups. Each tag set can contain up
to 8 tags totaling 20 words for the CJ2M or 722 words for other CPU Units.
