Box.

one tag per tag set if the tags are registered as tag sets. In this case, the
Yes Button is clicked to register
one tag per tag set.
If the Yes Button is clicked, more tags can be registered at the end of the tag set. In this case, only the tags
will be registered and they will not be registered in tag sets.

When bit settings are selected with tags for NE1A-series Controllers that support EtherNet/IP Unit, they use 1
byte of data.
When two consecutive tags are set for bits in a pair of devices, memory will be allocated as follows and a con-
nection cannot be established.
