NOTE Editing the first address, I/O point address, or catalog information for a plc

Tag
Specifies a unique identifier assigned to each I/O point. The tag value can be
manually typed in the edit box.
Options
Substitutes a fixed text string for the %F part of the tag format. Retag
Component can then use this override format value to calculate a new tag for
the PLC module. For example, a certain PLC module needs to always have an
"IO" family tag value instead of "PLC" so that re-tag, for example, will assign
IO-100 instead of PLC100. To achieve this tag override you would enter
"IO-%N" for the tag override format.
