Starting bit address
A symbol can also be specified for the start-
ing bit address. Only Holding, Work, and DM
Area addresses can be used regardless of
whether a physical address or symbol is
used.
A constant or word address in I/O memory
can be used for the offset. If a word address
is specified, the contents of the word is used
as the offset.
Specifying In brackets, specify the number of words to
offsets for offset the specified starting bit address.
