Specifying
offsets for bit
addresses In brackets, specify the number of bits to off-
set the specified 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.
