Specifying bit
addresses
The word and bit numbers are specified
directly to specify a bit (input bits).
The same addresses are used to access
timer/counter Completion Flags and
Present Values. There is also only one
address for a Task Flag.

The word number is specified directly to
specify the 16-bit word.

Specifying offsets for
bit addresses
*1
In brackets, specify the number of bits to
offset the specified starting bit address.
A symbol can also be specified for the
starting bit address. Only Holding, Work,
DM, and EM 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 directly as the
offset.
