Data Break (Command)
The read information is specified one item at a time separated by a break code
(,). The maximum number of items that can be specified is 128. (When the PV of
a timer/counter is specified, however, the status of the Completion Flag is also
returned, and must therefore be counted as two items.)
Batch Reading
The bit, word, and timer/counter status is read as a batch according to the read
information that was registered with QQ.

data is returned. If “PV” has been specified for timers/counters, however, then
the PV is returned following the Completion Flag.
