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.
