Host Link Commands Section 6-5
(S): Space
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.
Command Format
Response Format An end code of 00 indicates normal completion.
Parameters Read Data (Response)
Read data is returned according to the data format and the order in which
read information was registered using QQ. If “Completion Flag” has been
specified, then bit data (ON or OFF) is returned. If “Word” has been specified,
then word data is returned. If “PV” has been specified for timers/counters,
however, then the PV is returned following the Completion Flag.
Data Break (Response)
The break code (, ) is returned between sections that are read.
