Reading Measurement Values/Statuses

The K7DD can read the measurement values, statuses and setting parameters together at once, using
the Read Variable Area Command.
With the Read Variable Area Command, the
K7DD can read addresses by specifying them one
by one or multiple addresses together by
specifying an area. The latter case is useful as the
read operation can be completed with one
command/one response.
Refer to 7-7 Variable Area Map (P.7-17) for details on the variable area to specify.
The setting parameters can be read regardless of the status of the K7DD. The reading operation does
not affect the K7DD operation.
