Writing Setting Parameters

The Write Variable Area Command allows you to change the setting parameters.
With the Write Variable Area Command, the
K7DD can write addresses by specifying them
one by one or multiple addresses together by
specifying an area. The latter case is useful as the
write operation can be completed with one
command/one response.
Sending this command changes and saves the
setting parameters in the non-volatile memory in
the K7DD.
Some setting parameters can be reflected
immediately after writing, and others can be
reflected after restart. Refer to the tables in
Variable Area Map (P.7-17) for information on
which parameters can be reflected immediately or
after restart.
For example, Feature Calculation Cycle is a
parameter that can be reflected after restart.
If the value of the Feature Calculation Cycle
parameter is changed with a communications
command (for changing setting parameters) after
transition to the operation stop status, the power
ON reset process must be executed by the
Software Reset Command or other ways.
