Changing (Writing) Setting Parameters - Omron K7GE-MG User Manual

6-7 Changing (Writing) Setting
Parameters
Change the setting parameters using the Write Variable Area command.
The Write Variable Area command can write
single specified addresses one by one, but it can
also write multiple addresses together by
specifying an area. The latter case is convenient,
as the write operation can be completed with one
command/one response.
The area to specify is H'0020 to H'002F. Refer to 6-3 Variable Area Map on page 6-5.
Issuing the command changes and saves the setting
parameters in the non-volatile memory in the K7GE-MG.
However, a power ON reset is required to operate the
Unit based on the new setting values. For example, if
alarm value 1 is changed with the communications
command for changing the setting parameters, a power
ON reset must be performed with a Software Reset
Command, etc. to enable alarm judgment with the new
threshold value.
Therefore, when issuing the command to change the setting parameters, you do not have to worry
about the status, such as whether or not automatic measurement is in progress. However, you should
consider the timing for the reset, such as waiting until any measurement in progress is complete.
