9-39
9.3 Engineering Setting Data Items

Setting procedure of Engineering setting data items
When RUN/STOP switching (RKC communication identifier: RS, Modbus register address: 006DH) is set
to “0: STOP (control stop),” Engineering setting data can be configured.
During RUN (control), the attribute of the Engineering setting data is RO (read only).
9.3.1 Precaution against parameter change
If the following parameters are changed, related settings will also change.
Before changing a parameter, be sure to make a record of all the settings (Normal setting
data and Engineering setting data).
After changing a parameter, be sure to check all the settings (Normal setting data and
Engineering setting data).

When the Input type parameter is changed
When the input type is changed, all the setting in the following table will be changed. Reset the settings to
the values that you wish to use.
Input type (RKC communication identifier: XI, Modbus address: 0176H to 0177H)
Items that are initialized:
Data type Items Default value

The Engineering setting data should be set according to the application before
setting any parameter related to operation. Once the Engineering setting data are
set correctly, those data are not necessary to be changed for the same
application under normal conditions. If they are changed unnecessarily, it may
result in malfunction or failure of the instrument. RKC will not bear any
responsibility for malfunction or failure as a result of improper changes in the
Engineering setting.
