Editing procedure
An independent memory area (editing RAM) is assigned
for data editing inside the system controller as shown.
First, copy the source data for editing to the editing RAM.
Then modify the data on the editing RAM and save the
editing contents to the specified preset area of EEP ROM.
In addition to the default preset data that has been set
already when shipped from the factory, you can edit the
various data from the already saved data in EEP ROM or
the signal data that is being input at this moment.
(An example shows the case the data stored in the EEP
ROM preset area No.2 is used for editing and the edited
data is stored in the area No.11.)
