Parameter area 1 (30 words)
The parameter area of each ID
has 30 words and can store a
maximum 128 pieces of
information.
The header of the 30 words
indicates the ID, and data is
arranged in 30-word units in ID
ascending order.
It is necessary to perform
automatic address recognition
again when a slave unit is added
or the ID of a unit is changed.
