Description
Data Type: Unsigned8
Number of view objects of the block.
Data Type: Unsigned16
The revision level of the static data. Increments by
one each time a static parameter changes, or a
change of a table is accepted. Reset to 0 in case of a
cold start (ie if FACTORY_RESET = 1 is set). Set to 1 if
overflow.
Data Type: Octet String
The user description of the intended application of
the block.
Data Type: Unsigned16
The strategy field can be used to identify grouping
of blocks. This data is not checked or processed by
