For example, L800 would indicate to the driver that the group
contains digital elements and that the first element of the
group is 800 in the controller. A tag could be assigned to any
of the elements up to, but not including, the limit of the group
size plus the starting address. If the group size in this case was
240, L1039 would be valid for a tag assignment, as would L800
or any number in between.
Harmony limits the data group size by Harmony data type. The
MICRO-DCI PSD further limits data group size by related
MICRO-DCI controller model and data type (Table 4-1).
