Screen B appears if you are using Unity Pro software V4.0 or higher.
The Health Block The Health Block field (item 1 in the illustration above) lets you define the first word
or bit in a health table. That table can be up to 8 words (%IW) or 128 bits (%I) in
length. Each bit in the table represents the status of an individual device. The table
below shows how the bits are displayed based on the data type you use.
By default, the table comprises words starting at %IW1.0. If you want to set the table
to bits, you need to specify a %I value in an increment of 16 (%I1, %I16, %I32, etc.).
